Ok took it out to test it out.
This thing has an INSANE amount of power on 4S. So much it actually broke 3 teeth off the hardened steel pinion gear I used in it.
Said I would take a video sorry for their quality, they were taken with the camera I used for the pics, and held in the hand I had my remote in.

The crash actually knocked the one lipo's connector off, moved the pinion forward, knocked the motor loose, and knocked one of the wires out of the battery connector on the lipos side. Amazingly nothing broke. I am so sold on jammin's durability only other RC I own that could take a hit like this are my savages

I've shattered more on 1/10th RC's hitting cracks in the sidewalk.

I stopped recording after this cause I didn't want to crack it up again.
Now to find a stronger pinion... Going to have to try my Novak 14t hardened steel pinion on it
