I got my Li-Po's in today, but I started worrying if 20c was going to be enough for the MM system. So, for until I get an e-mail back from Castle Creations confirming or denying these batteries are enough, the stock VXL system is re-installed.
For those of you here who don't have Li-Po on these mini's.. you're missing out.
A 2 cell Li-Po is the PERFECT power for the VXL system. You get GREAT wheelies but not so much power that you have to worry about flipping it with a blip of the throttle. I was actually able to maintain a long wheelie on the wing until I hit a higher spot on the road and went cart wheeling.
Also, if any of you are experiencing weak brakes.. re-program your ESC. I did after putting it into LVC mode for the Li-Po.. and did a front flip the first time I hit the brakes. I didn't get it to do it again after that, but they work lots better now.
