Well, I just got round to trying out this update in Cold Fusion (brushless Dagger), and it's a huge improvment IMO! I'm only using the standard 5700 motors, but the entire throttle range is much smoother now, as well as startup of course. Braking is also much smoother, and now seems to allow you to just hold light brake for as long as it takes for the vehicle to stop. I don't remember being able to do that with the old software. The whole drive is just seems more relaxed and sedate (almost brushed in feel)...until you open the taps.
I know I'm just telling you lot what you already know, but just thought I'd spout my opinion. Good job Castle!
