Aircraft Review : Mudry CAP 10C by Avia71


The Mudry CAP (Constructions Aéronautiques Parisiennes) 10C is a two-seater training aerobatic aircraft that was first built in 1970 and was still in production as late as 2007 under the Apex banner.


It is a very renowned aerobatic aircraft that has had many numerous and well known European champions that have started aerobatic careers on a Cap 10. This 10C version had the updated and improved structure with a carbon-fibre wing spar within its wooden construction to give the aircraft less weight but with more strength to the airframe.

Avia71 (Laurent) has already delighted us with his lovely Fournier RF 5B Glider and the Extra 300, both in the same genre of small glider or aerobatic aircraft and continues his same pattern here with this CAP 10C. The same is said that with the CAP 10C it is like his last developed aircraft in that he has a personal connection to the actual aircraft that is reproduced here with the French registered F-HEBV owned by the aero club of Bernay France, but his two collaborators also have had close associations with CAP 10c's in the several championship winner Thomas with the F-GNVC registered aircraft and Joshua with an G-CPXC example of the two hundred current CAP 10c's built.


Most aerobatic aircraft are mostly single-seaters, but the CAP here is a trainer or two-seater stick and rudder aircraft to learn the basic skills of aerobatic manoeuvres in a safe environment, but with two pilots on board that also adds in weight and changes of aircraft's balance.

As with any reproduction of a real aircraft this 10C is very good. A lot of effort has gone into the minute detail as you would expect. It is not the complete extreme detail you get sometimes now but it is overall very good, and remember wooden construction is very hard to replicate compared to metal or composites. The 10C is a tail-dragger and so you will need all of those tail-dragger skills


To highlight details there is a lot of great worn wear looking areas in panel fit and joins to add in to the authenticity. The aircraft build plate is very well done and adds in that personal aircraft feel.


Mudry_CAP_10C_Detail 5.jpgMudry_CAP_10C_Detail 6.jpg


There is a very good aerobatic sight on the left wing and they are there to allow you to watch the angle of the horizon while watching this outside reference point.


The glass canopy shows you how far X-Plane's glass and reflections have come in the last few years. Beautifully done and highly realistic, more on these reflections later.

Instrument Panel

The instrument panel is very 70's basic, but modern as well. It is set up for aerobatic flight and all mostly focused on the flying pilot.


Mudry_CAP_10C_Panel 1.jpgMudry_CAP_10C_Panel 2.jpg

Mudry_CAP_10C_Panel 3.jpgMudry_CAP_10C_Panel 4.jpg


Detailing is excellent as the Instruments are all large and easy to read and all have lovely reflections. This is a serious stick and rudder aircraft and that aspect is highlighted here, and note the detail is not restricted on what you can see, as behind the panel there is some excellent work as well...  good work is all in the detail.


Mudry_CAP_10C_Detail 9.jpg



Mudry_CAP_10C_Panel 5.jpg  Mudry_CAP_10C_Panel 6.jpg


Instrument layout is slightly different from the normal standard six arrangement, it is a mixture of flying instruments and engine output dials.


Top row from L to R gives you a RPM dial and then next right is the Speed dial in Km/h, then the Altitude dial and finally another Altitude/Air pressure dial.

Lower row L to R is the Manifold Pressure/Fuel Flow gauges, Turn coordinator, Vertical Speed and acceleration dial in G's...  note the missing Artificial Horizon instrument as it is part of the turn coordinator instrument.


Centre panel is another G metre in units and a MEV Acceleometer. Left centre panel is in a basic Communications radio top with a Garmin GTX 320A transponder below...  lower is the intercom (headset) controls which also controls your external and internal sound volumes.


Far right are four dials that includes top left, Volts, Amps and both fuel tank gauges - Top right, Hour(Hobbs) meter - Bottom left, Engine EGT, CHT and Oil Pressure and temperature - Bottom right, co-pilot G-acceleration dial.


Lower panel is switch gear left and fuses right.


The panel can be set up two ways with the aerobatic G-Meters (left) or two navigation instruments in a VOR finder top and heading bottom (right).


Mudry_CAP_10C_Panel 7.jpgMudry_CAP_10C_Panel 8.jpg


Another neat trick is you can have "headset" mode which gives you the roar of sound or the muted headset sounds, This is done by pressing (or plugging in the headset) on the bottom left and right sides of the instrument panel.


Mudry_CAP_10C_Audio 1.jpgMudry_CAP_10C_Audio 2.jpg



The menu tab is the "Remove before flight" red tag on the centre left of your screen...


Mudry_CAP_10C_Menu 1.jpg


This opens up the menu dialog box with five tabs. These include: Settings - Checklists - Weights &Balances - Failures - Tips & Tricks


Mudry_CAP_10C_Menu 2.jpgMudry_CAP_10C_Menu 3.jpg


Overall there isn't a huge amount of options, but for what there is it is all set out very well.



