Game Changer RC brings you just what most of you been asking for. You get the Ultimate Transforming experience with the ability to change power supplies in your RC at anytime from 3s, 4s and 6s with our new Futaba into Balance lead plugs or the original Balance lead to balance lead plugs. If you don't have the new plug system on your fans you can just request to have 3s, 4s or 6s balance leads instead of the Futaba plugs. This is the new way with GCRC but we will still supply the original balance lead plug n play system as well. As always we appreciate all of you that supports our mission which is to keep bringing new and innovative ideas to the RC community. Thank you and remember #Letschangethegametogether  

GCRC fans with the Futaba plugs cannot plug into the receiver or ESC they require 11.1 or 12volts for full power experience. We do have a low profile fan available that can be plugged into the receiver or ESC just inquire for more details
