Stephen Posted February 14 Report Share Posted February 14 Aircraft Review : JRX Design Bell 407 v1.30 for X-Plane 11 and 12 A derivative of the Bell 206L-4 LongRanger, Bell 407 is a four-blade, single-engine, civil utility helicopter that uses the four-blade, soft-in-plane design rotor with the composite hub developed for the United States Army's OH-58D Kiowa Warrior, instead of the two-blade, semi-rigid, teetering rotor of the 206L-4. So the breed line is from the famous "Jetranger", but the 407 is the far bigger and powerful relation to the family. The Bell 407's fuselage is 8 inches (20 cm) wider, increasing internal cabin space, and includes 35% larger main cabin windows. The more powerful Rolls-Royce/Allison 250-C47 turboshaft allows an increase in Maximum Takeoff Weight and improves performance at hotter temperatures and/or higher altitudes. The helicopter has standard seating for two crew and five cabin seats. In 1993, Bell began the development of the New Light Aircraft as a replacement for its Model 206 series. The program resulted in the 407, a development of Bell's LongRanger. A 206L-3 LongRanger was modified to serve as the 407 demonstrator. The demonstrator used hardware for the 407 and added molded fairings to represent the 407's wider fuselage then under development. The demonstrator was first flown in 1994, and the 407 program and was publicly announced at the Heli-Expo in Las Vegas, Nevada, in January 1995. The first 407 prototype (C-GFOS) then accomplished its maiden flight on June 29, 1995, and the second prototype (C-FORS) followed on July 13, 1995. After a short development program, the first production 407 (C-FWQY/N407BT) flew on November 10, 1995. Since then almost 1500+ aircraft have been built. In 2021, only three years ago JRX Design started in the X-Plane Simulator with the dual SA 341B and SA 342J Gazelle, then their next release was the Messerschmitt-Bölkow-Blohm Bo 105 DBS-4, a big name, but also a lot of helicopter, which was updated only 12 months ago to X-Plane 12. All sensational and quality designs. This is JRX's latest release with the Bell 407. Notable is that the release(s) are separate for both the X-Plane 12 version or the X-Plane 11 version, as they are not packaged together here. We will of course focus on the XP12 version for the review, in details the X-Plane 11 is identical, but missing the X-Plane 12 dynamic features. This is not the first Bell 407 for X-Plane. That was the excellent Bell 407 from Dreamfoil Creations, a standard bearer for it's time with a huge feature list and flying dynamics. Currently still only X-Plane 11, but with the release of the terrific Schweizer S300CB, it noted the developer was back in a big way, and he notes that the Bell 407 (and the AS350 B3+) are now being developed for X-Plane 12, expect in a few months. So that obviously sets up a quandary, which would be the best B407 to buy? A hard one even for me, as both as we shall see are very highly quality developed machines. The B407 from JRX is available now and for X-Plane 12, but the Dreamfoil 407 will have a bigger feature list and personal familiarity... it is a very, very tough choice. Note, that since this review has been published, JRX Design has since updated the 407 to v1.30 (forget v1.10 as it was a non-starter). There were a few new additions, the biggest new feature was the CINEFLEX camera feature, and that item has now been included in the review. Design wise JRX have a superlative quality record, and to scale, and that aspect shows here. The 407 is beautifully done in modeling terms with excellent glass. Odd here though is you can't hide the glass reflections (inside or external), but it is still very well done with both front and rear doors with window (opening) hatch inserts. The huge fuel filler is excellent. Notable is that the riveting is drawn on and not modeled with highlights, same with the engine cover latches. It's well done but noticeable, but the external panel bolts are nicely 3d. The engine internals are also images, again highly realistic, so you admire them and are not as so distracted by them being only 2d Rear tail boom, horizontal stabiliser and upright tail support are well modeled, with the original orange/white tail-skid. The heart of a helicopter are the rotors and their assemblies.... The main rotor is a 35 foot diameter, soft-in-plane flex beam (flapping flexure) type yoke/hub with four interchangeable blades. Elastomeric technology is incorporated and allows for blade movement. The blades and yoke are all composite materials. The rotor is designed to rotate at 413 RPM at 100% Nr. As rotor heads go it is very, very simple design, just the tower and four pushrods. Plate construction is really good, as are the arms, but we are going to lose points because only the collective bite is animated (13 degrees of twist), shame as we know