    Twin brushless V-Hull

    Hello, just wanted to share this build, heres what i got so far

    It is an 80cm Deep-v fiberglass hull.

    I was thinking submerged drive, either twin 2845 2000kv on 3s or maybe a single 4050 2260kv on 3s, any thoughts?

          Definitely need to lift the rudder up like 2 inches.

              When on plane only 2 inches will be in the water

              Remember im going for a rigid shaft submerged drive where the prop exits under the boat

                  You'll get a lot of drag at low speed. Your boat but I made this mistake awhile ago and the boat performed horribly when turning at low speed.

                      I'll try, if the rudder is too low i can move it higher.

                      As i will be running in saltwater i will try to keep it as watertight as possible, hence the walmart box

                      Im thinking of a 40xx motor turning a big prop at reasonably low rpm, maybe a 4074 2000kv on 3s?
