I devote the next three posts to T-motor's U7 V2 that I'm using here, and which can best be described as 'useless'.
Blow the pic up and you'll see how the bolt-holes perfectly align with that black wire which powers the motor, to the extent that you short-circuit it should those bolts go just a little too far. Had they pitched holes at 35mm instead of 30mm you'd be home clear, but where's the fun in that?
This incidentally is the improved 'V2' version of the motor... those with the V1 version are advised to slit their wrists at this stage.
