I Wish Manufacturers Wouldn't Do This, Part 6 . . .


Some kits include an engine hook that gets get bent out of shape after the first flight!  
Use SPRING STEEL, not pot metal. 
You can get spring steel engine hooks from BMS. (Balsa Machining Service)

  1. I remember first encountering this problem on a kit from Quest. The situation was made worse because so little of the engine hook could be flexed when inserting the engine. Just trying to fit an engine would bend the engine hook far enough that it wouldn't spring back enough for the rear of the hook to engage the engine casing -- meaning you'd need to use a tape wrap over the engine hook and around the engine mount tube and the engine (making the engine hook somewhat pointless).
