These cheap foamies are great fun. Friends and I have been installing r/c in these things for several seasons now. We've used both the straight-winged Ultra Flyer and the swept-wing "airliner" types. Also we've modded some including a flying wing made from the swept-wing variety. All have flown well. Yours seems to have had plenty of power and flies nicely also! Check out my foamie vids!
@RICHYZEE1 If I am right it was a motor and esc I got on ebay was a Tower Pro 2408-21T and a 15 or 20 amp esc. The prop I just threw one I had laying around from my stryker which was a 6x4 which probably wasn't the best but since I mounted it on top so that when it landed the prop couldn't stick. This version prob weighted a pound since it had a 3cell 2200 battery up front to keep the nose down but provided a good 15-20 minutes of flying when it got high enough.
