In your other post you asked about fuel economy between 2-stroke and 4-stroke. You'll get better "mileage" with a 4-stroke, although the bigger glow engines can be rather thirsty. If I were getting this plane, I'd look at a G-20 or G-26 gasoline engine. Not only does it use less gas than an equivalent glow engine uses fuel, gas is a lot cheaper as well. You could put a 16 oz tank in it with the G-20 and fly for thirty minutes. A 1.50 Saito would need at least 24 oz to run that long (and probably wouldn't run that long). The G-20 would give you more than enough power for a 12-13 pound plane with a wing that big.

As for hand starting, the EI gas engines only take a couple of flips, and about all you have to do with an electric starter is bump it once.
