#0 sourceAnother thread got a couple of stories of first flights, so I thought I'd open a thread devoted to the topic.
I had a number of aborted attempts when I was in grade school in Wyoming with the usual suspect Cox PT-19. Mostly I remember nitro from the fuel stinging cold cut fingers and a lot of time spent trying to start the engine.
Later when I had moved to Arizona I decided to start seriously to learn to fly control line. I determined that light full airfoil stick and tissue Guillows models with an .049 would be a better bet then the heavy plastic ones. So I started building with nothing more than my determination, imagination and the Guillows instruction sheet as a foundation.
I was certain I wanted to be able to control the airplane. Knowing nothing about control pressures or elevator effectiveness or--for that matter control sensitivity due to CG--I build a series of the big WWII fighter line, a Mustang, ME-109 and eventually a Spitfire. In each case, I built a solid elevator for control (shifting the CG aft) and geared up the controls so that a small amount of control handle input gave full up or down.
I literally had no idea what I was actually doing setting up the planes to be so sensitive.
Each airframe, lovingly build and finished with considerable detail, lasted roughly a half a lap of increasingly divergent oscillation from level flight before impacting on the local school yard grass and shattering into a silkspan bag full of balsa shards.
All I knew was that the flying business was demanding and difficult and that perserverance was supposed to be the key to success. So I would salvage what I could, deposit the debris in the trashcan and go buy another Guillows fighter kit.
The famous first flight that I remember most from my youth took place on a sunny Saturday afternoon at the local school yard where I had set up my most recent accomplishment--a Spitfire all dressed up for the Battle of Britain and sporting a three blade prop.
I fired up the venerable Baby Bee, walked the lines out to the handle, lined everything up, made sure I had full up to keep from nosing over (Full up being 70 degrees of elevator deflection) and waved for release.
After a short ground run, the Spit pryed itself off the grass and commenced the entry to a loop from ground level at slow airspeed. As the nose pitched passed 45 degrees I slammed in full down elevator in an attempt to staunch the staggering climb. So the Spit commenced entry into an outside loop from 10 feet or so. And we were off to the usual races, the airplane wildly out of control, pitching up and down radically as I alternated between full up and full down in an attempt to stave off one form of recurring disaster or another.
At one point, the Spit was headed down hill and not responding as I thought it should, so I instinctively jerked back on the strings while pulling up to avoid the ground.
What happened next amazed me.
Somehow the airplane did a snap-yaw pitch turn and ended up pointed more or less right at me and at about 8 feet or so of altitude, wings level. Clearly the airplane was now doomed, since I could not possibly exert any control whatsoever.
Or so I thought.
The lovely little Spitfire settled into a stable level cruise and flew directly across the circle, over my head, dragging the useless control lines behind it with all of the calm assurance a free flight design can display. I watched in awstruck confusion as the airplane demonstrated an obvious and profound talent to fly much better without any help from me at all than any of the prior flight attempts had produced with my fervent but inexperienced hands on the highly strung controls.
It hit me like a rock.
The airplane was better at flying than I was and my obsession with making sure my control input would be responded to was totally counterproductive.
It was a lovely sight, that little Spitfire, gracefully cruising away from me.
Until the lines finally tightend up and the airplane jerked around on the leash. I only managed to curtail my control inputs slightly as the racuous roller coaster ride resumed and the airframe was destroyed on impact a quarter of a circle later.
The next one I build had far less control imput available and the CG was studiously set per the plans.
And then I began to learn to fly.
Any one else have a memorable first flight experience?
Cy.
