My son wants to start training. So I get my old trainer out (soloed with it in 2000) and get it ready to fly. Add an engine, receiver and a couple of new servos. Get it set up on my computer radio and get the throws set up. I get the engine running and tuned. Great, off to the field to test fly it.
At the field. Fuel it, check the cg, check the batteries, range test it and then start it. Everything looks ok. Put it down and flex the controls. Run it out on the runway. Start the takeoff run, it pops up off the runway and off we go. Looks good. Crosswind is pushing it left, which is the way I want to turn. So I start to fed in some right aileron to slow the turn down. It keep turning left, but even harder, So I give it more right. Now it is heading straight down. So I cut the power, let go of the ailerons and pull back on the stick hoping I have enough altitude. The plane lands across the runway with no room to spare. I even clipped the high grass on the other side of the runway.
What happened?
Three of us walk out and take a look.
Some how after setting up the plane I reversed the ailerons.
I was lucky to get it down in one piece.

So, pilots, don't forget to check everything before you fly.
I got complacent and almost lost this plane.
