So yes....it should take 5s and has more FETs than most other controllers (aside from MGM), so it has excellent power handling abilities. The boards have a lot of copper in them as well, and a little air over the motor/battery wire standoffs will act as a heatsink. The small footprint makes it quite easy to install as well(though a heatsink case and switching BEC will make the 1/8 controller larger). The R1Pro is gonna live in my 1/8 buggy and the truggy will be the test dummy for the 1/8 controller when it is ready. :)
I suspect the R1 and R1Pro should be on the shelves any day now, actually. Tekin is trying to keep their mouth shut until they can deliver the product at this poinit. It is pretty tough to nail down a release date....especially round the holidays. :)
