I'm pretty new to airplanes. I've already have about 20 flights under my belt with my old Verus trainer which I let get to far out and lost it. I had a HB .40 PDP on it and it flew great and had quite a bit of power. I'm now getting a SkyRaider mach 1 as everyone in my area has said it's the trainer to get with it's semi symmetrical wing and the constant winds we get here in Kansas. I've seen a lot of people running 4 strokes and I just love the sound of them and their low speed torque so I decided to pick up a ASP FS52AR motor. From what little I can gather it looks to be a fairly good fit to a .40 sized trainer be it maybe a tad under powdered which I'm thinking might be a good thing. I don't need speed just something less messy and more fuel efficient.

I'm asking for any advise you guys can give me. Prop size I'm unsure about. I was running a 10x6 with the HB and was thinking a 11x7 APC would probably be the ticket. I think it's recommended to break-in with a 11x5 and I plan to run 3-5 tanks through it on the bench for break in. I'm pretty sure the FS61AR sleeve and piston drop right in and something I'm thinking I might do in the future if it's too under powered. Any advise is welcome and I'm just making sure I'm not crazy or something. I'm thinking if I like it enough I'll pick up the FS91AR for my super stick which is my next plane that I plan to set up too in the future. I got into it a little to soon and had a very hard landing that broke the wing. I'm working on repairing it currently and put a stronger motor on it. It was running a Super Tiger 40 that just didn't seem to have enough power for it. Several of the fliers at my park have switched their entire fleet to four strokes and they all said it's amazing and they will never go back to a 2 stroke.
