Hey everyone out in pattern land, I just got done testing a new power system that may be of interest for people. It's a hacker C50-11XL
spin 99 speed control
8s thunder power 5000mah packs
21x14 falcon carbon prop

with this setup I pulled 80 amps at 2600 watts. I flew this in my spark and provided really good speed and power. The advantage to this setup is it's 8oz less than a 10s setup. I think this power system is great for up to 7:45 flights. I flew for 8 minutes and pulled 3980 out of the pack.
