I have allready been working on this off an on for about a week.Started off by striping the tracks and all the internal parts.The nice thing about the road wheels is they were put on the tank in two pieces and not glued.This is helpfull because they need to be cut down 1/4 inch in order to fit the tiger tracks.I used a hobby type saw you will see in the pictures with a 1/4 inch square piece of key-stock taped to the saw on both ends to get my 1/4 inch space for cutting off the flange on the wheels.Its not rocket science and does a fairly accurate cut if you cut slowly.Then I glued the two halves togeather,both inside and on the outside of the spindle shaft.It makes a very solid wheel.I lube the spindle shaft and reinstall the wheels.There are 16 wheels and I will be using 14 of them and will have 2 for spares if needed down the road.The very front two will not be used because there will be four motor boxes installed and no idlers will be required.

I will be using two of the stock battery's.I cut out the top of the battery box and cut out pieces of sheet plastic to raise the height of the battery box,then reframed the box.two batterys fit nicely laying on their sides.After wiring is completed for the battery connectors the top lid that was cut from sheet plastic was glued to the top to complete the box.The batterys can now be accessed through the battery cover on the belly of the tank.

A note here about the switches and battery charging jacks.(on all my tanks I move the on-off switches to an easy accessable area on the back of the tank,a charging jack is spliced into the leads to the battery and usually just hangs out the back of my tanks.)
Now I know most guys on here try to hide the charging devices they install to preserve the authenic apearence of their tanks,that is a good way to do it but don't matter to me.Don't like turning my tanks over to turn them on or off and have to open the battery compartment to charge a battery.

On the back of the tank hull is where the on-off switch is located,along with two other switches I installed for the batterys.Each battery will have its own switch on the positive leg,and the wire from each off those switches goes to the in "side" of the main on-off switch.Each battery has its own charging jack,therefore the reason for the two additional switches.Each battery can be isolated for charging purposes and I can also use one battery or both batterys at the same time while operating the tank.Will most likely use both at the same time for operation.
