It's true - old threads don't die! This one is back (briefly, probably!) from hibernation.
I was inspired by this thread to try to scratch-build a classic air racer. Initial test flights went well, but for some reason once I'd "finished" it it was a mess. Lots of crashes later (and after a few breaks from the problem to get my motivation back!) I have finally got it sorted. Somehow the CG had shifted rearwards during finishing (surely paint wouldn't be enough to do that?) and having found room to shift the battery forwards it's now a nice stable scale flyer. Picture below taken after flying two batteries through it yesterday - I will now finally finish the plans, and maybe even build a new fuselage as this one is looking a bit "tired".
Better late than never?
