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?

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.

I don't see a problem with using 6s A123 on the Quark. It would actually be perfect for the Quark. Quark only has problems with 6s lipo at full peak charge. Once the voltage drops a little from peak, it works great. The A123 6s pack will peak at a lower voltage than the 6s lipo so it should work perfectly.

I do agree that 6s A123 will be too much for the MM.

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.

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

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!

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.

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.
