I just had a situation this last weekend. on the last flight of the day the jet did not seem to have the normal ground tracking. I had a hard time turning to taxi down wind to get to the end of the runway. I just attributed it to the wet grass being slippery and the very large vertical fin area and the wind picking up. I do have the plane set up so that when the gar are up the steering servo is centered and turned off. After landing I was completely unable to turn around to taxi back. The steering servo had failed. That sluggish steering on the taxi out was the plane trying to talk to me, and me not really listening. Fortunately the landing was straight and needed no ground corrections. I did have to walk out and carry the poor thing back to the pits.

Sometimes the plane will talk to you but it may speak very softly, you just have to pay very close attention
