I just recently picked up a CRC Gen XL. I looking to find out what tools I would need with 1/12:

Droop Blocks
Droop Gauge
Ride Height Gauge
Tweak board, etc.

Also we will run 10.5 brushless or 19t brushed at my local track. Is there much difference between motors for this class? I am thinking of going Team Orion 10.5 Vortex (new can) as far as esc I am thinking Tekin RS as I can pick those up cheap used. I just don't have the 2-4 weeks to wait for the Xerun 120a 1s to ship.

Now I do have the receiver pack one dynamite 180mAh 2s 20c 7.4v and Protek RC LiFe 6.6v 200mAh. Do you need special charger to charge LiFe packs?

Thanks in advance for all help!
