I forgot to mention that I have been running the cheap turnigy 120 esc's for years. unfortunately they don't make them anymore
hobbyking does have another 120 esc that I think will work fine. you could also check over on OSE to see what they have
I do have a pair of the aquacraft 60 amp esc's with the large capacitor that I am thinking of selling. I bought them years ago, thinking I might go up to sowega to race, but never did, and have never even run them. If you are interested in those let me know
