Status: offline 		Frank, I hope these two photos will help. I can't claim the idea was original! I have the large Funtana from Hangar 9, and this was how they did the strengthening of its stab. I FORGOT TO MAKE THE IMAGES SMALLER! I'LL REPOST IN A FEW MIN!

One could use the metal rods, clevises, etc; but I had an extra length of carbon rod laying around, so that was used. Just drilled the holes and epoxy. I also sealed the hinge line on the bottom. I doubt if that was necessary. Only two flights on the SS, it performs beautifly. The Fuji 32 provides plenty of power for all manuvers, except 3D, of course. Only had to add 6 oz of weight to the tail to offset the heavy Fuji. About 2 oz was added to the servo area to balance laterally.

Best of luck with yours, I am sure you'll love it!

Gary

Yes, that was all! Most difficult part is drilling the stab at the correct angle. I just started with a very small drill bit and ran a scrap length of a 2-56 threaded rod down to the fuse and "adjusted" the angle a little bit at a time until I got it "right". Just epoxyied them in and smoothed the top of the stab, then applied a little patch of monokote over the area.

If you look a page or two back in the thread, you will see that someone ha a massive horizontal stab failure due to flutter. I believe that's the reasoning behind it.

Setting up the new sportster. Looks like inner most hole on the servo and outer most hole on control horn gives me the high rate of 1 1/2 inches at 100%. I believe that was the guidence you were giving, but wanted to make sure. Looks sorta funny to me with the pushrod on that inside hole on the servo arm, but the math makes sense. I have sealed all the hinge lines, counter balanced the elevators, and plan to add flying wires this afternoon. I tried some 2x4 bracing but all I had was pressure treated and that was a bit too heavy.

You have it right. As "smokingwreckage" said above, you can improve the situation a bit more and also make it look more normal by using a longer horn on the elevators. Then you can move the pushrod out a hole or two on the servo arm and still use 100% EPA.

But what you have now is the best you can do with the horns you have.

Status: offline 		Has anyone put a Brillelli 40 into this plane yet? My 40 just arrived today and I'm wondering if it's going to fit without opening up the cowl for the muffler. I'd really hate to do that, but I've got the engine and if I have not choice, well, so be it. But I'd like to hear from anyone that has actually mounted this engine on the SS.

Thanks

Status: offline 		I have one on order and I am going to install a Brillelli 40GT for power. This engine is 8 oz lighter than the Fuji 32 that is suggested and produces more power. I plan on starting the build in a couple of weeks and I will post it here on RC Universe. With almost 1300sq in wing area and a 40GT gasser for power this plane will be a ball to fly.

Status: offline 		Be prepared to do a LOT of cowl cutting with the Brillelli 40. I just finished mine and it seems that rear-port engines work better for this plane. With the Brillelli and Futaba 3010's it required about 6oz of lead on the nose plus having the receiver battery up front. I think it would have taken about a pound if I left the receiver battery where it was.

Maidened it today and it flew very nicely with very little trimming necessary. Site below has some build pics but I forgot the camera today, so I'll probably have some finshed and flying pics tomorrow and maybe some video.
