Plastic screwdrivers for adjusting gyros and speed controls do not exist because of cost.
They are to prevent the servos from twitching from interference when the two metals meet. I personally would not want my throttle servo dancing around when I'm trying to adjust the gyro. I have also seen recommendations to use plastic when adjustting your low speed carb needle too.
Umm... exactly what "interference" would this be???
A plastic screwdriver would strip out before it even budged my low speed needle!
