RE: Difference between CT4-S and CT-5?
very limited as i understand, the ct5 has a better belt tensioning system to stop throwing the drive belts. the ct4s needed the tensionors added or modified. there are a few other small changes. imo, the ct5 is worth the few extra pennies. imo, also get a GOOD radio system in it. i was/am not a fan of the SKION personally.
