Are the flaps repaired? I mean - how the Aerodynamical centre was pushed forward (default of the engine) instead of being pushed backwards, so that you went into unwanted cobra on every takeoff?
this plane don't need stick or trim for takeoff, only flaps, just wait that it leave ground
after takeoff adjust your angle and retire flaps
Yeah, but that definitelly is not right behavior - even without touching the stick, the plane out of blue "jumps" it's nose up, not much, but it does so. From all what I've seen on YT, the takeoff is always very smooth and then pilots pul it up into 30 deg climb - with flaps as they were, with this mod you'd fall into flat spin and you'd not know how you ended up there... Plus it is quite dangerous when landing.
So that is why I think it is worth solving...
