Hey guys,

I have a goldberg sukhoi I am currently "fixing up". It currently has a wire for the throttle. Im not sure what size. But I would like to convert it to a solid line. Any tips for this? I bought a 2-56 rod and some new guide tubing and just figured Id play with it and see what happens. The way the old wire was set up the line had to be wire tied to the pitts muffler to prevent give. I just want a solid set-up. Oh and its a Supertigre 1.2 2 stroke. Its mounted 90 degrees to the planes right. Any tips would be appreciated.

Thanks,
Erik

Also what size spinner do you recommend? Ill be running a 16X10 prop.

My means of throttle hook up is by means of either a wire or cable run inside a plastic tube. tube provides ridigity and can be glued to any supporting surfaces. No problems, ever.

The throttle usually does not require much torque. Any wire (2-56 is fine) will do. Actually, some use a micro servo in the engine compartment and a short length of linkage to the throttle arm on the carb. The important part here is to make sure your servo movement is not limited or bound by end points. Do not allow the servo to move further than the throttle will allow it to or binds and over-current conditions will happen.

So, carefully set in the servo with the linkage and move the throttle arms by hand (not electrically) to make sure that the linkage moves freely. Then apply power (turn on you TX then RX) and then move the throttle from end to end and see if there is any over-movement of the servo. What I mean by that is once the throttle arm stops moving, so should the servo arm. If the servo arm still moves after the throttle arm stops, this is binding and will cause serious problems. Adjust this out either mechanically (move linkage in closer to the center on the servo side or out further on the throttle arm side) and re-check it. If you still can't get it right, then end-point set on the throttle in the TX setup is necessary... if you have a computer radio that is.
