Sorry for duplicated posting.
No probelm, RCU has lots of storage space. (and grubbins to edit dupes)
But I am not in that position nor do I have the time or equipment to experiment, so I found it much easier to ditch the drive system altogether and fit a servo to each. Simple, reliable, does nto need an extra battery due to acceptably low current even if stalled. And lots of reserve torque.
Got a picture or two? I'd like to salvage the two sets I've got somehow.
