A fairly simple airboat. does well in short grass as well as shallow water. Wouldn't recommend using it in deep water but it works well otherwise.
Propeller is an interference fit with the body of a 2212 motor but I haven't had any issues with it staying in place so far.
all you need are bolts to hold it together, a 2212 motor, a 9 gram servo, and a bit of glue to hold the servo into the rudder. plus of course an esc receiver and battery. I tested with a 3s lipo and everything held up well.
the rudder may get a redesign to accept a proper servo horn but for v1 it works.
TO MAKE THE MOTOR FIT YOU NEED TO USE WASHERS BETWEEN THE MOTOR MOUNT AND MOTOR

Will be updating over time as I find issues with the design.
