ruger, the carb barrel screw was locktited, not the carb hold down nut. For the control rates, elevator, ailerons are about 40 degrees, rudder is 45. I fly with a lot of expo on all surfaces, about 65 - 70%.

alfred, not sure why it would be flying tail down, you can try moving cg forward a bit though. I would take out the couple degrees upthrust that is built in. I agree with the knife edge, this plane does it very well, knife edge loops are pretty easy to do.
The plane will snap when it gets heavier, that is what crashed my old one when i was going too low/slow. Also there is that mid travel in the elevator where they will snap, however that is why the CAP's do some of the best snaps, spins etc. If i pull elevator full throw (40 degrees) right away, the plane just stands up on its tail, no wing drop.
