Should I just stick with the recommended .46? I'm a newbie currently learning on a Superstar 40, picked this up to get flying in a few months as skill progresses. I live @ 5000 feet and will surely do more zooming around the sky before I progress into 3D. I've heard issues w/ the tailfeathers at too high a speed? I'd like enough punch to hover and power out at this altitude, but also not go too fast for the plane. Prop/ motor suggestions?
Also are any fuse or other reinforcements suggested for a hard landing newbie? Stuff looks spindly in the fuse.
Thanks

and that might lead to overspeed in my case, blowing the elevator off? they're pretty explicit in the manual about not overdoing it.

10 4 there.
In cars, motorcycles, etc I have a digital throttle (all or nothing) but don't keep it pinned in the planes.
Thanks!

the most popular engine for this plane is the saito .72 (great engine for it, that is what I'm running also) run it with a 14x6 or 15x4 prop and you shouldn't overspeed it. no matter what, don't go with a .46 2 stroke in this plane, especially at your altitude, you won't be getting everything the plane was designed for.

I have a Saito 91 in mine. I'm closer to sea level, but it's a blast with throttle management. I only use full throttle when it's pointing straight up. Don't worry about it being nose-heavy. These all come out tail heavy. Mine is at the back of the recommended CG range with the battery at the front of the RC compartment. You may have to put the battery above or below the fuel tank. As far as 2-stroke, I would go with at least an O.S. 50. If you can afford it, go with 4-stroke Saito 72, Saito 91, or YS 63. OS is same performance but a little heavier. The YS with pump would be nice on this plane due to the inverted engine. Non-pumped engines flood easily because the tank is higher than the carb. Do a search on regulators, too. I'm thinking of getting one to help with the flooding problem I have when it's on the ground. I don't seem to have a problem once the engine is running though.

thought I'd dig this back up and add some results. I put a Magnum 61 2 stroke on it, and it will barely hover at full throttle. I wish we had some air up here, looks like it's gonna have to be an mvvs 90 2 stroke to gimme some punch. Oh I'm running an APC 13x4W prop at 10000 rpm, still experimenting with smaller props.
