Well I decided to try to remove the flaps on this I figure I never use them at all these UMX come for landings really,really slow enough and also I decided to extend the Ailerons in inches to help out a whole lot better in performing rolling circles and also heps out a little bit in hovers to help keep the wing from rolling but not much just a bit. Now you aren't going to see the full Ailerons physically moving but you will notice it in actual flight I did this mod in 2 other UMX Av's I'll be posting tonight so stay tune. Enjoy!
