RE: pylon racer plans
Hi WC....I don't have any drawings, but you could go to Toads RC site for some information. The pylon forum might have some help. The NMPRA might also have some links. I fly GLHs in a restricted class of .061 racers, they were kitted by ACE RC long ago. There might be 1/2A racer plans available at the RCM plans catalog. The Taperwing is a good design.
Don't look at the AMA competition guidelines for help or you will end up building something that looks like Noahs Ark.
