Is a ball link on the throttle arm on the carb a good idea?

I use them on all my planes. I use the plastic ones and solder the adaptor to a throttle cable. It makes for a clean hookup. They hold on well and after a crash that totaled out the plane, ripping the engine and firewall off the plane, the ball link was still attached. I run four strokes, so clearance to the firewall is sometimes an issue. In those cases, I cut the adaptor down and also cut the body of the ball link off. I can gain about 3/8" to 1/2" this way and that is usually enough to keep the linkage from hitting the firewall at extreme travel.

I like these on the throttle. Don't need to open up the holes in the carb arms.

These are my favorite also.

Same here. Just remember to put a spot of thread lock on the nut. I had one come off in flight. Wide open throttle with a full tank. Seems like forever before it ran ou.

I keep forgetting to mention the obvious.

Throttles are the most forgiving of control movements on a model. Throttles and nose wheel steering rods are the only place I use Screw-lock connectors.



The ball-socket connector with a "Z" bend or Fastlink at the servo arm is much improved over the screw-lock method.

hehe my buddy lost his with a gasser running just above 1/4 throttle, too fast to land but it took like 45 minutes flying in circles to run out the gas.

Hi!
Not that good ! A plastic snap keeper is much easier to unlock and trim.

The ball link makes an excellent throttle attachment, especially if there is a slight offset between where the pushrod exits the firewall and the throttle arm is.

And not metal to metal either.

hey guy ... you and I read the same book!! egg-zakly how I set throttle up also. Works great, and no slop, etc

I've been using ball-links for throttles for around 30 years and haven't have any problems with them.

You can't go wrong with ball-links .

Make sure there isnt any side force on the ball link

had one come off in flight.... Sait carb closed itself because of the spring.....

you must make GOOD solder joints . i HAVE USED ez CONNECTORS FOR 25 YEARS WITH EXCELLENT RESULTS, LIKE anyOTHER CONNECTOR(AND THERE ARE DOZENS OF WAYS TO DO IT) YOU MUST UNDERSTAND THE PROPERTIES OF EACH METHOD.