the Dreamfoil 407 is fully animated, but the movements here are good. Rear tail-rotor is intricately designed, great detail and fine work. The yaw animations are also well done and visible. All doors are animated, can be opened externally and internally, and they can also be removed, but only all and not individually. Left side also takes away the cam centre panel, for a very wide open space for the Medi-Vac. So you really do wish for more selection on which doors you want removed as you can't slide the rear doors open in flight, missing also is the long and short window door panel option. Rear cabin seats five, or four chunky seats and a tight centre child seat in the rear. Default colour is a light grey with the very nice "Bell" logo on the seat back, the trim material is all very nicely done. Seating colours change to the selected external livery, with four choices in Light Grey, Red, Green and Dark Grey. The familiar restricted cabin roof is well reproduced here, making the rear cabin feel very authentic to those familiar with a 206/406 environment. Forward pilot seats are also very chunky for a helicopter, but very well designed and created. Again the materials are of a quality nature, a feel real effect if viewed in closely of the excellent chosen materials, the above roof switch and CB-Fuse panel is also excellent. All circuit breakers are active and animated. Side doors are beautifully realistically molded, with the authentic bell 407 logos and opening slide window, same in the rear. There is the option for single or duel controls, the left side pilot's cyclic and collective are very basic, with just a throttle built in. The right side pilot has a more detailed collective head, with FLOAT activation and lights with SEARCH, LDG (landing) and Start/Disengage switch. Chunky could also describe the instrument panel, for a small helicopter the 206/407 instrument panels are massive. But the instrument arrangement is quite simple. Top left is a Radio Altmeter, Engine readouts (TRQ - Torque, MGT, NR/NP - RPM, Davtron Clock/OAT/Volt meter, Fuel PSI-AMPS, FUEL Qty and Gearbox and Engine Oil pressure/Temp). Flying instruments include Airspeed, Artificial Horizon, Altimeter. Main NR/NP Tachometer dual gauge, Bendix/king HSI (Horizontal Situation Indicator), Vertical Speed instrument. OBS (Omni-Bearing Selector) for ADF 1/2, OBS NAV 1 and Turn rate dial. Lower is the avionic stack, with a custom GNS 530, KX 155A COM/NAV 1 radio, another KX 155A COM/NAV 2 radio, Bendix/King KMA 30 radio, Bendix/King KT74 Transponder and bottom (flat) a Bendix/King KR87 ADF radio. The metal rudder pedals are also highly designed and have pretty Bell logos. Panel can be set in either a light or dark tone There are two sets of headphones, in that their cables drag across the cockpit and obscures the instrument panel, you can click (lower volume) to hide the right headset, but you can't click on the left co-pilot one to hide it? so it hangs there! and right in your view line (It can thankfully be hidden another way as we shall see later). v1.20 and the Co-Pilot headset can now be thankfully also hidden directly via a "hotspot" click. Power on and the panel is beautifully done, love the instrument contrast to the red radio readouts. Then simply glorious at night! Caution Warning Panel (CWP) is very authentic, you can also test the systems via the button right panel. CWP can be set to BRIGHT or DIM illumination. Other internal lighting includes rear bulkhead adjustable spot light, plus the same as a cabin (switch) light, rear cabin lights again look very nice in the darker light, single overhead panel switch, or the individual rear switches can be used. Overhead panel lighting is again sensational. Menu To access the menu, you press the "Tablet" button on the far right top of the instrument panel. It is in the design of the RWP GTN 750 module. The tablet is extremely well intergrated with a support arm to the instrument binnacle. There are four option tabs on the left; MENU 1, MENU 2, RXP TAB, Avi TAB and LIVERIES. MENU 1 You could call Menu 1 the options tab set into five categories (not labeled). First two, with first the Static Elements, Covers, Tiedowns and Flags, second is the external "GPU" (Ground Power Unit). Note the "Rotor Park Brake" has to be down to activate the Static Elements. Next category covers the pilots and passengers; you have "Fly With Copilot" that puts a crew member in the left seat, notable is when you do this that headset disappears from your POV. You also have "Crew Helmets" but those pesky hanging headsets then return... damn. Pressing "Crew Headsets" will hide only the Pilot's headset, but not the Co-Pilot's. Final option here is the "Passengers", which inserts two lovely ladies in the rear cabin If you adjust the X-Plane "Weight & Balance" menu, it makes no difference or adds in NO more