thanks brother; floaters are the very first solution that came to my mine. I’ll go first for the side float. It’s an easy and adjustable fit using two carbon 14mm tubes and attachement directly on the USBOX rails. I’l also try to move the cable below the board and that will help for sure in the board going nose up high.
Your statement that two motors are heavier than one has disappeared somewhere. The weight of one FS65161 is 3 kilograms, the weight of two 6384 is 1.9 kilograms. Maintenance - pull off the rotor, spray corrosion X. Service 65161 - unscrew 6 screws, remove the seal at the risk of damaging the o-ring, replace the rusty bearing)
here we go. If it works, I’ll need to secure the tubes. the tighteners are 15mm and my tube is 14mm… I added some rubber but not sure it will do the deal. Maybe a 3D printed part to mind the gap would work but it will have to be chirurgical… 1mm thickness (max)
An interesting solution, of the minuses is a significant increase in size. I planned on my first tow boogie to make something like a wing on a mast with blades directed at different angles.
I’ve been pretty busy at work, not so much time to work on the tow.
few updates/highlights/feedbacks:
the pelican case works very well to keep water outside
I’m going to had some weight on the nose to avoid the tow going nose up. I plan to start with 2/4/6kg. If that works I’ll see if I dig the lead into the nose or just add a belt and put the weight on the belt
I’m also going to add a 25mm aluminum tube like @Jatem did to benefit from the lever effect and also to channel the cable. I have two USBOX that I can use… but I need to have the cable escaping the board by the middle. Not sure about the length of the tube.
I got some weird behaviors where the controller was delivering power and then stopping. very weird. Maybe it’s a RPM thing? don’t know yet.
I can also install two footstrap nylon holders and epoxy two of them in the middle of the two USBOX and attach the tube to them (takes more time) but avoid to have the two 5mm plates, additional screws etc… like this
I have had they same thing where the motor gives full power/ then suddenly stops, only during deep water starts pulling the full 6kW.
A while back during assembly my phase cables were damaged and I put heat shrink over them with glue and grease. I think it may have been shorting out at high current during full power.
I haven’t disassembled to confirm yet, but will let you know if it was the cause. Nothing else with my set up changed.
