The only thing I worry about is the throttle curve on the small gas DLE's. Starts off very shallow, like a 2-stroke glow engine. On the other hand, the bigger engine, or the electric motor for that matter, swinging the bigger prop, will give you a much more consistent thrust to throttle curve.
The other problem is that a 20x10 prop at 2440W will pull about 17.5 pounds and an 18x10 prop at 2440W will pull only 16.5 pounds even though the RPMs are higher. So although the power-to-power ratio is even, the thrust ratio will be disappointing at most throttle setting until you get up around WOT.
