ESC Amperage

[Oblivion]

I'm looking to get an ESC that will work with twin mabuchi 540 motors in parallel. However, i've been told that these will require a lot of current, so if I were to get an an 8-turn ESC that only had a 125 amp continuos rating, would this deplete performance?

It's only that the novak super rooster has a 320 amp rating and 125 does not seem much compared to this.

The SuperRooster can handle 2 15t motors in parallel and one motor with no limit! [xx(][8D] and the Super Rooster is one of the best ESC's you can get [8D]

I also have a Wild Dagger with 2 17t modified motors an a Super Rooster and the SR doesn't get warm after a 3000mah pack. Before the SR I had a carson speed11 with 11t motorlimit and the stock motors and this was a good setup, the esc got a little warm but not hot I let it cool down after 2 packs, and I still use that esc []

So with the stock motors in parallel it will be fine with a 8t motorlimit....

I used my standard rooster(something like15t single motor limit), with two stock silver cans in my clod with no problems. The rule of thumb is that when running two motors in parallel you cut the number of turns in half to get the effective current, so the two 27t motors in parallel is about the same as a 14-15trn motor, so choose an esc accordingly, of course if you plan on upgrading motors at all, you'd be best off getting the super rooster now.

With twin mabushi 540 anything will do. Do not forget that the stock mabushi consumes 5,9A at best efficiency... I presume you could even use 2 * 27 turn motors with no problem. Just have a look at the max current drain, and multiply it by 2, plus a 20 % margin.

On my clod I am using a vintage transistorized boat speedo (not even FET !!!) capable of handling 50 amps max and everything is Ok (does not even get warm).

That's not taking into account stall current load, but. [8)]

Generally speaking, most ESC manufacturers say that 2x 27 turn motor limit is about the same "half" that, ie a 13.5 turn motor. []

So some ESC rated at 13 or lower should be safe.

Well I'm interested in the LRP F1 Pro Reverse Digital speedo. It has no motor limit and has a peak rating of 270 amps and a continuous of 55 amps. Would this be powerful enough?

Yup, that should work fine.

Have heard recommendations that you shouldn't use the

reverse for extended lengths of time (the current capacity

of the reverse FETs are usually lower than the main drive FETs)

otherwise the overheat protection might kick in.

Novak Super Rooster is also a great choice too.

The case on the LRPs feel a little flimsy (like lexan)

but that's just a personal thing.

OK, thanks. By the way, I'm getting my accounts mixed up. My username is Oblvion, not Dagger Thrasher. Sorry!
