Guys

ES579 is JR's numbers at 6.0v 9.5kg metal gear non digital.
I'd use JR 362 on the UP3, UP 6 can work the midi size servos quite hard, so maybe use two 3401's (3421's) to match the install?

Sure I have the loop pattern here somewhere. pm me a fax number if you have one, third world in my office and no scanner hooked up ;-)
