To mount the motor, pop the forward spar and mark it with an asterisk to make sure that it goes back on the same way and all the screws line up. Then at centre I've countersunk a recess for the back end of the drive-shaft (which protrudes for reasons best known to T-motor), along with a couple of 2mm holes at 30mm apart.
Note the spacers on the bolts to prevent them piercing the windings if possible... tho' they did anyway, because the U7's a fairly shit design.
