Ill have some video soon. All i really have to say about building this is get the model you want to build, then take measurements of the what your going to build. Then get batteries, motors and esc's and receiver that will fit. This 1/50 scale is a little bit on the small size.

My video just click the picture.

[doodlebug]

Wow! will be following this micro project.
Cheer's, Neil.

[1/50diecast]

Well unfortunately the 2 servos i salvaged from an old rc sabre helicopter that crashed and burned, wasn't compatible with the GWS 4 channel receiver. Other i get some GWS servos and lift the rock ripper and lift the front blade. I was also thinking of getting firgelli actuators and be able to have a tilt on the front blade, but i wouldn't have a ripper control.
I got to say this dozer has some push!!!
Click the picture it a video.http://i1086.photobucket.com/albums/j459/nowherethere/Mobile%20Uploads/th_VID_20140613_170540_960.jpg (http://i1086.photobucket.com/albums/j459/nowherethere/Mobile%20Uploads/VID_20140613_170540_960.mp4)

[1/50diecast]

I also need to make a skid plate chassis so the guts dont spill out, it was necessary to cut the bottom out to make some room for the battery and esc and the receiver.

[doodlebug]

Cool!
Cheers, Neil.

[avel]

That's really cool! Makes me want to try and convert a 1/50 diecast construction model so I can run it on my O scale 1:48 shelf layout.

[1/50diecast]

Yeah, i plan on converting a dumptruck and a loader at some point. Its just a little expensive to do this, so far this dozer has cost me $320 but im happy with it so far!

[1/50diecast]

It was tricky but managed to cram everything into the dozer, now i just have to mount the blade to the servos and i should be done!http://i1086.photobucket.com/albums/j459/nowherethere/Mobile%20Uploads/IMG_20140615_181619_661.jpg (http://s1086.photobucket.com/user/nowherethere/media/Mobile%20Uploads/IMG_20140615_181619_661.jpg.html)

[1/50diecast]

Well dirt does clog the links, i think ill try running it in potting soil. Got the blade working. Now i just need to make linkage to the ripper. Then some touch up and it will be done.

pretty sweet ride very tedious wrk

[1/50diecast]

Yes it is, the hardest think is cramming all the electronics in the dozer.
Thanks for all the complements guys :)

[1/50diecast]

Well im not digging the servos lifting the blade, i have to hold the channel to keep the blade up or down. So i am thinking of a new approach ill lift the blade with a motor with a screw and nut and another esc.http://i1086.photobucket.com/albums/j459/nowherethere/Mobile%20Uploads/IMG_20140618_200315_676.jpg (http://s1086.photobucket.com/user/nowherethere/media/Mobile%20Uploads/IMG_20140618_200315_676.jpg.html)

[1/50diecast]

Ok spent the day looking for micro linear ball drive motors, but they only sell to manufacturing companies, so im out of luck. Time to build my own!

[1/50diecast]

My thoughts are to use a micro motor for micro helicopters tails motors... connect it to a vary small bold the size as the motor shaft and couple it and then couple the bolt with another shaft in a shaft that covers the motor that looks like a hydraulic piston.

[1/50diecast]

Its going to get interesting

[doodlebug]

Have you considered converting a servo to 360' full rotation, then the esc is built in.

Cheers, Neil.

[1/50diecast]

That is awsome! I might end up using that technique to lift a bed of a 1/50 dump truck, when i get around to it.

I did find a gearmotor that is 6mm in dia. and a 7mm tube that the gearmotor will slide into the tube. Then using another 6mm tube that will slide in the 7mm tube that will be attached to a nut thats driven by a screw. All i am doing is waiting for the stuff in the mail.

[1/50diecast]

Here is the motor that will drive my actuator, just waiting on the tubes to put it in.http://i1086.photobucket.com/albums/j459/nowherethere/Mobile%20Uploads/IMG_20140626_165241_958.jpg (http://s1086.photobucket.com/user/nowherethere/media/Mobile%20Uploads/IMG_20140626_165241_958.jpg.html)

[1/50diecast]

Needs paint, but this dozer is to small for real hydraulics so here the next best way for a realistic look.http://i1086.photobucket.com/albums/j459/nowherethere/Mobile%20Uploads/IMG_20140709_201404_227.jpg (http://s1086.photobucket.com/user/nowherethere/media/Mobile%20Uploads/IMG_20140709_201404_227.jpg.html)

[1/50diecast]

If this is strong enough ill try making a front loader this way.

[1/50diecast]

Ok round two! So had to put off my project for a few years, ok more than a few years. Hey im back at it now. Cool thing is that over time rc equipment and such have gotten smaller! Ive upgraded from a 4 channel to a 6 channel receiver, smaller battery and such plus more. Im still a bit busy in life but im going to start putting in some time and finally finish this little do-da! Really lately been brain storming on how to finish the dozer.

[1/50diecast]

Alright got the screw drive actuators glued together... Got to do some touch ups to make it look cleaner.

That is awesome!!! Glad to see you're back at it.

I've been wanting to build something tiny also, i know DasMikro has an 8ch and escs much cheaper than the german ones

Awesome website, ive been checking out a lot of sites like this one. I do have a HO train set im planning on seting up on day. Ive had it sence i was a small boy. I do want to RC most of it, plus there has been a lot of technology that has came out... Especially because of drones craze

This is an awesome project, it's nice to see you're back to work on it once again!

[1/50diecast]

Ok got some work done, there is some more work to be details to do and a lot of wiring.

Got the ripper servo hooked up.

Here i added some brass tubes to slide the tracks to put tension on the tracks.

Thank you skeeter.

[1/50diecast]

Got the electronics in the best fitting spots that i can think of, I have to shorten and solder some of the wires next.

[frizzen]

Looking at your electronics, the machine is actually bigger than i was thinking. I thought you were goint to have to use the tiny linear servos in it

Before you start soldering it together, i'd probably drop most of the wires to a smaller gauge. Plus you could color code stuff better

I was think of going to a small gauge wire, but like you said the model is big enough. I managed to get the wiring i have without having alot of resistance from smaller wire.
