Ok, here is an update on my Mamba Monster. My first one is back in for repairs the second one I bought from my local hobby shop, so it must have been from a different batch. My second Monster had 80 minutes of practice time going into this weekend’s race. The fans on both of my Monster died within 20 minutes of run time. I’m luck my setup is based on 6s 22.2 volts because it runs cool enough without the fan. It was very hot here at Houston during the race 95F, so it was a good test for the Monster. I ran one practice battery for 15 minutes. And I ran three qualifiers each 5 minutes. I qualified 5th for the sportsman A-main. I also finished 5 in the A-main. The A-Main was a 15 minute race. The Monster performed awesome the entire time. It really took some hard hits too. If I would have had my suspension a little better I could have done a little better. The fan plug had gotten knocked off the bottom of the ESC board early during practice, so all this was done without a fan. I check my ESC temp. after every race and it was always about 150F and my motor was also 150F. I plan on drilling a few extra holes in the case next to the capacitors for more air flow and not use the fan anymore. Fans with dirt and jumps just do not mix they can not survive very long. The Monster also has a clearance issue on the bottom side of the case. The fan plug and the big black component on the ESC’s bottom side ware on the case. I think this is causing some of the failures. I am installing a very thin square rubber gasket between the bottom case and the ESC board. This will keep the big black component for getting hid on the bottom case on the big jumps. I’m really happy with the way it preformed this weekend and I should be able to win one of these races soon. It’s a tuff class of about 35 to 40 people. I’m starting to get some real confidence in the Mamba Monster. I think it going to be a very good ESC. Were just having a few first production bugs.

I will try to clarify. The gasket is to rise the ESC board up in the case so the components on the bottom side are farther away from the bottom case. Nothing should touch any of the components on the board. So the gasket is like a little rubber ring around the outside.

I also have holes in my car body next to the ESC so air is moving over the controller. That is the only reason I'm able to get by without a fan.

Very nice update, seems like you are having a blast with it. Some people have phoned CC about the fans and CC have sent replacement ones out to them
