I got the Main Structure assembled this morning and mounted the Vertical M100 motor on the Horizontal Motor Mount and Horizontal M100 motors on the Vertical Motor Mount structure. The pictures below show how clean the motor conversion came out:
Front View showing the rears of the M100 Horizontal motors and a front view of the M100 Vertical motor, motor mount, and propeller.
Rear view showing the Horizontal thrusters' propellers and a rear view of the M100 Vertical motor, motor mount, and propeller.
Top View showing the top of Vertical motor propeller
Bottom view showing the two M100 Horizontal motors and propellers and the bottom of the Vertical M100 motor mount.
The M100 motors have three exposed solder pads for the motor phase windings so I plan to use leftover 22 gauge wire to provide the connections from the pads to the their respective ESC wires in the wire harness. I will then pot the exposed solder pads with epoxy to waterproof them.
The M100 motors weigh 225 grams more than the original DST-700 motors so the stern of the Frame is going to try to roll back about the center of mass. Hopefully using bigger fishing sinkers might compensate for the increased weight, however I may have to add some buoyancy to maintain close to neutral buoyancy. Only testing in my test tank will tell.
More to come.
