RC Tank Warfare community hobby forum

My 6x6 will hopefully get converted to an 8x8 over the winter, would love a Russian tank transporter. Also thinking of getting another 4x4 to make a Fordson WOT 8, these were used by the Russians as Katayusha rocket launchers on lend lease. I scratch built one years ago, but the WPL truck would make an excellent base.

Converting it to servo steering makes a huge difference to the noise levels

Perfect base to modify. Think I am on truck number 14!

The first thing I do with one of these trucks is pull out the steering motor and the pcb. Install one of the Chinese esc's and a servo. It's very easy to do, the servo can either be hot glued in or mounted on a plate. One of the DasMikro sound cards can be installed to provide sound. These three items cost less then £30 and transform the way that the truck drives and sounds.

Bustephedon esc - Ebay
Any micro servo - Ebay.
DasMikro sound - Bangood.

The standard battery isn't bad really, you get a decent run time indoors with it, though a Lipo and a bigger motor turns it into a sprinter that will run all day long.

The suspension for the Maultier is the same as for the universal carrier which I designed many moons ago, here is the pic and scad code

Apologies for the crudeness of the code, it was my first design. For the wheels you need to print 2 and glue them together.

You’re a star Alwyn, I’ll be giving that a go

If you do go for the maultier you will probably need this as well for the extra track
https://www.plazajapan.com/495034496013 ... tUQAvD_BwE

You should be able o use the tamiya track and sprockets with the suspension I designed. The tamiya track isn't great but so long as you don't plan any heavy duty action with the model then it should be ok

Alwyn

Bloody hell Alwyn, that’s cheap, just ordered 3 because it would be rude to only buy 1 at that price

There are plenty of supp;liers
