    It is rather incomplete, switching connectors on the receiver should be shown, where the connectors in #3,4 will go? One of mine ESC's is plugged in the sound unit, how would that work?
    Thanks for clarifying this.

    • @HobbyconceptsLLC
      @HobbyconceptsLLC  3 года назад +1

      Just guessing because I have not seen one of the factory sound systems but I assume one speed control plugs into the sound system and then that sound system plugs into the receiver. Problem with that system is that the sound only follows one track. In any case the way I programmed is that the left track speed control plugs into channel 3 and the right track speed control plugs into channel 4. Whichever speed control is plugged into the sound unit would stay there and the sound unit for that track would plug into whichever channel that speed control would have been plugged into. The radio must have the newest firmware updates that gives it 4 mixes. Again not having seen one of those sound systems this is a guess. If you want further information email me (my email is in the video description) and send several high quality pictures of how everything is plugged in.

    Thank You very much for this lerning video. It was so clear to understand mixing channel options. So where did You find battery and charger, because in ebay all selling models are without batteyr and charger. i\It is required 3s 11.1 v Li-Po battery but capacuty is unnown to last more as it possible for this heavy machine. I also wnated to know how long does it last the 5000 Mah battery? What charger do You use?

    Thanks the programming help new dozer works much better.
    Not sure where the rc shop here in northern Alberta Canada got it.
    I believe supplier in China.
    Took 1.1/2 months to come in.
    Supposed to be new version came with lights and sound installed.
    Same backwards upside down programming.
    The pump ch5 slaved to blade and ripper very slow and weak.
    I checked the endpoint on ch5 it was preset at 60percent.
    I bumped it to 80 didn’t make much gain.
    And then seem like pump was running to hard when turned on.
    So I backed it off to 70.
    Any thoughts on more program tips on these machines and radios like which better setting for trim sub trim or trim?

  • @gratd981
    @gratd981 5 месяцев назад

    I have a question. I followed the instructions perfectly, but when I go forward, the dozer turns. And when I turn, it goes straight. Which makes no sense. So I set channel 4 back to normal instead of reverse, and it appears to have fixed it. Is it possible that the right track, or track 4 was wired in reverse at the factory? I still need to try it properly on the ground.

    What a thoroughly excellent video! I don't know if it was intentional or coincidental, but a real Cat D10T is set up exactly as you have done, where the driving is controlled by the left joystick, and the blade movements are controlled by the right one. I'm going to set up my DXR2 just this way. Thanks!

    @19:08 Not super familiar with this brand of Remote ( or rather the OS running on it ) since I'm more of a former -OpenTX- / current *_EdgeTX_* person.
    Maybe it's because of the slow reaction time of the screen but it looks like CH5 is _proportionally_ tied to CH1/2? Obviously if you don't crank the Stick of CH1/2 to the max then CH5 won't run at full power either ( as compared to manually triggering it ). Does the OS support the ability to crank CH5 to its MAX value regardless of CH1/2's position ( well obviously only once they come out of their dead zones )? 🤔
    Doing it like that is how I'd probably set it up on my *_FrSky_*_ Horus X12S_

    Ok. I know this is model world we are talking about LOL! Though in real world Dozer operation the turning that you are implying programing into your Toy! Is not even in any case the way a modern dozer and even old iron like a dresser td25 turn they speed up the outer track or slow the inner track moving forward, Reason is to not loose power in a push turn situation!

    I kinda want to get my hands on one of these, a Toyan inline twin, and combining the two. I just wonder if I can find hydraulic motors small enough to drive the tracks with. If I can, I'm thinking the engine will be attached to a helicopter governor and set to either idle or maintain a given speed, be belted to the hydraulic pump, and then everything else on the machine is run hydraulically.

    Thank you Bob, I have two of these dozers we use on our float for parades. I was just about to install Sabertooth motor controllers to enable on stick travel operation, I will try the mixing. I also had tried to mix the pump to the hydraulic operation, but not the way you demonstrated. So, that is today's exercise. One note: if you want to run this for several hours, you may want to open the final drive cap and loctite the screws holding the drive cap and the internal plate that has countersunk screws. That failed on one of our dozers and it destroyed the final drive planetary. Had to buy two replacement final drives from Eagle and that was a $500 repair. Also, there is a guy in Austalia that tig welds up new blades that are correct for this dozer. He also builds the correct handrails.

I found your video very easy to understand how to reprogram it so it works like the real deal? After doing that I wanted to use my new Radiomaster TX16S open TX radio and this helped a lot for the mixing, BUT with an open TX system the mixing is way more complex because you can do so much more with and Radio using Open TX system. You know I would like to see a video using an open TX system and programming to work with the Beier Sound module USM-RC-2, especially using a rotary knob to control the module volume??

    I used your video to set my dozer up the same way you did I love how it operates however first run about ten minutes in my driver side motor stopped running, I unplugged it for a few minutes and tried again it ran for a few minutes then shut down again. I went back and fourth with rc4wd for 3 months trying to resolve the issue settled on a replacement motor. I put it in it ran great for about two batteries then the other side did the same thing instead of dealing with rc4wd I’m looking at upgrading the motors do you have any suggestions or maybe something I overlooked? I set it up exactly like you showed in the video thanks.

      I had a dozer motor fail also. Those motors take a real beating in the dozer as a lot of load on them. CSMI makes a brushless upgrade, you might want to look at that.

    I will never own that machine only because there is no way I would want to hear that hydraulic pump screaming while working. I doubt a sound module on full volume would drown it out. Besides that Bob, love your channel and love your work.

      It sounds loud on the video but outside it does not sound that loud. Sound in the next video!

    I just got this dozer and was following the setup controls to set the radio in the same manner as in the video. I was able to get the blade and ripper to operate as in the video however the forward/reverse and turning controls are on the wrong axis (turning on the y axis and forward reverse on x), checked my programming multiple times and it appears to be the same as in the video. Any help would be appreciated.

      You could reverse the 2 plugs into the receiver. Double check the left track. Unplug the right track and make sure the left track goes fed/rev correctly.
