RE: High thrust 70mm EDF HELP !
Could never understand why everyone goes for CC speedies when there are other products out there as good if not better, with less failure reports to boot. The HW Platinum PRO 100A 2-6sESC is one of the best on the market, compact, super tough, has a voltage adjustable switchmode BEC built in, huge array of programming features, and a better reliability rep than CC does, plus its generally cheaper to buy too. I run it over 100A constant in a 90mm 6 cell jet, running ARC3665-1 which pulls 100-110A on 6 cells, the speedie heatsink is in my intake duct and barely gets warm.
You may have trouble finding 2858 motors right now, I have4-6 left in stock from memory, most dealers have been out for months.
