How much do the transmissions weight... just a suggestion... make sure the robot weight is balanced... our 2003 robot was back heavy since the transmission was in the back like your design... but i think we only flipped once... the overall design looks great... the frame looks strong... you might have to change your transmission depending on what motors they give us this coming season... good luck...
p.s. Never mind my changing tranny comment... i think you just click submit just a second before i did...
