As seen here all i have to do to get it going is move it a tiny bit, i tried making move a little higher that dosent work it only works when i do it, the wheel friction is 0, i tried making it go to 1 then 0 which sometimes work but i need it to work 100% of the time
The aircraft is real sized at 1:10 scale so really tiny
What sort of technique are you using to simulate the airplane? If you’re using mover constraints (VectorForce, LineForce, etc.) then possibly the force on the assembly is too low and it can’t break out of physics sleep.
You might be able to test to see if this is your issue by disabling “Allow Sleep” under the menu found by going to File → Studio Settings → Physics. Or, under the same menu, you can toggle on “Are Awake Parts Highlighted”.
