How about this bl setup?
 

wanderer 9xl
BK Electronics 12020 Warrior Controller
using 16 cells GP 3300

I would like to hit 50mph or high 40's and still have arm pulling off torque.

only 16 cells? i'd go with 18 or 20.

I would say 18 is the limit with a 9XL. Coolhand_country has tried20 cells and said it would heat up to above comfortable levels.

yeah, that setup sounds like the one for you.

16 cells, and that speed is fair easy to achieve.

because i have packs of 7 cells now and i'd only need to add one more cell to each of them plus i would still be able to use my MRC dual charger.

Do you think my maxx would hold up to the 9XL on 16 cells? So far i have added...

UE 6 diffs
MIP CVDs all around
Single speed trans with steel ideler gear + FLM half case.
Hi Tech ultra torque steering servo
RR slipper clutch

it should last but i would recommend upgrading to the strobe slipper

Any other suggestions guys? Before i buy. :)

Am i going with the right motor?

The mip may hold. I have seen them break. I like the ue much better. But that can come later. That motor is good. I like it. It gives me good run time and great power. especially on 16 cells. 18 51 gearing on the strobe works well. !6 51 give you a little longer run time.

coolhandcountry... are you using this setup? Got any pics of it and how fast do you think it will go and hows the torque?

I run a 9xl with a 9920 right now. I have ran it from 12 to 20 cells. 20 seems a bit much. get a little warm. I have some video on the net to. www.rcpics.net/members/coohandcountry
this should have a video. Look up in the forum under extra long gmaxx I think itis.

I've bent MIP CVDs on a 7XL with 14 cells. Depends how you use your truck though, I was been abit crazy.

That link comes up as ...Your search did not have any results.

Got a link to the UE's that fit the stock maxx? I found 2 pins missing on the MIP's

This should work then.
