Quark fried, blown capacitor...

[zeropointbug]

For me personally, I don't care for more runtime than 15-20 mins (18/51, 7XL), but the weight isn't heavy, it's just not as dense as LiPo (they sacrifice safety for energy). Another thing about the A123's is that they deliver more of their Ah rating compared to LiPo.

I will for sure let you know how my system compares to before with more caps on the Quark.

BTW, I used to have 1/8 Moabs on my 1/6 rally car (4wd). They were good all-around tires, on asphalt, dirt, and grass (drifting was super fun on grass)
