Throttle Linkage Hookup

       Remove this ad - become a site supporter!
This pertains to an OS FP Series engine.

I am trying to hookup the linkage to the throttle barrel arm. The problem is, the throttle barrel arm is too close to the engine. What I mean is, when I hook up an easy connector to the throttle barrel arm, the back of the easy connector rubs against the side of the engine (where the carburetor is). When I try to hook up just a plastic clevice to the throttle barrel arm, the clevice also rubs against the side of the engine.

So how do you connect the linkage to the throttle barrel arm, without it binding?

Since there are fairly common engines, I'm curious if anyone has this problem.

Very carefully bend the throttle arm away from the carb, it will move just be gentle and only move it enough for the clearance needed

Why not just use a Z bend on the throttle end? move away from any connectors.

throttle linkage hookup

I agree with Alan...
Use a Z bend at the engine and use the EZ connector at the servo.
Don't use too heavy of a wire. In case of a crash, a bit thinner wire may save your servo from getting stripped.

Some just make a right angle bend in the wire with the piece going through the linkage hole being long so it won't slip back out. Put it in from the engine side of the link of course.

Also, a brass clevis is smaller than the plastic type. (but then the treaded 256 rod is haevier than what you need to use as well.)

Further to what Tinman said, it is possible that the throttle arm was pushed in from sitting around in the shop. You should be able to install a clevis and not have it bind. I usually bend them out a bit (very carefully) if I have this problem.

All good suggestions, although I don't like to use a metal clevis here if the arm is metal. Metal to metal connections can reuslt in something known as "sparking" under vibration. Although new receivers are more resistant to this type of RF noise, why take the chance?

Personally, I prefer a ball link on the throttle arm. This setup will not only gives you the extra clearance you're looking for but the result is a smoother linkage and easier maintenance (ball link pliers work well in tight spaces).

for the suggestions. My concern was with what Jim was talking about - metal to metal contact. Also, the throttle arm is plastic, so I'm not sure how well it will bend. Perhaps I'll try the ball link suggestion. I might also check out to see if there are throttle arms that angle out - like on the new ax engines.

Lke Jim reccomends I also like the Dubro ball end and you can get the one with the stub that is less than 2/56 which fits the smaller glow engines. It just snaps on and works like a dream. For the metal to metal connection is what I was having problems with. Straightened it out going to the ball link. That was last week on an engine change.
