THROTTLE RETURN SPRING!!!!! I use small hair bands from the drug store. I only care about failsafe on throttle servo. No need for external failsafe. 1 less thing to worry about...

The throttle return spring works because it is mechanical... Not "electrical" So no matter what your throttle will close. I dont even set my failsfe(I think its done automatically) because I use the return spring(band). But it doesnt hurt to have both...

ok...only thing if runaway will be freq clash, right? If rx pack low then the spring will pull the servo close too or before it low, we can feel the buggy cant full throttle already. Ok.....and Thanks.
