Yes that helps. I am scouting other cars now, and one of the things I need to consider is being able to gear for a 270 foot straight. The RS4 3 and MTX2 and even the reflex (I think) are out because of gearing. That leaves the MTX3, LD3?, R12, GT4 and 705. How is the durability of the R12? The one part that concerns me is the lower pivot balls in the arms; and also the composite Axles. Anyone care to admit slamming some boards and breaking some parts?
