Default Sig Something Extra build

From searching the threads from others that have built this plane I have added counterbalancing. What do you think?

Now that I loosely put the tail together I am thinking of extending the trailing edge of the stabilizer to match up to the trailing edge of the fin. It seems that you cut almost all the way through the fin post to make that notch for the elevator joiner wire which to me creates a weak spot. I would much rather cut a small semi-circle on the trailing edge of the fin and another small semi-circle on the leading edge of the rudder.

I loved my Sig Somethin Extra, I had 3. One of the was the ARF version which performed better because it was much lighter than the kit version. Use the wire braces on the tail. I put fiberglass reinforcement on the elevator joiner. I never had a problem with any of my planes. Even after 5+ years, I rebuilt (completely stripped and repaired) the last one and put an OS .55. and increased the throw rates. I beat the living crap out of it and it does just fine.

Here are some updated pics. I do have an issue with the wheels. I turn on one direction and it tightens up. I turn the other wheel the other direction and it tightens up. I am using the stock setup. I did get feedback from Steve Purcifield on how to fix but just haven't had time to get back to it yet.

I never had this kind of landing gear problem. The same set up is used on the Mid star 40 (I had 3) and the Four star 40 (I had 2). Make sure the hex nut and lock nut are tighten against each other. Use a piece of paper and be able to slide it between both washers, if not readjust the locking nuts. This will ensure you have a gap and prevent the wheel from grabbing the hardware. Tighten the two locked nuts against the inboard nut. The screw assy shouldn't rotate at all. The wheel rim may have some friction against the bolt but this will go away in a few landings. Little lock tight goes a long way. Don't tighten the whole assy using the bolt head, you may lose that gap. Let me know if this helps.

I was able to get it taken care of today thanks to you and Steve P.

Any suggestions on how to get CA glue off of the wheel pants? Debonder always seems to make it worse for me. Only thing I can think of is 600 grit sandpaper and maybe above.

Just elbow grease. I buy the little needle tubes to ensure CA goes on properly in tight spots. I have never purchased debonder. My preference is to use Epoxy and some fiberglass inside the wheel pants. CA seems to come apart with the heavy vibration on wheel pants. A thin sheet of fiberglass on the inside seam provides a lot more strength. (I don't ever use CA on Fiberglass either). I land my airplanes very fast too. https://www.youtube.com/watch?v=uLRYOUn5PiQ
I am a product of 80's kits. The airplanes were built like rocks and the engines weren't as powerful. Landing fast was a way to prevent stalls. The Something Extra does land slow and decelerates very quickly. I also fly pusher prop jets and EDF. I like your build, I cant wait to see the covering.

I am not sure of covering design yet. I bought some red and white. I also have an od green like the discontinued Hangar 9 P40B. I guess I didn't post a pic of it but my cockpit floor and seat is red with a white stripe down the middle. I was at least thinking of doing a stripe down the middle of the entire top length to make it look like one continuous stripe along the top. The rest I don't have any thoughts on.

Had a minor but easily repairable setback today. I assume it will need to balanced upside down as I wasn't able to clear the landing gear on the c.g. machine. The setback was I had it on the c.g. machine and it was tail heavy that it fell off and put a hole in one of the wings and broke the end of one of the ailerons. Other than that took a couple days to get all the hardware installed.

Bump on the question regarding if this model needs to be balanced up side down.

I just realized I goofed in that I epoxied the tail section in place without covering it 1st. It'll be a pain to do but I realize I can still cover it.

Lastly I spray painted the wheel pants last night and started to think that it's not fuel proof. Anyone recommend spray on fuel proof clear coat? I have seen some Testors brand clear coat but don't know if it is fuel proof.

I've had a few SSE's and always balanced them right-side-up. Two new pencils, rubber-side-up, sticking out of a board does it for me. As for the clear coat, sorry- no clue

I have a SSE kit in the box, and everything it needs to be built... DuBro gear, Saito FA-62, Rx/servos/battery... Maybe I should get to work heh-heh

Hey! Did you ever get your SSE in the air?

Thanks for asking. I almost had it done. Gluing the canopy is giving me fits. The back plate has a little flex in it and I tried gluing it a couple times but still has a bit of flex. I had the canopy glued in place and when I put it on the plane it was at the wrong angle so I took it off, reglued it and this time I had it on but then moved on me. I was wiping the canopy glue off the canopy again and got debonder on it. So now I am in the process of just spray painting the canopy black with that Top Flite spray paint. Also I had the wheel pants painted with Krylon for Plastic and decided I wanted to put a clear coat on it so I wouldn't have to keep repainting it if fuel got on it eating away the paint. I guess I should have just used the Top Flite spray paint for it too but didn't think about it unti now. Anyway I had one layer of Top Flite Crystal Clear on it, it dried well, put a 2nd coat on it and on one of the pants when I was setting it in place to dry it fell on the ground so I had to remove the clear. In the process it took some paint with it so I have to repaint it. For the other wheel pant I checked it this morning and it has a haze on it. Don't know what happened there and don't know if that can be buffed to a shine or if I also need to remove it and repaint.

I'll post pics in a moment but from the hatch on back I have a white stripe. I am thinking about extending the stripe down a bit further so it looks continuous or just changing the white to red.

Looks like I don't have an updated pic of the bottom after I covered the back part but here it is. What do you think?

Lol! We've all had those builds where the canopy doesn't fit, or the wheel pants get screwed up ....or the cats go into the garage to fight and end up knocking a freshly-covered wing off the table necessitating a repair & re-cover (long story, I really don't know how they survived ).

I like the color scheme, and the control surface mods. I will be doing the same to my next SSE.

What engine/motor do you have in mind?

It's been a while but I believe it's a K&B .55. Any thoughts on the haze for the wheel pant?

BTW if you haven't gone to the Sig website lately, they are advertising limited quantities, preorder SIG Somethin' Extra for $200. They have a red and green version. I like the green version.

Here's one wheel pant done. This is the one that fell to the ground. I put what I think is a thick layer of crystal clear on it yesterday. I think it came out pretty well.

I just checked the box. It's a K&B .45, not .55. Someone in our club had a brand? .46 on his SSE and said it flew really well.

The .45 should do just fine.

Canopy is finally glued on. I also used trim tape to seal it off completely. That little locator dowel on the back of the canopy has been removed too. I glued in a magnet instead and it is holding real well. The other wheel pant is giving me fits still when I try to put on the clear coat. I am going to keep trying to finish it as a side project put don't need them on to fly. I figured if anything I can strip them both back down to plastic and respray with Lustrekoat but I am trying to avoid it. I am trying to finish it the way I am doing it now. On the K&B .45 it says to start with a 10x6 prop. What prop has anyone used with a .45 or similar engine on their SSE?

Well this isn't good when you need a small 2x4 to balance it. The servo tray is notched in so I can't change that. Only thing I can think of is a really heavy battery. The nimh battery that's in there now is all the way forward as far as it can go. The engine has it's own mount that attaches to the back of the engine and the firewall has blind nuts so it's pretty much specific to that engine. Don't know what else I can do.

Wow! Definitely not good. Time to put a Saito .82 in the nose!!

Actually I'm only half joking. I've had 3 SSE's, 2 of these had that Saito motor up front. They were the most fun planes in the history of time itself.
