I finally got started on the upgrades for my BR. For those interested, look for my 'build up' thread in the RCC forum. For the rest of you, today's upgrades involved the front upper & lower A-arms, rear trailing arms, servo, and receiver (this last one because I plan to use my 7PX, as I do with all my other vehicles, plus I'm using the SR-Mode of the Rx). There are several other upgrades coming, leading to 3S running ability, but they'll all be covered in the aforementioned RCC thread.
