Nothing important to add to this discussion but I do want to say I have the Turnigy 2836 1000KV motor using a 9x6 folding prop on my Phoenix Evolution (flying with the short wings) and that motor has been working superb. Also the 9x6 folding propeller (from Hobbyking) has not come off once from the 4m diameter shaft on the 2836 motor. What a great combination those two are. I'm really thinking of trying the other 2836 with a slightly higher KV rating and see how that does. And after this motor with the 4m diameter shaft I really don't want to use any motor with a smaller diameter shaft.
