I just replaced the flippers in my Pinbot. The one seems just fine. The other is fine for a while, then stops working. If I leave it alone for about 10 minutes it will start working again. I'm thinking this is a heat issue. I had to replace some of the wires because the existing ones were too short after removing them from the old flipper assembly. I'm wondering if the wire I used can't handle the heat. Any thoughts?
