Just picked up a Futaba GY401 gyro for my CPP. I'll install it tonight and set it up with the 9Z Tx. We'll see how different it flies. Another thing I'm going to do is put Dean's 2 pin micro connectors on the CPP and the E Flite batteries. That way I can use my plane lipo packs, doubling (to a total of 4)the number of flight packs I have.
