With out doubt, the saito 65 will fly it. However, whether or not you will be satisfied with it is uknown. I suspect if you prop it right you would be able to hover with it, but don't look for much of a climb out if any at all with it.
The .61 two stroke should do all you need it to if you aren't happy with the 65.
The plane is just a real joy to FLY, so if ya got the cash, BUY!!
