The pictures below show the steps I used for the wing brace as well as a comparison of the carbon fiber vs fiberglass rods.

Here is a good source for the carbon fiber tubes:

Just by chance I ordered 4 wrong size "Carbon Fiber Tubes" .196" OD x .121" ID x 24". What I found was if I cut the 2 shorter kit provided fiberglass rods in half (giving me 4 rods) they fit exactly into the metal angled pieces AND the new CFR's snugly. I just rolled the ends of the cut fiberglass rods in GGlue and pushed them all together. I must say it looks factory made.

CFR's purchased from OmniModels.com $4.79/ea

Dave, do you think I can use GGlue instead of the epoxy?

ya, GG is another alternative. Were the tubes I mentioned the wrong size?

The link you have posted sent me to the size I purchased but they did not slip over the metal tube, they were the same OD & ID. I like it better, no thread, looks clean...You did me a favor as I did not have any thread HA-Ha-ha...

I also got the Depron but they only had 3mm so I GG'ed two sheets together. I will cut them tomorrow using the great templets you posted...Denny

I see where I went wrong....

The OD is .196 - I should have referenced the ID should be .196.

So what your saying is that this will work out OK? Does it feel quite strong?

My bad. I'll edit that post and reference yours for an alternative.

Sorry about that and also I am glad that it worked out. Keep us posted on your progress

I think it is an improvement on the build and you get the credit!!! The fit is tight all the way around and as soon as the GG swells a bit it should be tighter than a 1/2 inch dowel in a 1/4 inch round hole.

Default Weight

I finally weighed the SS and here are the results:

(I have a 3 cell 2200 mah Lipo, you could go smaller if you want to lighten up)

My camera weighs 4.3 oz w/ batteries. You will have to add the weight of your own camera to this for final AUW.

* No camera is included in the weight below *


Weight With Camera Mount: 30.4 oz



Weight Without Camera Mount: 26.4 oz

Well the wings are Fiber taped with carbon rods, alot of guys fly their SS stock which works, but an emergengy high-G turn and they will most likely fold with the camera weight resting at the CG. When I fly AP I take off near vertical and land almost the same given the surroundings. I cant afford to have a wing failure with several hundred dollars riding beneath it.

The positive thing to remember is that the weight helps the airplane penetrate wind better than a lighter model. With that much wing area the wing loading is still minimal.

Yep, a strong wing = priceless for AP!
I don't have a scale but I'd say our SS's are about the same weight. It moves right on out compared to a stock version! It'll be even worse when I add two more Futaba servos and the new receiver (Tower finally got off their keister and they arrived today).

I got the backend parts cut out last night from the 6mm Dupron and glued the CFR's to the wings. Just adding the rods the wings are really stable. I did have options on rod placement for the front of the wings. I could have placed them along the bottom of the wing but they seem to fit better as sort of a bumper on the top front edge. I don't know if it will hamper the flight but it sure will stop any front edge wing damage. For the back I fit the rods under the edge. All glued now just a bit of tape and they should be complete.

I had ordered the #EFL2255 Landing Gear:Mini UltraSt (Aluminum) because the CF ones are back ordered. They have a 12" width but are very light and the wheels come included, nice soft rubber ones. As I get along I will post some pictures.

Actually, the SS has no trouble with extra weight. It makes it penetrate the wind better and seems to fly a little smoother. Of course, it's not made to carry 3 or 4 bricks, but it hauls plenty of weight especially when it's beefed up with braces. It is one of the great all time planes!

Default SS mods

So with the extra weight with the camera and everything. A outrunner that runs about 30 oz of thrust with an 11 inch prop should work well and bring the ss up a good altitude? What kind of outrunners are you guys using. I was looking at the 400xt.

Justin - i will post my pics from my build as i start gathering parts.

I was also thinking about using the elevator and making a covered rudder from my brio 10 setup that i crashed (not a good first plane) rudder and elevator are about the same size as the stock SS. Tell me what you all think.

Dave, Ok' I have the new horiz stab pieces cut, the rod along the trailing edge is for what? How is the hinge made and how did you connect the 2 up down flaps together?

It looks like a rod was notched in and glued maybe. Also the hindge for the verticle stab (probable the same method as the horiz one).

I'm using this link for my build: http://www.ampaviators.com/articlessos/index03.htm
Not using all of it but most...Denny

Justin,

I think your right on target with the motor, the one I picked is about the same power. As for the tail, I say go for it. Its already made and might make it look cooler!

oh yea, make sure your lipo and esc can support the motors need for juice.

ahh Denny, your showing the parts I skipped...lol

I used clear packing tape for the hinge. You can pick it up at wallyworld for a couple bucks. I beveled the edge of the moving surface (~45 degrees) and taped one side of it. For the elevator, I used a round dowel to connect the left and right side. If you can wait until tomorow evening, I will post good pictures showing this.

Dont forget to add the Carbon fiber strip along the back of the horizontal stab...

I have my SS with an aluminum Fuse and now im trying to get another SS the new one with fiberglass for my extreme build. Damn these planes are hard to find with availability. Looking for a yellow one.. hopefully i can match the scheme with my covered tail and rudder.

Default Snow is melting here in Iowa

The snow should be gone by today or tomorrow. I am planning on a flight(s) with the slowstick and will have some inflight video of it as well.

I believe spring is starting to emerge.....finally!
