My first crash also taught me that my motor needed to be more secure in the event of a prang so I measured the gap between the 1527's aluminium (boat) rear support mount and the c/f side plate on the battery tray and made a spacer to suit and bolted it up, no more side movement!...
The aluminium cooling can on the motor is a water cooling can made for the motor, I cut and drilled to allow the air to be caught in the spaces and hopefully help cool the motor(I don't need any of this for 6s, it's just incase I decided to unleash 8s at some stage in the future). I applied thermal paste in the small gap where the water would normally be for heat transfer, gotta be better than nothing and it'll be a while before this motor see's any heat.
