Running 4S on a Mamba Max - Neccessary Mods

[rawfuls]

I will be running a 36-50-3300kV 5mm shaft v2 Medusa, if the deal goes through! on my Mamba Max, going to have to pick up a fan as well, any cheap ones?

I know I need a External BEC, and I have the 10amp, castle BEC, and I will just remove the red pin, and tape it, so if I need to use it on something else, it's always there.

Will I need a cap? I read a thread, where someone (I think BrianG) recommended a 2700uF Cap I believe, and this was the link:

Anything else that's recomended?

Let me know guys!
I'll be using my 2 2s 7.4V 5000mAh Turnigy's and my 2 2S 7.4V 5000mAh TrueRC Hardcased on this.

you dont need a cap, but it may help keep your amp spikes down.

And if I didn't use it, what are the consequences? :)

heat issues most likely.

Oh joyful.

Anyone wanna recommend a large fan for the MM? And not a 120x120.... mike..

I recently re-wired my CRT.5 which uses an MM and Lehner 1930/7 on 3S FlightPower 25C 3700mah Lipo.

Originally, I had it wired up with a Novak HV-Maxx capacitor. I believe the specs are 25V and 2700 uF.

I am also using a Castle BEC.

After my re-wiring, I forgot to install the capacitor, so I was running the same setup without the capacitor (shorter wires though from motor to ESC and some other stuff though).

My temperatures were noticeably warmer. I never temp'd the ESC before, since the ESC would at most get very warm but never too hot for me to touch. Now, it hits 130*F in only 4-5 minutes. I have stopped running it for now unti I re-install the cap.

Oh, wow, and you're only using 3S... definitely will use a cap, how do I wire it up?

If I toss two, or three caps on, will it reduce the temps more?

I ran a MM and feigao 8l on my hyper 7, no caps. just a ubec. And I had a 25mm fan behind it. It didnt get awfully hot, but it didnt die either. I did so on 5s and 4s

Sell it and get a MMM. Or wait for the MMPro to be available.

[rawfuls]

25mm......
How about those Novak fans that come with a Novak Power Boost Kit?

Those are pretty small, and I have one on my MM in the Rustler, that I'd like to keep there.

[rawfuls]

I would, but I need it for my Evader!

And no Mike, I'm not going to put a MMM2200kV combo into my Rustler, like what you did!

Just run 3s with the 3300. 4s will be too much for the esav.

[Gee]

Here's where I got my last batch of fans from. The price has went up slightly since then, but still cheaper then the Novak.

Also, get a servo extension and pull the red wire from it instead of the MM. Pulling the wires sometimes damages the connectors so when you go to put it back in. It doesn't "Click" and stay like it should.

Send me a pm with you address and I will ship you a cap.

[rawfuls]

Oh wow, sweet.

BL_RVO, I think I'm going to be sticking to 4S, with maybe 2WD, but will try 4WD at first.

If I dont' like it, I'll pick up a couple 3S packs, I don't want to not use 4 2S packs..
