I've got both and the 8 stays right next to the mm2 at all times. You can pick, either a set of losi 8ight Truggies converted to brushless(2.0 & 3.0); mbx6Te & mbx7te; or a set of Yeti XL's. They both run side by side and seem to keep the same temps, this was with full 3.8 proline sand paddles on all of them at the beach here a few times this summer. Think Texas costal heat.... No issues. Only issue that I've had is every now and then a screw will back out on the motor on the wire side. I probably need to loc tite them...
