I need help in deciding what my next kit should be to build. Here are the ones I am thinking about or recommend something that is fun to build.

GP Super Sportster
Sig 4 Star 120
Sig Astro Hog
Sig LT 40


Kits that I have built:

4 Star 40 and 60
Something Extra
Hog BIpe

You can't miss with a 4 Star.......

I've built 3 greatplanes kits in the past year, I've been very disappointed in the quality of the wood, especially the ply that is included in the kits.... I'd say stick with the sig kits out of your 4 choices....

The Sig Astro Hog is a classic and an excellent flyer. I have built and flown three (tail dragger versions) over the years.

Aloha,
Balsa USA has some nice kits and their wood is very good. AMR also has excellent kits in the larger gas powered models-all computer cut, with excellent wood, quality hardware and parts fit. I like Jack Stanford's kits too, some of Joe Birdi's kits and I loved L. Andrews kits. Midwest, Airtronics, and a host of others put out good kits in their day, and some are still available.

My next kit will be a 30 year old Robin Hood 80, and currently building an AMR kit.

Soft Landings Always,
Bobby of Maui

Out of your list I would do the astro hog
If you have already done a 4* 40 and 60 a 120 will be pretty boring
LT 40 even more boring
I'm not familiar with gp kits.

BUSA rocks big time. there are many great kits in their collection, great plans and wood, heaps of help if you need it.
They have 1/6 1/4 1/3 WW1, and a few others inc Cub and Mustang. Worth looking into http://www.balsausa.com/

I suggest that you've built enough Sig kits, and it's time to experience something different.

Sig does have a Craftsman Series that may spur your interest. They will certainly be more of a challenge than what you've been doing.

The GP Sportster may be a good choice. I prefer their flying characteristics over the other models on your list. Building the nose of the fuselage may be a bit of a challenge, but the excellent Great Planes instructions will get you through it. Unlike mattnew, I haven't had issues with GP ply, but I haven't built a Great Planes kit in awhile.

The main thing is that you want to build, which is comparatively rare these days. Everything on your list will yield a nice looking, and great flying, model.

The suggestions of AMR, BUSA and Stafford, aren't bad, either. All will be different than you are familiar with. I consider that to be a good thing.

Please let us know what you choose.

I have a astro hog kit on the shelf, I like the look of it myself,so if you like that build it, it's a bit bigger than what you have done.
If you want a bit more of a challenge, a WW1 BUSA bipe like the 1/6 sopwith pup will test you a little more, but certainly not hard to build.
I have the 1/4 and I think they build pretty much the same, you will find 1/4 will be more stable in the air though.

The Astro hog is probably the most complicated kit to build on your list. After that, try on a Sig Liberty sport kit, if they are still around.

The Hogs are on backorder right now anyway. I just ordered one the other day. So if you're looking to get started, you might want to choose something else.
