AirTech...

Yeah, I'm using the EVO45 in my Cap. It's plenty of engine for the CAP. I like it. I've also built another plane with the DA50. The DA will pull one size bigger prop so it clearly makes more power. But the EVO is plenty for the CAP because that combo is so light.

I installed one rudder servo only (HS5945) in the tail section. It has plenty of torque for any maneuver and you don't need two servos. My CG was made with only movement of the battery. Everything is pretty much centered in the cabin area. No problems with the CG at all.

I really like the way the CAP flies. I'm going to add a little bit of up thrust to make it easier to hover and better on the uplines because mine pulls pretty bad to the wheels. Other than that I love the thing. It will do outstanding waterfalls and flat spins and snaps, and KE and tumbles and etc. The only bad habit is the pulling to the wheels. I think a small amount of upthrust will correct that.

thanks
