Good idea? - 09.10.2007, 11:03 PM

I was on Brian's site looking at the motor spec's

And I know cem is using the 10L in his crt.5

So I looked at the specs and all

And then looked at NEU's

A NEU 1512 is 1MM longer then the 10L, and its a little bit bigger in dia


Is that simpily too much motor for a EXT crt.5 with 30's series tires and al the goodies?

On 2s

Well, it really depends on how many cells you are going to run. Right now I'm running 4s with the 10L (actually still need to make a batt tray and get the pinion, been wrapped up in school lately...) If I was going for a higher quality motor I think it is a tough choice between the 1509 and the 1512. Honestly I don't know which one I would pick, maybe one of those KB45's lincpimp just got...I'm leaning towards the 1512, but I like lots and lots of power....

Bye

2s..... I want to run a trak power gold pack, 2s, 20C, and its 4900 MAH

I want the 1512 I think, just making shure im not over doing it LOL

I want it to run cool,and I also like lots and lots of power

The 1512 is waayy too much motor! That is huge compared to an L or S. Unless of course you actually want to be rebuilding diffs all the time!

It would be on 2s though


It isnt much bigger then the L can, going by your site it wasnt.......

For 2s I would go with the 1509. One reason being that a 1512 will pull more amps and have less runtime compared to the 1509(considering geared for same speed) and I would want to keep things on the lighter side. The 1509 on 2s will be pretty light and nimble and make for an awesome race machine if you ask me...

The 1509 1Y I believe it is, has 3600 kv

I just dont want to run hot

On 2s, and the 3600 kv, geared 15/46 I would be getting about 35 mph on 30's series size tires

But running hot would STINK

Hey BlackedOutREVO
Would you be interested in a Plettenberg Maxximum? I am trading my crt.5 to Metalman for his Revo so I am not going to have a use for my Plett. I only have about 5 runs on it. Send me a PM if you are interested.

It's not much longer but it has enough power to easily power a 8th scale buggy and could even drive a truggy. You might actually underload that motor unless you gear VERY high. Using low voltage on it would help I guess, but still think it's way overkill. Someone else put a smaller Neu (can't remember which one) and it ran quite well - and it ran good on the MM.

IDK, I dont have the cash now, it would be more around Xmas, so probably no

Ibjammin ran a 1506 I belive, its a MM size motor, but high quality

I want motor, and running cool on 2s

I think the 12 is out though, thats alot os motor, and power hungry, I want some runtime too

I just hope it wouldnt run hot

Frankly, they are very similar in design compared to the novak motors, but Novak is one step ahead of neu and uses sintered rotors verses the bonded segmented rotor that neu uses (that novak used to use). If you want save money, you could also get a novak velociti. These motors are so efficient, all you have to do is chose your wind for power instead of the size of the motor. You can go all the way down to 3.5 turns with them and granted it will do 35 mph and not overheat. Now, if you could fit a feigao rotor (which is sintered) into a neu can, that would result in ultimate power and efficiency.

Not to be a prick

But there is no way in crap that a novak is nicer then a NEU...... I have ran the novak 13.5, and I blew it in half racing it, yess wierd and doesnt happen much, but there motors are built with cheap screws, and the can is cheap alu

So I bought a Team Orion (the new vortex line) 10.5, and the screws and the can is MUCH better quality, and it even has a cool little internal fan, and it has a sintered rotor

NEU it is, I wont do a novak, or any sensored bl set up, I dont think it would run nearely as well as a sensorless NEU, and MM combo


Just IMO though

i deleted my post, but I was merely using the novak to prove a point that it is better to choose your wind for power instead of the size of the motor. The novak's are a good example of this because they are known to be very efficient and they are very similar to the neus in design internally with the exception of being two pole motors.

Thats no good

Because if you choose wing over size, and you have a motor thats a S can long, thats no enough torque, longer can means more torque, and the NEU 1509 would be in the middle of L/XL

What im saying is that it might be better to go with a smaller motor such as a Neu 1506 and use a higher kv than you would if you were to use a 1509. It generally takes more power to just to get a bigger motor running, and when you are not taking advantage of its physical capabilities, it will be less efficient and less powerful than a slightly smaller motor. By that, I don't mean running it until it's overreving, but 7.4v x 3600kv with a 1509 1Y is wasting a lot of potential power because its not spinning as fast as it could. Good brushless motors get more efficient as you increase voltage. A 1506 that has 5400 kv will have about the same power as a 1509 1y, and be more efficient, thus running cooler. Apparently, you are also worried about torque. Find a pinion gear that is 2/3 as big and torque will be the same as with the bigger motor.

I see what you mean

But I can get a 1509 in higher KV's..... So I can get more rpm, but I dont want any heat issues

a 1506 has been used... But I think a 1509 fits the bill better..... I have RCM Mike help me out, and that motor is what he said, but I wanted 3s at that time..... But still
