Dar;
I think you are the only one who got it!!! Saito's are good motors. You cant go wrong.

flatspin;
Both my 63's and my 53 turns in the mid 11's. The 63's fly well on the 14x4w but the lower end spool up is much better on the 13x4w. I was using the 13x4w on my 53 but have since gone to the 12.25x3.75. My little 53 has been the bomb. Takes a lickin and keeps on tickin. It s on plane 7.
