Also a change in plans around the motor placement. Going to do a test with them mounted at the rear of the kayak instead of the pontoons. If it allows for differential steering at the rear it will make for a more flexible cleaner setup.
Working on the hardwired Arduino controller setup next…
Posted this in another thread but some updates…
Plan now to mount the T200 at the rear of the kayak as opposed to on the pontoons, makes for a simpler cleaner setup. Hopefully can get enough separation of the 2 T200 to still allow for skid steering. Motors will be mounted on an inverted PVC Y off the rear rod mount.
I played a lot with trying to increase my watercraft’s speed. At one point I was putting out 4 HP (and melting solder connections) with my non-Blue Robotics experiments. I then discovered https://en.wikipedia.org/wiki/Hull_speed and realized no amount of power would let my boat go faster than 4 knots.
The T200’s put me in that 4 knot range and I haven’t done the detailed testing to see if I can programatically back off on the throttle if I’m wasting any power.
Quick video of the setup:
Hey there, wanted to see how the progress was coming along and if you have been able to test out the Drill batteries on the water.
Unfortunately, my father had a stroke this spring which basically sidelined the project. We are hoping to test it this spring when weather warms up now that he is recovering.
We look forward to see you soon. 
I’m planning a similar outrigger project with T200s. This is my first project and I have more questions than contribution at this point but excited to learn from the groups experience to jumpstart progress.
Two topics I’d love to get the group’s input on:
I. T200 Placement - How’s control with the skid-steering? My primary application of this project is fishing, where maneuverability is at a premium. Does rear placement improve performance? My initial thinking was mounting under the outriggers to move the pivot point closer to the center of the boat. I’m open to other ideas.
II. Hands-Free Controler - I’d like to make navigation hands-free. Has anyone seen a ‘hoverboard’ controller attempted? The idea is to use four force-sensitive resistors in a foam mat, controlled with foot pressure. The four sensor set-up would be: 1. forward-left, 2. reverse-left, 3. forward-right, 4. reverse-right. Any ideas on how to pull this off or on how to improve the design would be incredibly helpful.
If you want maneuverability, mount T200 on mechanical rudder. On the sea wawes turn you in parralel with them. Wind push you from the direction. If you want steering with 2 T200 you might have big turning radius.
