Well done! And thanks for listing the parts used. Helps for those of us not experienced with RC components.

Thanks Joe!

I charged a 7.2v (6 cell nimh) 1500mah losi mini-t battery and ran it for over an hour today to see how much power it uses and it was still going strong. So, I don't really know how long one charge will last but I would say it is efficient.

Great build! Thanks for showing what motors you used with the Tamiya gearbox. I've been stuck on my Bruder conversion looking for replacements for the stock Tamiya ones. Looked at everything except slotcars - DOH!

Nice build Scott! You should have built two or three in the process so you can keep one. You still should let Scotty up here try to break it

Thanks Steve! I am in the process of building 2 more right now that are already sold and I might just keep the first one I built for myself. York should be a blast, I can't wait.

Well done...I admire you guys that can make models that small work... Any thing smaller than about 1/8 scale is too small for me...

Thank you very much. I really enjoy the engineering challenge of getting strength & power out of these little machines.

I improved the bucket curl mounts. The mounts on the prototype loader work fine but, they don't like nice.

This design has more rigidity and protects the servos from getting hit:





With the servo screw heads milled down it allows the two servos (sitting back to back) to fit nicely in the lift assembly and creates a rigid assembly.





I also made beefier aluminum drive hubs. I'll post up pics later when I get the 4-40 screws that I ordered for them.

Thanks Ed! Yes, it loads the Tonka fast. It'll probably load the Mack DT fast too but, I'll need like a 2" or so tall ramp to load it.

Another photo of the new bucket curl mounts. If you look closely you will see a small kick plate between the servo and the hoop mount. It locks the bottom of the servos tight against the bottom plate.

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
