This thread is started as a place to post links to kit manufacturers, kit suppliers, kit cutters, and plans suppliers.
Posting links to aftermarket accessories and parts suppliers will be great too.
It is preferred that links be to the home page instead of to particular kit page, but all links to help the people searching for kits and accessories are welcomed.
I am not sure what to suggest in the case of a particularly bad business that should be avoided. There have been a few of them documented in other threads. Use your best judgement when posting about that issue.
If the thread can be kept on topic it will make it a better resource for those looking for kits and accessories.

A few to get started.

Hi,

ptmac3 posted these links in a recent thread I started about high quality kits. It includes kit manufacturers and kit cutters. There is some fantastic stuff here.

As you find the rest of them post em back here for the rest of us.

This one looks interesting, particularly if you're a bit of a dreamer (like me):

http://www.ne-aero.com/

They do some kits but the thing that caught my eye was their page explaining the custom kit manufacturing service they offer. Ever wanted to market one of your own designs? Have a look for yourself at:

I haven't seen http://www.ak-models.com mentioned here yet.

AK Models does custom laser cutting and markets their own kits as well as reselling CMPro, Nitro Models, and Rich Models ARFs. They're located in Iowa City, IA and they have a very good reputation for customer service.

I purchased this Togo kit from Doug Lee (the plan is well laid out and includes building pictures and construction notes). Outstanding flyer if you are into Sport flying. He also has many scale plans, short kits, and full kits/arfs on his site.

FunFlyer,

Thanks for the link! I've been looking for a Tiger Moth kit in that size. It looks like a nice choice. Thanks again.
