I am having problems with my latest 5925MG servo. I just finished my latest touring car and was trying it out on our local carpet track lastnight. I kept having problems with the car not keeping the same center, had to keep adj the steering trim. I pulled the car and checked the steering for binding and loose parts and found the servo horn mounting screw had loosened up. I thought I had found the problem but when I tried it again the problem kept getting worse untill the wheels kept steering to the left even if I turned them right. I pulled my old car out and used it to race for the night (won the A main but I have never had a problem with a hitec digital servo before. Any ideas?
