Well since we are having a brushless controller comparison I am going to throw out my little opinion. I ran and still do LRP Spheres, and yes I am very tired of running back and forth from the post office getting them replaced. So during a race weekend I was out 2 spheres in my off road 4wd buggy and the shop only had the Castle Creations product. All I can say is I have had great success with that ESC. It never thermals, the choices of motors is always expanding because they can run the new Orion/Peak motors, and I can really dial in a personal feel with the usb port and Castle Link software. I can spend a very limited amount of time dialing in the throttle and brake curve with my laptop and poof test it on the track 1 min. later. How does everyone else feel about Castle's product? Since it isn't raced by the pro's it seems to not get the headlines but I feel for what is currently available it performs well, has a manageable case size, and is most importantly reliable. I have not used Novak's esc because it plain doesn't fit in my buggy with the fan but I can get the Mamba to feel every bit as good as my LRP esc's.
