G'day

I have had a few Saito 65s and I still have some Saito 62s in my collection of 14 or so Saitos. I would put a 13 x 6 on the 65 as a starting point or better a 13 x 5 if you can find one. The 5 pitch prop will give you plenty of pull while allowing the Cub to slow down for landing.

One of the down sides of having a slightly large engine is that you need a slightly large prop and it will still be producing quite a deal of thrust even with the engine near idle. This can cause floaty planes like the Cub to not want to land. A lower pitch prop gets round this problem.

The other "interesting" thing about Cubs is their tendency to suffer from "adverse yaw". You try to turn the plane to the right with the ailerons and it either goes straight on or it turns wide with its tail hanging down. The cure is to use rudder as well in the turn. If you have a computer radio, you can use a mix to add some aileron to rudder mixing which will help with this. It is best to make it switchable so you can turn it off. Otherwise, if you try to roll the plane, you will get a very nasty and untidy roll at best.

Have fun with your Cub and the Saito.
