Attitude correction in the Air (car) Belt/Shaft drive
Hi
I am just doing the reading to buy a 4WD buggy. Great reviews here. I want to understand more about the differences in driving between Belt and Shaft drives. I know jump shape, speed, springs, balance /wt distribution all have an effect on the way yhe buggy launches of a jump. How to control attitude when in the air off a jump? When in the air what is the difference in control between a Belt or shaft drive car? Thanks for any response. Jeff |

Hi.
Both types of drivetrain react the same. If your car is nose down, throttle up to level it out. If your car is nose up, brake to level it out. Always try to accelerate up to a jump, it's easier to bring the nose down than bring it up, you have gravity on your side.. On big jumps, try real small blips of the throttle in the air to keep the car level.

to add to what Adam said
you can slightly level the car out with the steering also turn to the left while throttle is on it will lean that way and vice versa

Shaft and Belt drive cars react different when the throttle is put on. A shaft drive car has drive instantly where a belt drive will take time to put the power down ( belts stretching). Also with the position of the motor efects the car on initial throttle input, on the shaft drive motor from back to front the car can vear from left to right efects of the motor spinning that way. where the belt drive car motor going across the shift is from front to back.
Thats how I thing it works anyway. |

Thanks for the quick replies.
So the torque effect of the wheels and axles speeding up or down (their MOI) effects the nose up or down. I thought the torque of changing the motor armature speed might have had a big effect. More so on the shaft drive although a bit cancelled by the long drive shaft turning in the opposite direction. I thought it might have rolled the car sideways. Jeff |

It does on the shaft drive cars with the cells down one side like the Lazer, there was certainly a knack to controlling the origonal BJ4 in the air. When you have the cells in saddle formation the extra inertia in roll dulls the effect down so far as it's insignificant.
