RE: Extreme Flight 87" Yak 54 - Build & Fly
Bodyworks, I think that most people who have seen me fly the 87" Yak in person have seen the "Aneurysm" tumble. This is a very violent sequence of tumbles that will often get as many as 3 or 4 tail over nose tumbles before losing momentum. Believe me, the Yak tumbles like no other. Try these inputs: 1/2 throttle, straight and level, on 3D rates, simultaneously chop the throttle and push full down, full left aileron and full right rudder. HANG ON! Watch your speed.
The rudder on the Yak is extremely powerful. Save full deflection rudder for flat spins and tumbles and a slightly reduced rate for high alpha knife edge and snaps. This will make a huge difference in the stability of the plane in slow knife edges as well as making it far easier to stop snaps where you want them to.
