6xl with 8 cell lipo

just wondering if u guys think the 6xl motor can handle 8 cell lipos. im not going to be running for a long period of time. just for like a little big. im building full on drag truck.

thanks!

oh and if u need to know the esc i well be using is a castle creations phoenix hv-110 esc.

I don't think it will do too well. It could get up to around 80k rpm, which I would say is too much for a feigao xl, even for a short time. But I could be wrong if it's only for drag racing, since there's some drag racing setups out there that don't sound like they should be able to work, but still do.

yah i know one guy has 2 7xl motors with 2 5 cell lipos on it.

If you mean JOHNNYMAXXIMA his 7xl's only see 5s each (he uses 2 5s packs, but they're not in series), so max rpm of around 44k.

oh ok.

i guess i could just do dual 6xl motors and dual 4 cell lipos.

What car will this be going in. You have got to post some pictures and video. That will be an insane set up.

its going into a emaxx

If I'm not mistaken when the feiago's go over 40k rpm their rotors could self destruct. Some my be able to go a little higher but they are really not built for that kind of speed. The bearings are not built for that either.

I wouldnt spin a feiago over 60k rpm or you will probably rip the magnet right off the rotor, but... I guess you just dont know until you try it. It should be pretty insane anyway.

With that kind of power you are gonna either flip the truck instantly or the wheels are just gonna spin like crazy depending on traction.

well if i do the 2 6xl motors and 2 4cell lipos it well only spin about 44k rpms each. so they should be fine.

and is there any way to change the bearings in them to be able to handle more rpms or just make it spin better?

Upgraded brgs rated for 70k rpm. They are a pia to change however due to the rotor magnet. It can be done.

I have run a 7XL on 6s (over 50,000rpm) quite a bit, no problems so far (knocks on wood).

Where can u buy the 6XL motors ?

bdebde, what ESC are you running with the 7XL on 6s ?

you can buy 6xl motors at impaktrc.com they are about 70$

i know on my 6xls im going to be running the mamba max esc.
