Reasons for a fiber optic kill switch

1 My most important reason if I loose power to my plane at full throttle I don't want to watch my plane fly into a crowd and hurt or even kill someone. Some would say leave the spring in place would solve the problem but the spring wouldn't return in the event of a jammed servo.

2 Last flight of the day servo fails at 1/4 throttle battery runs out before fuel. Sorry but a fast landing nose in to hit the prop is way to risky for the average flyer. Potential for plane damage high.

3 Firewall comes loose changing linkage length throttle stuck. I don't want to fly around with loose engine till engine dies or risk plane on high speed landing

4 In case off throttle failure with kill switch I decide when to kill the motor leaving me in a good position for dead stick landing. This allows a good potential for your average flyer to bring his plane in safely

I have seen all and or read about all of the above scenarios. I have never had to use my fiber optic kill switch but for 60 bucks I think its cheap insurance. You may build the best plane , linkage, firewall whatever but you don't have any control over a receiver, battery, switch, servo failure. Pat no offense I have read many of your posts and regard you as a professional builder flyer and generally appreciate and agree with your posts but must disagree with your stand on this topic
