These are the "V1" speedfreak fans. They are meant for speed runs where you need maximum cooling. If you are bashing we recommend the V2 basher fans since they draw less amps.
You will receive one fan with a grille in the color of your choice. These have a JST plug which can plug directly into a receiver or you can run an adaptor to a 4s battery.
