It would hover with the 46 but had little left.

Just because the engine is a .61 doesn't mean you have to fly around full throttle all day. I can hover at 1/4 throttle and pull out with ease.

It won't do that with a 46. It will hover at around 3/4 throttle and not much left.

Put the big engine on it. Power gets you out of trouble. My 2 cents.
