NEW to me 210..looking for battery advice and more

[zleader]

I recently picked up a 210. I currently have 22 witch i run on carpet with shorty lipos in mm. The 210 I picked up is in mm. I was planning on running the same shorty lipos from my 22. I was planning on running them as far forward as I can.. With my 22 I was looking to add weight to front. Does the 210 need more weight up front. I will be running on a high grip carpet tight track.

I have read some info on people saying is a game changer running the shorty lipo on the 210.

Please any info or pictures.

I was planning on placing my viper esc centre line rear in the cavitity created by running the shorty way front.

Second question what gearing are people running with 17.5? The 22 it was a 5.3 or 34/72
