Max Climber allows you to use a stick pack instead of the weird shaped TLT-1 pack. Because of that it uses a SUV body instead of a pickup body. You can build your own packs for the Rockbuster though that are configured like a saddle pack with 3 batteries up front and 3 in the back.
The Max Climber has black chassis plates instead of silver and red chrome wheels instead of silver chrome.
I was debating about getting a TLT, just wanted something to play around with outside (its a lil to breezy to fly my micro heli, stupid desert! ) but then i saw a video of the PTI MMT, and i think im going to wait til the PTI truck comes out
