Ok. Now I'm looking for a good kill switch. Engine is an Evolution 26GT. I want an optical, but don't know where to acquire one. Currently flying another Evo 26, and a Fuji 50EI, and need one (well three actually[8D]) that works with these engines. Get ready to stone me, because I'm currently using the choke at low idle to shut down. I looked at Smart-Fly http://www.smart-fly.com/Products/Ignition/ignition.htm but seems kind of pricey. If I'm wrong then tell me please, because I have no point of reference. Just hate to bend a rod by shutting my engine off wrong.
