Brushless Power for the Durga! Help needed
 

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)...

The Mamba Max esc fits on the Durga?

Just like to point out that the mamba isnt BRCA legal :) its a very good system and is very quick and adjustable though, what ever you go for you wont be dissapointed.

I've ran the 5.5 Vortex Orion and Lrp combo w/no problems (16/91)

Mamba ESC fits easy peasy!

the Mamba speedo IS legal, the motors aren't

I just started running the R1 and Redline 632 motor (6 turn 3.2Kv) and it goes well, the motor is designed with lots of torque, so I just keep gearing up.

Allright thanks guys!

I won't run any races with it as there is no track in the near. And if I run on a track it would just be running for 'fun' not a real race. So the thing doesn't have to be race legal..

Would the 23T pinion and stock spur do allright? Also would other spurs (from other manufacturies) fit the Durga?

Why aren't the motors legal?
Any suggestions for a legal alternative to go with the mamba esc? Or was that the R1 and redline motors you mentioned DCM?

The mambamax combo is ordered! In the end I went for the 6900kv. It is probably to fast for me in the beginning', so i'll limit it using the software.

I thought the 6900 is more "futureproof" then the 5700 for me and as I won't run it with 3S lipos (which is the only avantage from the 5700 over the 6900) the 6900 was better overal.

After spending a week at Customs my Mamba brushless combo is on his way to me ! I hope to receive it tomorrow :D

I have a question though: I'm thinking of running it with the stock spur and 19T pinion. Would that be sufficient? The 19T should keep the motor and esc cool is that correct?

The motors arnt legal because the BRCA havent passed them, there not rebuildable and the internal dimensions apartently dont match the BRCA regulations. The peak/vortex motors *should* run on it, especially with the new firmware but with the old firmware i couldnt get my vortex motor to run at all. Great speedo's though.

I just received the Mamba Combo , had to pay 43 euros for tax and customs though ..

I'll fit the snake this weekend and I'll keep you guys posted

let us know what you think. I know I'm pleased with mine;)

Ye, id love to know how it goes in a 4wd, you will be amazed at the amount of torque you get out of the rev range if you compared it to another similar sensored combo, there great for stuff like that :woot::thumbsup:

Mamba Max on the Durga
 

Hi guys!

I tried the mamba 7700 on my Durga and the Speed control blow off...

now Im running a mamba max with the 6900 motor and the velocity is absurd... I had to limit velocity in my radio to a 80% to make the buggy more driveable.
with the 6900 the 17T pinion goes very well.

I like to see the face in the Nitro guys when the Durga surpass 1/8 buggies...jeje its awsome!
