Bruder Cat Dozer

[Robert Davies]

Last few years my niece has had her birthday at diggerland so guess who had more fun

OMG - I just google'd Diggerland! That looks like way too much fun to be wasted on children!

Ahem! Nice Bruder conversion btw Ian.

i was also in the HE services dancing digger display team we would go to the bath and west show Newbury show ground and many country fairs and i was always the last jcb 3cx to go right up in the air so our boss would drive under us all in his white jcb which he drove from john o groats to lands end and this thing did 65mph so big boys toys are a hit with me im thinking of making Rubens cat d11 into rc so might be calling on you for some help as always ian but cracking job on your blade

Hi Paul, I had a play last night with the mixer and got it to work. Right stick channels 1&2 so deleted the mix off channel 2 and copied channel 1 mix to channel 2 and reversed it so that gives forward and back wards on channel 1&2. Then I tried same for steering and couldn't get anything to work then after an hour realised I was telling the radio to do it on str command which is on left stick changed to tur command and now turns on right stick.

When I get the wiring an battery securely in place a do a quick video as works really well.

Cheers, rear drag arm next, although tight for space.

quick video



Battery is loose underneath causing it not to drive far away.

I've ordered a 6v lead acid battery for a bit more power to the servo's and hopefully add weight to the tank so help traction.

Okay guys,

Now onto the drag claw

Cut off the old rod/arms



Cut off this ring, think it is a finger pull for the toy



Used some carbon fibre fishing rod to make longer arms



Next the shape of the claw frame stopped it from going past 90 degrees,



So filed the square edge to round



Next added some weight to the claw



Onto the mechanics, couldn’t get a servo push rod to work because of the drive servos been in the way. So gone for a pulley arrangement where the servo pulls a flexable cable to raise claw, then it falls under it’s own weight.



Quick video



Then some cutting to hide the servo which is now in the drivers cab



And interior back in place
