Great motor on 2S

Got the 12L version of this motor for my 2meter poly pulsar,, was a little concerned about having enough power on 2S,,, but,,,, NO worries!!! Has PLENTY of power on 2S., pulls my 19.5 oz pulsar up to 200 meters in 15-17 secs
With static amp draw at 25amps with aeronaught 12x8 prop. Nice being able to use the both cheaper and lighter 2S batteries.
