This is excellent; exactly the info I've been looking for. Thanks Patmat. I like that Airtronics ESC; can it be used with Futaba receivers? Also, if you wanted to run a twin screw setup, is there a radio that will permit controlling each motor independantly providing you install 2 ESCs? I bought a Kyosho palmcruiser that uses the twin props to steer with, and it sucks. Very little control with assymetric thrust/cheap supplied radio/no rudders. Sorry for all the questions; I'm getting back into R/C boats again after about a 15 year hiatus.
