Motor:7xl or NEO

But your going to need a strong slipper!

I would get a strobe slipper...and depending on the motor you choose...you can run a 16, 18, pinion
with the 51t spur


Bl E-REVO
Quark 125b
Castle Creations-Neu 2200kv motor
((2s2p)(4s)
7800mah 7.4v Lipo Pack
E-Revo 1/8 scale Hyper 7 CD

45-50mph is asking a bit much from 12 cells. Speeds like that are usually attained with 16+ cells.


SH Z-Car, Custom Crawler, 8s Savage, 12s XTM XLB 1/7 buggy, 4wd 4-link rear/IFS Pro4 truck, Custom Hyper 10 Short Course, Belt-Drive Mammoth ST 1/8 truggy, 4s 17.5 MM Pro HPI Blitz

I have a hard time seeing a 11lb truck go over 45mph on 12 cells. Maybe with a Neu, but still... 40 is concievable, but I wouldn't count on much more.

Best bet would be to up the voltage 14-16 cells, or better yet 4 or 5s lipo. A neu (2200kv, 1515, 1Y) would def take you there then, and so too should an XL motor like a 7 or 8 (if 5s). Can't comment on the Neu 1512's. Obviously this is dependent on your exact setup, but should be a close ballpark.

Twin 700 motors must add a fair bit of weight anyway. I wouldn't run a 7XL on 12 cells, it aint pretty!

On a truggy, I wouldn't run less than 14. I would run 16 or more, but thats just me...

Going 50 mph plus is not that hard on 12 cells. I've done it will a light weight E-maxx running a Basic 3100XL and a 7XL (No not at the same time:027: )on 12 "good" cells. This was using very high gearing.
For your weight truck I would use more cells to meet your goal. It will be a much better setup than trying to run 45 to 50 mph on 12 cells.


Thank you,
Promod

There was also a guy that used to post on the old maxxtraxx board that ran over 50 mph with an 8L on 12 cells.

Thank you,

Squee, i don't know what you are talking about??

You said something different i thought. I read that post of promod ages ago about the 50mph on 12 cells with the XL3100.
