Some lessons that I've learned
- Keep weight low. The closer to water the less likely your precious creation will end upside-down
- A smaller prop keeps the motor lower, and easier to keep the weight low. Select a motor with a higher KV to allow for a smaller prop.
- Keep the boat nice and long. This keeps you from creating a water plow.
- Waterproof your parts. A little water in the motor won't kill anything, but ESCs are particularly sensitive to moisture. Receivers will tend to rust pretty quickly when wet. A cheap disposable tupperware or even dipping the ESC and receiver in epoxy seem to work.
- Components get hot when there is no ventilation and when they are surrounded in foam. Let me know if you figure out a cheap solution to this...
- Fasten the battery down. Failure to do so could lead to the boat flipping over in the middle of the pond at the local golf course.
One of my friends built one, too. Hopefully we'll get a video of them racing
