As far as I can tell, Krzysztof Kaniewski's Piper PA-11 Cub Special is currently the only high wing bush (sorta) plane available for Aerofly FS 4. It is definitely a low and slow aircraft suitable for sightseeing. Note that the airspeed indicator is for MPH and not knots. It is fairly complete although it does not seem to have a functional fuel mixture control but since the FS 4 simulation engine does not use this in calculating engine power output, it's not important. The radio does not work, but that is not required for Aerofly FS 4. You can manually start the engine by using the mouse right button to spin the propeller or you can to assign a shortcut key for "Engine start", requires magnetos on and fuel on, there is no master or battery switch. The "Cold and Dark" and "Right Before Engine Start" tmd presets do not work in that the engine will be running regardless. It is sorta a bush plane but does not have flaps so short field operations may not work out. It does have large tires although not tundra tires. Also, since it only has a 65 hp engine it will have a very slow climb rate at high altitudes (like at Grand Canyon National Park Airport)
You can download it from Krzyszstof Kaniewski's Github repository by clicking on the green "Code" button and select "Download Zip". Once you have extracted the inner pipercub-master folder and put it in your aircraft folder make sure to rename it to just pipercub.
Another possibility is that since you changed to position of the wheels, one of the previously defined collision boxes (fuselage or landing gear) now intersects with or is below the tarmac so a collision condition is reported and needs adjustment.
One possibility, If you configure the view for a tail chase camera, then force aircraft reload using assigned shortcut key and you see that your aircraft spawns above the runway then drops onto it and the sim restart due to aircraft "crash" condition then maybe your right/left/tail gear Kp and Kd settings are too low.
Note: You probably already know this but just in case.

A handy freeware/shareware utility to use when you want to get angles and dimensions/position data for use in your aircraft model from line drawings or pictures that you have is a program called MB-Ruler "MB-Ruler helps you to measure distances and angles on the screen and distances on a map."
For Aerofly FS 2/4 aircraft model creation this is somewhat more critical than for X-Plane 11 because while in X-Plane you can simply define a wing dimensions, chord, and dihedral for the wings, in Aerofly FS you must specify each specific x,y,z "Station" coordinates to define the wings geometric form from which it derives the chord, dihedral, span, etc.
There is a parameter in the c172.tmd file that I would consider equivalent to a trim tab setting. In the c172.tmd file you will find the following servo definitions for the Aileron and Rudder servo controls.
<[servoclassic][YokeAileron][]
<[string8][Input][AileronTrimmed.Output]>
<[float64][Speed][12.0]>
<[float64][P0][0.0]>
<[float64][P1][1.0]>
<[float64][Position][0.0]>
>
<[servoclassic][ServoRudder][]
<[string8][Input][RudderTrimmed.Output]>
<[float64][Speed][3.0]>
<[float64][P0][0.0]>
<[float64][P1][-0.524]>
<[float64][P2][0.0]>
<[float64][P3][0.0]>
>
The P0 term is a constant that is added to the controller output from your joystick or rudder pedals that is equivalent to a trim tab setting. P1 term is a multiplier constant that the controller output is multiplied by. Currently P0 set to 0.0. I believe the valid range is a floating point number between -1.0 and 1.0, obviously you would start small like maybe 0.1 plus or minus because if you use 1.0 or -1.0 you have swamped out the controller output with the highest possible value since its range is limited to -1.0 to +1.0.
Save a copy of your original c172.tmd first, then try different values for the aileron and see if you can zero out the roll rate at your preferred standard cruise speed and altitude, at say 5000 feet altitude for a c172. Not sure if altitude matters, it does if air density is modeled, but since temperature is not user specifiable I kind of doubt it.
Well since most of the posts I made are not about helicopter development, in fact only the first few posts in this thread seem to have been that, I wonder if it would have been better to just change the thread title to something more along the lines of "How Can I Create an Aerofly FS 4 Aircraft Model?"
Simple solution is to assign keyboard shortcuts for aileron trim and rudder trim. You can then use these to zero out the roll tendency even if the real life aircraft does not have these particular trim controls, as most will only have an elevator trim control wheel. I gather most people like to have to use continuous inputs for aileron and rudder for realism though. In my case I mentally acknowledge this but since I am using an X-Box controller rather than a flight yoke and rudder pedals having to does this is somewhat fatiguing and imprecise.
A more complex solution is to use a text editor like notepad++ to edit the aircraft c172.tmd file to adjust propwash percentage and rotation for the the aerowing objects (left wing, right wing, left horizontal stabilizer, right horizontal stabilizer, vertical stabilizer) by trial and error. That is to say first adjust propwash percentage and rotation then test fly then adjust ...etc until satisfied.
Here is the relevant wiki link for the tmd.aerowing object that explains propwash parameters

Since this has become an explanation thread on how to create your own aircraft model for Aerofly FS it seems worth mentioning that if for some reason you cannot find the airfoil Cl, Cd, Cm polar plots for an airfoil that your airplane uses at airfoiltools.com then as long as the aircraft is subsonic you can use a free program called XFOIL to generate this information in order to create the tmd.airfoil object for your aircraft's wings.
Here are some info links for getting and using XFOIL

Also, while not necessary, it may be useful to use a utility program that is included in the free demo version of X-Plane 11 called Airfoil Maker to help visualize this data graphically.

Here is an example of what Airfoil Maker would look like using as an example the NACA 2213 airfoil from the X-Plane 11 freeware version of the Spitfire by DomHenry (source: https://forums.x-plane.org/index.php?/fil…ne-spitfire-mk1 )
Handy link for finding out what airfoil a particular aircraft uses:
If you don't have any other flight simulator then you probably don't know what the free Little NavMap program is. Aerofly FS 1 & 2 & 4 are probably the only flight sims that don't have a network interface that would allow Little NavMap to work with it and that is due to IPACS not Little NavMap. Little NavMap can work with FSX, MSFS 2020, X-Plane 10, X-Plane 11, X-Plane 12, Prepar3D but not Aerofly FS. It really is a shame.

If you have any of the other flight sims that runs on a desktop computer (Windows/Linux/macOS) and have never used little navmap than you can get it here, its free:
Would also be nice if Aerofly FS networks interface supported both data in as well as data out with a public interface document that would allow Little NavMap to operate with it like it does for FSX as the screenshots below show.
FSX Steam Edition + CumulusX! freeware with FSX default DG 808S single seat glider. Little NavMap flight track (Started Perris Valley Airport).
CumulusX! thermal configuration used for blue sky thermals.
Found a thermal, now round and round I go!
And well... you get the idea. Who knows, if this had been Aerofly FS 4 with VR, one could end up tossing all their cookies.

UPDATE 9/24/2018 Please see the comments section and gplv3 post and new acf file for the Firestar II contained within post. Here are notes from post by gplv3:…
These are all the Aerofly FS 2 wiki pages I could find for aircraft model development information. I could find no wiki documentation for tmd.engine, tmd.GPS, tmd.graphics, tmd.camera, tmd.sound and other a many other things you will see in a typical tmd file.
aenbacka I would probably forget about doing anything that has any kind of GPS instrument in the panel. You can look at some of the code snippets from G430 and G530 enabled aircraft tmd files for yourself and if you can make heads or tails of it without any documentation on the tmd.GPS class in Aerofly FS 2 then go luck to you.
