I know there are a lot of hardcore STS fans around, and 46U aren't your sponsored by them?? But no offense, with the number of people(many of whom are competent too...) having trouble with them, I wouldn't go near an STS... There are some pretty persuasive videos out there, and I know they CAN haul, but I just don't want the risk of a PIA engine - OR having to replace O-rings and carbs or whatever... STS has really screwed themselves recently IMO - too many engines blowing up, proving untuneable(except by pro engine-modders, etc...), etc etc...

No offense, but I'll take an easy-to-live-with Axial any day, regardless of how much more powerful a well-modded-and/or-tuned STS is...
