yes its a great election! with 40C you will have plenty of toque as well as power for your helicopter. however with 3000mAh you will only be running your heli for about 15-20min max. I recommend you get a 5000mAh!!! it last way longer!
2 thumbs up!
I decided to try one of these smaller packs to see if I could get some weight savings in my HPI Blitz for racing but was concerned with run time. This is a nice pack and although doesn't take as much voltage as some of my other packs, it's lightweight and ran with lots of low end power for 20 minutes plus never seemed to fade. This was running a 13.5 turn Brushless Losi Xcelorin. Unlike some of Turnigy's larger packs , these wires are managable .
