Blinky is the class that roar, efra, ifmar, etc. created for the speed controls that cant keep up in boosted its just the spec class run at many tracks around the world now, very popular, it was created to make racing more competitive, but in my area, it never changed anything except now you need a new motor and battery every month to get fast and have any hope of staying fast.

On topic- I run SpeedZone USA lipo packs, the newest pack is the 6300MaH 65c pack, still waiting on my new one, but so far it has been the best lipo pack i have ever ran, being a team driver has nothing to do with that opinion to be honest. Consider them, you wont regret it. www.speedzoneusa.com
