View Full Version : How to install rear throttle on Exp cub?

I am in the process of buying a EXP wide body supercub, that has two doors. It currently isn't equipped with a rear throttle. How would one install a rear throttle considering the left side door cutout? Perhaps a flexible cable of some sort, or push/pull rods? Any opinions out there?

My 12 has double doors. I left the rear throttle out, and doubt I'll ever miss it. I don't sit back there. Besides, my wife would probably use it as an "Oh Sh-t" handle when she got nervous. (I'm rationalizing.)

If you're going to use the plane for primary instruction, you've got a problem. I suppose you could fit a temporary rear seat throttle that piggy-backs to the front seat's unit. The connecting rod or cable may interfere with the left door a bit, but not too much. After all, you don't have to ask for FAA approval.

Another thought. Ursa Major parks next to a certified Cub with an STC'd left door. You might ask him to take a peek and see what that guy did, if he did anything.

Check out the pictures on the Smith website. They use a rod run under the door opening, that connects to "arms" extended down from the throttle handles. You will also want to move the trim to overhead.

Here are a couple of pictures from the photo gallery that I took at OSH 2002. Shows the left door/throttle set up.

John Scott,
Thanks, that is exactly the kind of information I am needing. There is a problem, however. The problem is that the aircraft has already been covered, so any addition of a rear throttle will be a challenge, but also, thats why I favor experimental, one can just do what they want, without the FED getting involved. I'll let you know when I get it home. There are still bridges to cross due to the 40 hour flyoff time needed.
