OK, Here's an update: Finally tracked down my control issues to a receiver going bad, by going piece by piece swapping parts with my kid's vehicles. With the receiver from my son's Fury installed, it's glitch free. Unfortunately, I thought I had the receipt in the box, but can't find it. So, no warranty coverage... Time to look up new receivers, but may buy a new radio setup instead, since Arrma's receivers are not much less than some new radios... Although, I do like the radio it came with...
Next Report: I installed this Turnigy 3900Kv motor:
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=72275 Not a bad motor for $30 delivered, except it cogs from a stand still. Not horribly, but having any low throttle "finesse" is out the window. And if you like to do reverse to full forward stunts, it doesn't do it. It cogs bad enough the ESC cuts out until you let off the throttle and grab throttle again. Once it has a little momentum though, look out. Rolling 10-15 mph and gunning it either results in massive wheel spin or wheelies. Motor get hot though. I have it geared 13/57 (32p gears) and after 10 minutes of bombing around on the street I couldn't touch the endbell for more than 3-4 seconds, and the ESC was barely warm. I wish I could find my temp gun...

Time to locate an 11t pinion, I guess.
Managed to pull the lower rear shock mount screw out of the control arm... ugh.
I need to open the front shocks and put a longer spacer under the piston. Really need to drop the front a bit more.
