Scratch built rc excavator

[ashrock1990]

hi its awesome project im making same project for my engineering..can u tell how did u made hydraulic pump...its also the problem im encountering..thnks

[59aiden]

I searched up ho scale exevators but youtube got this?

[GEXRGuru]

very good. they could use small lightweight equipment like that on mars

[ratdoghippy]

OMG tonka neds to market that!

If i had this when I was a kid it would have made cleanign up the dog crap in the yard so much easier!

[crazygood150]

that is honestly the coolest rc toy ever, I really want one now!

[TDi01]

Did you build or buy the slew ring gear. how does it work on your machine?

Are the Garden trucking spool valve blocks big enough to drive cyllinders that are 20mm in diameter? nice machine....

[sweetbob67]

nice i honestly don't have the pacients to bouild that from complete scratch without instrucions a kit or a proffesional

[chappy39]

Throw away the Wii man and lets play with some real toys!

[22fatcat]

thanks man I know I should do somthing about the sound

[500passwords]

killer job buddy , you just need a song playing and cut out that noise. although i should shut up , your videos got about 20,000 more views than my videos combined and im building a real one. once again great job

[rocksaustin]

Why is it so loud!!!

[22fatcat]

It is loud because of the coarse pitch of the gears that I used when I made the pump. I might make a new pump using different gears smaller in diameter and a finer pitch and hopefully that will not be as loud

[CrazyMxRider123]

is it hydraulic?

[nuclearthreat545]

Nice, this cool. Good job building it

[VerticalAddiction]

Fantastic ... coolest scratch-build I think I've ever seen - any other builds on the go? I have sratch-built a robotic bio-mechanical hand/forearm which responded to input from a data-glove using 2 micro-controllers - I'de really like to learn more about small-scale hydraulics, can you lend and hints or point me to any resources? Your video was a clear demonstration of what's possible ... just awesome

[cowling4]

were can i get micro hydraulic system from?

[MGAPUTANGINA]

how many gear or rather pumps did you use? anyway, nice video.

[22fatcat]

I made one gear pump I to run the hydraulics

the tracks and house are gear driven

[7501234]

were do you buy hydraulic parts from

[Scanianisse]

How did you join the parts together, did you weld or did you buy pre-assembled parts?

[22fatcat]

All of the body parts, arm & bucket are made of 20 gage sheet metal I used a cnc waterjet to cut the the parts out then I tig welded them together

[trentskeze]

can you make me one id be wiling to pay

[obxnitro]

i want one for my cats litter box

[woofybigj]

I like it good job, you should be building these for collectors.

[Butterz771]

its abit loud

[napabryan272]

where did you find the hydrolic parts?

[22fatcat]

i made the pump the cylinders are from mcmaster carr the spool valve came from garden trucking.com

[technoman43]

nice

[hammerdwn20]

nice job. thats one fast excavator
