Inverted stall/spin problem

Deano87 · May 28, 2019

i still keep trying inverted stall in ww2 warbirds in dcs Yak-52FM behavior which you presented on short clip looks very wierd for aerobatic plane which should do inverted stall on daily basis not once in the life time
i not sure if i am staling airplane becouse speed is quite big and AOA is very low i think that problem is that i can't increase aoa below certain speed and the plane start diving keeping speed up but i cat enter any spin or wing drop in this situation full rudder dont do much beside increasing side slip
i tried extending flaps wich in normal flight drag nose down in p-51 but while flying inverted flaps did oposite thing nose of the plane imidietly dive even harder flpas did exactly oposite thing that in normal level flight
maby the plane is stalling but in very stable manner

Why are you trying with the ww2 planes? They don’t exhibit this bug. You are wasting your time.

Just a note from manual:

So maybe the reducing RPM is essential. IMO you can not judge the FM when noone of us did fly this machine IRL. And because all other aircrafts do..... Mind this is Jakolev Jak-52 and not the Zlín Z-50. So, only the real Jak-52 pilot konws. Not the chairforce pilots.

This happened to me last night. Couldn't recover, though I had plenty of altitude. Tried everything. Reducing engine RPM, rudder pedals to neutral, pulling on stick... didn't work.

Then tried opposite rudder, didn't work.

"Popping" it with brisk stick movement. Nada.

FULL power. Nope.

Aileron deflection in either direction? No joy.

2500 meter fall...ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh--kersplat!
