I bought a cheap ESC today and decided to try it out. I bought a Dynamite Tazer 15 turn ESC and decided to run it in my Rusty. Well, I know that the limit for this ESC is a 15 turn, but I am running my 12x3 D4 on it and it seems to run great. It can handle up to 7 cells I believe but it could be 6 for all I know, I haven't read the spec sheet yet. Anyway, I ran it for a good IB3600 pack full with the D4 motor geared at 18/84 and it seems to be a pretty decent cheap pickup. For $30, I couldn't beat it. I ran my Rusty with my nitro's wheels and tires on it and it's really not too bad as far as performance. The only thing I don't like about it is that the switch is so small. If anyone else has tried this ESC, let me know what you think about it. If not, let me know what ESC you're running.
