can I achieve this simply through swapping for a lower turn count motor? at sacrifice of torque I suppose?

currently running a 55t integy lathe.

what would the internet suggest?

yes you can do that and sacrifice some tourqe, but i suggest you get a lower turn motor (like a 35t or 45t) then volt up (bigger battery, and gear it down a little, and then youd gain your tourqe back

I have an r2d tranny T-rex 60 axles
and an 8t and 11t pinion at my disposal.

if i volt up to an 11.1 will i have to get a bec as well?

i havent put the 11t in yet, i could try that I suppose. or will it be too big of a jump?

im guessing if you switched to a 35t motor and 3s battery that would be a big jump in speed and torque. i switched from a 55t to a 35t and it has loads more speed and just a tad less torque but i use it as a trail rig so i dont notice too much of a diff

You could try the 11 tooth pinion, see how it climbs and how hot the motor gets. Gearing up loads the motor which also produces heat (not a good thing if it gets too hot.
Motor may be warm after a hard run, but you should still be able to put your fingers on it without burning them.

You havent given the specs on your ESC yet, but more than likely, you will need an external BEC at that voltage.

novak wooster. sorry bout that.

entropy · 01-31-2011, 11:26 PM

A good 45t might be the ticket

Ahh....ok. Well, nevermind the folks saying to bump up to 3S, that ESC wont handle that voltage.

im running a rooster crawler esc on 3s, no problems so far, but need to use an external cut off as the rooster is only for 2s.

search for rooster and you get a few answers. seems fine to me judging by what i've read. i use a 1300Mah and get about an hour runtime

Yeah, I've heard of a few folks running them with success....I was just going by what Novak recommends.

I use an external bec anyway even tho the novak puts out 6v. it seems to put out a touch more power anyway. I would definitely use a lipo cut off as well.
