Well, This is my first post on classic pattern flying and RCU, first, I want to say what a good site you have.
Now for my question, there is a SIG Kobra sitting in the hobby store.(it has been there for a while) i hope i am in the right place for this. so:
1. Is this a rare kit?
2. Is it worth building?
3. How does it fly/go?

BTW: The hobby shop is leaving to another state, and this is my last chance at this kind of plane.

Thanks.

No. Sig still produces them.

Absolutely!

Terrific. Its smaller and faster than its bigger brothers
the Kougar and King Kobra. With a strong motor its a
rocket ship.

One note...the Kobra has a built up wing while the Kougar
and King Kobra have foam core wings.

Get it.

Thanks, if i stuck an O.S .32 in it would that be a good idea, or should i put an O.S 25 FP in it. The .32 is in another plane, so would the KOBRA be underpowered with the .25? The FP has been run twice so reliability and performance of a crusty old motor are NOT a factor.
so now the question is .32 or .25. What do you people think?[sm=confused.gif]

You still get kits at your LHS? there is only one store here that still sells kits often, and they are leaving.
the other two stores only stock ARF, ARC and RTF really.l Maybe I can order things in.

It is an ugly predicament I'm in isnt it?

I had a Sig Kobra and LOVED it. I flew mine with a Evolution 36 and 9x7 prop. It screamed! Get the Kobra, you won't be sorry. I went with the Evolution because it is a powerful, inexpensive, light engine that fit very well in the plane. If you don't mind shelling out the insane price for the OS 32sx, go for it. I'm sure it would be an excellent power plant for that plane but there are other engines out there that cost less and still perform well. Either way, it's a really fun plane!

We no longer have a LHS in our area. So everything is by mail order.
However I live only about 90 miles from Tower. So I can get stuff
from them quickly. Although their inventory of kits is shrinking rapidly.

It most certainly is. Especially for someone like me that does
NOT and will NOT buy ARFs.

Go with the 32. The Kobra was meant to fly FAST. Give it
the muscle it needs.

Awwwwwwwwwwwwwwwwwwwwwwww Stick a Jett 60 LX in the thing and be done with it. Wanna go faster, add retracts. Will be a while before you want anything faster, so your saving money in the long run? Rev brother 119

I think a hot 46 or a 50 would do the trick right nice. LOL

Then again with that much speed one may loose track of it, crash and burn in a matter of minutes.

But he probably won't want anything faster.

Just think, you could cover it day glo orange and have a bright orange streak go across the sky...

Hey Sonic500:

I've had 3 Kobras over the years; the first two I had Enya 45CX's in the nose really fast. The last Kobra I put an OS32SX in the nose with a tuned pipe.
Whooooooooooooooooooooooooooooo!!!!!!!!!!!

kf

Well, I have all ready shelled out the price for a .32 SX so i might as well drop her in,
Anyways, i got the kit today for $120 AU (same price as a Vmar trainer) after a bit of haggling. It was made in 1982 and packed by a person called Connie, well after looking at it and its thick wing and (fairly wide fuzz) i decided to put the .32 in it.
Bye Bye Sonic oh well, i lost every race anyway my only problem is that the sonic is actually a nice plane with a light motor, I still have to finish an Electra anyway and THEN start Kobra [:'(]

EDIT: 1. How shall I cover this ?
2.Does a Macs pipe sound nice to you

That plane should scream with a 32sx and a pipe! I would cover in film to keep it light. I use Sig Aerokote. It seems to hold up very well.

Heat shrink film for covering, I'll try hard to make this look nice, my undoing is always on the wing tips.

Kamakazie Frank, You put .45's in it?. I thought all materials spontaneously combust at a certain temperture
what pipe did you use on the SX? Was it the Macs pipe?

Mmattockx:
Your idea sounds somewhat 'interesting', but at those speeds it is more likely to be a great orange hole in the ground and BTW nice name, Mark.

Mark# 2[8D]

Don't worry, wingtips are cake! Get a copy of Faye Stilley's book Covering RC Airplanes (think that's the title). He explains the logic behind successful covering, including wingtips, very effectively. I used to have a problem with wingtips too until I read his book.

I tooput a .46 in the nose of one I built some years ago. It was wicked fast, but flew relatively poor, compaired to having a royal .32 in it. The Royal was much lighter, thus the plane flew much better. Unfortunately lost it due to interference upon approach. But I built another, I will post a pic or 2 later.

Hey Sonic:

You have a perfect match for the Kobra. The 32SX is a great engine coupled with a Macs tuned pipe.

The Kobra's with the 45CX's were fast but made it difficult to handle because of the additional weight. Good luck with your project.

kf

Thats sort-of what I want, A plane that goes fast but CAN actually glide in out of the sky dead engine, so will this thing be faster than my SONIC 500.

If you have looked at my details you will find that I am young (compared to you lot) and I have little experience building kits, so far this will be the most complicated, so this is my 3rd kit model (RC). I worked from a FF chuck glider to a small 2 channel RC glider to a CG Electra now to this, so if you wish me luck it's much needed -I need it-

'Markus'

EDIT; I might be young, but my Dad always expalained how slick 'his old Curare' was at any chance :thumbsup:
at the moment it is sitting in one of his friends garages in Adelaide, unbroken, unused and lonely, prob is that Adelaid is 4 hours away by 737 []

Edited to fix my wording

Make no mistake about it, the Kobra is NOT going to fly anything like a "lightly loaded trainer". The plane builds fairly heavy, thus the wing loading is high as is the landing speed. That is not to say it's hard to fly. To the contrary, it is remarkably stable! It just will not float or slow down like a trainer (or most other sport planes for that matter). It has great wind penetration characteristics... what does that tell you? It really is a great airplane. ...kinda starting to want another one now...

Brian

Oops [sm=red_smile.gif]- should have checked my facts before posting, what I really meant was something that does not drop out of the sky like a brick as soon as the engine stops like my Combat ninja,

I watched Rainedave's Tippo (I think it was his) on the BPA thread, that was fast, is this going to be a slightly more mild experience than the Tipporare, or is this thing faster than I betted on.

Brian, is this thing faster than a Q500 with a .46, I can take faster, I would just like to know what I am in for in the next few months [8D]

If I have the chance to regain possesion of the Curare should I take it?

Don't know, never flown a Q-500.

Here is a shot of my Kobra. Covered with Sig Coverall and dope. I currently have a GMS .32 engine in it, but have not flown it with it. I think it weigths somewhere around 3.5 pounds dry.

A friend gave me a kit of one before he moved. It needed another wing so I got a wing kit. Shoehorned a ST 40 in him; I think it had the same footprint as an OS 35fp, so why not? He was fast but also a great smooth flier, but he died to soon.

-----------------


It isn't really a pattern ship, if that means anything to you.

There was a time when having a pattern ship was considered "cool", soooo, the manufacturers began calling any low winged model a pattern ship. The Sig line of low wing models were all dubbed pattern ships by the marketing folks, even though not a single one of them was a true pattern ship. How to spot a pseudo patternship? If the bottom of the rudder is above the horizontal centerline of the wing, it's not really a pattern ship.

I'm not saying that it is a bad sport model. It is good at sport flying. Lots of people enjoyed them over the years. But it doesn't come close to handling like a real pattern ship.
