I found that the M-16 drives well on mostly flat smooth ground, especally when loaded heavy.

as a result I made a few small changes to mine, 1st I removed the battery box off the bottom, I installed a lipo 2250mah 7.4v in its place.
I also installed a battery alarm/monitor as well.

This has greatly improved mobility. I also made a mod kit and mounted a 20mm Flak 38 cannon in place of the 75mm pak40.

Makes for a better nusiance weapon. The new 20mm has working elevation as well as azmith.

Vehicle is set as light armor and will take 3 hits, reload time is 2 sec, should make for a nasty customer.

I also packed the drive diff with a heavy grease to improve traction, both tracks tend to drive together better and yet will still corner.

1st terrain tests showed that in many cases only one track was driving and the other was not, the loose track would just spin and no movement on the one with traction.
