Which Chassis has the Lowest Static Torque Twist? TRX-4, MST, or Absima?

Torque twist can make the body and chassis tilt to the left or right side. While dynamic torque twist arises only during short phases of accelerations, static torque twist occurs during slow movements, for example when the motor pushes the car against static obstacles or steep slopes. This video explains how static torque twist is generated and compares three different chassis models with respect to their stiffness properties that can be related to static torque twist.
The three RC chassis models are:

Nice work! Neat to see this type of experiment and calculation.

[@rcscientific6004]

Thanks for your appreciation!

You need to raise the upper links position higher at the axle mount. Raise the upper links 5mm to 8mm with a custom mount & your torque flex will be nearly be 95% all gone. Only going up straight vertical inclines will cause any torque flex that is left that you will not be able to get ride of because every single crawler vehicle has some level of torque flex in all honesty.

Awesome video, but the links in the description are uber-borked ;)

[@rcscientific6004]

Oh thanks so much. Now the KZbin links are fixed!

Me gusta mucho el video, te recomiendo que pongas subitiulos en español. De verdad sirve mucho. Saludos desde Ecuador.

Amazing!!!

Hello, A nice video and very interesting!👍

[@vdel9036]

Suspension stiffness doesn't matter ? 😳🤔

[@rcscientific6004]

Suspension stiffness/compliance generates an additional angular deviation, which adds to the one generated by the chassis stiffness shown in this video.

[@MrFroggy29]

hello Why 1kg for Absima and 500 grammes for the other?

[@rcscientific6004]

Because the Absima chassis was much stiffer. Actually the weight does not matter to calculate the stiffness in this „mathematically linear“ approach.
