Dragline Rebuild

Lots of fooling around getting that gear train right eh?
I never needed the flywheel because I can program the ramp up on the motor with the settings on my motor drive boards. They can be set from 0-20sec. to ramp up to full rpm then down, "regen to stop" or, "coast to stop" Without, you get a big pendulum swinging back and forth I also have my radio sticks set up on a curve to ramp up. I may try the flywheel someday just to see how that would work.

I used one of those doohickeys that slow down servo speeds. It gives the same slow acceleration/deceleration with a continuous rotation servo and it tamed my crane down nicely for much more scale operation.

Yes steve-it took some time to get those gears right. The flywheel works well for me but you are doing the same thing with electronics. Todays electronics work so good that I thought about getting a radio and-3-esc's and be done with it but I am going to try to keep it the old-style manual controls.
