Re: pic: Small?
It may be just the angle, but it looks like the inner toughbox sprocket (to the chain to drive the front and back wheels) has very little chain wrap. No matter how well you tension it, you usually want at least 120 degrees of wrap on any powered sprockets like that.

Looks good though! Can't wait to see it with a kicker.

ya we know, it's got like 4 teeth of wrap, which is why we added the tensioner. it should be fine, but if it isent we will just move the tensioner and add some links to the chain.

Well either way I really think that your guy's robot will do amazing in competition. But I have another question.... Are you guys going to hang of the tower at the end of the match?
