1) Do the brushless motors need to be waterproofed for submerged running?
2) What brands of motors are efficient and reliable?
3) What speed controllers are most reliable for RC motors?
4) What RC controller would be best to control 2 motors independently with forward and reverse?
5) Can the RC set up be done easily with a common 12 volt battery?
I am trying to do this on a budget so cost is very important. I hope I am not asking too much.
Thanks in advance
I've never built an e-boat but will try to answer your questions as best as I can.
1. Yes. Hal sensors do not like getting wet. Brushed motors work just fine submerged. I'm not sure how well one would hold up long term, unless specifically designed for submerged operation. I'm not sure how you could go about sealing an RC motor.
2. Lots of people like the larger Turnigy motors from hobby king. I know HK is in the middle or was working to replace their lines of large motors with a new motor. I'm not sure oh the names of those replacements or what's out yet. I just recall mention of a lot of their stock is on back-order because of this.
3. The problem with RC controllers is finding the one that can handle your power needs.
4.12 volts is a bad idea. It will be pretty slow and pull massive amps if you try going faster. 24 volts would be much better.
