Thank you for your thoughts on the front diff vs spool Oldfart and mrjudd. I think I will try the front diff with 300k fluid. Wouldn't you know, tqrc is out of stock of 300k fluid. Being in Canada, every time I order, I pay $30-$50 in shipping, so I try to order everything from one vendor to reduce shipping costs. Looks like I'll be ordering from two different places again...doh!
Mrjudd, what radio are you using? I have been using a cheap Turnigy 3xs, but just ordered a Spektrum DX4S yesterday. I felt the cheap radio was creating some issues. I realize there is a love/hate thing for Spektrum, but I have a bunch of Spektrum receivers already, so I thought I'd stick with the brand.
