I think I fixed the temp problem. I used the settings HSN: 3 3/4 turn out, LSN: 4 turn out, Mid: 1/2 turn from flush.

I start the motor a little lean on the HSN, I let it heat up pretty good then set it to these settings above. I take it slow around the track for one lap and it is good to go. I ran two tanks through and the temp were 262. The key is to let the motor warm up really well then set it to these settings. It may sound rich, but it has enough power to carry you through jumps and tight turns.

The buggy is durable as hell. I have had some tough landings and it did not blink an eye. The Matrix is solid as a rock.
