I am converting to a 6S or 8S battery system because of new motors. So...that means that I have a complete set of electronics available. I even have a spare Power distribution board. I need to have someone take these off my hands so please let me know if you are interested at all. One PDB has been completely rebuilt by Mikrokopter through QC and all have have been functioning perfectly. Unfortunately the 4S limitation doesn't serve me any longer. I have pics and all information if you need it. Great deal for anyone!
