gangster Posted December 14, 2008 Share Posted December 14, 2008 Ok, so whatever happened to linear servos,? why are they no longer popular and readily available.It cannot be size, the old Skyleader SRC1 were no bigger than a standard 148 type servo today, it cannot be cost either. In my opinion they were perfect ,why have a rotary movement to create a straight movement.?Your thoughts please Quote Link to comment Share on other sites More sharing options...

Peter Christy Posted December 15, 2008 Share Posted December 15, 2008 Yes, you didn't need to bother with servo reversing either! On my old Bonner Digimite, the servos are completely symmetrical. If you want to reverse it, you simply take it out, rotate throught 180 degrees and put it back!The "Microprop" servos used by Sprengbrook were pretty good too!And they were perfect for mounting in wings to drive conventional ailerons......!I've still got a few Dunhams servos that had both linear and rotary outputs!--Pete Quote Link to comment Share on other sites More sharing options...

John Schall Posted December 30, 2011 Share Posted December 30, 2011 Something to add about linear servo outputs, they are vulnerable to ingesting dirt and other debris, like sand. I used to do a lot of slope soaring at warren dunes state (michigan) park. Sand got into everything! I had to remover the linear racks and cover the slots with tape and use the rotary outputs. Open gimbals in the transmitter sticks proved equally susceptible to sand. Had to switch transmitters to fix that. To this day, I avoid open-gimbal TX's and linear rack servos. If nothing else the rotary output is resistant to ingesting dirt. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted December 30, 2011 Share Posted December 30, 2011 The rotary output also makes it easy to set up how much control movement you want as you can alter at both ends, not just the control horn. Try setting up a throttle with a linear servo! Quote Link to comment Share on other sites More sharing options...
