Simple paddleboat. To power paddlewheels you will need 2 continuousrotation servos. Or regular 9g servos converted to continuous rotation.
Supports are required for both hull parts. They can be skipped for paddlewheels. Brim is suggested for hull parts.
You will need one of each part of hull, 2 paddlewheels and one rudder
Both hull parts should be glued together. I used CA and epoxy reinforcements from the inside.
