The cost is totally prohibitive, even for the early adopter market. Boosted - I was working on this problem (far less successfully than you - hat tip) and came to the conclusion that you have to give people a low starting cost and the ability to upgrade over time. Give me brushed motors, NiMH batteries and cheap trucks to start with for closer to $600USD. Once you've hooked me on the product (and I'm confident you will) offer me upgrades to LiFEPO4 batteries, better bearings, brushless motors, RadiKS wheels, etc. Up-front pricing will not win this market!
