1:50 Dragline

Two pretty short videos. Almost had decided not to use the footage but what the heck.

I finished loading all four sand barges with the crane and conveyor so thought I might as well push them around the pond!

The crane barge is a prototype/work in progress. Wanted to see how it looked in the water with the crane on it. Shoud be a bit wider so it fits tight in the lock chamber, and probably a bit longer would look better. I had just finished pushing the loaded sand barges and my piloting was a bit too fast and overpowered when I tied onto the crane barge.

I am in the middle of a refit/overhaul of the little 1:50 Menck dragline. It was initially setup using micro servos converted to continuous rotation. I was thinking about using micro gear motors and speed controllers but it uses three motors in the house for drag, hoist and swing. There is also a servo in the undercarriage for locomotion.

My question, has anyone used a micro sized motor controller designed for quad copters to control brushed motors?

I'm starting to search for that now, but if someone has already done something along that line it might save me a bit of searching. I would like to use four of the pololu micro gear motors in the house and add boom control.
