The plane in the following links would more than likely work well for it also. I am flying one with an MVVS 40 in it and it has significantly better than "Scale power" with that (IE - it will hover and pullout quite fast without needing to go to full throttle with that combo). I think the PTE 36 would also be adequate for it to fly "on the wing" - or "Scale" which is where many sport fliers fly.

The current crop of engines in this size range are actually quite close in power to the earleir "50cc" offerings that many of the earlier "50cc" planes were designed around.

As for the noise issue? others have already said it - buy an exhaust system that quietens it down or get over the fact it is noisy. Very few engines come with "supplied exhausts" that are actually quiet and even less manufacturers actually make alternative exhaust systems to the noisy ones. This is because of the modellers wanting to pay low prices for things - it is called a "trade-off".

Or the same plane from the Aussie agent (this may save the usual PM trail from the Aussies that occurs when I post links to US suppliers)
