ever get that feeling when you build a plane it's going to give you trouble? scratch built a 1/4 scale chimpmunk 108 inches,had that feeling. flew fine for 2 months then smashed itself in a very imbarising way at a public day. stripped it down found blackwire in the new battery wires. rebult flew fine for 4 months, engine richened up on takeoff had to make the circuit nealy madeit stalled BIG mess.rebuilt it third time maybe lucky this time.oh i wish that feeling would just go away.
