Just a note that I tweaked the truggy a bit and did another quick midnight test run... trying not to annoy the nieghbors too much.

I'm guessing the top speed is kinda slow (I will check that tomorrow) but geeze this thing has serious torque. (Neu 1512 1900kv) Truggies are not supposed to pull wheelies are they???? :D

This may need a new thread... but part of the magic I think is the new lipo packs I soldered up today, using maxamps 4000 cells. I have a 4s 12000mah setup in it and it's incredible.

Pulling wheelies is getting +100A spikes and the voltage (fresh off the charger) was holding over 3.7v per cell. Lowest voltage recorded in the two minutes zipping around was 14.9v on a 107amp spike.

I think I will try making my 6000 packs into some 9000s and I may have to retract somewhat what I have said about lipo packs. eg lower rated cells are fine if you run a large pack... that you don't need to buy the latest and greatest 20C cells etc.

This is still true, imho.... however after seeing the punch this huge pack delivers I wonder if the TRUE 15-20c cells could have a bigger performance edge that I thought over the good value 10C type cells, if the size of the packs are similar.

Some aspects like top speed I doubt are affected much, but holeshot is very impressive with the near-zero voltage drop.

Anyway I will run this thing tomorrow and see what it can do.
