Status: offline 		Just to let you know my experience with a twin engined 70cm V-hull project I did some work on.

Using a low cost Chinese model, I ditched the electrics, fitted proper CW and CCW 380 tuned motors, dual ESCs and a V-tail mixer to get the right signals for the motors. But it just didn't work out well; Nice speed, but terrible turning and insensitive steering. Maybe more adjustments to the V-tail mixer inputs could have done the trick, but I doubt it.

So, now the hull is getting a conventional rudder and the motor will be tied together (electrically). Should I also add a turn fin? Or should I go for dual rudders instead? What rudder / fin configuration (two props, remember) would work the best?
Center rudder, side fin(s)?
Twin rudders, center fin?
 
Inputs very welcome!

Thanks / Mike

Going to set mine up with a center rudder,upgrade to 2 good 380 motors and a good esc. Going to use 2 duratrax VR3 high rpm 380 motors, or 2 traxxas titan 18 turn 380 motors. Or go 1 BL motor Larry
