Steve's Rudder Trim

[stevesaircraft(Bri)]

FWIW... Thought I would share my approach to setting the 1" preload, and my 'third' hand to help while adjusting the cable tension prior to swaging crimp sleeve. Grabbed a scrap piece of aluminum and fabricated two spacers with AN3 holes spaced 1" apart, connected to the rudder control arm and then to the trim-system cable thimble.
Then was able to use the cable clamp to provide enough tension to keep cable from slipping, while adjusting to remove slack and just slight pressure on the springs... then secured to hold in place while preparing to swage with the nicopress tool.

Bryan...

I use needle nose vise grips with the ends wrapped in electrical tape... Push it against the sleeve, set the pre-load and clamp... I do both sides and then crimp the sleeve's...

Well, Peter asked the big question but I have one also. I've got the Univair conversion with dual toe brakes, will it work okay with those?

Jim

It will work.... Our Pacer has Univair dual brakes... The system taps into the same location where your rudder cables attach to the control horn by way of an AN111 cable bushing. The cables are left long so you install the system, adjust to within 1 inch of the rudder cable attach bolt, crimp on the bushing and trim off the excess cable. The 1 inch gives you your spring tension. So the system will work with Stock, Univair, Williams and any other setup…

It is funny the time this subject has come up.... We are literally right in the middle of an update to the STC. I am upping the cable size to 3/32 and changing the hard to find 1 inch pulleys to MS 24566-1B ball bearing pulleys that are 1.25 inch. With the pulley change, I also have to change two of my brackets slightly.

Now here is the big one…. I spent all morning figuring out my cost on the rudder trim system because we have not done so in over 10 years… Lots of research and digging through old files…I figured out that with the 1 inch pulleys I have a total parts cost of $250.52… With the new pulleys I will have $282.02 into parts. This DOES NOT include my time in assembling the kits and doing the paperwork. With the exception of the engine conversion STC, this one costs me the most to produce. I really need to get at least $400.00 retail each kit to make it somewhat profitable. As it is, I have been loosing money on these for the last 10 years I have been selling them.

As for a group buy.... If you guys are still interested, I can do $340.00 each kit if we can get at least 6 guys into it. That's $60.00 off for those that need a calculator... Sorry Peter L, I can't do 1/3... As you can see, my cost is more than that in the parts and machining... I’ll hold the $340.00 price from now until the end of June.

I will have to have a couple of weeks before I can ship anything due to needing to get the new brackets made and getting enough hardware ordered for the kits.

Time to bring this thread up again. I'm thinking of doing the install during my next annual in the spring, any changes in the offing Brian?

For Steve Pierce, are the pics available or did they get lost in a upgrade of the system??

No changes in the kit.. However, since my old machinist that used to make the parts passed I had to change to a different person... So we are re-evaluating the kit cost... It will be going up, just do not know how much yet...

I am interested in this STC as well. I’m curious as to what the new cost will be.

Which post is missing pictures, I will look and see what I have.

Update,

Have new control wheels, ordered enough pulleys for two kits, need to get a few more items and then I will have the two kits ready in probably a week...

Now, here is the biggie... Priced everything out, the new retail will go up to $525.00... I can do 6 sets at $475.00 for .org members...
