I see what you mean about "SPACE".
Cheer's, Neil.

Thanks for the link!!...yes a diff. would be much better!!! but space is a problem even on this bigger model...the axle housing (pipe) is about 2.850" OD

Here is a vid of the steering...it is a bit slow but it does seem to have enough torque ( about 4 seconds , full travel, left to right)

Thanks for looking....

Sweet! Now lets see it driving around!
A friend of mine is running a brand new PC5500 face shovel in a BC coal mine. Yesterday he dropped by for a Xmas visit with a present for me...A 400 page operation and maintenance manual for the machine... In 1/10 it will be 35" tall at the house, and about 29" wide with the standard tracks. I'm not sure if I will try to build it but if I did it would be huge.

Hi, thats a fine steering setup you've got there) The speed seams more than fast enough i would say. Is that just a standard servo? It seams to follow the stick, is it some special programing that makes the servo travel that many turns in each direction, is it available on several kinds of radios? what about the pot.meter that usually is in the servos, is it removed or?
I've got a Airtronics Sd-10G here, that I really haven't started to get that familiar to yet, but I noticed something in the book about adjusting servos up to 150% travel. On your, you must have but it to several 1000% travel?

Here is a link to the winch servo I'm trying in steering, it has 3.5 turns

I got the steering idea from looking at this set up at Servo City

Thanks...( I didn't get a video when I was trying it out the other day, the steering set up does have enough power even with 60lbs of weight in the box, but this is on a flat concrete floor...dirt could be a different story.I just have foam in the rear tires and the 60lbs was really flattening them out but it still seemed to turn OK , but I think the rear tires might be slipping on the rims)

A PC5500 in 1/10 would be awesome!!! If you build it you almost won't need your mini ex. anymore. What about the PC3000, just a bit smaller

I think a 1/10th 5500 would be a little hard to move around but you are right, I could probably sell my Kubota!lol I have been planning a big Euc R18 in my head for a while so the shovel may come in handy some day...

Instead of running foams in the rear tires, couldn't you just put the valve stems in the center between the duals?

Ya a 1/10 shovel that size would be a challenge to move around sounds like work....you would just have to build a bigger truck to haul it around, something like the photo but bigger...much bigger

I plan on using air on the inside duals and have the stems facing in toward the frame, I really don't want to see valve stems but I can't help it....there is no room between the tires to get at the valve stems, and they are a split rim (two halves) so that means the tires must be mounted in order to put air in them.....may need a way to connect the rims together before they get installed....
