Oh man! I gotta give a big thumbs up to the people at Aircraft Spruce!! I landed at Osh with a broken mixture cable (YIKES!!) and needed to get this squared away so I could enjoy the show. First stop was to Spuces booth. They had the cable right there!! I did have to order a cable end, but they got it to me the following day. Aircraft Spruce has ALWAYS come through for me, for all of my airplanes, over many years. These guys are ROCK STARS!!! Peter in Sacramento, CA

Just what I needed. Perfect length and I didn’t need to cut to fit.

To straighten this control out, FIRST pull center wire out slowly until locking ball FALLS OUT AND IS CAPTURED, then continue to remove center wire and straighten as needed. Reassemble and reinstall locking ball to original position.

Installation was easy, and was a quality product just as expected. It even came with a tag reminding me not to pull it out too far, which would be easy to do, because a small ball will fall out and it could be difficult to replace.

This mixture control is high quality and works smoothly. The price compared to other more well know brands is extremely reasonable! Well worth the price! Would buy again!

Q: What is the outside diameter of casing of the A-790 vernier control? In order to use cable safe products.

Q: Can the sheath and cable be trimmed down in length if the old model falls between selectable sizes?

Q: Can the A-790 VERNIER CONTROL solid inner cable be removed from the outer casing so that the casing can be cut, or must the casing be cut with the inner cable in place?
