Is anyone using any kind of remote switch to kill the engine from the transmitter, and does anyone recomend this?

My remote kill for the engine is full idle and minimum trim. IMO if a remote sw is installed independent of the throttle control there is a possibility that it will inadvertently activated with disastrous results specially when flying inverted and close to terra firma.

My thoughts exactly.

Thanks much, no remote for me!

Good call. Just make sure your throttle trim can kill the engine and you're all set.

This test is highly recommended step in a good preflight cklist.