passengers or cargo. In this area the JRX is limited in options Next category covers options; "Dual Flight Controls", and Doors ON/OFF... Under the rear there is a large "Searchlight", or you can have the "Emergency Floats" installed on the skids. There are upper and lower "Wire Cutters" and last is the "ROTOR DAMPENER" cap. New in v1.20 were some very nice rear "Bear Paws" Last category is the set of options for the (optional) Reality RXP GTN 750. There is also a "Autopilot Unit" or Stability Augmentation Systems (SAS), this panel is placed lower right on the instrument panel. Last two options here is the "AviTab" tool (Plugin required), and the selection of the Light/Dark instrument facia. Also on the right side of "Menu 1" are three "Engine Exceedances" readouts, these can also be reset in TRQ (Torque), MGT and NG RPM Listed top of the panel is the current "Version" MENU 2 In this tab you set the aircraft's configuration. Top is the "Fuel Load" in 1/4, 1/2, 3/4 and 1/1 or FULL. Lower left is the changing weights as you select the (Fuel) and Weight/Payload selections right, "ALL UP WEIGHT" and "MAXIMUM TAKEOFF WEIGHT" must balance. Lower are three options with CofG (Centre of Gravity), "Vibrations" Off-x1, x2,x3... last is the selection of the FOV or "Field Of View". RXP/Avi TAB Are both quick button selections of the Reality WP GTN 750 and the Avitab tool LIVERIES You can select your livery via the tablet, and it gives you an image of the 407. There are 21 liveries, that covers a wide spectrum of services and countries, all are excellent. CINEFLEX A new feature added to the JRX B407 in the update v1.30, was the excellent CINEFLEX camera system. The Cineflex V14 is a 5-axis gyro stabilized camera system that delivers images completely free from even the smallest vibrations. It has a Sony Cinealta HDC 1500 camera integrated in the carbon-fibre housing that rotates a full 360°, and all movements are operated from within the helicopter. The first place you would look to activate the camera is the JRX Menu, but it's not located on there? The Camera system is activated by the "Camera System" switch, on the overhead panel, row below the circuit breakers/fuses, far right. Switching it on comes with a disclaimer from the developer... it will deliver a 25% FPS hit on your framerate (any internal to external X-Plane viewpoint, usually has this same negative effect). It is a significant hit, so if the CINEFLEX is not in use it is best switched off. Activated you get the camera pod assembly now visible, slung under the nose of the B407, the modeling is excellent with the detail and the quality of the camera system. On the left side of the instrument panel, there is now positioned a cowled screen and operators panel... The panel has two sets of camera operation knobs, and four buttons. Power, Overlay, Reset and Park. "Power" is to switch on the system, "Overlay" puts a frame and recording data on the screen, including REC, Timecode, Resolution, Camera Coordinates, Airspeed, Heading, Altitude, Track, (camera) Pitch & Zoom "Park" will foldup and store the camera rearwards, "Reset" will set the camera to it's forward "ready" mode. Left small knob is the "Zoom"... 0%-100% Right is the knob/joystick to adjust the camera angle, ROLL, ROTATE and UP and DOWN angles. All the camera movement controls can be set as commands, for keyboard or joystick (HAT) actions, this allows easier control while flying. The CINEFLEX is expertly done, and a great addition to the 407. ___________ Flying the Bell 407 If you open the JRX 407, it will have the annoying habit of just shutting down again? even if the "Start with engines running" tickbox is active. There is a trick here... The issue is caused by the "Idle" button and throttle being set to closed, this is the shutoff point to kill the engine. To start you have to de-click the "IDLE-REL" and give the 407 a bit of throttle (80). Once running, then you can go back to the idle stop, but don't press the IDLE-REL, if not it will just shutdown the engine again... or your back to square one. The "Start" switch is on the same collective, and as long as the fuel is on, then a press and hold of the switch is all that is needed. At first you don't think it is going to fire, then at once around 50% NR rpm, the Allison 250-C47 turbio-shaft engine (813 shp (606 kW)) gets itself together and your in the flying business... its all a FADEC-controlled engine (Full Authority Digital Engine Control), as the FADEC system is designed to reduce pilot work load and increase engine reliability by fully automating the start procedure, and holding engine parameters to tighter tolerances in flight. It feels excellent in this JRX machine... .... then twisting the throttle to "FLY" will increase the NR % to 100% Does the JRX 407 sound good... brilliant in fact. The start whine is excellent, so is the