Very happy with these. Very fast and very strong. No problems centering or with jittering.
Servo arm gears are a little soft. Will hold up for nearly all situations, but it is there. However, I'd rather strip a servo arm than the gears themselves. Planning on buying more of these for future projects. Great value for the money.Ordered on Wedensday, arrived from aus wharehouse on Friday morning. Look & feel are solid, control horns can't be bent like most cheaper ones. Torque at 6v was ok, they could be stalled by hand but couldn't be moved from a resting position easily. I think I would have broken something if I tried any harder. Case is held together by 6 x hex head screws. a very slight amount of moverment in the gears - you can feel it but hard to see it. Operation is fairly quite, they sing a little when you try to move them by hand which is normal but also quite. Resolution is great, I expected lots of jumps between positions but nothing the eye can see. 3 horns are included, X, straight and round. Pre drilled holes in the horns are approx 3mm or slightly less. Price is very reasonable for a servo this size, lets hope they work as well as my previous BB servos some of which have had 500 flights without any issues or slop. I'll report back when these have had a few flights.I wasn't really need of another servo but it was on sale and I am sure I find use for it. Quality seem great and half the price it's a steal. Only time will tell how robust it is but for now I'm happy!I have 4 of these to go in my 1/4 scale Piper Brave.
On special so the value is outstanding for brushless.
Smooth with very good resolution, tight gear train, love the wide voltage capability.
Very robust. Like all the standard size brushless they are a few grams heavy than coreless but in a big plane it doesn't matter.
Not flown yet but they test very well. Impressed.I Bought 3 of them, all them passed in the Hitec Servo Tester, strong , fast, quiet well made, centering very well.
Will be installed in the rudder and elevator of Great Planes Reactor 55cc.
I had before there, 3 TGY-1267HV Titanium BB/DS/MG Servo14kg / .10sec / 57g no problem at all, but I am worried because have been doing very hard 3D manouvers and the plane weigh 14kg so,I decided put something stronger.
I will post if something go wrong.
