Thunderpower-6.5 info needed.

[Lowie]

I raced 4wd this weekend and had some troubles with the ESC (Tekin RS Pro) thermalling out and having a very hot motor.
Unfortunatly my temp-gun has been stolen so I did not measure the exact temperature.

Is this Thunderpowermotor (540 - 6.5) an motor that has to get or does get easely hot?
Also, I looked on the Thunderpower-site but could not find any info there (for their motors). Does anyone know what rpm's this motor gets? I lost the little brichure that came with the motor.

I'm trying to figure out what went wrong this weekend. As said I thermalled out suddenly during last twoo finals in the last minute but gearing seemed OK, and Tekin should have been able to run this engine without probs.

thx in advance.
