Motors beat engines!
Static thrust of at least 1/2 of weight would have to be the bare minimum for decent sport perf, (assuming proper pitch speed of course), but planes get a lot more fun when you hit the 3/4 of weight mark or greater. True vertical requires thrust greater than weight as the load is weight + aero drag in oz's is total load.

Hit about 1.25 times weight and vertical becomes quite impressive.
