[b]You got it right steener, You have to spin and start the engine CCW, I think every internal combustion model airplane is designed and timed to run CCW. Otherwize you would have to use a pusher prop. If you have the fox spinner nut that comes with the deluxe 4D you should use a nice piece of 5/32 X about 8" music wire to tighten the nut. And be careful the engine doesn't get too much fuel in it causing liquid lock, (flooding) you can bend a con rod if you use a strong starter. Take out the glow plug and clean it out first.
