The Castle Link is great

Got the Castle link today and it is awesome. I was kind of worried with the hydra since I could only set the cutoff at 12 V but with the link I can choose any setting. The ability to control the throttle curve is very nice to.

I love the link. I change my throttle curve to max out about 90% of the pulled trigger
