RE: History of Senior Telemaster
Was the purpose of the lifting stab to allow for a wider CG range for payloads, or to minimize trim changes with airspeed variations, or both?
-A bit of trivia, I noticed my early '90s Sr Tele kit says ''Another Great Planes Kit''. Did Great Planes make Sr Telemaster kits back then?
Quite a lot of the old free flight designs had lifting tailplanes. I believe Denzin was just following a practice which had been successful with his earlier designs.
I don't know whether Great Planes ever made the Telemaster but Precedent made them under licence in the UK. Have you ever compared the T240's flying surfaces to those of the Senior Telemaster? Aerotech also sold Telemasters in the UK back in the 1990s but I don't know whether they cut the kits themselves or imported them from America.
