I never had that prob. with my 88" EF Yak. You don't need a rearward CG with this plane to have an awesome 3D machine...perhaps experiment with moving it forward a touch. Sounds like your idle speed needs lowered some. Also, what pitch are you running? I used a Vess 23A and it acted like a brake on downlegs and landing. I agree, the EF Yak lands like a trainer and is one of the things that makes it such an awesome plane!
