I have the permatex green, didn't realize it was medium penetrating. I will probably stick with epoxy then. Only place I know that carries loctite brand would be online retailers.

The conversion from Wye to Delta is 1.7 winds, so a 10 turn Delta is equivalent to a 10/1.7 turn Wye - almost 6 turns. This keeps kv constant. The conversion from a 10 turn D at 980kv to a 6 turn Y is as follows: [10T/1.7=5.88T] [980kv x (5.88T/6T)] = 961kv with a 6T Y termination. Substituting the 6 for any other wind count will give kv with Y termination.

Looks like the 3032 with a 6Y on 4s lipo will be pushing it pretty hard. 15k rpm, don't know how well the ring bearing will take it.

One thing I didn't think of for startup is the length of wire and the inductance on a coil. The ESC will sense a higher strand count coil better, so maybe this could cause lower kv motors to start up better. Not a product of motor torque as much as the ESCs increased ability to see a higher wind motors position? The issue with total motor power always gets me when thinking of startup. To me any 1000watt motor should start up the same unless the wind count is on the extreme end of things. Probably not the most accurate assumption.
