No I have not posted anything on Caswell... I was not aware they had an rc forum but I'll go try there! I don't know very much about speed controllers, but I think it may be overheating in the cramped space. I hate to spend money if I'm unsure of the outcome, but if no one can help me I may buy another esc and try mounting it outside of the wtc where it'll be cooled by water. Do you have suggestions for other speed controllers or should I stick with mtroniks?
