Just wondering about what 2 stroke engine size a prop combo would be good for this plane to have ample power to hover and what not, I've been hovering around an E-flite pofile Edge540 electric plane for a couple of years now and not sure if a OS .46Fx would be enough or not, for pulling out of a hover adequately.
Also some of the other engines I have on hand:

YS 45 side exhaust
rossi 45 and 53

Thanks

The 2-stroke of choice is 55AX but the 46 will be fine. You can always get a little more out of it with a mousse can pipe or Macs one-piece muffler.

I have a Jett muffler on it right now in my Quickie 500.

I have used both motors on that plane, 55AX is really the way to go. The 46AX will do the job, but if you are learning 3D the 55AX will get you out of hairier situations. With the 55AX you can run the APC 13x4 with no problem, throttle response will be good and pull out power will be good also. But I think one of the biggest advantages with the 13x4 is that, you have a larger area of airflow since you have a larger diameter prop. The more air hitting those flight controls the better. Ive got a Saito 82 on the OMP pro yak with a 14 diameter prop and it feels alot more responsive to my inputs because Ive got so much air hitting the surfaces.
