The Rspro really does work fine as long as you have the right cap and a seperate BEC unit. It is actually rated to higher current than the Rx8 on paper due to the 48 fets on 2 circuit boards, but the Rx8 handles more constant current due to teh very effective heatsink and fan. The Rx8 also does not need a large external cap or the seperate BEC unit.
Secure it well including the large cap and make sure all the solder joints are nice and clean. Not a lot of flopping wire and not to tight either. Good installs make for better race days
