Here's the Boomer XL again... this is twice the size of the original and has just a few tweaks like more braking power etc. It also has a 4 blade prop like Mike Patey's STOL Scrappy.

I had released this earlier but took it down so that the OP could fix a small error.... I'm now reposting the AV.

Have fun and please check out the Scrappy inspired scheme I made for it as well!
