I guess I could hook up a choke servo plus I could use the throttle cut on the transmitter, so I guess there is no need for an Opti Kill. No need for a powerbox. The one thing I have got to hate the most about flying is charging batteries. But if it can be done in 15 minutes then I am all for it. Does anyone know of a wiring schematic that shows how to wire the battery to the servos and reciever seperately. If I can get 6-8 flights from one battery then I could use two and fly all day, right? Is there a build thread on here anywhere showing someone going into detail about how they setup their 30%. I can't seem to find one.
