Best Chassis, etc for a e-revo racer

[Serum]

One thing i must hand the bigmaxximum was it's torque. It's impressive, but it's got this nasty startup cog.. (that magnetic resistance that needs to be overcome.. ) how is that on the mamba-maxx?

I would make the lipo tray interchangeable and available in different sizes.. Future customers would thank you for that. All lipo manufacturers use different sizes.. (which is a true PITA when you design a chassis) i see you used Enerland cells, which is a good reference, but still; make either the batteryholder flexible in size, or make different sizes...
