Proper Direction is a small detail.
Here's one for you. I check dirstion of travel every time after taking off once with reversed ailerons, but here's what happened to me last weekend.
I hadn't had my Cu out for about a year and decided last weekend wit was time.
Took it to the field and got it set up; had to reprogram the transmitter for it, and it took a while to ge the flaperons right. Also noticed that the rudder trim was way off. I had a soldered clevis on the control horn end so I just decided to move the arm on the servo over one spline, which got it close. (NOT the way to do it by the way.)
I flew three flights whcih went very well. But when I taxiied out for the fourth I was having trouble steering it on the ground. The initial take off run resulted in the plane pulling to the left, and not being able to straighten it out, so I figured I better bring it back in.
Now I've never seen this happen, but the soldered clevis had slid on the control rod and was loose.
This plane has dozens of flights on it, and I never had a problem with soldered connections before, but....
