I have a 2.5 year old 80lb Ultrex Link. Have had no problems. In a tournament on Saturday, the foot pedal gets incredibly stiff and then just locks up. I know about the frozen foot pedal issue so I grabbed my remote and was able to steer through the remote. I check the pedal several times and it is very, very stiff if not frozen (I can turn it about 15 degrees by really pushing hard). About an hour after it all started, I instinctively tried to turn the pedal with my foot and everything was back to normal. Worked the rest of the day without issue.
Any advice?
