Remotely control a K-Nex sailboat
Summary
Overall, our basic sailboat worked fine (Figure 7), but we could have improved the design by experimenting with the sail size, mast position, and boom line length. Another improvement to the project would be to use the D button on the remote to turn lights or a horn on and off.
