Flight control assemblies

Yep that's basically what I have found so far. Thanks for the info! For anyone that hasn't already found out, Aircraft Tool Supply has the reamer for $30 which is considerably cheaper than ACS.

Ordering now...

You are very welcome. This is why we have worked so hard to build the Sonex Builders and Pilots Foundation - so we can all share this kind of information. We all can work to make the community grow, but we need everyone's help to add more content just like this.

Okay all,

I'm currently working on the control assembly and Waiex mixer. I've installed the 5/8" ID x 3/4" OD bushings in the control tree and have removed the powder coating from the control horns (SNX-C04-08). However, I still cannot push in the control horn due to a really tight fit. The plans say to line ream the bushings to obtain a "snug but freely rotating fit."

Any suggestions on what to use to line ream these bushings? I don't think they will need much, but it's a small enough diameter that it is hard to get sandpaper inside to ream them evenly.

Eric,
Sorry for being 30 months late on the answer. I used a piece of 5/8" stock that was a little smaller than the weldment. Some Nuvite F9 used as lapping compound did the trick nicely. First on the stock, next on the weldment. Worked great!


On my project thread Robbie mentioned taper pins and that search brought me here. So I am wondering if I should put taper pins in my sticks. My fit is nice right now.

142YX, I wish your pictures were still up.

Hi Bryan,
Are u sure they are snug, the sticks with an bolts in them? Thats what i thought, and everything snugged up . Then wiggle them! Whoa! Wait a minute! Sloppy sticks. Get some taper pins , acs, and there is special washers also to go along with castle nuts an cotter pins. Yep not cheap. Got to buy tapered reamers too, a few cause not sure which one i needed. Omg the tool box is filling up!
Cant wait to see u fly! All this will make your smile even wider. Great job with adam.

Also, not sure where N142YX went. I dont think on these boards any more . I saw him at the KMHV fly in a couple months ago ( had some interesting mods on his green machine waiex. Was running the bing carb , he gave up on a couple different tbi's, i mentioned hacman for his bing (green sky adventures?)for mixture control. Running a bigger spinner from jabiriu, and dual jabiriu muffler exhausts. I think they may keep him busy at scaled composites out in mojave.

I have the reamer required for the taper pins, Bryan.

What size is the reamer ? I need to replace a 1/4 bolt not a new build.

I used a # 2 B&S reamer for the #2 taper pin, to replace that 1/4" bolt.

Somebody earlier in another thread viewtopic.php?f=21&p=29368#p29368 said you can use a #1 reamer for a #2 pin?

I am finishing the connections to my mixer and have an issue with the Idler to Mixer pushrod. I bent the washers on the Ruddervator pushrods per the thread here. That resolved the conflict on those but now the nut on mixer push rod is contacting the Ruddervator rods when right rudder is applied. There are two sets of holes in the mixer assembly and the plans show using only the inner set of holes. Has anyone had/resolved this problem or alternately used the outboard set of holes ?
