I too was scrounging around for 1/12th built up models, as my club for the last 10 years have raced two pole pylon. Just last year in contact with AirKill, I was able to procure several kits for racing.
Jeff Weiss the owner was very helpful in getting me the right products to me. Right now I have the Rare Bear racer on the building board getting ready for the finals in September. Give him a try.
Below is a link on Airkill.
