I spoke with John Gibson today about some practicing he and Jim Katz were doing over the weekend. During some previous testing with the 428 model we noticed the flight pack switch becoming more difficult to turn on and off. John said Jim’s switch would not turn off only about 6 flights on his 424. I assume his switch is mounted like I do perpendicular to the crankshaft plane across the fuselage with a small wire protruding out the fuselage size.

These were stock Futaba switches mounted firmly on light plywood platforms. Any of you guys experienced this issue? May be a cause of loss of control on some of our racers. Has anyone addressed this problem before?
