I can vouch for the Alpha COMBO ... I've flown mine for about a month now with no real problems... Changed the glow plug, and after a small "misunderstanding" with the ground (see below), the prop....

1 piece of advice... GLUE THEM D@#* WINGS TOGETHER!!!

As stated above by botlerocketwar, I think my days as a car racer are numbered... My car stuff has less & less bench space every week....

Good luck!!
