Sorry I had a typo,
I don't think a Saito 56 is going to pull it out of a hover very well.
I say do what you like.

Also if your gonna spend the money on the Saito56, poney up a few more dollars and by the 72. with the saito72 yo have more options for planes.

Its better to pay a little more upfront and have more power than needed. Then spend $170 and not have enough power then have to turn around and buy another motor.

I agree w/ Wayne on the 4 stroke thing. Its all what you get used to.

I had a YS63 on my topcap. Flew great. I was having motor problems and put on a ST45 w/ moosecan.. It still flew good. but it flew a lot better w/ the YS63 on front swinging a 14x4prop.

Some people like 2strokes, some like 4strokes. But is boils down to what you like.
