Corona CS238MG Metal Gear Servo 4.6kg / 0.14sec / 22g

Good little servo, they center very fine.

I picked up two to replace a pair of name brand servos of nearly identical size and specs that buzzed no matter the flap position, hoping for the best. Success! They are smooth, quiet, nearly backlash free. center very well, and NO BUZZ. Mine must be updated versions as the arms fit tight, almost too tight. At under half the price of the name brand they perform much better in my application. Very happy with them so far.

Got 3 of them, good, very strong, ball bearing and metal gear, good center return. One of mine works good but makes a “grinding” noise. Unassembled, seems ok, but the noise did not stop. Will use it on the tow hook, to reduce risks of failure. Other 2 work good. Very nice the orizontal mount. If you buy this, grab 1 extra.

Great little servo. Running one of these for both ailerons on my combat planes (3). Stands up to a lot of rough treatment. Excellent value.

Really happy with these for the price. They are strong, quick, and seem precise. I'm using 4 of these in a Sundowner 36 pylon racer, and they have been great so far. They fit perfectly (just slightly fat for the wings, but they fit with some sanding). Precision and resolution are important for a pylon racer where control throws are small, and I've had no problems with these. The plane flies perfectly straight every time the controls are released, and resolution seems good even at small throws. I haven't put on enough flights to judge reliability, but the first several flights have been fantastic. I would definitely buy these again for that "grey area" between a 9g servo and a full size servo.

I,ve bought 4 units and I can tell all of them fit very well with arms, no tolerance between gear and arm.

Fast shipping, good quality

I have a bunch of these servos and have yet to have one not work perfectly. I have snapped a number of servo arms in combat though and can't find replacements. any of you know what type of servo arm the CS238MG takes? If replacements are available I give this 5 stars. If not, I will no longer purchase Corona servos.

I have old serwo SC238MG with the red inscription Corona. It has well-fitting T-bar lift well. New with the orange inscription are loose. This is not the problem, some tape and it is well. New serwa work so as old, well. ( I always unscrew the casing and check the solder).
