Yes the 4*54 is a clipped wing but it sure flies good. I got one of the first ones that came out. I have an electric in mine

acdii 02-10-2014 12:40 PM

So what would a clipped wing 120 be? Thats what I have, shortened it by one bay per panel. Wishing I had some skis for it so I can at least try to fly it, but its still too freaking cold to be out for more than a few minutes.

I hear ya brother, we were planning a Snow Fly on Sunday but its just too darn cold.

gosch 02-10-2014 02:24 PM

I am not sure what it would be called (LOL) probably a clipped wing 120.

skylark-flier 02-10-2014 04:57 PM

Might one call it a "Bay Short"?

I will stay out of the name business but suggest floats less the water rudder as a substitute for skis.

Bay Short sounds...rated.

Short and singing about sums it up.

Yeah, I know. Best I could do without coffee "in hand".

Good looking Cougar US185 Damiani! Sign this boy up!

Sig Rascal 40 ARF, the old one, I've had it for 7 years. Still flies great.

I had a Sig 4* 40 and lasted me only 2 years due to a tree getting in the way.:(

Ok, calling all Sig Brothers!!!! I just got off the phone with Sig Brother #37, Mike Gretz, with an idea that I have. We all know that the Annual Toledo show is coming up. So what we would like to do is try to see how many of the Sig Brotherhood will be attending the Toledo show this year and if we can come up with a time for all of us to meet at the Sig Booth. We want to get together for a "Family Portrait" so show our Sig Pride. Mike thinks it's a great idea and I do too. I've loved Sig and their planes for as long as I've been in this hobby, so I really want to see if we can pull this together and get a good showing for them. At the very least we'll shoot a group photo of the Sig Brotherhood and post it up in the Toledo Coverage, but I'm also thinking that if we can get enough people show up I have a really good idea for a "Sig Brotherhood Vidoe". Here's my idea of what we'll do. Everybody show up for the group picture and then I'll set up the video camera and everybody that's a Sig brother take turns on the video camera and state name, sig brother number, and their Sig planes they've owned. I'll all have my PM you can send me pictures of your planes before or after Toledo and once we're all back I'll edit out the piece and make the "1st Annual Toledo Sig Brotherhood Video"

What do you all think???? can we get enough Sig Brothers there to pull this off????

Ken, that's a great idea! Count me in. Keith

Nice! I love Kougar's too. Looks like you got your money's worth out of that one.

hsukaria 02-11-2014 05:43 PM

Hi Ken, I will be at the Toledo show too, on Saturday.

How can you tell? It looks ready to fly to me.

The absolute best view of a Kougar I have ever had (and I went through 21 of them) was just after take off. Wing tip 6 inches from the ground in a 90 degree bank and pulling around for the touch and go. Used to be able to tell if I over banked because it would loose altitude. Fun fun fun airframes.

Not at all sure I can do Toledo this year..lemme see...

jeffie8696 02-11-2014 06:24 PM

I might actually be able to swing it.

Looks like it's seen years of service. Not saying it's no longer flying, just can tell it's been thoroughly flown.

Yeah, these Kougars are absolutely stunning when taking off or coming in. The first time I saw one of these was back in '81, there were two guys who where actual heli mechanics used to fly them. These Kougars were so cool that I had to get one for myself. I've had four in total since then.

Ok, this might be a good time for me to ask this question (maybe should be in a different area?). I am looking for a new home for my engine (Fox 74), would I get the Kougar or the King Kobra? I can see that the King Kobra is bigger, but any other differences? I want to try out pattern flying.

I've never built a King Kobra before, but I'd say that would be the better bird for it since the Kougar is smaller. One thing to also seriously consider is the prop clearance. With my Kougar, I've got a OS Max .65 which takes 13" props. However with that prop, there is only 1/2 inch of clearance. I've got a 11x8 prop on it now and get about an inch and a half to two inches of clearance, still not enough to take off/land on grass or dirt, but I've got pave runway to operate on.

Overall, I'd say the Kobra and Kougar are virtually the same, just difference in size and a little in regards to the streamline. The Kobra looks a little bit more streamlined compared to the Kougar. So they are probably exact in regards to the build process. Another thing to consider too is that the Kougar can only take so much engine. I'm really pushing it with the .65, the bird was designed for a .40 - .50. The three Kougars I had built previously had only .61's in them and that was more than enough beans to get the job done. The very first one I build in the summer of '81 had a K & B .61 with a fuel pump. I didn't know a lick about any of that but was just duplicating what the heli mechanic guys had in their Kougars. Those birds were rockets and I loved how they would come in smoking hot but land flawlessly. Gee, makes me want Saturday to be here right now so I can get my Kougar out! :)

Hope that helps.

The Kougar Mark II is a good choice if you are new to Pattern flying according to the SIG website.

Would the power plant that he's planning to built it with make a difference? Kougar is a great pattern bird but very size restraining in regards to size of prop it can run. If operating from a grass/dirt field, I'd have to say a good three inches of clearance would be ideal. I'm not familiar with a Fox 74 so I don't know what props those operate with. I'd say if you got the prop clearance, why not do a Kougar.

Another thing I've had to deal with is fuel tank size. Since I've got a .65 in mine, a 12 oz tank is very tight in that bird. Very limited space for larger fuel tanks too. I needed a shoe horn to get everything installed in mine. And with a larger, more powerful power plant, there was a little bit of structure enhancements that needed to be done. Again, the Kougar was designed 30+ years ago and for .40 to .50 sized engines. Installing modern and larger power plants with greater power output does requires the bird to be built accordingly.

hsukaria 02-12-2014 01:48 PM

I would be using a 12 or possibly 13 inch prop. But your mentioning the fuel tank cramming and beefing up things, maybe the Kobra would be better for the bigger engine. Thanks.

Yeah on the Kougar if you build it with the factory fixed landing gear, a 12" and 13" prop is almost too big even on paved runway, grass and/or dirt forget it. On the bench I was running 13" props in my Kougar during tuning of the Mac's tuned pipe. But I soon realized that there was only half a inch of clearance between the prop and the table top. This is why I settled with the 11x7 and 11x8 props. I only fly off and on paved runways too.

I've never built a King Kobra so I really don't know what the difference is in regards to fuselage size differences between that and the Kougar. May only be the wing, I don't know. I would be willing to bet that the fuse is basically the same size in that area on both the birds.

Another alternative perhaps could be a three bladed prop. If you go with one of those, you can get away with a bit of a smaller diameter prop. Not sure how much smaller, but that is an option perhaps.
