Sig Kougar

All of the older SIG designs had rather high thrust lines which placed the engine quite high in relation to the tank. By mounting the engine at an angle you help lower the carburetor to where it is closer to being in line with the tank. Mounting the engine at an angle also puts the muffler in a more favorable position so that it doesn’t direct the exhaust directly on or near the canopy. You could certainly mount the engine upright and I have seen that done many times. I have also seen engines mounted sideways. There are advantages and disadvantages with each position.

I just finished building one. The nice thing about angled or sideways is you can get the exhaust under the wing and avoid the goo cleanup. I stayed with the angle and put a piece of tubing on the muffler to blow the crap underneath a bit more.

Pretty straight forward build as most Sig kits are. The only changes I made were first to ditch the idea of the stick pushrods and put in solid wire rods in tubes. The elevator isn't that bad with a stick, but with the bend in the wire required for the rudder, too much flex for my tastes. The second thing was I glued a flattened out the leading edge of the ailerons, glued a stiff piece of balsa on and shaped it again. This gave a better fit and stiffened them up a bit as the supplied pieces were pretty soft. I glassed them too Finally, more of an esthetic thing for me, my ailerons don't go to the tips. I added a stationary section about an inch long (red part of tip is stationary)..
Oh... and if you are covering with an iron on film, cover either cover to top of the fuse before installing the ABS top or iron down a narrow strip first. Then you can install the painted top after. IMHO, it just seems to make life a bit easier.
Just wishing for some nice weather now... can't wait to see it in the air.

I've been taking my Kougar to the field every time since finishing it in March. It's the best flying plane I own. Durafly Tundra, Freewing F-104 70mm, Ugly Stik, J3 Cub, etc....all great but the Kougar is IMO a fun blend of speed, stability, and smooth pattern-like manuevering. The nose high landings never get old!
I agree with the above posters. Angle the engine and use a tip to further blow the oil below the wing. Makes cleanup a piece of cake.

Ya, I had the itch for a Kougar after seeing one at the field. I had its little brother a Kobra years ago and that plane was fun as hell. The Kobra was the same way on landing, nose high... I remembered to put a nylon skid on the tail of this one LOL.
Here's a bottom shot of mine.... damn checkerboard looks nice, but takes forever to do.

Thanks to everyone for the advice... I'm building after 40 years hiatus with my 10 year old son and we are having a blast. I've flown a lot- but always was short of time and had friends who like to build do the building. Currently have a scratch built Miles Reed Week's Solution and a Dave Patrick Ultimate Bipe in the hangar. My son soloed on Sensei and wanted to build so here we are with the Kougar and it's going well. Painting this one- always Monokote in past but ordered some Klass Kote and a sprayer. We'll see how it goes. Thanks again!

I had one that I bought as a kit from a guy about 12 years ago, the kit still had the sticker on it from tower hobbies in 1970 something....loved that airplane, I still have the wing panel, but unfortunately someone cut the lock of my aircraft trailer and stole the fuselage along with two other fuses and all my tools and my DX18 transmitter and charging equipment....oh well, what'd ya gonna do???....sit and cry about it all the time?...Oh yea I could do that, but I'd rather bounce back and prove to myself that this loser isn't gonna ruin the hobby for me....
That being made perfectly clear...….the parts to build a new Kougar fuse arrived yesterday, and I pick up a nearly brand new Spektrum DX20 at the post office today :-)

Kirk, I built my Kougar with a balsa sheet turtle deck instead of the plastic top. It’s 1/16 thick wetted with water and taped over the plastic one to shape it.

The Kougar was my first first ever Sig kit and I remember every minute of that build . I was so excited to have a non trainer plane to build and fly . The Kougar build gave me the building bug for sure. I soon after went on to much bigger builds from there. I've scratch and plans built over a hundred planes of all sizes and types and the Kougar is among my favorites.

I've only done an initial break in run and tune on the ground so far and ya, seems like there should be power to spare to haul it around nicely. Saturday forecast has gone to crap, hoping Sunday holds out as I have to maiden both a Komander and the Kougar.

Mine flew very well on a Magnum 46xl and even beter on a Magnum 53xl. If you already have a 46 there is no reason not to use it .
