Arrma Granite 4x4 Mega Monster Truck RTR (Red/Black)
I bought this truck for my 10 YO son a little over a year ago. The truck itself is incredibly durable. But do yourself a big favor and buy the 3S brushless version - it’s more than worth the $80 price difference. We burned up two factory brushed motors in less than a week trying to run it on a 2S LiPo. I put a Titan 12T motor in it and never had another problem (except for 2 stripped spur gears). My son quickly outgrew the speed of the truck though and we ended up putting the 3S brushless drivetrain and electronics in it (about $150 in parts from a chop shop). In hindsight, I should’ve just bought the brushless version to begin with and saved money. Overall, though, this is one of the toughest trucks Arrma builds, in my opinion. The light weight and short wheelbase make it virtually indestructible. The only thing we’ve broken are 2 control arms (and one was from me rear ending him with a 6S truck at 40+ mph) and worn out a couple of bodies. The shocks did leak almost immediately as well, but have been fine since I rebuilt them with new o-rings. Great little truck that can do it all!

Arrma is a great company, love their products....but...the granite 4x4 mega...they say this thing is compatible with 2s lipos. Well, after putting it in lipo mode, it over heated after just 10 minutes on pavement. My traxxas slash sitting right next to it is brushed and has been run hard on lipos, never had any issues with it. Anyways, I have only had about 15 minutes of run time in 3 weeks of ownership because the radio has a terrible delay, the trigger sometimes takes doesn't respond, and I get about 30 feet of range. The STX2 is horrid. I've also noticed some clicking coming from the truck on acceleration. Sounds like gears slipping. With only 15 minutes of puttering around on pavement, you would think there wouldn't be any issues. Kinda wish I would have ordered something different.
