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. The base design was taken and modified to create a one-part hull, with mounts for the flight controller added, screws and seals applied for the hatch in an attempt to make it watertight - unfortunately not very successful. To achieve water tightness, the entire thing was coated with two-part resin. For gaps around the hatch, I initially tried using RTV seal maker but that didn't work out, so after screwing the hatch shut, I just filled the gaps with petroleum jelly to get up and running, which surprisingly worked like a charm. The motor mount and prop cowling were super glued to the hull after coating and testing everything. A tiny whoop flight controller BetaFPV 65s was used to control two tiny whoop brushed motors. The BetaFlight configuration "Custom Airplane" was utilized for differential steering. Some tweaks on the motor mix settings are still needed, 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 were included but not used. Future steps include: 1. An on/off switch or separate battery compartment is needed. 2. Steering needs work, and it's unclear if motor mix values can be adjusted to help. 3. Changing steering from yaw to roll control would allow for both joy sticks and a more natural feel. 4. Better waterproofing could be achieved with a separate compartment for the flight controller. https://youtu.be/s8y76_c45Sc https://youtu.be/Xe9JslOWl6I https://youtu.be/xQuHD4jmooo
