I would have put this in Electric, but it's not hobby quality.
I got bored and saw it was snowing. So I went into my room and unfortunately only had a havoc heli to play with...woohoo, thats real fun in the snow! But then I opened my desk drawer and remebered my ZipZaps. I pulled it out, threw in some hald dead batts and went at it. The 4wd and no diffs make them capable if you have the extra motor, you pretty much need it. I run the high speed motor on stock gears for extra torque, and when you have good batts it really works well. But if you have dead ones, your SOL.
Anyway, got pics and a vid.
Sorry for low quality, I can't shoot vids very well...my camera is too sensitive.
