I cannot believe how many people rated five stars for this garbage! They are blind or I'm not lucky. I got today six servos and they are totally scrap. Not one or two....all of SIX! They all have huge free play, I cannot imagine even I'll decide put them in my plane. Waste money...Excellent servo for models buses of indoor, wonderful by their dimensions, features and performance, excellent design.I strongly recommend it.These servos are ideal for small park flyers and scratch indoor models. Not very good centering, but worth that price.exelentlittle servo have bought about 20 and only had one with bad centring speed is even better than my d4,7 s servos exellentThe best serwos for indoor planes. Very strong and low weight. i have HXT500 to but this serwo is much better.Great light weight servo!
On the sticker they say "Ball Bearing Type", but it has actually NO ball bearing.
The torque seems to be higher than specified (feeling, no tool to check), but the speed is much slower. About 0.25sec/60deg @5.2V(measured with Jeti box), NOT 0.11sec!!! (maybe the specified speed is measured for 30deg...).
Little play, but acceptable for a servo of this size.
I will buy more.Installed the servo in a shocky from ikarus. it's powerfull and the zero position is very good.
it's also heavier 4 servo's without horn and screws are 13 gram
I recommend als the turniky 2204-14T outrunner as motor for the shockiesOne of my favorite small servos!! works great in my 80 gram AUW 3d depron milled foamy, with lightened dymond 47's and a phoenix 10 micro esc, mighty midget brushless 13-6-9 turn with a 6x3 prop on 2 fullriver 250 cells and a blue arrow micro jst 4 channel recieverI have one of this servo.. its an very good one!!!
Eu tenho um servo deste... muito bom!!!
