Craft starts spazzing out on its own

for some reason the craft just starts to just spin and spazz around without any outside input, the Auto head on was deactivated

this seems to be really inconsistent as i extended the solar panels the craft starts to do this more violent but when they are fully extended this doesnt seem to happen anymore

and honestly i have no idea how to reproduce it, i have no idea whatever the hell is causing this. i guess it has something to do with the solar panels? i dont know
