Heh, if you're looking for a build video, Flite Test just released theirs, plans are out as well.
Didn't realize when I drew up the plans for this that Flite Test was doing the same thing. According to the plans, theirs has a wingspan of 20 inches while mine is 18 inches.
If you're going for rocket ship power, build the smaller one, but if you're looking for something more rounded I'd imagine Flite Test's version is easier to fly.
I've requested that the thread title be changed. Don't want to confuse this with the actual plane released by Flite Test.
