Mike, what is your prefered brand? Ihave a ASMP-61 that is waiting to be built, and a while back, I finally bought the stock retracts for it. They ended up going back and HPsaid the replacements had the same problem. This was a mechanical issue that left them setting like a chair with one short leg. Inever got to the actual operations of them

There is, or was one option for a motor driven system that operated just like a retract servo in that each retract plugged into a Y or splitter and everything was contained to the retreact and a servo lead. I"ve misplaced that companies name though. Also is there any build articles you know of for making such a retract..

Don
