I am guessing the V-Droop will be around 19.5v with this truck at 70-80 amps, as I geared it a little lower (13T from 15T), and it is lighter than the Maxx truck as well, so taking that into consideration. The runtime should be around 15 mins, as it was at least 30 mins with 2p pack, and geared higher, and heavier.
I will get it finished tomorrow (when heatshrink arrives for pack), I will post some pics for sure! 
Aqwut, unfortunately I don't have my Sony Cybershot anymore! (video capable)  I traded my sister for a Canon Rebel SLR, which is what these pics were taken from. |
Yeah I'd like to see what it does, tho I thought the A123s were rated for 70A max discharge according to the spec sheet. I draw 120A+ from mine (2P), and they get to ~110F as the pack dumps, so we should see. That's fairly close to max and they are not getting too warm. Truck looks great tho
