Question for the Mamba Max experts

[streetdemonz]

I've been driving my revo with 12 3300GP cells, Mamba Max, and 8L and didnt disable the bec. It got hot (real hot)once when I went up like 6 teeth on the pinion and drove it in the basement(my ankle is still bloody:012: :012: :012: :012: ). But at 12/66 gearing on it, it wasnt really that warm and it was pretty fast. Mind you I do live right off lake Michigan and its freakin' cold out. Im going to test it today at the 16/66 gearing with a receiver pack and bec disabled. This is a budget setup. So far so good! I think I will make a video when the wife gets home also.

Has anyone let the smoke out of a MM yet? I don't remember reading about anyone has toasted one yet.


If someone has toased one, what setup was running when when it went?

[streetdemonz]

OK! I just ran it. I disconected the bec. Took the wabash and panthers off and put some Monster GT wheels and tires on. Running the 8L,18/66, and 12 3300gp with a RX pack. I beat the crap out of it and it got hot. Drove it in the back of my house and there are alot of ruts and weeds(no grass yet) it didnt shut down at all. The only reason I brought it in was the batts, esc, and motor/ rc monster heat sink were really hot. It got awsome runtime.

So I highly argree with everyone else. Run a UBEC or RX pack. Less heat = No thermal overload!! More fun!

Where can I get a fan for the mamba?

Where can I get a fan for the mamba?

I bought two (one for backup) for my Mamba Max. They just arrived today. I bought the Sunon GM0502PFV1-8.GN (Digikey # 259-1325-ND). For a 25mm fan, it moves a lot of air (3.5CFM). It is 5V so I will run it off my UBEC.
My plan is to use two #4 screws to mount the fan directly to the MM heatsink. The #4 screws thread themselves inbetween the heatsink fins perfectly (GordonFreeman posted the screw info on another forum).

Here is a picture of the Sunon fan mounted on the Mamba Max.
