    Wrong forum? Eurobricks here, not gtaforums

    Sure use it! Its quite powerfull, yes and you may need to fiddle arround the hit te perfect link lengths, but once all is alligned it works flawless. So again USE MY IDEAS, and i mean everyone, thats why i share them and the LDD models!

    Here's my new rather simple MOC. Because doing a simple dump truck is well....simple, I decided to spice things up by adding suspension and using only 2 motors to do 3 functions. So how can you use 2 motors for three functions? The answer is rather simple. I used a differential connected to steering system. As soon as the steering rack reaches its maximum position, the power is diverted to the LA, which lifts the bed. In order to make sure that the steering will always work before the LA i Used some friction pins parallel to the LA functions, to make sure the differential will always steer first. The brown gears are from the drive motor. The red ones are froms teering motor. The green diff splits the power where it is needed. After building this central gear system, there was another problem to solve. The LA is stuated in such manner, simply pushing agaisnt the bed would be very inefficient when trying to lift heavy loads. After some trial and error i came up with this special linkage, which follows the circular path of the bed, therebye helping it lift, instead of just pushing against it. The LA in green pushes the brown link, which in turns lifts the bed. The small blue and yellow links are used to make the brown link follow a certain path in which it not only pushes, but also lifts the bed, therebye creating more force. After adding a tiltable cab, battery box and suspension the truck was done: I used independent suspension for first and rear axle, whilethe second driveaxle uses double tyres and live axle suspension. The second axle is also configured in such way to carry most of the rear weight. The cab can be lifted to reveal the receiver. And a short video of the truck in action: http://www.youtube.com/watch?v=R9wvAlX7Z-U All in all its a nifty little truck and very fun to drive arround and dump stuff out, especially bricks. Also by just using 2 motors and only one IR channel, this allows for more RC models to be driven at once like on exhibitions, etc,... I also made the model in LDD if anyone is interested: http://www.brickshel...ruck/dumper.lxf P.s. MOD its dump truck, not Sump truck, please correct the topic name.

    Really great! Its so small, yet functional!

    Seems somone made a mistatke when mounting LA's.... I am 100% sure that the half beams with half a stud offset have to be inline with LA's. In other case that would just create too much sideways strain for LA's and unused travel as seen.

    Not if they would use a 6 way splitbox
  7. Zerobricks
    So if slew is not manual, than we have next functions: Raise Extend Whinch Outrigers- splits to extend and lower They could use a 6 way gearbox and had functions like: Raise Extend Whinch Rotate 1 turntable output outrigger extend second turnatble output outrigger lower Would work nicely.... This seems lazy, especially having to split one function (outeiggers) two times!

    Where's the mysterious speed racer or something set? EDIT: Action Race car

    Please argue in other topics, as in offical 8110 one or via PM.

    The tow truck uses 2 small cylinders, one to tilt the ttow thing and the other one to extends it. Anyone notice the red gears where the crane's outrigger axles slide? They seem to be the new 8 tooth gears? Dont they have friction?
  11. Zerobricks
    Wasnt there same situation last year with 2 topics? Mod, merge them please.
  12. Zerobricks
    The old crankshaft oval piece seems to be back where the LA's meet the boom.
  13. Zerobricks
    Nope, just looks so. A gearbox for controlling the extension or lift of stabilizers or rotation of superstructure?
  14. Zerobricks
    Just as I said, the gearbox is indeed in the upper structure! I bet there is some new gear which allows slidinga xles for MLA's.
  15. Zerobricks
    Or use the CV joints, if there isnt too much torque involved, like steering etc..
  16. Zerobricks
    The fact the outer part slides, is because the inner part houses an old style diff with clutch changeover parts, which allow a 32 axle to slide smoothly inside. The 32L axle powers the LA in the end.
  17. Zerobricks
    There is an internal rack under the bottom part of the arm, which is driven directly by a worm gear.
  18. Zerobricks
    Yes i have been thinking of the lxf file, will see :) Thanks!

    Few days ago I got an idea to make a telehandler, but doing it like TLG would. I thought of using a gearbox to control the functions via motors. I used a simillar, but improved mechanism like 8043 to control the 6 functions: Drive Front axle steering Rear axle steering Arm raise Arm extend Tilt the showel/fork The gearbox was placed on a 4x4 chassis and the whole thing is suspended with the hard springs. Here's the end result: Thanks to its short wheelbase, the model is very nimble. The gearbox operates the 6 functions. The arm can be extended some additional 20 studs via a worm gear. Also note the 2 LA's for lifting the boom. As mentioned earlier the machine has suspension: Notice the mini LA's used for steering: And the video: It can lift almost a kilogram, and the max height is somewhere arround 90 cm. The model itself is quite heavy, yet compact and even though there is only 1 M motor driving it, its still capable of going over bumps, etc.

    Pneumatics+compressor+pneumatics?
  21. Zerobricks
    Spring overdose! But seriously whats the maximum angle of the axle twist?
  22. Zerobricks
    Exactly!
  23. Zerobricks
    But from my experiences 8878 has less available current than the AAA battery box... Well you will see.
  24. Zerobricks
    You would need extension cable to connect it to the old 9V system

    Built some time arround 05: and even though not the worst, it failed the worst.
