I spent a couple of hours on this again late this afternoon. I can see why people convert these all the time. It is quite simple. Today's plan was to get it swinging and it went very easy. I machined the excavator's pieces to fit around the 360 servo providing a nice tight fit. I'm not sure what pitch the ring gear is but I was able to find a suitable pinion in my junk after a lot of searching. A couple of quick mods had it bolted to the servo and the house spinning! I'm not sure what I will tackle next. I will probably finish all of the stuff up top before buttoning up the track frames but we'll see.

Thanks for looking.

Looking good....hey was that ring gear on the model....if so how did you get so lucky with finding a small gear for the sevo that had the right pitch???

Where did you get that little slip ring....I could have used one just a bit bigger for something.....lol....ended up making one from scratch and I hope it works.

Thanks KP. It's been pretty simple so far and I hope it stays that way! The only time I enjoy these conversions is when they go smooth and fast. The ring gear is from a heli. I modified it to fit and bolted it to the track frame. The gear was a pinion off of a 540 motor with a 1/8 D shaft. I drilled out one end on the lathe to fit the servo tight then drilled through with a 1/8 bit removing the D. Flipped it around and machined a relief in the other end to hide the head of the mounting screw. The slip ring is from Robot Shop. I bought it almost two years ago for $18. I've since learned how to shop on eBay and realized that I got ripped off at $18.lol It wouldn't be heavy enough to run your lighting on the PC1800 let alone the tracks. Carry on with the scratch building sir!

A bit more progress.... I need to get a couple more cheap ESC's for the tracks.
