This compact aluminum control allows easy access for standard casing and 1/16 control wire. Eliminates the need for expensive and bulky quadrants that require special mounting and end fittings. Block is countersunk to accept throttle casing as shown. Inner wire wraps smoothly around wheel providing a full 2 travel (Bing Carbs need 1 1/2 travel) in less than 1/2 revolution of the handle. Set screw shown firmly anchors wire. Back up swage makes for a fail-safe and completely variable length and design. Short handle controls precision tension adjuster that makes for a throttle that positively stays where you set it.

Mounts to any 3/16 or 6mm fasteners.
Bolt centers are 1 7/8 Handle measures 2 long.


Nice functional part. I replaced the spring washer with a large o-ring to soften the action - but that was just my preference. Great service from AircraftSpruce

Nice, got rid of the issue with having to adjust the tension several times a flight. Bad was no support from AS on getting a cable stop to fit this device.

Just got it and it seems to be made well. Due to poor picture on website and only one angle shown I was unable to see that it can only mount on right hand side ie: you cant screw it onto the left hand side of cockpit because cable inlet only points one way. They should make a left and right hand side version and save us a lot of fabricating.

Required rebuild out of the box to make it work. Built like a tank so it might not be optimal for your Part 103 Air Vehicle. It weighs a bit over 1/4 pound (115 Grams). Dimensions as pictured are 3.2 inches by 2.5 inches. 0.7 inch thick. It has meshing radial serrations that click into place. It has a very strong wavy washer which requires 15 pounds force to ratchet over the radial serrations. Because of the large force required to move the lever, it requires a substantial mounting. You can loosen the screw to where things are loose and still requires 5 pounds and you would need to add a lock nut to the back so it does not fall apart. I do no know what kind of carburetor pulls back with 15 pounds of force. Update. I just replaced the wavy spring washer with a 12.6mm o-ring with a section diameter of 1.9mm. The 1.9mm section diameter is important. It was the largest O.D. in my o-ring kit and I had to stretch it into place. Now it has a sweet 5 star movement that I can move with my pinky and not vibrate out of position. The wavy spring washer is 0.8mm thick with a spring height of 3.4mm. That is just wrong.
