Will this fit in an arena granite if not what do you suggest that's high performance ???
A 1/8 scale system with a 4068 motor can be installed in the Granite. You will need to adjust your gearing to compensate for the much larger motor and monitor your temps carefully. If stock gearing is left unchanged, thermal failure will likely occur.

Real quick. Would you recommend this in a tekno mt410? I’m new and this is my first build other than rtr. Would you recommend something different?
Hey Brandon,

Nice choice for a first truck!!
This combo will work, but you may as well run the combo with the 4076 motor. The 4076 is slightly longer and builds more torque that come sin handy on MT's. What voltage do you plan on running? If 4S then the 2200KV 4076 is a good option, we do have a very good quick read on motor setups and operating items that is worth a look for a good synopsis of setting these systems up for good performance and long life: https://www.rcjuice.com/power_system_setup
