Thank you for the info! I can't believe this response is almost a year late. I dipped out of the RC hobby for a while, as it's more of a casual hobby for me. I actually ended up finding a plane by WLToys that actually fit all of the criteria I was looking for. It's made of EPP foam, charges a 3.7v battery from the transmitter or USB charger, and it's 3 channel. I never looked at the size in the specs, but looks about to be around the same scale as the Champ RTF.

I think the Champ is a super fun plane, but it's tough sometimes to have this hobby where I live, as you can have a perfectly still day, and the wind decides to gust like crazy once you get the plane in the air. And the traditional foam just doesn't cut it for me. This EPP stuff looks like it's almost indestructible!

Anyway, I'll post again to let people know if I like the WLToys F949. They also make a 4 channel version, the F939, and a 3CH glider model, the F959. They seem to be a great brand, as I have the V911 helicopter which has withstood tons of crashes without any damage.
