HELP! Need a quick answer!...

I have both the Neu 1512/2.5D and the Lehner 1940/7 and also a Neu 1515/2.5D (not the same wind as you are considering)

I have run all of them in my revo. To be honest, the 1940/7 is my favorite motor of the 3. Its is one freaking wicked motor. Of the 3 I have its also the highest KV rateing so that probably hase something to do with it. :018:

Dont get me wrong the Neu motors are just as nice. I think the 1512 size is more than enough for a Revo. I am actually running my 1512/2.5D in my revo right now and its an awesome little motor. On 4s is a great track motor. PLENTY of power. on 5s it is a serious powerhouse also, great bashing fun.

If you go with the Neu because they are local and easy for any service issues that may occur (that is a big consideration) I personally think that at 1512/2.5D is more suited for a 40mph setup with the longerst run time than the 1515/1Y. Any of these 3 motors will easily be able to be set up for 40mph on 4s with no problem, its just a matter of dialing in the correct gearing. But, the 1512/2.5D will draw less amps and have longer run times than the 1515/1Y because its smaller and a lower KV, and the 1512/2.5D is still more than enough motor for your target with more power than you tires can put to the ground.

Go with the 1512/2.5D for the best run times with plenty of power. Go with the 1515/1Y for the most flat out power (biggest motor with the highest KV) sacraficing some run time, and go with the Lehner 1940/7 for the middle setup.

BTW: If you are ordering right away you wont get the Lehner. Mikes been waiting for a shipment from them for quite some time now.
