Skunkworks85 Posted March 5, 2019 Report Share Posted March 5, 2019 I thought I would share one of my personal accessories that I have designed. I was frustrated by the lack of a decent Gust Lock, I did see Rodgers' Ace Aviation gust lock, but I also wanted an aileron lock as well. I designed and printed the Stick End and the Rudder end, The intent is to swing the stick end up and it locks on the bottom of the outboard side of the rudder shaft, then rotates down to engage the control stick, There is a channel that hold some hook and loop material to lock it to the yoke. The aluminum rod is 3/4" al tube from your local hardware store, the end pieces are epoxied on, with the intent of having a rivet for back up. I will post some pictures in the future of it installed in the plane. Total weight is 248.6 Grams Here are some renders in CAD Link to comment Share on other sites More sharing options...
cdarza Posted March 6, 2019 Report Share Posted March 6, 2019 Nice to have a gust lock as you have shown. For a simplified version though, bungee cords work really well for me. Link to comment Share on other sites More sharing options...
Runtoeat Posted March 6, 2019 Report Share Posted March 6, 2019 You might go into business with that. Looks pretty professional. I assume by your comment about "printing" and the clean design of the ends means the ends where formed by a 3D printer. Link to comment Share on other sites More sharing options...

It is still in the prototype phase as I have yet to actually use it, There maybe some fine tuning of the rudder end still to do, to get it the way I want. I should know after this weekend. I also want to design a clip bracket that the gust lock will snap into for storage during flight. That will be next on the list to complete.

AGLyme Posted March 6, 2019 Report Share Posted March 6, 2019 Smart idea... thanks for doing this. PS y'all... still looking for a co-pilot's rudder pedal cover... need it for my oldest who has CP... if anyone has one for sale, I would buy it.

Skunkworks85 Posted March 11, 2019 Author Report Share Posted March 11, 2019 Here are some pictures installed in the plane, Used it today on a trip, Worked wonderfully. There is a rubber strip on the stick to keep it firmly planted. I decided to use Velcro on the rudder pedal end too, just as a back-up, but even if the Velcro lets go, it is fail-safed by trapping the the bracket between the floor and bar on the rudders P.S. The rudder end in these pictures looks loose, its because I took these pictures in the hangar real quick before we left, did not fit the bracket correctly.

Does anybody know if the rudder to control stick distance is the same on the CTLS? I have some other 3D printed parts that I made for Linkage/spar bolts covers in the cabin, For some reason all the holes have different dimensions(slightly, but enough that the covers fit differently), and I wonder due to the large amount of hand layup work, what variation exists between each aircraft. If you have 2 CTLS's, I may want to send you a set of the end pieces, and you could get some tubing that you could verify the length vs. what I used. If I would going to make a batch of these, I think a reasonable way to do it, would be to sell just the end pieces and the end user could purchase and tune their own tubing lengths as well as epoxy/rivet them as needed. Tubing from Menards : $6.99 https://www.menards.com/main/tools-hardware/sheet-metal-rods/hillman-reg-aluminum-round-tubes/11402/tools-hardware/sheet-metal-rods/hillman-reg-aluminum-round-tubes/11397/p-1444432402916.htm Any opinions on that route?

AGLyme Posted March 13, 2019 Report Share Posted March 13, 2019 It isn't long to begin with, meaning it can easily be stowed in the bag. compartment... but... how about developing a bar that folds into itself with a friction lock ? like the snow brush attached here. If you develop a universal, adjustable gust lock, now you have widened your market to include every stick and rudder airplane there is (Kitfox, Bristell, etc, etc.).. you may want to tweak the design to include the Zenith brand of Y stick - which sits in the middle, etc... Ingenious. Link to comment Share on other sites More sharing options...
