I spent a few hours this afternoon installing the HXT outrunner motor. It was a bit larger than the MY1016 that I had previously had as a prototype. And as it is an outrunner, this necessitated a different type of engine mounting.
Here you can see the base end of the outrunner motor with the power leads on the left. The X shaped bracket came with the outrunner and is what I used to attach it firmly to my Boxer's left engine support bracket.
