Arced Digital Micro Servo
Arced make the lightest and smallest digital servos in the world!
With a high fidelity MCU and an excellent algorithm, youre assured of a smooth operation and less noise interuptions.
Frequency Conversion Technology keeps the servo cooler under demanding 3D and helicopter flight, whilst also keeping power consumption low.
Arced Digital Servo adopts Frequency Conversion Technology which makes it remain cool under wild and extended 3D flight and keeps power consumption rather low.
Extremely narrow dead band (¡Ü 4¦Ìs) realizes industry leading sensitivity.
Fail safe feature (Lost Signal Protection) --- Arced Digital Servo holds its position and torque during occasional signal lost.
Full AVCS Gyro DS mode compliant
Light weight but durable structure will not interfere the 3D maneuverability of your plane.
Spec @ 4.8v
Torque: 1.3kg/cm (Dynamic torque)
Accurate neutral position
Very narrow dead band (<4us)
Inbuilt Fail safe (holds position if lost signal)
Futaba AVCS Gyro DS Mode conpliant.
Comes with horns!
This is a v3 servo. It has the following improvements;
-Much broader voltage range 3~6v
-Works with all power systems ESC/BEC, UBEC, NiMH/NiCd
Very good digital servo for the price. Quick, strong, centers well, holds position, no glitches, much better than Corona. Less resolution than top digital servos, but hey, they cost four times more.I purchased 3 of the D591 servo and so far very happy with the performance and the value. It replaced my HS-81 on the tail of my Trex paired with a GY401. The D591 did work in digital mode but the tail seemed to hunt. Will try again on a different heli setup. The D591 did very well on my small aircraft setups...just do NOT over drive them (as stated in other reviews)Quick, strong and low max current(200mA)- really frequency conversion digital servo.
But max pulse width is 2ms, after this the servo steps to end. Like potentiometer center and servo 1.5ms positions are not same. Maybe it's occasional defect. I have only one servo.Very good digital servo for the price. Being just 9grams they are Perfect for Park flyer's. They are Quick, strong, centers well and holds position. I had no glitches. I replaced a couple of full size servos in a large balsa plane and they did the job just fine. I will buy more of these are great little servos.Great servo for that price, but doesn't work at 6V (4 AA batteries) and the servo way is limited to 135%.
Gutes Servo zu dem Preis, leider funktioniert das Servo berhaupt nicht an 6V - also 4 Mignon Batterien. Bei 5V (was die meisten BECs haben) gibt es jedoch keine Probleme. Die Wege sind auf 135% (sicher 125%) (Graupner/JR Wege) limitiert, daher nicht geeignet fr Delta-Modell (FunJet z.B.) Stellgenauigkeit ist digital-like super, die Anschlusskabel sind etwas kurz. Verarbeitung ist noch gut. Leider noch keine Langzeiterfahrungen vorhanden.Worked for a day or two and then quit. I was using on my HBK2 with a HH gyro.Great item.
The digital servo works fine.
Good cheap.Trs bon servos,je suis trs contentTrs bon servos,je suis trs content.I use this in my trex 450, the tail is even more rock solid with this servo than the old HS-50 I used to have in it.
