Notes
Batteries
For best performance, use a 4×AAA square battery pack or a lightweight LiPo. These options help reduce overall boat weight, improving handling and responsiveness.
The battery compartment is sized to fit a standard 4×AA square pack, giving you flexibility in battery choice. If you choose a smaller battery, use packing foam to fill the space and ensure the battery sits securely without movement.
Servos
The servos listed on this page are recommended options, but many alternatives will work just as well.
The servo tray is designed around the dimensions of these suggested models, so when selecting your own servos, check their size and aim for similar measurements to ensure a good fit.
