RE: EFlight Extra 260 Help
I have the same Park 480 with a 3S 2100 in a GP Extra
I am getting a good 10 minutes with 50 % to wide open throttle with my 3S 2100 pack with an 11X7 Apc prop.
It weighs 27 oz. and flys very nice.
Weight make a difference . With a 3000 you will gain flight time but loose noticable performance.
