e-maxx brushless recommendations

[suvowner]

yea, sorry...........I meant two 2s packs for a total of 4s............its just that looking at maxamps.com he seems to have some nice packs for the e-maxx that fit into the stock battery tray, just a bit taller, so have to get a batterystrap in place of the batery bar, and on 2s 12000 lipo is basically the same weightand size of the 8000 miah 3s packs.........so the idea of being able to drop in a pair of 2s 12000 miah packs for bashing a longertime would be great, then if wanted to race or really show off drop in the 8000 miah 3s pack pair.......just wondering if this kind of flexibility is realistic.......i have plenty of money lol, so from what most are saying here i would be happier with the lehrner motor over the plattenburg..........

yes! i think i recognise you from over at traxxas. there is a guy there that swears by his hv and probably someone that swears by his pletty. the guys here are giving advice from their own experiences. plettys require esc's that can run 4 pole motors, so you are limited there. stick around and more people will give help, i'm not real good with plettys.

If you run a 6s system like a 9 or 10xl. You would get a good run time with the 8000 mah packs. I am not srue how long you want to run.
If you want a lehner the 1950 8t works wonders on 6s lipo. I get pretty good run time on it as well. I have heard good things and bad things on the pletts.
I like the 2 pole motors for have more esc choices and the 2 polers are easier on the esc.
I get close to an hour with 8000 mah pack on 1950 8t motor.

Could he go with a Lehner 1940-6 or 1940-5 non high amp versions and run it in the standard triangle config for the 4s setup and then switch it to the star config for the 6s setup?

With the 1940-6 That should give him around 38,600 motor rpm in the 4s/triangle setup, and 33,800 motor rpm in the 6s/star setup. Or with the 1940-5 it would have around 46,400 motor rpm on 4s/triangle and 41,600 motor rpm on 6s/star setup. None of these are perfectly ideal, but it could allow him to be able to have some flexibility in his setup.

The Lehner non high amp versions of the motors can be set up to run at 2 different kv ratings depending on how they are wired. Could this be setup to be 5.5mm gold plugs that could be switched around to work in the 2 wiring configs?

I dont have a lehner motor (yet:dft012: ) so Im not sure how hard it is to switch from triangle to star config, but theoretically it should be possible to do this right?

to coolhand's point above... Im not sure how long you want to run. I have the quark 125 and a 9xl and 5s 8000mah that I easilty get a good 45min of bashing time out of. I just got a 6s 8000mah setup, but havent been able to run a whole pack yet so Im not sure what the run time is. Should be pretty close to the 5s though, maybe just a touch shorter.

Actually, it should be alonger than the 5S setup.

ok, thanks. I do like the 5s best, now the 9L is rated at 68 amps, and the 4400mah 5s is rated at 60 amp constant, 80 amp burst for 10 secs, so my question now is will this battery get hurt in this setup, or do I really need to spend another 90 bucks to get the 6600mah 5s rated at 90/120 amps? thanks!

I am obviously no expert, but in the long run you are almost always happy to have more miah, unless you are particulary concerned about weight...........

weight is a little issue of course lighter is better, but mostly I want to make sure the battery will live and the money, it's always about the money!

oh yeah, what lipo saver would I use for the 5s? I have not seen one for that many cells yet, not that I know of anyway! I would also like some gearing suggestions--again I'm just bashing, do not know where to race anyway! I would like to go fast and I am planning on keeping the 2 speed tranny to so low speed power and high top speed should be capable in one setup, that's what I'm hoping for anyway--Barndog says he gets 40ish with 16 tooth pinion, is that with the 72 spur?

did I stump everyone, lol...about the amp load and gears?

FYI, edit button! LOL i did the same thing!
