The child test went very well. They managed to break a link in an aging set of Kenny Kong tracks but did not manage to hurt the transmissions at all. In the past, with stock transmissions, track links did not break when a pebble was ingested by the track system, the transmission broke. I do not know if vids were made of the event, we were too busy making sure the children didn't manage to run one off the edge of the cliffs down to the water among other duties. A tear down after the even revealed no wear or damage at all to the transmissions.
As for fitting in the Sherm with the Mato suspension, can someone tell me if the Mato drive sprocket is the same as the HL P3? If so, I can make that happen with a little time. I also need the exact dimensions of the final drive shafts, the distance end to end installed in the tank. A photo of the sprockets and transmissions with the final drive installed would be grand also.
