Nothing. I just need to finish my two model projects made of foam boards I bought from Walmart store. First model is Kendin Yap’s video on the internet and a race wing I designed my self. Then I’ll buy the materials and try it out. I need to paint it then add all the other RC stuffs. It weighs under two ibs. Now. 3S LiPo battery, 1000 mah, ESC 30 A Brushless motor and the RC with receiver and a servo. And a propeller to go with the brushless motor. Two wheels up front with the center of gravity and a trailing edge. I hope it flies.
