We took 4 13 pros up last weekend 3 stock and one turbo and didnt have a single issue talked to three dealerships here in wyoming and no one has had one come back broke yet.... Where are most of thease guys from with the broke drive shafts back east riding their 155s and 163s up and down the ditches I see all the posts about the broken shafts but have yet to see one come back broke sounds like a huge problem to me !
