[td9clyde]

yep the machines you build are awsome i wouldn't have thought of useing servos for drives or putting in the twin gear drive box very nice work

Thank You very much. I tested, repaired & installed automated vehicles for many years. So, it gave me a good feel for hydraulics, screw drives & servo motors.

You are welcome.

Since I had to order more parts, I have a more accurate list:

Radio system
Tamiya twin motor gearbox
shims for tamiya gearbox assembly (you loose about 10 to 20% of gear contact on some of them if you leave them sloppy)
silicone to seal gearbox up (makes it last a very long time)
2 x slotcar motors (tamiya motors are 3.5 volts and fry quickly)
Aluminum stock to make drive hubs
4-40 screws & washers to secure gearbox to chassis
Saber tooth motor controller
5 volt 5 amp (continuous) bec
Hitec Digital HS-7955 TG lift servo
2 x hitec hs-5065mg digital servos for bucket curl
Hitec servo programmer
3" Y harness to join the 2 bucket curl servos
2 x 12" male servo leads to extend the bucket curl servos
heat shrink for all of the bucket curl servo wiring
piece of bicycle inner tube for lift lever cover (need to post pics)
4-40 rod and clevis for lift lever
lead weight
and 1 boat load of patience

Hi,

How do you use the channels on the radio?

Somthing like my drawing?

The bottom drawing is how I like to operate but, I steer with my right.


I decided I should keep the prototype Loader for myself and run the heck out of it to make sure everything holds up nice. After running it for a couple of hours moving dirt I noticed that the motors where getting really hot because of the 205:1 transmission that I was using. If you listen to motors in the video they are screaming at anything over half throttle. So, I put the heavier duty tamiya tranny in it (the gears are twice as thick) and now the drive ratio is 115:1 and now the motors never go over 130 degrees even after 1 hour of constant work. It still has power to spare and it sounds much better without the motors screaming.

I was asked to make a video with it running slower. I didn't realize that a Cat 297C has a top speed of only 8.5 mph.

Nifty drawing, I saved it to modify later in "paint" for future explanations of how set up radios.

The bottom drawing is how our cat skidsteers at work operate.

[ihbuilder]

yes the bottom is cat joystick setup boom bucket on the right and on the left stick for skid - fwd/rev left/right on ex - crowd and swing . what's neat about what cat did with the skid steer controls , is they match the excavator controls . just instead of swing your steering and instead of crowd in / out your traveling

I'll have to switch my crane & skid steer to the Cat setup then.

The full scale equipment operators that have run my crane & skid steer have said that its backwards to what they are used to.

Hmm , then I guess I didn't get to run them yet . That would've been a sight

I thought you ran my Dragline Crane?

The rubber tracked loader has 20 hours of run time on it now and everything held up great. Even the tracks are still fine. So, I feel completely comfortable selling these. Albert (Aseejr) is my first customer and I have his loader over halfway complete.

I made a quick video moving some timber around so, now Albert can help move logs around the next time he visits Lou (trancksntreadslou) and Greg (RCLogger).

Nice Scott. Now for more attachments huh? A log grapple broom or Fecon head? hmmmm

Just watched the video. love the Quick change and the loader seems to have lots of power. I can't wait to see Alberts when it arrives.

Thanks Ben. Bruder sells the bucket by itself for less than $3. it would be fun to buy a couple to mess with and make some other attachments out of it.

[aseejr]

Sold again. Impressive.

[td9clyde]

a 4 in 1 bucket would be cool but kinda hard then you could bit stuff to pick it up or you could use it to gradeout the sand or rubber chips

That would be cool but, I think it would be very bulky to add another servo to move it.

Well, the first production unit is finished (Aseejr's Loader:-)

Here is a video of it to show the finished product and how the radio is set up. The steer & drive are on the right, lift & curl on the left. If your radio has a spring loaded center on the throttle you could run the tracks with the left stick. But, without a spring loaded center it would probably be hard to find the center/neutral to stop the loader from creeping when you want to stop moving.

I am starting on Doug's (Firefighter30) next

[9W Monighan]

I love it!
But I can't here anything, I don't have speakers here at work. My new monitor didn't have them built in .

Scott

You are amazing at building these conversions it so great watching you convert these you have some dang good skills..

[woodhog]

loader looks great .what will conversion price be?
