Tom:
I have a WH Baby Extra, which is a great aircraft. I just had the occasion to reprogram some servos, and as I was going over linkages, I found the port elevator linkage sloppy. The problem was/is that the hole in the control horn has worn enough that the screw is sloppy in the hole. All the other linkages are tight and slop free. The plane has 59 flights, probably 10-11 hours on it.

It is not a complaint, but a caution for others that the phenolic control horns may need to be viewed as a replacement item.
