Here is what I made to hold the servos in place for the ailerons. They were made from some aluminum stock purchased from the hardware store. The servos were secured to the brackets using four 2-56 x 3/4" cap head bolts.

Wheels are finally on! These are 4" Sullivan Skylite wheels. Control horns for the ailerons were cut out of some aluminum stock and epoxied between some plywood riblets in the aileron. The holes on the control horn will allow the epoxy to pass between the plywood supports essentially making an epoxy rivet... Du-Bro heavy duty 4-40 ball links along with Hangar 9 Titanium Pro-links make-up the completed assembly...

This is how I drilled my Falcon prop to ready it for the DLE-35RA. I made the base to cradlle the drilling jig out of some scrap oak I had laying around. I used a fractional #61 drill bit to make the holes.

The last four photos show the tail brace wires that I used. I opted not to use the supplied wires in the kit, instead I used Du-Bro's 4-40 tail brace wire kit, they are well made and once installed make the tail rock solid... The first three photos show the Spacewalker on my balancer. The CG was set at 3-3/8" and no additional weight was needed to achieve balance. Of course things may change once it's covered and painted...

The first four photos are showing a minor modification that I incorporated to better support the stringers that are glued to the tops of the formers. If you notice after the second former you will see bracing that I added to further reinforce this area. Once the plane is covered I don't want to hear any cracking sounds from those using a "Kung Fu" grip holding the plane while starting it up. ( Some lesser experienced people tend to use more pressure than needed to hold the plane in this area). The last two photos show how I am keeping track of the parts during tear down.

Outstanding Vincent. Glad to see you are uploading photos. I don't know what the IT guys are doing but it seems like not much. It took me 20 minutes jumping all around trying to get it to keep me logged in.

VJ, I like your balancer. Looks like you made it...and with the same skill as everything you build! I'm interested in building one myself and can reverse engineer from the photos, but could you post a picture of the pivot...that is the most critical part...thanks

Wow VJ! That was a lot of photos you've accumulated. You've done a top notch, fabulously outstanding, superior job there! And it looks like you could drive that thing straight into the ground and not damage it. Sure, maybe a few dents here and there, but..... Dang that looks good! 
(After all that I'm going to complain, sorry. I want better emoticons! The old software was much better there. That's my only complaint.
)
EDIT: Dito that on your balancing mechanism. How about a few photos with a ruler to gauge measurements?

Thanks Robert, Murphey and David. I have been working even though I haven't been able to post. Murphey, you are correct in that my balancer is home made, however I can't take credit for building it. It was made by a fellow flyer at my club. He's very talented and made a bunch of them and sold them for $100.00 a pop. (No, he doesn't have anymore left) It is by far the best balancer I've used and very accurate, and it will hold up to a 50 pound plane! The rod on the end is threaded and is used to balance the scale anytime the CG settings are changed. I hope that these photos will suite your needs...

Vincent, I think we may be related!
I wouldn't change a thing on your build. Looks like you do a lot of things just like I do.
Check out the aileron horns on my Cub, and the servo tray!
(The All-Thread Rod is only temporary, the finished product has Carbon Rod)

This is what I use. Usually my rods are much shorter than the length of rod I get so I will buy one set (rods and ends) then add one set of ends to the order.

Hey VJ,
Your Spacewalker is looking fantastic. Keep up the great work........
Hey Ace,
I have used the same push rods and ends from Central Hobbies for quite a while. They are very nice indeed, but they do take a little extra effort when epoxying the ends on. You need to make sure you have the rod ends secured to the rods while the epoxy dries. If you don't, the air inside the tube may force the end off the rod enough to ruin it. Don't ask me how I know this......
Take care,
David

Nice pics, Vincent !
I think they are getting things fixed, here, albeit too slow for us users. LOL
I started to get email notifications yesterday.
I want to thank Tim, for his help, too.

Thanks Tom. I agree with you things are better than they were a few days ago that's for sure. Ken at RCU had helped me with some difficulties I was having posting photos...Thanks Ken!
I am happy to report that after three days of fun filled sanding it is done! Everything was first sanded with 220 grit paper, that was followed up with a final sanding using 330 grit and it is as smooth as a baby's bottom! Before any covering can start, I now need to clean-up my work area... I will be sure to document the covering process with photos.

Well, Vincent, I hate to say this, but after looking over all of your posts, I have a couple of things that you really must take care of.......
1 - Trim your cuticles.
2 - Ok, I only had one.
Other than that, it appears your work is spotless. Nice job. The control horns are a work of art, and your angle aluminum servo mounts make me wonder why I never thought of that. Lots of great ideas for my SW build, thanks for the pics.......
