After playing around with layouts, it was time to actually start mounting motors and ESCs for real.
• Aimdroix extended aluminium arms
• T-Motor MN3110-15 780kV motors
• T-Motor S25A ESCs
• 4mm bullet connectors
MN3110 motor wires come 600mm long, which is a lot of dead weight if just cable tied up, so the wires are to be trimmed back.
Unlike the stock plastic arms, these aluminium arms will become a heat sink to help dissipate any motor heat, should that ever become an issue. Motors shouldn’t become “hot” in well designed system, however.
There were absolutely no issues with the outer sheath shrivelling back up with the heat from soldering, as often found with cheap and nasty wire.
With one arm done, only three more to go!
So how much weight was saved by trimming the motor leads?
Reclaimed 4mm bullet connectors can always be used elsewhere.
Next job: Soldering ESC leads to F450 lower board, and mounting the Wookong-M flight control components and receiver.
