is this a good race revo setup? - Page 2 - RC-Monster Forums

Tower now carries FlightPower/TrakPowers.

I'd personally get a 1950. It can be used with a wider variety of ESC's, though I have been waiting nearly 6 months for mine (and still am). The Neu's are great, don't get me wrong, but I'd personally get the LMT.

so there nice motors but hard to get? dotn wanna wait 6 months for a motor..

1515 2.5 is now back in stock and I ordered one a few hours ago.

oo.. well i meant the uhh 1950 or w/e those are lehner right?

jollyjumper · 05.01.2007, 10:00 AM

1950 is lehner.
bk doesnt distribute lehner anymore and thats were mike got them from i think.

he is now probly trying to get them direct from lehner.

so if you want a motor now you gotta get a neu.

Has anyone tried charging regular lipos to something like 4.1v/cell CC/CV threshold? It's not much, but would lower overall voltage by 0.6v for a 6s pack.

jhautz · 05.01.2007, 02:41 PM

I havent charged them to the lower level specifically, but as soon as they get down to a static voltage of around 20-20.5v the Quark runs 6s lipo just fine. I did it using a watts-up meter in line with the packs just to see what the voltage was when it stopped cogging at start up. It doesnt take much of a voltage drop to make a pretty big difference.

BrianG · 05.01.2007, 02:48 PM

Wow, that's a little over 3.4v/cell. Hmmm, sounds like the 125B is a SOLID 5s ESC, and marginally acceptable at 6s.

Serum · 05.01.2007, 02:58 PM

With the right cells (flightpower/enerland) 5000 it takes 120A to get them on 3.5V per cell. (not kidding) at 120A they still do a 21V.. not considered a 6S ready setup that way IMO..

Thanks for sharing Jhautz!

t-maxxracer32 · 05.03.2007, 12:42 PM

wow tha made no sense to me ^^^

i think i might get the quark and then just get an 8xl motor and if i want more then upgrade at that time.

BrianG · 05.03.2007, 12:52 PM

Jhautz pointed out that the ESC likes voltage only as high as ~20.5v, but at 6s, that's only 3.4v/cell. Serum is saying is that some cells hold their voltage better than others, so you shouldn't count on a certain level of voltage drop from the better cells. In short, don't do 6s on the Quark.
