chapter 4: at the field!
when i started building models, the only way was free flight. but i just built them. i could not make them fly. tried winding the rubber band and launching, but the plane went bazuk. nothing worth watching.
so for several years i just kept building and improving my skills, until 1 day i met a guy that flew models and he told me that the local air force allowed modelers to fly at the local airfield. i started going there and began to learn what it takes to make a free flight model fly. took me a long time-so much to learn-but was a most rewarding experience. there were the youngsters like me, who flew rubber powered planes, and were scattered all around, and the men, who flew engine powered planes, at the center of the field. those guys arrived early and set camp with ropes and a tent, chairs and table, and dressed as explorers, including a safari hat, and were full of themselves. didn't let us to enter into their camp, so we just watched in awe from the outside those wondrous, humongous planes covered with silk and powered with super cyclone and anderson spitfire engines. and then i watched some getting into thermals. they used dethermalizers, some with a parachute that was kept in a box in the fuselage and when released by a timer, trailed into the wind and dragged the plane down. others used spoilers on top of the wing. then Carl Goldberg invented the tilt/up stab that became the standard since. l learned things like to use long rubber motors and to lubricate and wind them with a hand drill and stretch them; to make a free-wheeling prop, to use shims to change incidence, down and side thrust, to slide the wing back and forth to change the cg; to warp the wing and tail; to turn on glide only tilting the stab; so many things. then folding props. the works!

wonderful times when we discovered flight, and it was the most amazing experience (and still is).
by the way, folks, if anyone has pics that want to share, bring them here. you are welcome.
