Spedix IS35 35A 4in1 5S ESC 20x20

The Spedix IS35 is a solution to an affordable 5S-rated ESC for your micro drones. This ESC has a burst current rating of 45A which makes it one of the best ESC for your 4 inch even 5 inch FPV racing drones. The small 20x20 footprint lets it fit easily even in a 2 inch frame. Pair it with 20x20 flight controller like the BrainFPV Radix Li or Heli Nation Talon F7 FC to make a solid 20x20 stack. 

The IS35 is a new 35A 20x20 4in1 running BLHeli_S and current monitoring.  It comes with cables to enable direct connection to flight controllers.
