We cut the right cheek cowl and mounted the engine sideways. - No linkage hastle and the exhaust goes mostly under the plane.

Install a larger fuel tank, build a larger rudder, etc. (from the threads on SE) and go hover below half throttle. If you don't then get set for short runs (thirsty engine), no sustained knife edge or unlimited hover. It's not hard to do and worth the rewards. By the way hang a 13 x 6 prop on it. At the low rates it's as gentle as a trainer and on high rates with the CG moved a bit aft as Unstable Boy stated, it's pure adrenaline. It can do it all at such low speeds and so tight on the deck (if your nerves are good) that it seems to defy gravity.

P.S Unstable Boy Try a flight with the big .72 and you might change your mind; we tried both...
