Thanks for the comments guys, well since its my first animation, i did a 30 frame animation and wanted to squeeze as much as i could. Also yeah the animation has a sort of "stop" like nordic noticed
its just that c4d has an animation curve which slowly increase and decrease the speed according to the timeline, you can notice this on the rear wheel.
Redz its true, simple animation brings a lot of life to a chop. Also im using Cinema4D and Octane. it took 1 minute per frame to render with octane
