To Earl Williams,
Earl, are you using the 2" alumimum spinner as the size specified? If so are you able to cut the prop holes for your APC 15x4wide in such a small spinner? What brand spinner are you using?

Also how did you deal with the specified servo reversing for one of the elevator servos? What part did you use or did you modify to avoid this?

Are you using a pump with your Saito?

I agree with you that set up correctly over powering is not a bad thing. I am flying a 6 pound Sportster with a Saito .91 and it just feels right.
