Oh my yes, there is always that one special that imprints on us and becomes a favorite and it may not even be the best or the worst.

Now with 2.4 its wonderfull that some of these old favorites can actually fly agine, heck even if they are crude by comparison to the stuff we have now.

I be looking forward to hearing of your special projects HP[8D]

First things first. I'm building 3 Quickies over the next 18 days.

- - - - By the second glitch, suddenly he shoved the transmitter into my hands. My problem was now it's glitches and the fact that every time I attempted to pull up, I throttled down. Adding power made it dive. Thinking about it too long would just freeze me on the controls. - - - -
I suppose this would be similar to the time I made a flight on a 120 Super Sportster. My Radio was fairly new, and when I landed I went into the programming to adjust the throttle idle speed. Of course having just flown I didn't go through the preflight check of all my controls before the next flight. When I took off I very soon realized My ailerons were reversed. I managed to get it turned back downwind, but whenever it needed slight changes I could not make my mind move my thumb in reverse even though I recognized what was going on instinct took over and made me turn the wrong way. Instead of continuing and trying to land I weighed the risks and throttled back making a rough but safe landing in the weeds. It was after bringing it back to the pit that I realized I had reversed the ailerons while trying to find the place to adjust the throttle.

Naturally after I landed and explained the situation to the guys someone said, "Why didn't you just turn with your rudder?" Well DUH me. BECAUSE I DIDN'T THINK OF IT IN TIME. It's what is called tunnel vision.

Might be easier if you just forget the surface the stick operates, but lets call it 'direction' and 'speed' and 'height'. That way whatever surface controls the direction of the thing gets hooked to the stick that operates that channel, 'Speed' is then hooked into whatever stick controls the elevator, and if you are using an engine, then 'height' just gets plugged into whatever stick operates the throttle or speed control.
So, if my plane is flying straight and level at half throttle and Ipush the "height" stick forward is it going to climb? The answer is maybe a small amount, but it's largely dependent on the type of plane, wing airfoil, etc. The most noticable change is that it's going to go faster. Similarly, if Imove the "speed" stick, the most noticable change will not be speed, it will be altitude.

I had reversed the ailerons....
A flying buddy replaced the aileron servo on a plane, and changing brands of servo. What he didn't realize was that they turned the opposite direction. He didn't even past the end of the runway before rolling upside down and splattering it right on the centerline.

It's not really a question of what the sticks do, it's a matter of how you think about it. To make an airplane climb, you'll ordinarily add throttle and give some up elevator. To descend, you reduce throttle and use some down elevator. I was taught (when learning to fly full-scale) to think of these processes as using the throttle to change altitude and the stick to control speed, and that's what I teach beginning students. It's useful because it discourages the all-too-common impulse to push the stick forward when you see that you are too high to make a good landing. Nothing good will come of doing that. But you're really using both throttle and elevator when you climb or descend, most of the time. Some full-scale pilots fly ILS approaches by using elevator to stay on the glide slope and throttle to control speed, mostly because staying on the glideslope is more important than being at a particular airspeed, and planes react faster to elevator changes than to throttle changes.

We do seem to be wandering pretty far from beginner stuff here.
