Motor coupler

[NorthernWaters]

Hey gang, I was wondering what size of a motor coupler I would need for a PB 1800kv BL motor and the stock flex shaft that is currently in my MG.. I took the 1500kv motor out of my MG and had my son install it in his Impulse 26..... He really likes the extra speed

Should still be the same as the one on your old 1500 motor,, 5mm on one side for motor and .150 on the other side for the flex!!

Thanks HJ...... I'll have to order one or two up.
