Brushless Power for the Durga! Help needed

[Vin]

Hi all,

I'm running the Durga with a brushed (13T) motor. However the motor doesn't deliver enough torque. Instead of spending money on a new brushed motor I think it's more usefull to switch to Brushless instead.

I've read a lot of good things about Castle Creations Mambas and they are well priced too. I think the 5700kv version delivers enough torque and speed for me, maybe it's even too fast but then I'll limit it. I'll run it with a 6cell NIMH battery in the beginning, maybe I'll switch to lippos but that could take a while as I have to watch my budget....

Castle Creations has two different ESC's, the MambaMax and the Sidewinder. I hear good things about both and the Sidewinder is a bit cheaper. Which of these to ESC would you recommend or would maybe recommend another motor/brand?

Please give me your opinion, thanks in advance!

I'm running with a Maxx 6900.
Very fast with pretty good run times. Very configurable in the software.
Using basic ansmann 3700 stick packs at the mo. Will move to lipo soon though
Have you got a slipper? If you are moving to brushless I would say thats a must.
If I'm not mistaken, the maxx can handle more power than the sidewinder?

The sidewinder can't handle the 6900 and 7700. However it should start up faster etc. I dont know which one to pick... And yes, I have the slipper installed. Do you have enough torque with the 6900?

I think so. Certainly works the slipper hard from standing even though I have it set quite tight. Does suffer a bit from cogging. Though this seems worse on one of my packs so not sure if it's just naff batteries causing it. Certainly doesn't do it on my 11v lipo from my heli!!

I'll be putting the Mamba Max in the Durga for the next time I race - maybe the Batley Super cup, not sure. I have the 5700 motor - not really sure what gearing to go for but I'll let you know what I come up with

Let me know how she goes! Also what batteries are you using?

After watching a lot of Mamba 5700 movies yesterday I'm thinking I'll go for the 5700 with a Mamba Max esc (as the pc interface stuff is included there)...

Hi there,
I have the durga DB01 and recently I installed the Mamba Max 7900. I am running with orion 3300 Ni/Mh battery, 91T spur and 17T I installed it with the quick set up as instructions, fine so far. It worked fine but just for a while becauase my front and rear diferential (where the belt goes) Mashed!!
Now I know that Slipper Clutch is a must in order to handle such power. Will I need anything extra apart from the slipper, in order to enjoy my super fast Durga??
Thanks for your help

Hi,

I would advice you to rebuild the diff with the TRF metallic part (Diff Joint Item #51286).
After a big crash, I decided to check everything and discovered that the rear diff was showing signs of running quite hot (thanks to the Storm Evo 5.5)... It did not melted completely, as reported by some in the forum, but the pulley had slightly "melted" around the diff balls (ceramic one from Kanzen) and I noticed that the metallic plates were again moving freely (tried all the glue available on the market with no result).
Since the rebuilt, diff running smoothly and since it seems the TRF diff joint is longer than the Durga original part, the CVDs are well in place.

Cheers