There are two major settings with doing aerobatics with "Cat A" (Aerobatics) and "Cat U" (Utility). These selections allow you to quickly set up the aircraft for either their Aerobatic or Utility roles in one selection. There is a very comprehensive set of documents including a "Aerobatic Basic's" manual that teaches you how to fly the aircraft well in the aerobatics mode. The manual is very good as well in this area with aircraft data and procedures, but I would have liked more information on the instruments as they are quite different from the standard panel fittings and many of the instruments installed here are related to aerobatic flying?


Mudry_CAP_10C_Menu Settings 1.jpgMudry_CAP_10C_Menu Settings 2.jpg


Selecting the different configuration for either the aerobatic or utility roles then changes also the fuel selection or Centre of Gravity (CoG) in the aircraft by closing off the rear tank, changing the centre instruments and setting category limitations. You can either start the aircraft in cold&dark mode or ready to start.



The checklist menu is very good and comprehensive, it covers all aspects of the routines from cold to shutdown. You navigate via the arrows on the bottom of the page or via the main front menu on the cover.


Mudry_CAP_10C_Menu Checklist 1.jpgMudry_CAP_10C_Menu Checklist 2.jpg



The Weights&Balances menu is also very good but a little basic .


Mudry_CAP_10C_Menu W&B 1.jpgMudry_CAP_10C_Menu W&B 2.jpg


The important note here is the two centre of gravity zones that cover the different settings for Aerobatics Cat A (brown) and Utility Cat U (blue). You have to set the aircraft up withing the brown zone for aerobatics and that includes empyting out the rear fuel tank and the careful selections of pilot(s) and luggage weights.


Mudry_CAP_10C_Menu W&B 3.jpgMudry_CAP_10C_Menu W&B 4.jpg


You can have one pilot, or two pilots (trainee) and even swap them around in the various seats and adjust all their weights, I do recommend only one pilot for serious aerobatics as the weights are too high with both bodies in there and you feel the differences of weights when throwing the aircraft around the sky.


Failures and Tips&Tricks


The "Failure" menu has to be switched on by being in the Cat A setup. This is for trainee purposes in that the aircraft will introduce failures in how many (quantity), Training duration (in distance not time) and to note on screen of any of the failures.


Mudry_CAP_10C_Menu Fail 1.jpgMudry_CAP_10C_Menu Hints 1.jpg

Mudry_CAP_10C_Menu Hints 2.jpgMudry_CAP_10C_Menu Hints 3.jpg


Finally there is a "Tips&Tricks" menu that shows you various tricks and where certain things are situated on the aircraft, and it is quite good in finding those extra switches hidden behind such things like fuses.


Flying the CAP 10C

The CAP 10C is a tail-dragger, so that means it can be quite a handful on the ground... visibility is very restricted in this aircraft when taxiing as well. You can't lock off the tail-wheel, so taxiing is very authentic, but quite hard to get right in that you need speed or air over the rudder to turn, so a run forward to turn is constantly required and even then your turns are quite wide.


Mudry_CAP_10C_Flying 1.jpgMudry_CAP_10C_Flying 2.jpg


The look left and down does work, but it is still hard to follow a hidden yellow centre line, so even lining up on the runway is a bit of a guessing game.


The 10C is damn tricky to get airborne. There is a single flap setting to help lift (three settings in UP - T/O - LDG), but the tail refuses to lift until you hit 60Km/h, even a slight push forward of the stick to help it and it still refuses to budge. Tracking is hard as well and you need to counter a lot of different forces in the lightness of aircraft, airstream over the rudder, asymmetrical power and that poor view forwards...


Mudry_CAP_10C_Flying 3.jpgMudry_CAP_10C_Flying 4.jpg


...   and I will put the view forward that there has been a lot of changes to the X-Plane performance in this area in X-Plane11 (more so in the latest 11.10 beta) on runway ground effects and the "wobbles" and I think there is some cause of effect with this aircraft in this role as it is soooo light and nervy.


So it is tricky to get right the first time, even the second...  and the third.


Mudry_CAP_10C_Flying 5.jpgMudry_CAP_10C_Flying 6.jpg


Once in the air and trimmed (electric between the seats) everything resumes to complete normality as the controls are quite sweet and active under your hands and feet.. The only small annoyance is the wheels keep on rotating unless you hit the brakes to stop them.


As you would expect this is a throw around in the air aircraft, the 10C sorts of grows smaller around you as you focus more on the flying and it just feels tighter and tighter with the stick and rudder movements with your ongoing flying.


