Hi Jerry. The R/C airplane Im holding is my Original Designed Dart 1. I made a series of Darts and had Dart 3 published in the now defunct RCM (Picture of front pages of RCM). Can you email me a copy of your "Two Cycle Glow Engines". I would like to make copies to pass out to my students and club members. Talking about FUEL, I have traveled around the world and flown model airplanes at every base I was stationed and many times I had to SCROUNGE alcohol and Castor oil to make fuel so I could fly. I have been mixing fuel for over 50 years and there are NO SECRETS. I have transported R/C models strapped to Missiles in my fighters missile bay. In the late 1940s when racing control line speed I would go to down town NY City to a Chemical House (Store) and buy chemicals in glass 1 LB. bottles. Alcohol, Nitro Methane, Castor Oil, Oil of Merbane (Not sure of spelling)(Has another chemical name) smells like shoe polish. We would mix the fuel at the racing site so it would fresh. We never used more than 40% nitro and eventually accomplished the World Control line Speed record with our Hellrazor on 2-.016 wires. Enough RAMBLING ... Col. Chuck Winter
