May 26, 2019Application(s): Align Trex 700L 700mx120HV.
Comments: Great servo, chip and solid. I have a lot of flights on it without any issues.

November 1, 2012Application(s): Tail rotor in 600 and 700 electric helis.
Comments: Pretty poor compared to any of the 760 us servos. I was not able to get great results with it. You can buy a Futaba DS9256 for the same money (used) and that one is so much better. MUCH better is MKS DS760.

Comments: I use DS650 in my Raptor 90 for the throttle servo - love it. The Gov is the Futaba GV-1 running at 5.2 volts.

September 16, 2011Application(s): Trex 700e v2 tail servo
Comments: I flew 3 flights, tail drifted in invert hover and waged in upright flight. When I got home servo would never move again. Completely dead. The align ds650 died or something. I checked all of the wiring and plug it other channels but could not find anything wrong. At least it died when I was on the ground. Don't know what happened, this is a first for me after having several heils and planes.

September 30, 2010Application(s): Tail TREX 700 Nitro Flybarless FL760 Align
Comments: Installed OK, setup OK. However not yet flown or even started heli ever. Problem was I had to reduce lipo battery to a store charge by leaving receiver and TX on for about half an hour or so. Note. my charger does not have a store function. Anyway DS650 servo died. No life whatsoever. Now no pressure was put on the servo, it just sat there Importer said Align does not have a good reputation on honouring warranty but I suppose it could have failed in mid air so I consider myself lucky this DS650 failed on ground. Shop only had a DS620 in stock.

July 13, 2010Application(s): Tail rotor servo Trex600
Comments: Love this servo I've made it my choice on all my helis. It is performing well on my 550, 600, 700 helicopters. The price is awesome the servos are holding up. All servos fail at some point.
