Ok... I made another 'test' run today with two packs... the first was not fully charged, but it had enough get the motor turning well. It's quick and smooth on power... breaking was excellent...
stopping was noticeably easier with the 1520... temps on the motor went up to 120° F and the esc 122° F (no heatsink)... I think I got about 5 minutes of WOT run time with this set of batteries...
with the 'fully' charged packs I got 10 mins WOT... I pushed a lot harder with these cells and saw that this truck will be a handful when I finally get some lipos for it... I was a little aggressive with
the throttle and brakes just to see how hard it could be pushed... the temps of course were a little different... 137° F for the motor and 135° F (still not heatsink).

Here's the setup:

Differential Ratio: 4.3
Transmission Ratio: 1
Other Ratio: 1
Spur Tooth Count: 51
Pinion Tooth Count: 15
Total Voltage: 18.5
Motor KV: 1600
Tire Diameter (inches): 5.65
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor Coil Resistance: 0
Spur/Pinion Ratio: 3.4 : 1
Total Ratio: 14.62 : 1
Tire Circumference (inches): 17.75 inches (450.85 mm)
Rollout: 1.21:1
Total Motor Speed: 29600 RPM
Vehicle Speed: 34.03 mph (54.67 km/h)
Effective KV Value: 1600
KT constant: 0.85 oz-in/A

I think when I finally put all back together, i should be able to gear up a tooth or two. The temps on esc were really good and I was quite impressed it had no thermals running without a heatsink.

Continuing with the experiments... I was getting a little concerned again about the temps and them getting higher when I eventually switch over to lipos.... so I decided to make some changes
with ESC setup and pinion to see if I would get better results... and I did... I remembered when I was first testing the hacker, the 'Torque Selection' was change from 'Soft' to Dynamic Initial Torque'...
So I went back through the Quark programming and changed the initial torque to 'Normal 1', one step above 'soft'... I swapped the 15t pinion for a 18t just too see what would happen... this motor
had so much torque I assumed it could handle the gear up... I was not wrong about this, The motor showed off what it could really do with it's power and pulled the truck just as hard when it was fitted with the
15 tooth... Very impressive to say the least... the temps were also surprising... the esc only got to 112° F (well it had some help from the heatsink)... I thought it would have been much higher with the
larger pinion... the motor stayed in the high 120s

I'm going to run it on 5s tomorrow and see it goes... going to also try and get some vids done too (good quality I hope).
