Functions as expected. Note - This replaced an identical item that failed after being cleaned with brake cleaner, which dissolved the polymer inner linin of the cable.

Excellent for a super cub as they have limited room on panel for vernier style. Good detentes for accurate leaning

Sending parts to Europe from the US is faster than ordering the same part from your European subsidiary! Fast shipping of a great product! Thanks a lot.

Really like these control cables. They move freely but they also dont creep in flight. Win win. Used in every Super Cub I have rebuilt with no complaints.

This is not a locking cable. The shaft has internal notches, and as the knob is pushed in or pulled out you feel the ratchet effect which holds the cable in position.
The inner cable is .050" diameter, and the outer housing is 3/16" O.D.. The mounting hole is 3/8".
Per Vendor, First you would have to check if the spring is still in its slot. If it is, then you would have to take the total control out.
The knobs can be removed if the cable is ordered that way, otherwise it is loctited on. The OD is 1 and the threads are 10-32. Please contact our sales department for price and lead time of special order controls.
The maximum extension is 3-3/8" and the diameter is 3/16.
No. The only FAA PMA Approved ACS controls are the A-790-12 and the A-800-12.
No, the detent pressure cannot be adjusted.
