Hey guys....I haven't run my 1.6 FX yet, but I have several smaller motors that I start by hand. TT46's, GP-42's an MVVS 45, and a 25FX. All of these little motors will start easily by hand when warm, and need only to be primed properly when cold.
I just attach the glow battery, set the throttle to about 1/3, and put my thumb and fore-finger in opposite screw holes on the spinner...(a little more difficult with aluminum spinner)..and then snap my fingers...the snapping motion spins the engine backwards until it hits compression, it fires, and starts running in the proper direction. I'm also pulling my hand back as I snap, keeping my delicate fingers away from the prop. I've got one engine w/ an aluminum spinner, and a Dubro with no screws...those are more difficult...If I can't get any of the engines to start in 2-4 flips, somethings up.
