Ross, My 'Wild Thing' has a Hi Tec 81 on the throttle and a "standard" Hi Tec on the rudder and remote mixture. The standards I have are HS 303's. They came with the Hi Tec Ranger III radio system I use. My guess is they put out around 40 oz. in. of torque. You don't need any more than that. I would have used an HS 81 on the mixture but the control was pretty stiff and I had the extra 303 on hand any way.

By the way, I brought a digital camera home from work this weekend and got some pictures for you. I'll have them in an E Mail to you early this week. Gotta have someone at work show me how to down load them into my computer. You'll see the boat overall and some details of the engine compartment and the transom area. Also you'll see that the rudder (Speedmaster) is cut off to just about the water pickup hole. As Ron indicates, the stock rudder is far to long.
