If I want a 1/6th Cub,Its available from Sig. If I want a 1/5th Cub, its available from Sig,and if I want a 1/4scale Cub,it's available from Sig. Why not others ?
425 inches is the wingspan of the real Cub +/-Couple of inches.

Balsa USA puts out an excellent Cub 1/4 scale and
1/3 scale kit. www.balsausa.com

What about 1/6, or1/5th?

Why does Great Planes,Hangar 9, Goldberg and others ALMOST make scale. There has got to be a reason.

They only make 1/4, 1/3 scale Cub kits. Check out their web site at: www.balsausa.com

They've got to have a fairly large volume and some profit margin to survive.

I have a really neat little L-4 that's closer to scale than anything I've seen in its size range (about 56" span)... but it would never make a successful kit and I doubt it would be very popular as a plan: There's just too much fussy detail for the normal modeler.

I'd love to see more people interested in detailed building, but for a fairly big company, they seem to neeed to aim at the needs of the bigger group which is after easier building if any building at all.

My GP .60 cub (almost finished) is a 1/4.72222222222222222 scale (sort-of). :-)

Goldberg has a .60 sized Cub too....

Has it built well? I would like to find one of these for sale cheap.

The Great Planes fabric covered ARF Cub, they say is 1/5 scale, it is in between the 40+60 size, it is a pretty nice plane. and KOYOSHO maks a 71 inch Cub thats a nice plane, but I don't know about scale,nice ARF.Ken

Ken,
According to my edition of "Janes All The World" the cub has a wingspan of 35ft-5 in.(425 in.) Figure your scale from there.

I think the almost scale models have more to do with optimizing for commonly available balsa stock lengths (36", 42", 48", etc.) and building ease than absolute scale. I've heard of at least one instance where the dimensions of the shipping box determined the final wingspan.

For most sport flyers, 1:47222222222222222 looks just fine at the field.

If you compare the G P cub with the Goldberg cub they are different in size ( 40) . The wings are scaled differently as is the fuse. For true scale one would want to try either Sig or Balsa USA. Both have good scale and Balsa USA aslo has a 1/3 scale that's absolutely awsome! Available as as PA 12 super cub.

I first soloed in a PA12... They are the super cruiser.. The PA-18 is the super cub. If you have ever flown a plane that is exact scale then you would not be asking this question. An exact scale replica flys like crap. Every designer has to trade a few scale lines in order to produce an aircraft that is airworthy.

Also there are many modifications to the full scale aircraft. Clipped wings, longer wings, slotted leading edges etc. There are many options that the designer has to play with and still keep the scale lines.

You know you can get a 1/3 Cub from Balsa USA

Oh. Wait. Someone already siad that!!

I built a J-3 Great planes .60 size kit and I think it is still one of the better J-3 kits available.

I can't say that it's one of the better ones because it's the only one I've built. But I certainly like it. A fellow flyer flys a 1/4 scale cub at my field and it's VERY nice. He doesn't remmeber if it's SIG or Balsa USA or what. My GP 60 flys great. It's my new favorite "relaxed flying" plane - that is - if it's not too windy for me to get it off the ground in one piece. The TT 91 FS is really too much engine for it. There's a photo of it in my gallery. I plan to build a Balsa USA 1/4 scale someday when I have time...

Kevin, how do you keep the aileron servo wires out of the servos in the fuse?

You must also realize that in this hobby, there is "Scale" and "Stand Off Scale".

A "Scale" kit is built to the exact dimentions, using the same building techniques. That is to say, that if the Full Scale plane has 24 ribs, the Scale plane will also have 24 ribs Etc,etc,etc.

A "Stand Off Scale" plane will look like it's Full Scale counterpart from a small distance, but upon close examination, you will see that it may have only 20 ribs (along with many other differences).

The reason being that the smaller version doesn't NEED all of the same things as the Full Scale version. And while the designers are at it, they may also determine that a different airfoil, or different wingspan would suit a smaller plane better.

So they design a plane that will be an easy-to-build, great flying "Model" of a Full Scale Cub.

Mike,

So true. For some craft, an exact scale model would fly terribly.

In order to keep the aileron servo wheres out of the fuse i have them just long enough (taped up excess length) to reach the plugs on the wing and to attach 2 Ernst Security clips to the connections. this prevents the leads from moving enough to tangle in the servos and leaves them long enough to remove the clips and the wing.
