I was planning to us 3500 kv L series motor on 3 lipos with castle 120 would this work and would I get speed in the mid 40mph with this set up thanks

1/12 elam hull

I have Miss Llumar 1/12 and Miss Vegas hydros and I decided to convert Vegas into electric instead of Llumar due to Llumar having too little space in the hull. Elam is about the same as Llumar. I don't think you can get Elam to do 45 mph without problems both in stability, handling and electrically. To get my Vegas to 45 mph required about 1400 watts of power. To get the runtime i wanted i needed many batteries, and you will not fit half as much in Elam. Battery weight required more power from the motor to get to the speed i wanted. So if you manage to keep your boat featherlight, you will not need as much power to get to 45 mph as I, but your boat will catch wind and flip before you can get there. Conclusion is that i think you will not get to 45 with that hull with your power setup. If you do, any real world chop on the water will flip the boat at that speed. And if you keep your battery small, the runtime will be too short.

1/12th ProBoat Llumar + 9XL + SV speed controller +1 pack of 4S 4500MaH LiPos mounted over the radio compartment + a standard SV 27 3 bladed prop =44 Mph.

Been running that setup for about 2 years now and its still going strong.

Cool, looks like i don't know it all... Does it flip in rough water at full speed? Do you have video of it running?

Would 6xl 2700kv with 3 lipos work to and which prop should I use

I believe that would work as long as you watch temps, amps etc. I have a Miss Bud that I run a 9L on 3s1p, 60 amp ESC with a y535. It's not the fastest but it's fun to watch. I'm going to upgrade to a better ESC and put 4s1p in to make it a little more exciting. The main thing is to keep trying (within reason) various configurations to get what you are trying to achieve.
