I have a stock Krytac crb MK2 and it’s just not running how I’d like it. I got the krytac licensed 30k motor instead of the stock 20k motor but it’s still a bit slow. Love the ergonomics and accuracy but even with a 11.1 it’s a bit slower than I’d like. No I’m not trying to hpa it (I might later on) but I just need a quick n easy upgrade of some sort to get this thing running quick and smooth.
