SIG RC Kits 41-60 - SIG's Model Aircraft Kit and ARF History

SIG Radio Control Kits

(Kits 41-60)

Active kits shown in BLACK

Discontinued kits shown in RED

NOTE: Clicking on most pics will bring them up, much enlarged, in another window.

It seems that I must put this statement on each page of the website.

I have NO affiliation

with

SIG Manufacturing Co.

I do not have magical access to kits. I do not have a store that sells kits.

I do not have access to, or sell kit parts. I do not create kits.

I do have a website that shows every kit SIG has ever put out.

You are seeing it now.
