Status: offline 		I have two 2445 3200kv 350watt motors to go into cat hull with twin drives,(have plans for mystic 5000r which I can scale up or down to suit) and 3s 11.1v lipo for each motor, what I need to know now is what length/size hull is needed for this setup, also prop size/pitch ballpark figures would be of great help. Much thanks in advance. Steve.

Status: offline 		I wouldnt go too big. Larger the boat and lower the kv needed to keep it moving with torque. With 3600kv i wouldnt go over 36". Look up your motor size compared to simialar kv motors. You should be able to find a close match of recommended prop. Keep in mind no setup is the same and small fluctuations in variables add up and thats why unplanned setups often have problems.

Status: offline 		Yes, those are tiny motors not well suited to a 36" cat. I ran a single that size in a 17" cat and it ran very well. Between 24-27" should be great with twins.
