reincarnate
Using the choke to stop the engine will fray the reed valves, expensive, Also the Evo engines are a different make, made in Italy. Until you get your kill switch take out your throttle stop screw and use the throttle trim on the Tx to stop your engine, I use the trim in preference to a kill switch IMO its a bit like match boxes on a 50cc not rearly neccesary, if the battery dies on you in flight its because of lack of maintenence and not carrying out your pre flight properly. Now watch the fur fly.
