(I know zilch about aerobatics)
I am not that far ahead of you. I've been advised to keep 25/2,500. It's kept pretty much there continuously (to maintain energy levels) but occasionaly reduced ie. spin entry or to reduce torque/prop drag effects.
Without proper instrumentation it all seems abit hit and miss. When the article talks about maintaining speed and then only gradually increasing this is fine if been holding a constant Vy/ cruise climb. But if your speed varied in the last 2 minutes between (in the case of the plane I am presently flying) 50kts and 175kts which speed should I be using as a base line?
Any way many thanks for your help and Happy New Year.