throttle adjustments through the spectrum, then the full rpm chop is really, really good, I've flown on a 407 (and a 206) and it is as good as you will get. I couldn't get any noisy internal blade slap, but external blade sounds in movement when in flight manoeuvres are excellent. Whoa! off the ground with a bit of slight cyclic back, and a feel upwards movement of the collective, and you go into a perfect hover... ... "Oh I like this!" I've had my time with wiggly nervous helicopters for a fair while, "This one is smooooth". Already happy, a bit more collective and a push forward of the cyclic and you are up & away. 206/407 usually need a bit of low nose to get them moving... not too much here and the speed builds very quickly. Bell later replaced the tail rotor pedals with the taller and slightly closer-to-the-pilot versions, as many pilots complained they were too high, as they preferred the 206 pedals than the 407's. The Bell 407 has a maximum speed of 140 kn (160 mph, 260 km/h), with an economical cruise speed of 133 kn (153 mph, 246 km/h). The range is 324 nmi (373 mi, 600 km) with a service ceiling of 18,690 ft (5,700 m). There is the vibration option... OFF is no vibration, x1 is not really a lot, x2 is about perfect as x3 is very, very noticeable shaking, really it feels like your blades are coming loose! I was very impressed with the Autopilot Unit or Stability Augmentation Systems (SAS). It has had some fine tuning in v1.10, but it felt fine to me... you can LVL (Level) then hit the AP, then HDG (Heading) and ALT (Altitude) and the transition in flight is excellent, only a slight lift as you go to the auto system. V/S (Vertical Speed) changes are 5 points either way, but honestly, if your not climbing high, then unlock the ALT and add a little collective to go up, then reselect ALT at your set altitude, the same to go down with less collective. Coming out of auto is good as well, but you need to disconnect the HDG and ALT selections before you disconnect the AP itself for a smooth transition, or it bumps coming out. Heading changes under the SAS are nice and smooth, long and with not any tight jumpy turns, so excellent... yes very impressed. Really the 407 is so nice to fly manually (balanced when trimmed), you won't rely on the SAS, it is a relaxing controls machine, even distances are easy. Time to head back to the Jay Stephen Hooper Memorial Heliport. The 407 has a reputation for solid control feel in flight. That, combined with plenty of power, makes the 407 a real performer. The 206 (Jetranger) feels heavier than the 407 on the controls, so most pilots prefer the 407's flight control’s hydraulic boost, it is quite heavy if you turn the assisted system off. The Bell 407 is not a low-inertia system, it is also not a high-inertia system either like the JetRanger. So the feel is set somewhere in between, in making your approach it can be quite different. Autorotating the 407 going down I found there was still a high degree of maneuverability during the glide (power off), then the transition to Effective translational lift (ETL) was okayish, as you have to be aware on the loss of speed to avoid too much sink, so it's best to transition further out than closer to the pad in case of a sudden loss of lift. The flare and touchdown also requires a different technique than in the JetRanger. Timing is more critical because less energy is stored in the lighter-weight spinning rotors and the more collective pitch is used to cushion the helicopter’s touchdown. In addition, the pilot holds the helicopter in a nose-high attitude and touches down on the heels of the skids. It’s a fairly standard procedure for a lower-inertia rotor. One warning though is the 407 in the low hover is very susceptible to the swing effect, "Mast Bumping" is only present with a 2 blades rotor ...like R22 , R44, B206, but I found here the pendulum effect was very pronounced, the wrong (too heavy) input, and the 407 will swing quite violently, with the obvious results, so keep the final inputs extremely small, even pull away and do a new approach to get the procedure right. A few hours rest and I am airborne again, now twilight... The 407's external lighting is excellent, except for in one area. There is a "Landing" light in the nose, and two amazing flashing strobes underside, rear red beacon and Navigation/Strobes on the horizontal stabiliser fences, the best though are the fantastic "Logo" spots on the side, I totally absolutely loved the lit logo look at night! It is mostly excellent, but the collective switch "Spotlight" created nasty ant lit marks all around the nose and windscreen, so you need to keep it switched off. Now darker, and I am cruising low and fast over the Freeways & Highways Los Angeles County... my favorite Heli-Pilot pastime, the 407 is simply brilliant here, easy to cruise... did I say fast. In roles (or role-play) you are restricted here by the JRX door arrangement, there are no sliding doors on the rear, and not being able to individually remove, say the rear left door, restricts your role playing. Scouting for "News" I am playing a version of the "Nightcrawler", yes the movie , as I love this livery and the cruising above the LA landscape at night. I would have loved an open door, even a cameraman shooting the streets, but there is not even a Medi-Vac version, so it all feels all a bit limited if you wanted to be part of the action. So the JRX Bell 407 is excellent to fly, even say a novice could handle the aircraft and enjoy it's abilities... too benign, no I didn't get that feeling at all, it just felt right and the 407 was a totally enjoyable dynamic experience... then what a way to end the night flying with a visit to that famous "Hollywood" sign... perfect. _____________ Summary The Bell 407 is a four-blade, single-engine, civil utility helicopter that uses the four-blade, soft-in-plane design rotor with a composite hub. So the breed line is from the famous "Jetranger", but the 407 is the far bigger and more powerful relation to the family. The release(s) of the JRX 407 here are separate for both the X-Plane 12 version or the X-Plane 11 version, as they are not packaged together. So make your choice wisely as they both cost the same. JRX Design are now very accomplished developers, the Bell 407 is their third release for the X-Plane Simulator, after the earlier dual SA 341B and SA 342J Gazelle and the Messerschmitt-Bölkow-Blohm Bo 105 DBS-4. Notably the aircraft is created to a very high standard, beautiful modeling and lovely intricate details to scale. However rivets and engine fences are images and not 3d, but the main exterior bolts are modeled. Rotor hub is exceedingly well designed, but only has semi-animations for (twist) collective, and tail yaw. Glass is excellent (maybe the rear windows are bit dark) and there are no reflections disable for the internally or externally for the windows. Cabin and instruments are exceptionally well done, and all is very quality work in feel and look, but there are restrictions with only a singe door hide, and there are not many options for different fitout versions (Medi-Vac, lift hook) and role-playing that is mostly common with Helicopter packages. Lighting internally and externally is again excellent, but for ant whites around the frames with the spotlight feature. Although the official Bell 407 Manual and Procedures are very nice (authentic), a JRX Design manual was also required here. The updated v1.30 also comes with the sensational CINEFLEX camera system, hung on the nose, you have a full control of the camera and it's storage, v1.30 also has some other nice visual and menu tweaks as well. The JRX Bell 405 flies very well, I loved it as it was certainly not a edgy machine to fly, too benign, no I don't think so, so great for first timers and novice fliers, performance and dynamics feel also perfect. Would I like JRX Design to also do the famous 206 Jetranger? After this 407 I certainly think so, as it would be an excellent idea to do a fly off of their different capabilities, but more options overall would be nice. I love the 407, to a point now it is my current favorite helicopter to fly, I don't love niggly machines, I want to fly, hover and do things without the stress, throw in the sheer quality and X-Plane 12 realism and the JRX Bell 407 is a worthy winner... highly recommended. ________________ The Bell 407 by JRX Design v1.30 is NOW available! from the X-Plane.Org Store here : JRX Bell 407 for X-Plane 12 Priced at US$35.99 Requirements X-Plane 12 (not for XP11.

Sirio72 Posted March 5 Report Share Posted March 5 Hi Stephen, great review, so well detailed I'm surprised the replay feature wasn't mentioned. Just out of curiosity, if you have tried this function which in my opinion, compared to other simulators, is the best ever created and easily manageable, have you noticed that the sound is absent or a subtle ambient noise is reproduced if you start a replay from the beginning of the flight? No problem if you start a replay session with the engines running, then everything works well (I mean the engine and rotor sound), perhaps the volume is too high and not very dynamic when moving away from the external observation point but at least audible (xp12 version, don't know if xp11 version is also affected). I recommend you try it because with no helicopter currently available on the store that I purchased, except the JRX bo-105 and the 407, what is described happens, except for the JRX Gazelle that is the only Jrx aircraft with no sound problem in replay. A shame given the high accuracy of the 3D models. What do you think about it? I'm curious. Greetings, Sirio Quote Link to comment Share on other sites More sharing options...
