Tom,
Thanks for the comments. I hadn't heard from you in a while, wondered how you were getting along. We are coming to Florence in a few days to check on the boat.
I haven't done anything to the wood crane since we got back from PA. I still need to paint it and I want to rebuild the cab. I slapped on a balsa cab but it needs to look better than it turned out.
I ordered some stronger versions of the gear motors that should make the dozer work really good. I have a few more details to take care of but I basically have the aluminum rear end finished and tested it yesterday. Works good but the low power motors I have on it no are just a bit to weak and they stall just about when it should start to slide a track.
I also ordered some new speed controls that I hope are smaller than the HK xcar 45 ones that I'm now using. They are just big enough that it is hard to cram it all under the hood.
Here is a pic of the chassis mod.
