Arced Digital Micro Servo
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 3¦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: 0.6kg/cm (Dynamic torque***)
Accurate neutral position
Very narrow dead band (<3us)
Inbuilt Fail safe (holds position if lost signal)
Futaba AVCS Gyro DS Mode conpliant.
Comes with horns!
This is a v2 servo. It has the following improvements;
-Much broader voltage range 3~6v
-Works with all power systems ESC/BEC, UBEC, NiMH/NiCd
-Torque is improved to .60kg DYNAMIC. Dynamic torque is the weight at which the servo can move the arms. Unlike stall torque which is a higher weight, yet means the servo arm cannot move.
These servos should not be run at 6v for extended periods, as this can damage the micro coreless motor. Please use 4.8~5.4v for a longer lasting servo.

good servos... but very delicate...smooth and accurate . i see a lot of bad reviews, but i have no complaints. you must be careful installing/adjusting linkage and servo horn, the gears are that delicate.
NEVER force movement of servo horn/gears or it over johnny.J'ai achet plusieurs servos ARCED dont des D531bb D541bb et ai toujours eu des problmes. Blocages, pignons non aligns, patinages, accoups, rotation permanente!. Ils sont instables au repos, bruyants et consomment plus que des analogiques.
La mcanique de base est celle des "Arrow" mais sont moins biens monts.
Waste of money.Hi,
this is the second time i buy them, last time was one year ago. Both times they worked totally perfect, cant say anything bad about them (okay, theyre loud, but all digital servos are louder than normal ones). Theyre fast, accurate and light (okay, 4,9gr. - 0,5 more than advertised).
I use them in an 125gr. Indoor plane (Knuffel) - and i test them hardly (crashs...) - no problem!
I will buy more - thanks UH!!realy good servo.good acuracy , speed ...
super fast responce but dont overwork them or they will wear out quick other than that they are great i would recomend to all heli useswaste of money, the first one was broken immediately and the second one after short periood of time. Inexact and inaccurate movement.Garbage. I bought six, none work. I am using a Spektrum radio, but I don't think that should matter. All they do is twitch a little, no response to stick movement.Lightweight, fast, fairly precise and perhaps most importantly (to me at least), they center well. However, the reliability is a big issue. As I and my clubmates have found out, many doesn't work out of the box or break down after almost no use at all.
If you are lucky enough to get a good batch then they will serve you well. Although the chances of that happening is unfortunately not terribly good.Sur 6 servos D541BB Digi-v2-Micro commands et essays, seulement 4 fonctionnent. Les 2 autres restent bloqus lorsqu'ils sont actionns. Dommage, ils sont vraiment trs rapides, trop peut-tre !j'en ai achet 2, crams au bout de 15 secondes !
videmment il faut les renvoyer...
je suis plus que dsapoint et tonn. Certains sont parfaitement satisfaits et d'autres ont des problmes pas possibles. s'il faut coller les pignons sur les axes la cyano avant de s'en servir il faut le prciser sur la notice ou les vendre en kit ! je ne renouvelle pas l'exprience merci bien !
