I uploaded the vids to youtube so that I could reach a wider audience. There is also a new vid of the truck using 14cells; not as impressive as I was hoping.


older vid


New vid

I did remember to bring my temp gun this time (aka hacked meat temperature probe, oh man....), the results after 10 minutes of hard running are as follows:

ESC= cold, seriously. Wasnt worth checking it was so cool ~ ambient temp 20*c / 70f ish.
Batteries= hot! ~ 70*c / 160f ish
Motor very warm = 60*c / 140f ish

Normally I would say that the motor was under geared, thats why the esc is so cool yet the motor hot. Thing about the HV motors is that they dont always follow that rule of thumb, so I think I need a few more pinions (18 & 19tooth) to have a play with, and try gearing up a little. I will figure it out though- I know this system is capable of much more; it went faster in the TXT-1 and that was with the old bonded rotor and 12 cells.....
