Opinions please?

I would really love for you to try it on the 5s. I don't have a MM or I would try it.

But.... 4s is plenty if you are building a full on racer. 5s just adds weight and you wont use the extra power.

The I have both the 1515 and 1512, and the 1512 pushes my trucks just as well as the 1515. I can't really tell a differeance in the torque. You cant use all the torque that either one makes. Just get the 1512. Its cheaper, its more than powwerfull enough and its lighter. All good reasons in my book.

The 1512-2d seems like the PERFECT 4s motor.

I run the 1512-2.5d on 5s and its ridiculous. I actually like it much better than the 1515-2.5d I also run on 5s.

The middle comprimise motor would be the 1515-1y. At 2200kv it would be plenty fast for a track on 4s and still able to run at silly speeds on 5s. Thats the Motor mike runs in his emaxx. He runs it on 4s for racing, but I saw him run it on 5s when he was in the area for a trade show and it was amazingly fast.
