Got the tracks refit with steel pins. And, put the 1000:1 gear motors on it.
I think is is just a bit slow now, not much but a bit, especially in reverse?

Re: He is at it again! 1:50 Dozer Conversion
I'm not totally sure about the time but I estimate 4 or 5 hours. The nubs cast on the inner part poked into the hole of the outer tread in front of it. They were never that tight to start with.

Re: He is at it again! 1:50 Dozer Conversion
Started working on the track upgrade yesterday. I'm drilling out the cast pins and thru both part. Then 1/16" piano wire goes in place. The two pictures show the slop due to wear of the pins cast...

Re: He is at it again! 1:50 Dozer Conversion
Tom,
I agree on both counts. I plan to run this way for a few hours and try to tune them down and see if it still pushes good. I get mush better and more realistic look when I get up close and...

Re: He is at it again! 1:50 Dozer Conversion

I haven't had enough run time without a gearbox failure to tell how the beveled sprockets are working. I don't see how it won't help some? They way I figure it, there is less surface...

Re: He is at it again! 1:50 Dozer Conversion

I'm still trying different motor and battery combinations. With the speed controllers I can easily fit two 500 - 3 cell lips under the hood. I hope the ESC's...
