Notes
The servos for the wee footy need to be light weight but still have reasonable strength. We tried a few brands and sizes and the Emax servos we find are a good balance of price and quality with enough power.
The battery needs to be a 4AAA square pack to fit the battery box. The weight distribution and placement of the battery is critical to the balance of the boat.
The B-rig sail is the best all-round choice. We recommend building at least 2 sails, the B and C rigs for a wide range of sailing conditions.
