Hi together!
This week I took some pictures outdoor...







@gauthib12: dimensions will follow...I´ll have to check them in the workshop.

Wow this is just amazing. It looks fab. How much did it cost you to build in total If you don't mind me asking?

[Grainfarmer]

Here you find the chassis-kit:

...+ 4 speedcontrollers (about 30 Eeros each), + 3 servoes for steering and 3pt. hitch...

Frank is this one up and running yet? Need a video!

Hi together!

Got some new stuff: B-Trim module, released this month...

http://mfz-blocher.de/fahrtenregler.html

With this you have a "cruise control" and reverse gear shifting just with one touch of the stick. May be interesting for bulldozers, too...Here´s a video how it works:

[Acadieman]

That's pretty neat.

[Grainfarmer]

Thanks!

Here´s another video from a test run with a subsoiler....onbordcamera...:

The tractor does really well on that ground, I was surprised. Is it hard packed ground? I also love that camera angle, nice touch!

[Grainfarmer]

The surface was relatively soft, but deeper it was hard packed. I just brought the subsoiler 1/2 inch deep in the ground.....normally it would till 1 inch deep.

Frank,you making it look so easy.

[Stuart]

Nice one Frank! Seems to work really well.

Do you know what motors and planetarys are fitted to your Claas? They look like Robbe ones but was wondering what spec?
Also what speed controllers did you use?

Cheers
Stu

[Stuart]

Sweet! what do they weigh?

[Grainfarmer]

Found some more pictures of the model...:

[Claus]

Oh, c'mon Frank, now your teasing us with the Challenger. Tell us more about it!

[Claus]

BTW, love the Trelleborg tires on the Challenger!

[Grainfarmer]

Maybe the Challenger will be converted one day, but I got too many other projects in the workshop. Untill then he will stay in the display case.

How much torque those motors have? I need to choose motors and I have no idea how much torque is needed for RC tractor.

[Grainfarmer]

I do not know how much torque the motors make. In the CLAAS tere are 4 brushless with a planetary gear reduction.
In my MF 1155 I have two of them 12V RB-Motors: http://mfz-blocher.de/getriebemotoren.html
Strong enough for plowing...
