Hats off to you and Castle Creations. I'm sure this will be a huge success.
So the Fan kicks on at 140 degrees or so? Nice!

This will prolong the life of the fan for sure and also save a small amount of energy for when it's not needed.
What kinda air flow does the fan provide? cfm?
I'm very happy with your production schedule and the success you're having. My MMM is in RC Monster's second batch of pre-orders somewhere.
I have a 14xl that I would like to try in my E Revo on 6S. There's a few outrunners here I would like to play around with also.
There is a spot on my E Revo Chassis that is just made for your new creation!
Thank you for being so informative.
