Compact gear shift (2 speed)

[RoscoPC]

For my latest MOC I've designed this compact gear shift close to the differential: the lower axel can be moved through the old technic flex cables directly from the cockpit, and the axial joint connect it to the crankshaft.

It's a pity that I had to remove this feature when I've installed an XL motor to make the car RC, since the torque is too high for the thin gear and its weak connection with the axle, and it cannot guarantee a proper connection with the differential gear (while for a static model it works smoothly)

Enjoy.

Nice. Have you tried using double bevel gears instead of simple bevel gears? Those are a lot stronger.

You are completely right: but I haven't space enough to convert the same concept with double bevel. In fact the final solution is this one, with double bevel gear but just one speed and... neutral (I kept the lever actuated from the cockpit)
