Mamba Max fan mounting

[Mike.L]

it would be very hard trying to tell someone to make one for you with out laughing......just like trying to order over 10 cheese burgers for 2 people hehehe dom:)

lol you guys:p

I actually need a fan on my Mamba Max. However, it is being used in my Revo with a 7XL and 5s A123. Without the fan it would thermal in a couple minutes, even with unrestricted passive cooling (no body). The fan has dropped the ESC temps about 70 deg. F, which is plenty to keep it from thermalling.

But still, that is pushing the esc over its limits, 5s in a revo (heavier than mostly all the ST/buggy/etc.)

dom, i was amazed when you had that super fan, it was loud as a hairdryer!

metalman,
what size or kind of fan are you using that drops the temp that much? I plan on running my mamba on 5s in a losi 8ight with a 9xl c can and think I might need a fan.

It's a 40mm 5v fan. Unfortunately they are sold out at this point.

I'm still a fan of function first! I like my stuff to look good but whats with all the flashy lights?????

And why do people need 24" wheels on their family sedan? Ever seen an evaluation on how much braking force is lost on a 20" wheel when installed on a car designed for 15" wheels? Pretty Scarey!

Sorry for wandering off topic...........

We now return you to your regularly scheduled program......

thanks for the link. good to hear that it made a big difference.

I dont see why you would need one, should run cool. If gering is anywhere near correct, the ESC shouldnt even get much more than warm. More voltage= less amps.

On a cool race evening (60F and below) I ran the Mamba Max without a fan and it was fine. Since I am using a 1/10 scale ESC on a 8 pound buggy, I thought it would be a good idea to use a fan. I am geared fairly conservative (less than 40MPH). Even if the ESC doesn't thermally cutoff in the summer, MOSFETs are much happier running cooler (their on resistance is lower at lower temps).

I haven't run the buggy for a little while. I have been back to my first RC love.... airplanes. The Mamba Max with a 4 pole motor (Neu) is a little to coggy from a start right now. I hate to be sitting at the starting line with everyone else half way around the track. I could put 540C 9L Feigao back on..... maybe when I flip flop back from planes to cars again.

my 4 pole pletty doesnt cogg at all on 5s.

That's good news. I'll be installing a NEU 1515 with the MM ESC on 16-cells(will probable start with 12 cells to see how it runs first)

Imo the mamba shouldnt be pushed at 5s or 16 cells.

I agree! it has not been tested enough to know the durability.

It does it better than 3s. And does it daily. 5s runs much cooler than 3s.
