RE: Fiber Optic Kill Switch ????
Rod and Chris,
I am using one in my 35% RadioCraft with ZERO issues. The older versions had some problems but if its a newer unit you'll be fine.
Soft mount it over some foam.
I use mine on Aux 4 (rotary knob) and leave it activated all the time. I then just use my Ign switch as normal. I will occasionally shut the motor down that way just to check it.
Well over 200 flights with it and no problems.
Its a smart thing that have IMO.
