I am mounting a magnum 180 4 stroke on a Big Bingo. Problem I am running into: As you can see by the pictures the throttle level is too high to run the cable. Can the throttle lever be turned around and if so, how? I don't see anything but what I believe is the LSN screw. Thanks. I can provide more pictures if that will help.

I don't know about that engine but my other engines have a small set screw on the side of the throttle body.
Look all the way around it.

Goirish,
Simply bring the pushrod out and then bend it back around to the throttle arm.

A second solution is sold by Dubro. It has the pushrod come out of the firewall and go to a control arm that pivots on the engine mount, and then a second rod goes back to the throttle arm.

My preferred method is the first one, bend the pushrod into a U-shape.

As always great help on RCU. Thanks Ken and Missileman.

I often use the method Ken suggests, works very well. It also allows you to bring the throttle pushrod out right next to the fueslage side (easily missing the fuel tank) then up and back to the throttle arm. On some you may want to put a guide on the side of the fuse just before the bend so minimize any movement due to vibration.

The throttle arm has A set screw and you can rotate the arm 360 degrees and all points in between. You can also rotate the carb 180 and run your throttle on the other side. What Ken is showing works very well on A lot of those hard to reach throttles. I use cable mostly and often make up my own linkage using U-Control arms and items from kits for aileron control linkage. Sort of like Dubro only free, I like free.

Just is case you want to try Ken's option #2

I may get one of those so I will have it on hand. Thanks for the reply

I tried Dubro four strok linkage on a couple planes and was not happy with it. Like Grey beard, I use cable for my throttle linkage. It is easy to route around things and has more than enough stiffness to do the job. I use a ball link on the throttle arm and that extends it out a little further to the side. Some times, I have had to cut the threads on the solder on end and also on the ball link socket to get enough travel on the firewall side. Just make your exit hole near the center of the throttle arm movement and there is enough flex to accomidate a slight miss alignment.

I'll add one more thing, you might try turning your carb 180 and see if it gives a better approach to the throttle linkage.

You are learning to mentally layout how every part will go into the plane, before you put any coverings on it.

I always go with 1/2A push cables. It should be a almost straight shot to the lever from the 55 servo.

I also run my cable through that nice little yellow push rod tube and brace it inside the fuse so there is no flex. Pretty good stuff, you can go around bends and stuff with it. You can also drill A hole in the motor mount and have that push rod tube just come through so the cable is A straight shot to your control arm. I sometimes solder on that brass threaded end stuff on one end of the cable and A Dubro clevis on the end that goes to the carb. {if I have enough room} An easy connector on the carb control arm with the metal keeper hammered on stays nice and tight and is an easy set up. I do use A lot of easy connectors too. Just sit back, look at your problem and the answer will jump up and bite you in the hinderpoo.
