|  Tubers & Roll-Overs
I've just built my first tuber rig, and absolutely love it... I always hated hacking my pretty new painted bodies up for tire clearance and I just love the look and compactness of a well built tuber... After spending a week or two driving the thing, I'm having an issue, and I'm wondering how the rest of you that build and drive tubers deal with it it... With my bodied rigs, If I'd roll, it was usually a 50/50 shot that I would get back on my wheels again... But with my tuber, it seems like I am lucky if I make it back to my wheels 20% of the time... Anyone else experience this? anything in the tuber design that might help with this? Discuss... |

It's all in the design. If you have a raised cab and narrow roof your percentage will go up.

I try to remedy this by creating slight curves or having the top to be at a Point, to where it would either teater towards the front or the back. Having the angles point towards the tires if possible. I also try to keep the roof area as narrow and low as possible. But in the end I'm working with what the customer wants it to look like. But I think in general a tuber is going to have less of a chance at recovery. |

That can be one problem with the tubers,Ive thought about putting a bar on top that kinda sticks up to help roll overs but never have,i just deal with it.

Yeah you should see mine, I have no chance of rolling it back over. When it rolls it rolls right over on the roof and sits there wigging with all 4 tires off the ground. I'm redesigning it this year just for that very reason. I've played out some ideas and the best idea to me seems to be tall narrow roof as then it will only flop.

This isn't really feasible for a 2.2 on 5 inch tires, but for sure my super will be designed this way... | |

The key is to make the front tires tought the ground instead of the whole chassis making all 4 tires rest in the air. By raising hte roof in the back and having a shorter front you can make a chassis that will come to rest with the front tires touching the ground. Then you have a chance at flipping it back over.

The first tuber i built would almost always flop over on it's side but I could never get it back over on the wheels. The one I just built Tuesday has a TALL roof and it shouldn't be a problem once I get it done.

So what is the consensus opinion here on the best way to build a chassis to roll back? Tall roof front tires closer to ground on rollover. Truck should have the tendency to flop rather then roof roll. Low roof tires in general closer to the ground. Should have a greater tendency to roll over on the roof when it goes over. |

I think a taller roof thats round would help. But I really think it's more then just that. I think it's mostly technique. As you see the front tires pulling of the rock and now they won't come back down. Nail the throttle till your back on all 4 and quickly let of the throttle to stop. As long as you can get the front tires to hit the ground during a roll over you have a chance. Once those front tires hit the ground you want has much wheel speed (Throttle Forward) to keep your momentum.

my Gopher tube chassis does the same thing. But I have found some cool logs that if I hammer the throttle it will do a backflip. In mid air!
