I just got mine on Saturday and it's working great. You guys did a great job with the production and programming of this!
I do agree with viper and a few other comments that the throttle is pretty intense. I'm using a Mamba Monster 2 and I feel like this chip/wii-remote has really opened the thing up. I was going to look at making some the adjustments you recommended, do you just recommend an uno/nano and some jumpers to get this connected? I'm not sure which build I have in my possession (says 7/13)
Thanks again.
yeah, the throttle can be very intense if you have a torquey setup. The new code is way better for that. All the production boards have 1.0 on them. With that build + torquey board, I recommend you use C + up/down to manage throttle, then drop C and down for brakes. Practice a few times, different ESCs do different things with braking input. Wiiciever sends exactly the nunchuck value for brakes, no smoothing -- about halfway down on the nunchuck == 45 degrees / 1250ms, which *should* be "half brakes", but your ESC may vary.

I use an Uno for updating, it seems to work very well. I highly recommend. Torqueboards and I played with the new program last night; the throttle works well for his board also, though he did have some gremlins with two units (one brand new and one very old). We're still chasing those, I think it's electrical.
I've got ~30-50 miles on this new code and I've checked it enough that I want more people to try it.
There are 3 different throttle programs in 1.0:
stick only: a rate-limited throttle advance; if you slam the stick forward, the throttle will slowly rise to 100% after about 10s. This is adaptive (technically, a floating ceiling) so if you get the board to 100%, then drop to idle, then slam it again it'll jump back to 100% pretty fast.
C + stick: cruise control. more pressure == faster cruise change. You can more gently increase / decrease your cruise speed. Drop C to coast or use brakes. With no stick input for up to 5s, you can hit C to quickly return to the previous cruise speed.
Z + stick: "raw" throttle. 50% stick == 50% signal to ESC; 100% = 100% instantly. If you're into that sort of thing.
Z+stick or just stick: down stick == brakes, no smoothing. Slam it down, you get 100% brakes.
C+stick down == reduce throttle
make sense? If you just use the stick with 1.0, it's very friendly. Z+stick == aggressive. C+stick = "cruise control", set a speed and hold C to keep that same throttle value.
