Okay, once again new to nitro boats, so take it easy on me! I just bought a Shockwave 36, and checked it out this afetrnoon on the bench. I reset the rudder linkage and throws, removed and lubed the flex shaft, checked everything for binding, loose fasteners, etc., and all looks well.
However, I have a question regarding setting up the throttle. On my old electric r/c cars, pushing the trigger forward from the spring loaded neutral meant brakes/reverse. With airplanes, there is no spring loading of the throttle stick; it just stays where you put it. Of course, w/ a nitro boat there are no brakes or reverse, so my question is this: Should full travel from closed to open---that is, the rotating barrel in the carb bore from closed off to full open---occur when the trigger is pulled from "neutral" at the trigger's spring loaded center to fully pulled back? Or should neutral (again, the spring loaded center on the trigger) be half throttle, necessitating pushing the trigger forward for idle and pulling back for full throttle?
It would seem to me that you'd want as much travel as possible from idle to wide open for better sensitivity and easier modulation of the throttle, but it would be odd to have the carb at half throttle when the trigger's at neutral.
I hope this makes sense! Also, is it possible or adviseable to have it set up so that one could close the throttle and stop the engine from the transmitter? Or do you just drive the thing right up onto the shore and put a finger over the exhaust outlet?
Again, please excuse my ignorane, and thanks in advance for any help...

Ok ,
pistol style TX's =
when at nuetral ( middle ) engines idles at lowest speed possible .
when pulled towards you - engine is at full bore
when you push the trigger forward - away from you - this shuts the engine down via the carb being totally closed .

Being able to shut the engine off with the radio is real handy especially when bringing the boat in to shore. I have one that does not do that and it can be real tricky to bring it back for adjustment w/o messing up the prop or the boat. Just tell others that you let drive not to push forward while the boat is in the middle of the lake. I've got a buddy that uses trucks a lot and he cannot seem to remember that with the boat foward is off not stop.
