Not that it's a huge difference in price, but both Tower Hobbies and Horizon Hobby have the pieces listed at lower prices than FMA Direct. It's still a hefty price, but if you are just getting ready to go lipo it's a great place to start, at least on paper.
I expect to have my scorpion setup in just about a month. I'll report back once I have some information. The write-up in RCDriver is very favorable.
