Tried my assist board with tow rope today and it would torque roll over until motor was out of water that was with a foil on mast upside down to try keep board nose down and rope attached to rear of board .
I don’t know how you can counter act the roll. I don’t think a rudder with an offset left turn would be enough. I think it’s got enough power to get me going if I can get it to drive straight.
We use a modified Manta remote with our own custom firmware, it’s heavily integrated with the single motor steering mechanism so wouldn’t work for dual motor or servo steering systems.
Roger thanks for feedback seems to be an issue in foil world to get good remotes with more channels
For the stock remote, I think @Mantafoils last April (2025) said dual motor steering would be possible with some extra development but not in the pipe atm.
