Differential for SIKU RC (UPDATE)

Well, this is actually not my scale as I only operate in 1/16

( ***http://youtube.com/user/akolpen?feature=results_main">http://www.youtube.com/user/akolpen?feature=results_main )

A friend of mine do collect the smaller size though.

I wanted to do something to these 1/32 scale tractors to steer better.
I already modified the servos to rotate more, giving a tighter turning radius.

Still not enough. A differential is definetly necsessary for a perfect turning.
The problem is that you need a heavy rearend to avoid wheelslip, making it turn really bad, as the locked axle forces the tractor to go straight.
Till now the only you could do is add weight in the front to be able to steer. Now I hope to add weight both in the front but also in the rear.

Still haven't tested it yet, but pictures is here....:

That depends on the wheelweight. If you put enough weight, so the wheels can dig in to the soil, you won't need a lockable diff.

Hello,

thank you for your interest.

White plastic housing connects to the two brass ends (3 pieces glued together), making a complete axlehousing. Inside the two axles rotate freely.

So you are somehow correct in your thought;)

Thank you!

First test today on a FENDT tractor.

Turning radius is reduced from 64,5cm to 54,7cm (measured inside). That's minus 15%.

The tractor is equipped with the standard servo and no modifications is made to it. I will test the diff. on a John Deere later, with maximum steereangle.

More to come....;)

Hi Yannik

A full description on how to modify your servo to travel more is on the way. Just need all the photos from my friends camera.

Thanks

Anders

The Differential can be seen at Traktorado 20/10-2013.

I will be driving my John Deere 1:16 tractors at the RC area, but I will also bring the 1:32 tractor with digital steering servo and reardifferential.
