Mini Speed Boat 3-ish / Tiny Whoop Boat

thingiverse

This was a remix of the Super Simple RC 3D Printed Speed Boat by SamFoskuhl. Inspired by Wersy's Speed Boat 3. Took the base deign made the hull one part, added mounts for the flight controller, add screws and seals for hatch to try to make water tight (not very successful). To make water tight, I coated the entire thing with 2 part resin. For gaps around hatch, I first tried RTV seal maker and that didn't work. So after i screwed the hatch shut, I just ended up just filling the gaps with petroleum jelly to get up and running and that worked like charm! The motor mount and prop cowling were super glue to the hull after coating and testing everything. Used a tiny whoop flight controller BetaFPV 65s to control 2 tiny whoop brushed motors. Used BetaFlight configuration "Custom Airplane" configuration for differential steering. Still needs some tweaks on the motor mix settings, but initially used: mixer CUSTOMAIRPLANE mmix reset mmix 0 1.0 0.0 0.0 0.3 # Left Engine mmix 1 1.0 0.0 0.0 -0.3 # Right Engine smix reset smix 0 3 0 100 0 0 100 0 # Roll / Aileron smix 1 4 0 100 0 0 100 0 # Roll / Aileron smix 2 5 2 100 0 0 100 0 # Yaw / Rudder smix 3 2 1 100 0 0 100 0 # Pitch / Elevator Servo settings included but not used. Next steps: 1. Needs an on / off switch or maybe separate battery compartment 2. Steering needs work... not sure if motor mix values can be adjusted to help. 3. Change steering from yaw to roll control to utilize both joy sticks and a more natural feel. 4. Better waterproofing. maybe a separate compartment for the flight controller. https://youtu.be/s8y76_c45Sc https://youtu.be/Xe9JslOWl6I https://youtu.be/xQuHD4jmooo
