MY X250 was a great flying plane. A dysfunctional Max 500mAh NiMh is responsible for stall shortly after take off that demolished the nose and pulverized the brushed power system. The carcus hung in the rafters of the hanger for many years until a visitor didn't understand why I keep what looked like junk. Well I said it's mostly dead not completely dead. He didn't believe me....I wanted to upgrade the frame any how with a steerable nose wheel, 2 aileron servos, and Lipo BL power system. The nice thing about a project like this is... instruction? we don't need no stinkin instructions!
