    Application(s):

    Mini Stick, 57" P-51 Foamie FMS warbird, 36" depron Slo-Buddy.

    Comments:

    Used in mini ultra stick and 57" p-51 foamie and after 5 flights so far no problems. I also have them in a slo-buddy over a month and 30 flights, again no problems. I get them at toysonics.com for $2.59 and out of the last 8 one was bad from the factory but they replaced it for free. I think for the price they are great.

    Comments:

    Good little servo and cheap enough to throw away when they break (on lightweight applications, they don't break often). I don't trust these on expensive planes where I need accuracy, but you can't beat them for the price on foamies.

    I found these servos to work really well for the price. Yes there are other high-end servos that may be a little better but you can't beat the price of these servos and they are only 9 grams in weight. I got mine from Amazon.com with free 2-day shipping. They work great with Arduino and the Servo library with Arduino is easy to use with them.

    Application(s):

    Passive mechatronic display, new project.

    Comments:

    I am developing a project were it will need some kind of lever action. So I am testing with SG90.
    Before putting them on work, I tested two of them for about 130.000 cycles, without load, at one cyle per second, and 70 degrees travel.
    Just to see the control pot wear.
    At final, one had no problem, and the other after 110.000 cycles, stops at one end of travel.
    Anyway they seems to be very thrustable to normal use.

    Put two SG90 servos on the ailerons of a Carl Goldberg Tiger 2 (62 inch span and OS35AX) in 2009 and they are still flying today.

    Comments:

    Was going to replace them but the shafts are still in good shape with no play. These are surprisingly long lasting servos as the plane has flown weekly for almost 5 years with aggressive aerobatics.

    i have used this servo for pick and place mechanism. after couple of runs it is just dead and it does not respond

    Application(s):

    Track switching and gate control with plastic low weight materials.

    Comments:

    I used this servo for the application of railway track switching and gate control in my latest project which found to be very worthy for its low price and size.

    Comments:

    This tiny servo presents good performance - speed is OK and as a vintage servos user I think the torque is impressive - for an incredible price (less than 2 euros sending cost included!)
    I don't have a lot of sight on how their life is long, but I haven't any complaints for now on...

    Application(s):

    Magnet rotation for robotic project

    Comments:

    I couldn't make it rotate 180 degrees. Mine only worked 90 degrees. From 0 to 90 clockwise. It didn't go counterclockwise at all. Servo didn't listen signals over 1300 mS. it forked only in range 500-1300. These are the cheapest servos you can get (2-3$). And when you need a lot that would be the way to go. I'm trying to figure how stable these servos are and how prone they are to malfunction.
