I think I will go with the 7XL for now and upgrade later to the Monster Max.

What is an acceptable range of gearing? If I've read correctly, I only have the 46t kyosho in nylon for the spur?

Are the 7XL's hard to find? It looks like Mike is out of stock.

I wish the Monster Max had a date.. I cant hold out anymore with this CRT chassis taunting me! I can't wait to get this thing up and running!
