So, been looking around for a winter build and think I have it narrowed down to a Cub. What I have is an OS 70 FS that will work well in a Great Planes ARF cub, but I wont to built one from a kit.

Narrowed it down to a SIG, either the 1/5th scale or 1/4 scale. Difference of $4 between the two. The 1/4 is $4 more, but can be built either full or clipped wing. So which of the 2 is a better kit?

If you go with #1 you will need to buy an engine, your 70 will work on #2

Thats what I was thinking too, and it could be built as a clipped wing version from the same kit.

How does Great Planes Cub compare to the SIG? The 1/5th is laser cut and looks to be a good kit as were the other Sig planes I built, but not familiar with GP. I know they now own what used to be Carl Goldberg and I have built their Cub and building a Chipmunk now, but these were original CG kits.

Currently building the carl goldberg piper cub, it's ,my first build it's going smooth!! Very easy!

Ordered the SIG 1/5th Cub and 5 yards of Koverall this afternoon, and should have it by Thursday. I also picked up 10 JR standard servos for $5 each brand new. Need to take an inventory now and swap out higher end servos where they are not needed with these new servos and use those in the Warbirds I am building. These $5 servos will work very well for flaps and trainers. They are equivalent to Futaba 3004.

I have built a couple of the GP and Sig Cubs. They all fly the same but the Sig is built like a tank. Both are very easy builds but the 70 is a good engine for the smaller Cubs. As I recall the GP Cub was a 72 inch wing and I stuck an OS 70fs in it, way too much engine, well, more then a Cub requires. Last one I built was the Sig anniversary Cub but I stuck an OS 91fs in it. Again, way lots of engine but it was all the owner had on hand and it was a float plane. Also needed the added weight for the CG. I like the Sig kits. Tough call but at least you have the right engine on hand for the smaller one.

My flying buddy had the great planes fabric covered ARF and flew it with this same engine, and it flew great, the wingspan is right about the same as this kit, and the fact its all laser cut is a plus. I really enjoyed the LT40 and 4*120 kits, and looking forward to this next one. The only decision left is to decide if it will be a J3, J4 or clipped wing.

I personally would go with the Sig 1/4 scale Cub . It is a great build and Fantastic flying plane . I am flying one now and I take it to the field almost every time out . It assembles easily ..I like the full size wing . The bigger they are the better they fly . The 1/4 Scale Sig Cub is one of the nicest flying planes . I would put Robart gear on it though .

I would have to buy an engine for it though, which is why I went with the 1/5th since what I have is perfect for it. Besides, if I did go 1.4 scale it would HAVE to have a 4 stroke twin on it. I just dont have that kind of cash for one. Nothing would look or sound sweeter than a 4 stroke twin on a cub, except maybe a 4 stroke quad.

good choice… sig cub's are all great flyers. My favorite was a 1/4 scale clipped wing.

Well I started working on the Cub, and that SIG kit is great!!! Almost done with the Fuse, at the point where the elevator pushrod is installed and ran into the same problem I have with my LT40, the inner pushrod is a tad tight. Going to replace the kit one with a Gold-n-rod. The rudder is a pull-pull cable setup and this will be my third one, really like doing the rudder this way, wish I could do it with my Corsair and P-51.

It builds very well, and I am amazed at how light it is so far, I think the landing gear will weigh more than the entire fuse. I did glue the lower door together backwards though, oops, Easy fix, I sliced off the top part and glued it back on so it matches the plans. I somehow got the pieces reversed when I set them down.

While I am building mine, my friend is rebuilding his GP ARF that visited a local tree a couple years back. He has the wing back together, and most of the fuse done. They are both about the same size, the SIG being more accurate to scale though, but his cowl looks more like a Cub than the SIG one does.

Glad I went with the SIG kit, just confirms my belief that SIG makes some damned good kits. This is my third one. My other two are Top Flite Warbirds, Not nearly as good as the SIG kits.

Don't confuse the build method, on your 1/5 Cub, to that of the Sig Crafstman Series kits.

The Crafstman Series kits are great, but the level of complexity increases tremendously. Your kit is more a kin of the Four Star type. The Craftsman Series kits are more stick and twig. They have parts that are just printed on balsa, and must be cut by the builder..

That I know, it is one step above a plans build in that the parts are printed for you on stock. Plans build is where you supply the stock and layout the parts yourself. For the average builder, the SIG kits are very well laid out, and that is what I like about them. The only thing I came across that could be improved upon is a note saying which piece of stick to use for what. There was a step in the build where it called for a stick of a particular type, but the kit includes several of that size in various lengths without a designation for what, so I had to go through all the steps in the manual to find out what went where. That size part was used in both the fuse and the wing.

the next plane after I finish this one is a copy of the Pica P-40. WE have one kit and we plan to make 3 planes from the plans and manual. When we finish that, then we move onto a scratch build of a B-17E.

Acdii you can't lose with the Sig kit. They build nice and lite.


Tom, I remember back in the early 90's I built my first 1/4 scale clipped wing cub. I used a coping saw to
cut out all the inked parts. My hand looked like Fred Sanford's after he got an attack of arthritis. Needless to
say I baught a scrolll saw for the next one.

Ya, those Sig Crafstmen Series kits are a bit of work. I use a bandsaw to cut the printed parts. I eyeball the sticks and twigs, though, using my razor saw.

"Next one" ? Good man ! I'm glad that you didn't stop after the first one. I didn't either. I like the challenge. They're more fun, than the jig lock construction of modern kits.

I was considering the 1/4 scale stick built Sig Cub, but I would need a new motor for it, and the whole point was a kit to match what I had.

So far the fuse is done, and the stab and elevator glued up. Ready to sand and put the joiner in. What is interesting is I didnt realize it came with the throttle cable, so I have a spare now. It routes nicely under the door and out of the way. Still deciding on what color scheme I want to do. Maybe a nice red,white and blue like my Kadet, but painted not Kote. So far it is building so light that OS 70 will make it hover! Going to do some research on the interior and see if I can make up a cabin for it.

If he got the 1/5th Scale Sig Kit he has one of the best kits I have ever had the pleasure to build. It is a modern design and basically falls together. The 1/5th Scale is all laser cut. I built mine years ago and it is one of my best flying Cubs, I have three.

SunDevilPilot

sig 1/4 and the new rcgf 30 twin 7" cap to cap just sent away to get one for my 1/4 sig cub.

Thats the one I got. Just ordered a wing kit for it so I can build a clipped wing version along with the full wing. One plane, two wing sets. I can then decide which one I like to fly most. Painting it red whit and blue too, just haven't come up with a pattern yet, but it will be nice and unique.

Check out s****.com, they have a pretty red,white,and blue cub on their website. Also
the Goldberg ARF cub was red, white,& blue and it looked pretty sweet.

that's s****.com

Something tells me its not going to post LOL

I just had a thought, who says I cant paint it like the Super Chipmunk? That should look pretty damned cool!

For some reason it don't want me using the word s****

That Chipmunk scheme would look nice.

Try to pull up Mariano Alfafara's cub it looks real good.
