Neu 1515 2d on 4s and 5s

[Patrick]

One of the guys I race with has one on 4s in his Kyosho ST-RR. I think he has it geared 46/16 or 15. I think it was 16t (~40mph). It seems pretty fast out of the corners and down the straight, but it has also been staying very cool for him.
I'm not sure how it compares to the 1y (mines in the mail), but it seems to work well in a truggy, and would certainly be enough for a racing buggy.
Should be fun on 5s, without being to over the top.
