Hello all, I am looking for a motor by Feigao - must be in purple color - that is equivalent or similar in power to the Mamba Max 4600kv or 5700kv. Any suggestions are welcome.
If it helps, I will most likely be using the Mamba Max ESC. Thanks. :)

why dont you just sand off the anodising on the casing of the mamba max and then colour it puirple if thats what you want. The reason i say this is that feigoa dont sell motors similar to castles mamba's.
The closest thing in size is probably the 540 8s but this is heavier and has a larger rotor and probably pulls more current than the 4600.
I have this motor running on 3s lipo and it is a challenge to keep it cool as its not that effcient especially at 50k rpm.

I was looking at this.

I think its cheap and in Kv what you whant.

aurell, that motor looks good in the kv area, but that's about the only thing I know about brushless motors.
chilled, how about lehners? Would their 4200 be similar? I would need another ESC though right? :confused:

The lehner basic 4200 would be fine with the mamba max ESC. It's also purple. The lehner basic cans are shorter than a regular 540 can as well, but are plenty powerful.

The Lehner 4200 pulls 55 amps, and the Lehner 5300 only pulls 60 amps. Both can be used and won't come close to the MM esc"s rated current. Those motors are awesome. 700 watts and they are shorter than the MM series of motors. Then there is always the Lehner 1920-6 :D . Any of those would fit the bill nicely.

Thanks guys! What's the difference in torque and speed between the 4200 and 5300?

Also, will the 4200 or 5300 run on 6 matched cells? :confused:

On the same cell count (and yes they'll run on 6 cells; I think the max is around 10 cells for the 5300, and 12 for the 4200 if you go by the "under 65k rpm" rule), the 5300 will be just plain more powerful because it'll be able to draw more amperage (more torque), and it has a higher kv under load (could translate into more top end). If you up the voltage, the 4200 is probably a better option. Since you're looking primarily at 6 cells though, I'd say just go for the 5300 for pure insanity, and the 4200 for a little less insanity.

Don't go by "the 65K RPM" limit. Stay around 35K to 40K to keep the motor nice and cool as well as in the efficiency range.

Thanks guys! Lehner 4200 it is then! :D

I know. I'm saying the upper most limit that you probably shouldn't cross is about 65k because of the rotor's chance of exploding from the centrifugal force. They're way outta their efficiency range on those cell counts.

I could strip off the green and paint purple annodizing on a Mamba motor for you?

What about pink....just to make people feel even worse that they were beaten by a pink motor...:D

Ahhhhh.... sweet idea!
Mamba Max will now have a pink annodized ESC heatsink and pink annodized motor!
Are there any pink snakes we can model the packaging to?
