Hmm. This is worded interesting. It says you cannot INCREASE power at all to aid manueverability in a turn, but it doesn't say anything about cutting powwer to the screws on the inboard side of the turn in order to aid manuverability. I'm assuming this is a Big Gun rule, not Fast Gun, correct?
I don't know of any fast gun clubs that allow differential power for helping turn. I wanted to do it when I first started, but it'll be hard enough getting the ship running reliably without adding complexity to the mix. And, nobody else one the water will be able to do it, so you won't be at a disadvantage on that.
For those that don't know- Turning motors were baned from "fast gun" because they were too effective. So much so that if you had an inadaquate system, you were a target. Once the allies put the on the S.D. the axis did not think they were fun anymore, and everyone voted to get rid of them.
Really, having originally been "what?!? I can't using differential steering?", now after a few years it's not really an issue. You can work to make your ship turn better (more mass in the center, better rudder placement than stock, etc).
On my new Roma, I have all 4 props powered, and I'm using a new type of speed controller, that has the ability to mix the forward and reverse throttle control, with the rudder control. I hooked it up, and man my Roma could turn circles around anybody. If I just moved the rudder control, the motors would run in reverse from each other, and the bow would not move, and the stern just rotates around the bow, or going forward with full rudder throw, it can turn very fast in about half its lenght, but MWC said no way, but it was just for trials anyways, I had no plans to use it, LOL. All I had to do was change a few dipswitches, and unplug the speed controller from the Y connector attacted to the receiver rudder plug to make everything normal again. I think the next local battle I will plug it back in, just to give some people a fright. Tugboat may even see it, if he comes down, or I come up.
Now that I am in the rc naval combat business full-time, I will be making all battles, and can write it off on taxes as marketing expenses And David, you _must_ show me that, even if it's disabled during battle. Sounds really cool.
I have one of those too... Although I gave up on the concept after seeing how complicated it was making everything. You want it tuggy? I'll sell it to you cheap! --> Might not be too complex on that battlestations! boat of yours!
Mine was very easy to hookup, its from Dimension eng, the Sabertooth dual 10A motor driver for R/C. Works great with the 700/650 series motors. http://www.trossenrobotics.com/store/p/5106-Sabertooth-dual-10A-motor-driver-for-R-C.aspx
The New Roma has a good turning circle and it only uses 2 inboard props. I angled them towards the center line of the hull to direct a larger wash over the rudder. The Rudder is scale size but the props are large. More data will be avaialbale once I try a samller set of props to reduce the speed. Should help the turning circle even more.
