hootie, when I'm running a 6 cell NiMH by itself, it sags right at first before accelerating rapidly. When I run two 6 cells in parallel, it wheelies like nobody's business. I'm thinking your battery might not be providing the current demanded. Just a thought anyway.

In related news, I was able to temporarily fix my broken a-arm by creating a "cast" around the breaks using super-glue and strips of paper towel. It works surprisingly well. Good times!

thanks bro!!! i'm actually just running it with the stock battery....and just 1 2s 20C 800mah flightmax lipo (it supposed to be used in my srb quark but i couldn't resist!)...i'm guessing once my 2s 1600mah 20C zippy get here i'll be a wheelie machine .. :)
