I used a pulse frequency of 400 and had no issues smooth as silk. I believe FrSky has servo frequency adjustments. see if you can adjust it to 250

I like orange juice too!

I got orange ones back in September. The orange looks kinda cheap. I like the new color better.

yes it will be more than you need due to the torque and the metal gears but better sfae than sorry

ITS A VERY GOOD SERVO, AND THE TORQUE ITS ENOUGH FOR AILERON RUDDER AND ELEVATOR,,,AND ITS REALLY THIN...

I have these in my HK DG-1000 & they work really well, plenty of torque & movement. I've used them in wings (aileron & flap) & elevator. The fit is almost spot on with the trailing edge of the aileron servos protruding about 1mm above the wing surface. You'd need a 9.5mm or less thick servo to fit perfectly.

10.5mm is seriously thin!!! and it's really small for a thin wing servo...!!

That's what I thought, it doesn't take a tone of cause the higher the speed the lower power that's needed to get jet to turn

Well, for a HET Jet OK, but you want this in a 120mm Jet right. Which Jet and what is the weight of it?

 erh7771 292 points

A scratch built A-4 Skyhawk ~74" long HOPEFULLY less than 11lbs. Not going to be doing fast spins in it etc. Split S, slow rolls, 8 point, inverted, Dives...medium range maneuvers.

 dw30z 86 points

With 1.5kg-1.75kg torque??? NO.

REALLY ITS STRONG ENOUGH, Y HAVE PROVE IT AND ITS GOOD...

 DOCA-SP 2834 points

Yes... It is metal gear.. it's possible to see this in the picture. I only think this servo is weak, only 1.75 kg. Other servos for wings have 4.2 kg of strength.

correctly...I thinks so. This Servo is not in used for big and fast Hotliners.

Why Orange? HK, please try black...it hides the dirt better www.link

most wing servos are hidden in the wing. you can always tape or paint?

Like orange traffic light : "Beware" !!! Would cross my finger for good review. Till then I would use the VG 1.5Kg ultra thin servos

 rsuarezn 173 points

Shure you had a good batch of VG servos. I thouught the same untill I received 4 totaly glitching units in the same order . Internal inspection showed that the the whiles from the pots to the pcb where all bad soldered and un isolated (as oposed to the good ones) . Sooooooooo the question is INEXISTENT QUALITY CONTROL !.Ah and these ones at least have fixings , VGs must be bonded . Yellow is no problem for me either.

 rsuarezn 173 points

Have no other items that I want to buy from HK , otherwize I would have bought a pair to test (and post a Review ) . Whos the first one ????

I use these on my 2500 mm reaper now i have good about 8 lbs total craft weight and these servos have no problem holding the elevator i use them for flaps as well and they work great only thing is if u do buy it dont rely on only the screw use a good glue to hold the flat part to the wing as they screws will get loose over time hope this help

Does anyone know what size the horn screw is? And what sturdier horns will fit them please?

 Jimbello 8 points

The screw size is 2 mm. I just got two of them and they have a lot of gear backlash. Approx 2 deg. measured! Also, the output bearing is sloppy in the housing, either that, or the bearing itself has lots of lateral play.
I have yet to power them up.
Not looking good so far!

 Jimbello 8 points

They will be easy to fit with external bearings, which will reduce the bearing side lash. They seem to centre well and operate smoothly. Just have to contend with the gear backlash using short servo horn/long control surface horn.
