If I were to have the throttle servo/linkage fail, I have the choice where/when to kill the engine so a controlled landing can be made with no damage to the airframe or the prop for that matter.
This is another good argument for having a redundant system.
Maybe it's just me but in over 25 yrs of flying I've never had a throttle linkage fail. I fail to see how this redundant kill switch question became such an issue. Do we all need a redundant right aileron in case that particular one fails or is it best to build and install every control properly so there is no reasonable chance of it failing. No national RC organization has seen fit to make this kill switch mandatory so what's all the fuss about. Each person decide for themselves and that's the end of it.
