Which Cub
 
Getting ready to purchase a Cub, probably a kit. Trying to decide between the GP 40 size and the Sig 1/5 size. Have read the Sig one is a great kit, great flyer, less expensive but not designed for "durability". On the other hand the GP is a more durable design but tends to resemble a lead sled in flight. Can anyone who has actually built and flown either of these give me there thoughts on them
Thanks
Roger

Roger,
After MANY hrs of reading, searching forums and asking everyone who ever flew a model airplane for opinions on cubs, Ive come to a certain conclusion, It just doesnt matter. If you ask 5 people you WILL get 5 different answers.
One common I did get was to stay away from Nosens unless you really want to get into reinginering.
Great Planes AND Sig make a great kit, unless you make changes yourself, I believe youll end up with basically the same airplane which will fly wonderfully.
Im building the Sig clipped 1/4 scale cub (when it comes in) I guess mainly because Ive built 4 Sigs already (not cubs) and feel like I kind of know what to expect.
Your a modeler, youll enjoy building it, now, go get it and have fun!
Roger

ps
I dont mean to imply that Im not truely gratefull for all the feedback that so many folks have given me here, in fact, its given me the confidence I needed to make a choice that I know Ill be happy with.

Well I did build the Sig 1/5th scale kit this year and I think Sig has taken Laser cutting and kit?Cad design to a Higher level!.
I have buillt several Kits form "stick built" to then new laser cut designs like a 4* 60.
I realy enjoy the old style building best cus the laser stuff goes together too fast for me most times. ( read runnig outa space).
When I started building the Sig Cub I found that I could not stop
building Just to see how they were going to the next step.

It is almost ALL balsa very very little "liteply" you do have some old style things in the kit like soldering the landing gear.
The plug in wings are very nice ,but you do have to carve the wing struts which are Functional..
I did several scale add ons so I can't comment on how a stock one will fly.
I used a Saito 90TS twin with an onboard glow setup and Robart scale gear so it is a little heavy.
That being said it still is a gentle flyer BUT with mine you need to use rudder with all turns or it give some pretty strong advesre yaw.

As for the Fragile part well it is light and I wouldn't consider it for an every day work horse kinda plane but it will hold up well

I loved the kit

Hope this helps a little

Roger,
I just took possession of my GP 40 sized cub, and it looks GREAT! I can't wait to start. I enjoy the GP kits, and appreciate their instruction books with all the photos. The main reason I chose this kit over the Sig was the wingspan. I just didn't want to go any bigger than the 76" span. It sounds like the Sig has better true scale potential, if that's what you're into. The functional struts on the Sig sound like lots of work. Either way, I don't think you can go wrong.

SIG CUB better than GP CUB
 
I used to fly a GP60 size cub and I got rid of it because I did not like it. I am presently finishing the sig cub and boy is this one heck of a kit. As far as the GP goes it is very heavy, and does not fly like a cub. Yes the sig cub kit is balsa but I would not go as far as to say that it is not as durable as the GP. Lite ply is used because of the high cost of balsa wood not because of the strengh. No matter what kit you build you still have to be a pilot, I do not build them to crash, I have robart landing gear on mine and boy does it look scale. As far as having to use rudder cordinated with the ailerons that is how a real cub flys. The quality of this kit was out of this world as far as I am concerned. I have built many kits in my life and this is the best I have ever seen.

I do not mean to bud in, but how can the two be about the same with a weight difference of 3.5-5 lb's. The sig only needs a 52 4CYL while the GP from my experience needs a healthy 91 4 cyl. They both have the same approxament wing area. Which one do you think will fly like a real cub.

Flew it (Sig's) today....nice plane to take off and land - very scale-like.

Tried some stalls - WOW! She will spiral down and you must use the full-scale technique to 'save'...opposite ailerons (that did nothing), full down elevator (to get it flying); now start the recovery:) First time I had myself worried :):):)

Dead stick'ed her a couple of time (gotta check the tank out), glides like a glider.

All in all....at 7 lbs. 5 oz. she flew GREAT!!!

Tail skid
Did you try the robart gear on your cub. I just fit it on mine. You said you had to give it down elevater to get it to recover from a spin, do you have the cg correct, that sounds like it maybe tail heavy. What engine and covering did you use. I am powering mine with a os46 fx with pitts and a 12-5 prop. I decided to go away from four cycles for this model. I am covering mine with solartex. The plane is framed up except for the wing panel which I will start this week. I have had many cub kits and this is far the best.

Robart's LG fits nicely - just add some plywood on the fuse floor for the back 4 blind nuts...the front two go through the supplied groved blocks.....

Yeah, I might be a pinch tail heavy - I like'em that way:) I measured it as 1/4" behind the recommended spot.

Engine was OS .52 tilted 20 degrees from inverted - muffler exits out the bottom - relieved the firewall for that!

Covered with Century 21st Cub Yellow Fabric. Came in at 7 lbs, 5 oz. with 7 oz. worth of pilots in her :):):)

Those fuse top stringers will break easily - too easily I think - heck, I KNOW - buddy picked up the model to carry it back after landing and cracked one :( Oh well, such is life.

I have flown just about every cub out there, and the goldberg cub is by far the best flyer on both land and floats. I don't like four strokes, but it flys great with a four stroke 52. Pleanty of power on floats and great take offs and landings at partial or full power on land. We do formation flights all the time with it. The great planes kit is good, but didn't fly as well. The sig and TF kits had major problems, and I couldn't say it was the builder. They were both qualified and build nice planes. Could have been a fluke, but I have never seen a goldberg that didn't fly well. Even flew one that I didn't think would fly that a guy screwed up bad, and it flew well will a little trim. You won't be dissapointed in it.

True, as much as I like GP kits, the goldberg is a tough act to follow in .40 size cubs as far as flying goes.

One thing I would like to mention, whichever kit you get, go with the clipped wing option. Every full size wing cub I've seen can't get out of it's own way in a turn.

What are the problems your refering to?
I assume, by your mention of using a 52 FS, that it is in a 40 size
I was refering to 1/4 scale kits in my posts.

Wrong, the Sig requires .90-1.60 4 stroke.

You are the wrong one here, I am talking about the new 1:5 scale, it has a finished weight of 6-7lb's and is superier to any kit made by GB or GP. By the way any engine you can power a GP60 size cub which is a lead sled will fly a sig 1:4 scale cub even better. The GB and GP cub's don't even look like cubs not to mention fly like them. You are a senior member you should understand wingloadings and how they afect flying habits.

If reading the stats off the side of a kit box were enough information for me to feel like I was making an informed decision to invest a great deal of time and $, I wouldnt bother reading forums.
Sorry to have made you all red.

flap, I wasn't refering to your post at all actually, just stating my opinion. I have only flown one Quarter scale cub, and it was the balsa USA kit on both wheels and floats. It had an OS 120 in it. I liked it so much, I bought one, but mine has a Saito 180. It is a great flying plane, but there are a few slow charecteristics that are not the best. It doesn't detract from anything about the plane, just not as stable as some at speeds right at stall. I like the plane though. Haven't done the large one you are talking about. Will have to watch for one around here.
