Could someone help me also under the same heading. I am thinking about getting a Bobcat XL with a Jetcat P-120 (detuned to 17lbs.) Here's the problem, I sold one of my IMAC 33% Edges for the Bobcat and have a trunkful of JR servos and would like to know if they would work in place of the recommendations. I have four 8411's (MG), four 2721's(MG), and six 4721's<--all are standard-sized. These are all very high torque and very expensive so I would like to use them if at all possible. Thanks for your input in advance. John Lubbock TX
