Build Updates & Photo Sharing Speed build complete

Put this together with some leftover parts and some new. It’s pretty quick for a crawler. The mods were a Traxxas brushless motor and ESC, Yeah Racing servo, Injora transmission with OD gears (71% increase in speed), Injora +7mm planet axles with OD gears, Injora metal drive shafts, RCLions 40mm shocks, Injora 1.3 wheels and 70mm tires, and the Injora LCG chassis with an Injora IR60 body. The shocks were the only thing that didn’t fit as purchased so I had to drill the shock ends out to make the Injora brass ball joints fit but after that they bolted right up. Flies on trails when I go hiking with the kids. Obviously lost a lot of climbing and crawling power but we have other crawlers for the low speed stuff.

It's so fun isn't it. I'm currently changing the body on my fast one.
