TOPIC:

I have these two marine esc the marine 15 is new and the marine 25 is almost new only used once then removed from the boat any ideas if i could run these in a tamiya car? is the spec ok?

Sure you can run them.... but... you'll have no brakes, and they may get a bit hot. I wouldn't run them on any 540 sized motors. maybe a 380 sized motor or smaller. I KNOW! use em to upgrade that nikko, or new bright that might be hiding amongst your real rc's.

I don't see why not, be it that the Marine 15 is a little light (15A).
Should be alright with a silvercan though.
Thought I read they had programmable break btw.

Cool... I didn't figure that a boat esc would have programmable brakes. Silver can.... maybe... but i would invest in a temp gun and watch the temps.

Why only a 380? the boat it came out of had a 600 motor fitted?

I think he's just recommending on the safe side.
Ya basic 600 boat motor seems to be a bit heavier even (about 12A max) than a silvercan...
But maybe a car's more volatile current demand puts more strain on the ESC?
