D11 New Project

Here is another vid showing a bit of power pushing a trolley (about 40kg) on concrete.
The blade weighs nearly 4kg on it's own(steel) and I think this is the issue for turning as when the blade is off turning is no problem. The new blade will be made from ali and will weigh about 1 kg. I also have put a lipo 14.8v battery on board to try to get better performance. Testing continues.

I'm not sure what would cause the voltage drop. I know that happens with my Volvo occasionally because the slew ring I made doesn't always make good contact but I doubt a wiring connection is your problem. I have learned the hard way though that it takes a tremendous amount of power to turn a heavy model on grass or carpet. You may find that your motors are just not up to snuff. The machine looks awesome though and seems to function perfectly on smooth concrete so I'm sure if you can up the power somehow it will be fantastic!

Thanks Reg,
I now have 4s lipo and have set the speed controller to 100%, so at full charge on the battery I get 16.3v. This has made a big difference. The speed is too fast for scale so a change in gear ratio is coming in the next week or so. I am waiting for a delivery from Germany for some new gears from my friend.
This will make the scale speed better and have a lot more torque.
Here is a new video. Hope you like it.

Hello Paul very nice video. I't a shame you can't put a hi and low speed in your drive system. I believe dirtpusher 9 used drill motors and used the hi and low system from them and from what I seen it worked great. LilGiants Joe has the dozer now. That way you would have the fast speed when traveling and a low speed when pushing. Ed

Looking good! Looks like you need to get some wear on those tracks so that they hang a little more...sounds like a great excuse to run the **** out of it to me! I'm sure the gearing change will get you right where you want to be. Keep posting updates!
