My Granite Mega is holding up fine to 2S LiPo power, when something unrelated to power isn't broken on it. I've been running nothing but LiPo. Value Hobby G-Force 4000mAh.
Interesting that your slipper plates were glued in. Mine weren't.
Than Arrma should give you a BLX truck to congratulate you with the only 15t stock motor, which has survived more than 10 lipo packs
I had 3 of those motors, and all did not last more than 2 or 3 runs.
And the line of users with the same experience is long!
This was the last of the motors.
The black powder is actually what was left of one of the internal brushes...
I used 6000mAh 50C 2S by the way, but that should not make a huge difference.
Would make an interesting poll on this forum by the way
I had a 2011 MEGA Mojave at first, which did not have the plates glued in.
Both my 2013 2x BLX Fury and 1x MEGA Fury do have glued in plates.
The ones I ordered I did not glue in, and work fine even after a year of use.
