SAB 520 Tail Belt Rubbing (Again)
Greetings all,
Last year I got a SAB 520 and had a ton of problems with the tail belt rubbing against the main gear and pulley. SAB was no help at all. I spoke to Amain Hobbies about all this, and they gave me a very good deal on a new 520 kit. I built the new kit without using ANY parts from the original kit. It seemed to go together just fine and the belt looked good, thought I knew it wasn't perfectly riding along the pulley. This was in November of 2025.
Now it's May 2026 and the belt on the new kit is starting to show real wear. These belts should last for YEARS. I am now wondering what I can possibly do to keep this thing from requiring a new tail belt (and possibly more parts) every 6 months.
I could really use some suggestions here.
