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.

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.

31mm or 32mm prop will match with your motor's wattage.

22" to 26" hull size max.

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.
