Overview
|
The A-800 friction lock control provides positive locking at any power setting by turning the chrome collet locking nut. Unique ball-socket construction permits 10-32 threaded end to swivel 8 degree in any direction. Casing has Teflon liner for low friction and heat resistance in high-temperature areas such as engine compartments. Travel: 3-3/8". The 1-1/4" dia. solid knob is available in black or blue (blue knob has smooth profile, not FAA style). 1/2" panel thread. Lengths are measured from under panel nut to end of threaded shaft with knob pushed in. Made in USA Experimental Aircraft Only |
Reviews
It ships knotted as shown in the photo. The first one arrived with a big kink in the flex line where it enters the tube to the carb. A nice gal at Spruce arranged a replacement at no cost. It also arrived with a kink there but not so severe it couldnt be used. The control knob has a nice feel to it in operation.

Works very well as part of a dual-throttle setup. The friction lock was easy to remove as is needed for a dual throttle setup.

No issues with the installation, the 60 inch version was exactly right for me. Nice smooth operation from idle to wide open.

I did not use this. I messed up by ordering the wrong length. Measured 2 from the instrument panel to the firewall and then 4 feet from the firewall to where the end of the cable would be. Then I preceded to order a 4 cable instead of a 6 cable.
Great cable and great price. As the other review says, the knob is a little rough. I removed the knob, put it in the lathe and was able to quickly smooth out the mold lines with some 400 grit sandpaper. Then with a light touch of flame from the torch the knob came out smooth and glossy, looks great and feels good in your hand.
Nice good quality throttle cable that is more than adequate for my needs especially at 1/4 the cost of the quote I got from Mc-- for essentially the same unit. My airplane had the same ACS throttle only with a vernier control which I discovered I very much didnt like the first time I had to do a go around. With a vernier throttle you find yourself hunting for the release button to add power when time is critical. Thats a non player in my book after 40 years of aviating. The knob, although standard, is a little chinsier looking that the other brand but I was going to replace it with a nice aftermarket carbon fiber or billet alum shift knob from eBay anyway.

The largest diameter is approximately 3/8".
1/4" O.D. on the cable but the swaged on part is 3/8". Customer would need to drill a 3/8" hole and use a AN931 grommet.
The diameter for the hole would be 1/2".
The threaded section is .70".
4.25"
No, it is not recommended that these controls be cut.
This will have a 10-32 threads at the end of the cable.
Yes the Vans version of the A-800 has a bulkhead mount. See Part# 05-01436 for Vans version.
The Vans cable (Part# 05-01436) has the threaded bulkhead a the engine end and you can order it in custom stroke lengths.
