I did some reading around and decided I want to experiment building a 'simple' WTC basically containing radio, a peristaltic pump, and a latex balloon to see what it takes to make: sub go down; sub go up. I have a 3d printer so I think I should be able to make ABS end-caps and some modular internals. Propulsion later, I thought.
This all being well I started looking at radio, because I've been in 2.4GHz land and didn't know about this *water* stuff. Turns out this isn't a boat hobby at all is it? It's a radio hobby!
I *think* I want to go along the turnigy x9r + 433Mhz modules route, but I don't know how to set up the build to re-flash them to 458Mhz. I have re-flashed my 3d printer brain though so I assume it's not a dissimilar process.
So, hi. I'm cat. Total newbie and quite intimidated by the radio proposition :)
