Feigao 9XL Failure

[zeropointbug]

You have a 1515 size though, more torque man. You would prob need 5s lipo to bring it to the track with a 1512/3D.

I don't know if I am imagining things, but it seems to me that the Neu's have a more' precise' feel so to speak. Like they react very proportionally to throttle commands, much more so than Feigao's, at least compared to my 7XL. Anyone else find this?

That's the outcome of the quality difference :)

I just Had my 9XL Replaced and Ran it twice on 5s 5000mah 25c in an Inferno Gt with 777 Center diff MMM v2 esc 48tooth Spur and 17 tooth Pinion and it failed I was told after it failed that this is too much for these Motors and it failed becasue I used it beyond it limits if I do the math it was somewhere around 34000 to 38000 rpm I do not think this is too much for this but maybe it is please if anyone has any insight on this let me know
Specs
IGT, 48 spur, 17 Pinion, MMM v2 latest Program, 1 2s 5000 25c, 1 3s 5000 25c is series, 12 Gauge wire, Deans Connectors, Spectrum DX3R

As Far as Runs They were Street Runs a couple of Full Throttle Launchs but mostly roll on to keep the car straight to near full speed
Motor Had the RC Monster Heat Sink on it also Body windows were cut for air flow
Batteries, Wires and ESC all Cool only thing that got hot was the Motor

Ran a couple days ago was probably 40 degrees Ran yesterday was probably 55 degress when it failed

I was Happy with the power it had any suggestions on new Motors Like the Medusa and CC and Neu but want to stay at about same power anymore would be undriveable

The feigao motor is cheap for a reason.....

I don't think it was too much rpm. Its a bit on the high side for a cheap motor, but cert not more than others have done. Plenty of people have ran 7xls on 4S (about same) and I had a 8XL on 5s for quite a while. More likely bad luck, some user error, or driveline shock or something. Hard to really guess from your post.

I would replace it with a better motor tho, like a Medusa or CC neu or something. They are not that much more $$ and very very much worth it.

I did 6s life (thats about 5s lipo) with 9xl feigao. Added couple fans and didn't have any issues.. Even geared it to the moon for couple speedruns, took it very well. But other hand, im not a hardcore racer so can't say from that point of view..