Mudry_CAP_10C_Flying 7.jpgMudry_CAP_10C_Flying 8.jpg


I have been trying out a few VR (Virtual Reality) headsets lately, and make no doubt that one aircraft that is just built for VR flying is this CAP 10C, it would be just brilliant and the VR would be highlighted more by the excellent reflections of the canopy around you.


Mudry_CAP_10C_Flying 9 LG.jpg


Your aircraft setup balance is of course very important and it totally absolutely affects the way you fly the aircraft...


There is a great popup in the middle of the panel to show you the best aerobatic manoeuvres or a set of official manoeuvres for you to follow...


Mudry_CAP_10C_Flying 10.jpgMudry_CAP_10C_Flying 11.jpg


...   the throttle is clever as well with the normal centre push/pull knob style, but also a left pilot's grab handle style throttle as well. The sticks are very high (or long) for full minute control.


Sounds are all FMOD and all taken from the real aircraft on the ground and in flight for full authenticity, and they do sound pretty perfect and close to as real as you are going to get.


Get the settings wrong and you can look a bit like a dork in that the aircraft won't respond to your aerobatic whim's...


Mudry_CAP_10C_Flying 12.jpgMudry_CAP_10C_Flying 13.jpg


...    but study a bit and get the settings right and the CAP10C comes alive and you can then start to get the precision and manoeuvres you are aiming for.


Mudry_CAP_10C_Flying 14.jpgMudry_CAP_10C_Flying 15.jpg

Mudry_CAP_10C_Flying 16.jpgMudry_CAP_10C_Flying 17.jpg


Down the nose a bit to gather a bit of speed and then up and and into the loop...  you feel the freefall at the top and then down the other side and recover...   do that a few times and your head swells a bit to the fact that buzzing the tower on KLAL field feels like a good idea.


Mudry_CAP_10C_Flying 18.jpg


The headiness will go away quickly once you decide to land...  as it is the same as taking off in keeping your speed low in the low 70's Km/h range...


Mudry_CAP_10C_Flying 19.jpgMudry_CAP_10C_Flying 20.jpg


...  you tend to keep the nose high and almost at stall point, which doesn't help in the vision ahead on placing the aircraft correctly down on the runway.


Mudry_CAP_10C_Flying 21.jpgMudry_CAP_10C_Flying 22.jpg


You can place the 10C down and almost on the three wheels at the same time, but then it is hard to run off the speed and then slow down even from the low 60Km/h tochdown speed. Get it wrong and you with lose the aircraft as it starts to weave badly and even dig in a wingtip into the tarmac, and it took a few practise landings to get it all right and taxi back to the stand area in one piece...  it is really tricky to do and not for the faint-hearted as it is all too very easy to get it all too very wrong.



There are five aerobatic themed liveries and all are well done, two are very similar side on but with different layouts on the underside.

This CAP is not really a night flying machine and so the lighting is quite basic. The instrument panel however is really nice at night with some really nice effects and feel, the lovely annunciator panel is testable and looks great in the daytime or darkness.


Mudry_CAP_10C_Lighting 1.jpgMudry_CAP_10C_Lighting 2.jpg


Only difficulty though is the lighting manipulators centre panel. They are created for scrolling of the knobs and that works fine, but try to manipulate them manually and they are very hard to turn, and with a different manipulator for each knob...  tricky.


Mudry_CAP_10C_Lighting 3 LG.jpg


External lighting is very basic with one really large landing light that seems to be not adjusted.


Mudry_CAP_10C_Lighting 4.jpgMudry_CAP_10C_Lighting 5.jpg



For a great aerobatic aircraft you can't go past this gem of a CAP 10C. It comes with a lot of information from real aerobatic pilots to allow you to get the very best out of the aircraft in it's aerobatic roles, but it has a simple cross country role as well if you just want to fly point to point and not wanting to get yourself twisting around all over the sky.


Setting the aircraft up correctly for aerobatics is important, but you get a lot of help from everyone involved and the set up can be versatile as well, with one or two (a trainee?) pilots set in the aircraft. It is a very tricky aircraft to takeoff or land at slow speeds and in this area you will need a lot of skill, it is focused on and for a very capable pilot anyway. If you do have high aerobatic skills then you will get the very best out of the aircraft as it is focused on that aspect and tuned out for that area as well.


Modeling overall is very good and that lovely canopy is totally worthy of a VR headset alone, a few quirks are noticeable in still turning wheels, tricky manipulators and that oversized landing light are not really negatives.


Avia71 is a focused designer on these sort of aerobatic aircraft and again delivers a gem of a machine for that particular genre. There is a lot of professional input and testing to know you are getting the very best in that aerobatic delivery as well in realism, and that is what you are paying for in the end...  in the end only one thing sits mostly in my mind after reviewing this CAP 10C, and that is in god that you really want that Virtual Reality aspect for aircraft like this...  it would be absolutely mind blowing.
