I really like the 1512 I have in my buggy. I'm sure a 1515 would run great but I don't know if you need it or if it's a good thing, esp if you want a lighter setup.

My car runs 8.0lbs fully rtr with the 4s 6000 packs. I've run it geared from rather slow 15:1 (10/46) all the way to 50mph-range 8.4:1 (18/46) in the street. On the track I've been running about 11:1 (14/46) which hits 30mph or so. My motor is the 1900kv. I think you can go up just a little in kv and still have a good range of gearing options. I would grab the 2000kv one if I did it over again. The 2600 is too high for me... for racing anyway.

Lower kv means lower currents... at the same voltage, and should be more efficient than the hotter winds. I don't know what happens when you gear the different winds for the same speed... that's the $64,000 question and I assume that's what you mean about the runtime going down.

I got rained out again from doing some playing around (errr... I mean testing ;) ) tonight... but I've been meaning to experiment with gearing some more. And get some video. Maybe tomorrow.
