Quick update. (it's 3:30am... think I need to go to bed soon :) )

I have done a couple test runs with my 1512 1.5Y now... so far so good.

I put it on the track the other night during the races. Had it geared 10/46 and 4s lipos. It ran very cool but it didn't have much "rip" to it.... no top end at all. Geared too low.

So at home I tried 13/46 and it was better but still really impressed... so I grabbed the 18T gear I have from the emaxx tranny. Much better. :)

Wow... it's geared tall! But it seems to run great. I would like to try a tooth or two lower but don't have anything between the 13 and 18 right now.

With the 18/46 and 4s lipos it's fast... I didn't put the gps in it but it must be hitting low 40's, and plenty of punch. I ran a crappy 3s lipo pack and it was still pretty quick, just not as impressive, obviously.

Run #1... 6 minute nonstop street bashing (simulated racing ;) ) the motor hit 145 degrees and the Mtroniks was 115 on the case and diodes were 125 maxamps 6000s were 110.

Elogger showed peak amps of 75, average 14.6 and only 1544mah used. (I think it's conservative in the mah #'s... maybe add 20-30% ?) I did some long speed runs to see what the amps were like and it would go from 60 amps off the line down to 20-25 amps once up to full speed, FYI.

Run #2... 3s lipo pack for 6 minutes pretty hard. Temps: motor 110 esc 90 (barely warm) peak amps 67 ave 13.5

Run #3 I then did a run with a Mamba Max (w/ubec) and maxamps 6000 lipos, and got similar results to run #1. The car felt really fast on this run, but it was under street lights so that might explain.
9:22 run time minus about one minute of "down time", so about 8-8.5 minutes. Motor 145, ESC 140; 120 at caps, batts 105-110, front drive shaft 120 :) Log data: 2225mah used (over 2500mah charged back after the run) peak amps 77.5 ave 14.3

These runs are on paved street/driveway with bald tires. Peak amps and mah used will surely be higher on a high bite offroad track, but I don't know how much.

A guess would be about 100 peak 20 ave... temps we will see.... I can't wait to see what happens on the track.
