He has changed a lot of the code quite drastically in the different versions, physics models, key inputs etc so there are huge differences in how the vehicles will react in the different version sadly. I only use 1.1.2 so all my vehicles are tuned to work as well as I can make them work in the current version. Sorry I can't help you.

i have problems with severe shaking in a lot of the aircraft youve made

i have a question
why do planes not work correctly in experimental or legacy

No they don't work in Legay or properly in the new beta, sorry.

it doesnt work in legacy sadly

Hopefully I fixed the possible shaking by avoiding the landing gear actuator to go into the wing as much.

its fine lol

Sorry buddy. :/

when you find out these are the regular version of brick rigs and your pc is to laggy for 1.0 and you play on legacy :(

Please let me know it you are having trouble with severe shaking and I will remove the foldable wings.

I may have to remove the foldable wings since the wheels clipping into another moving part can make it go shaky shaky all over sadly.

NOTE! Be very careful with the brakes when you land! Just tap the break button ever so gently until you get below 80-ish kph.

Weirdly enough (I know you want to test it!!!) it still flies reasonably well if you fold the wings mid-flight. :D
Just remember to go out of Alt- mode to fold them.

Seems like if the rear wheel is filled with more than 80% air the plane starts spinning on the ground. At 80% it barely happens. Hopefully. This game is WEIRD sometimes. :D

BTW if anyone knows why the plane spins while on the spot when spawned in please feel free to let me know of any solution. The rear wheel spins although it is NOT driven and it's quite annoying it won't just stay in place. :/

Version with bombs and rockets coming soon. :)
