This is a very nice micro servo. Its strength and speed vs weight is unparalleled by any other micro servo I've found. The output shaft is free to turn 360 degrees but the controller will only rotate it about +/- 50 degrees. I was hoping it would achieve +/- 90 to be used on a robot. I connected it to an Arduino and used the writeMicroseconds command to try out of range values and it still only turns +/- 50 degrees. I disassembled one to check the construction quality. All the gears are metal and there are two ball bearings supporting the output shaft. The potentiometer was 1800 ohms with a 2.5V reference voltage and over 180 deg of useable rotation. In theory this digital servo should be programmable to modify the angular limits but I couldn't find any documentation. There are 4 SOT23 transistors on the circuit board that appear to be a full discrete H-Bridge driving the motor. The control horns felt a little loose and the spline would occasionally slip if stalled. The midsection of the housing does appear to be made of some kind of metal. I was able to solvent weld a small piece of ABS to the bottom plate using acetone so the top and bottom plates are likely made of ABS. I really like this servo and would buy many more if there was a way to increase the rotation angle.

I ordered these servos for my outdoor foamy airplanes. The D0576HT weighs 8.2 g without servo arm and center screw measured on a digital gram scale. It is listed as 7.9g but I tried weighing 2 pcs and got 8.2g. The servo comes with an assortment of servo arms and I was pleasantly surprised that one of them was extra long. Fit for a 3d foamy. I used to have to make phenolic horn extensions as the D074 from Inservos didn't come with the long servo arm. Nice job BlueArrow. I powered it up with a LiFe 6.6V battery to check if it was working. No problems. My initial findings are the D0576HT is very fast, faster than the D0474 and centered well. Torque specs are impressive and I can't wait to install these servos in my 3d plane.

those servos are mighty ,super fast super strong,well made ,they have some slack after a while ,barely noticeable ,suggested

i will never buy from banggood again, delivery real super, super long, im not really bather to test if it works because i already bought it from another store way after i order this and it came way before
