Ultimately the RC hobby (no matter how much you may spend) will still be FAR less expensive than the 20-yr old blonde!

That's all I have to say about that!

+1 to that statement; hence why I've stayed single all my life (through choice, honest).

what gearing are you running and how is the mesh. WHat size pinion with the 51t gear do you atleast need to use for the mesh to work.

52t mod1 Associated gear and a 17t pinion.

Thanks for posting that Neil.

Sorry GorillaMax360, I have not checked this thread in a while. I was worried about the gears meshing because of the Neu hitting the tranny so measured the distance between the tranny input shaft and the motor shaft. I then used Brian's gear calculator to come up with the gears. I had to use the Associated gear because I still have the stock slipper. I have a stobe on the way so i may try some different gear ratios in the future.

Here it is: http://scriptasylum.com/rc_speed/_gear_calc.html

I got a chance to do a little bashing today. Sorry no vids but some teperatures for those that have asked.

I ran 4s1p 4900mAh batts until the LVC shut me down. Ambient temp was 87F. Gearing is 52t spur and 17t pinion.

With a body with vent holes:
motor was 127F
esc was 105F

Without a body:
motor was 126F
esc was 103F

my Neu

Those are excellent temps. I would say you could (if you wanted to) go up at least one or two teeth on the pinion- that shoulf give you abit more topend & equalize the temps between the motor & esc (motor will come down a touch & the esc will go up a touch).

Nope, Neu's are not Feigao motors... they do not get cooler when you increase the load, they progressively increase in temp, and the ligher the load and higher the rpm, they run cooler. And they are not picky motors like the Feigao motors, there is no optimal loading that has to be found. Just gear for what speed you want and keep the temps in check.

I did not know that either. It is plenty fast right now. I may try a few speed runs with different pinions.

Mike sure does know his motors. I explained to him my truck, my RC experience and what I wanted. He recommended this motor. I couldn't be happier!

with a lower total overall gear ratio should i expect less temps from the motor or more. for example i want to run a 49t spur gear and a 20t pinion but i have 1/8 buggy diffs instead of stock maxx (ratio) diffs. with the same calculations as mkrusedc except different diffs and spur and pinion my ratio comes out to be 13.95662 : 1 and his setup comes out to be 14.99346 : 1. does this mean i can expect hotter or colder temps out of my Neu. and if so would it be a small change(like about 10 degrees F).

That much of a small difference... your driving style will have more of an impact than that. It could run cooler, or it could run warmer, I couldn't tell you.

But under the same driver, virtually nothing as far as temp increase. You probably wouldn't feel a difference as far as temps goes.

Damn cheap feigaos, they've ruined my logic & sense of reasoning.

Yes, when I came to the world of brushless, the fact the way the Feigao's act as a motor was just so alien to me... they are simply cheaper motors, which at the very least make your R/C move, and move fast might I add.

GorillaMaxx360 was asking about how well the Neu fit because of its size.

It fits flush against the smaller side of the GorillaMax single speed tranny. I originaly tried my Neu with a MM. To prevent cogging I would need the smallest pinion that would fit. I also knew I was going to have to use, at least initally, a stock slipper with a 52t mod spur. Using Brian's gear calculator and measuring the distance between between the motor shaft and the input shaft I came up with the smallest pinion that would mesh, a 17t.

Here is the mesh seen from the rear. I used the "put a piece of paper between the gear" to get a good mesh.
