I bought 6 of these and two quiet setting them up to center them on the bench. Not sure I wan't to use the them at all now. I don't think its worth the change.
Stay away from these...Servo attachments are breaking. I brought 6 servos.. all of them damaged.. HK has to correct this quality issue...This servo has more travel in one direction then the other. Not sure why. never encountered a servo like this. Not suitable for cars/trucks as you have more steering in one direction. Even says so in the description "Operating Travel: 40/one side " my badd,, it is quality made servo, and has great torque, but besides that ONE MAJOR flaw it would have been great LOL be warned!Otimo produto! Recomendo a compra!!This is a really Stron Servo and a Bargain Price if your looking for a Stong pull servo this is your guy.
However you may have a say when it comes to Time response. So if you want to fit it in a plane or HELI you may want to go for something with a very low response time ex. 0.05s.
It's all up to you :^)Tolles Servo fr kleines Geld, an 2S echt stark, verwende 7 Stck von diesen Servos in meiner Piper und ich bin wirklich zufrieden damit.Servo forte, porm pouco preciso. No centra bem. Instalei no meu sbach 30 cc e vou trocar, pois no ficou bom.Man this servo is strong, i put it into my Ofna ultra LX2e and it worked great! very recommended upgrade!All metal gear box!
Gears are well silicon grease lubricated!
Ball bearings - 2pcs
Solid PCB w direct soldered motor.
- power grom LiFe 2500mah 2S = 6.6 nom.V;
- servo arm - metal futaba style;
- load weight 4.5 kg at 2 cm leg = 9kg/cm;
- servo is side mounted;
- the weight ballast is on the ground when the arm is in full down position = 0 load;
The servo can hold up to 80 continuous cycles after that the board and motor are overheated! At Holding position - 0.6A. At start position - 1.2A
The work cycles was with 4kg/cm, 1sec pause between cycles, 500 cycles in series with 1 hour pause.
Total count cycles = 30000 till brushes of the motor burn !!!!
No any damadge to the gear box!! Additional loop in the gears is normal!bardzo mocne i precyzyjne serwo,nie jest zbyt szybkie ale do BUGGY 1/8 moe by.szkoda e s tylko dwie dwignie,jednak mona dopasowa od TURNIGY lub BLUEBIRD.polecam!!
