    Question Open Wheel v.s. Closed Wheel Bodies?

    Hi guys,

    I am looking at either a Proline Monster Fusion Body or a JConcepts BAJR Body trimmed like The WAR BAJR II. Which one would be better for bashing? (jumps, rollovers, etc.). Would the type of body affect durability? Also would they jump different?

    For jumps, I would say open wheel is better, since there is less are drag. Also, since the open wheel bodies are smaller, they have better structural integrity, so they will be more durable.

    Closed wheel bodies are definitely better for durability, since the tires and suspension components are protected from impacts a bit better. Most SC style bodies won't jump as well because air gets caught under them, but the Proline body has vents, so I doubt it would be a big difference.

    Edit: Didn't see the other post.

    I guess open wheel bodies would be better for the body's durability, but not the suspension.

    Ok. if I were to have bigger tires, would the suspension get hurt more with an open wheel body vs a closed wheel body in rollovers

    Not really. Most of the time your suspension gets damaged it is from hitting something head on.

    I would say open-wheeled and close-wheeled are both equally durable in both rollovers and direct impacts. In most cases, body types don't make much of a difference. At high speeds, the suspension arms will break regardless of what body it has due to more kinetic energy, and the closed-wheel body would also get damaged if it had one. At low speeds, the suspension arms are strong enough, so having the body isn't much of an added protection. However, having a closed-wheel body would provide more protection for the servo since the wheels are partially shielded by the body.

    About the tires, having larger tires add more mass, so it provides more inertial energy during impact, but unless the tires are huge, it shouldn't make too much of a difference.

    I feel that a closed wheel body is better for being able to roll back on its tires after tipping over since it's kind of like a dome. This is just from my personal experience. Not sure if this is actually the case.

    Depends on the body, really. THe BJAR body has that high scoop feature on it that helps keep the truck from turtling.

    Maybe you should just choose the one you like the look of more if you can't decide.

    I have been running open wheeled for quite awhile. I went open wheel to protect the much weaker body from damage.

    Open wheel! The BAJR body is my go to basher. I got the idea from Dr. Isotope himself back when Ultimate RC was still around. This is my favorite basher truck. So much fun!

    I've got a question. Would hitting the curb at a slight angle or skidding out into a curb break the car on an open wheel body?

    For the car, I'm thinking a car like squeegies WarBAJRII body with 2.8's

    With any car, if you hit something expect it to break...consider it lucky if it didn’t.

    but like with a closed wheel body it will just bounce off. Will it do this with an open wheel body?

    As has been said, expect physics to win out; collisions at speed impart a lot of kinetic energy. I have a closed-wheel body and I snapped an a-arm in a collision because the thing I hit did not contact the front bumper. The biggest difference I'd say is how wide your bumpers are. Those are basically springs to dissipate impact forces.
    Watch F1, Indy, NASCAR, or trophy trucks - big bang ups tear apart the vehicles.

    A strong Lexan body will not protect the wheels from damage if the impact is enough to break an A-arm. The body will also be damaged. With open wheel you are less likely to damage the body and only need to replace parts of lesser value.

    I have not seen a body that would be stiff enough or tough enough to take a hit without flexing. They flex enough so that they do very very little to reduce the impact taken on the wheels in a sideways hit. I donít think the body style will make any difference in the durability of the car. The place a closed wheel body helps is if you are racing and get against another car, the body will keep the car tires from contacting so you are more likely to come out of it with just a nudge. With open wheels the tireís climb on top of each other and you can get some pretty good air time.
