Well after hearing about how awesome this adapter is from Castle Creations on a bunch of different forums, I was determined to get one after trying to program the ESC via the transmitter *it sucks*. Luckily for me, I met a person in another forum who had a spare one lying around who just happen to live in my state and he gave it to me free of charge, he even paid shipping! Just got it today and I rushed upstairs to give it a try. Wow, no wonder alot of people rant about this thing! You can adjust throttle/brake curves, Lipo cutoff voltages, timing, TX delay, view graphs of throttle punch, change reminder beeps and everything else you could think of!

Now I can really tweak and play with my Flux so its just right. Its just so amazingly cool that I can plug in a modern R/C car now via my computer and program it! Amazing how things have changed since I had my first R/C Nikko Chipmunk car back in 1987 and my first real rc car, a Team Losi XXT 2WD Stadium truck back in 1995. The computer nerd in me love this and I'm very glad I got a Flux over a Baja 5T. Once I got over the initial "scared" stage of LiPo's, I could never even think about using NiMH now! Long live the new era of brushless LiPo programmable powa!!!

EDIT: So far, using the most current firmware and software versions, I have not run into any issues using it with my Vista 64 bit OS
