I got an Align 600XL to run in my 8ight T. I ran it on 5S and geared it the same way that I gear my 1515 2.5d. Keep in mind that our track is pretty tight so it's a lot of accelerating and braking, but after a 10 minute run, the motor temped at 200*F. My Neu never gets over 170*F or so after 30 minutes of running. Once again, you get what you pay for.
