These are really good servos. I use them on my mostly alignized FL HK 500. At first I noticed there was a bit of overshoot, and then I noticed it wasn't because of the servos, it was because the tail boom of the helicopter twisting around towards the ground. When the helicopter is set up properly, these servos work fantastic for hard 3d at 2650 RPM. 4 stars on value, because I cannot find replacement gears for these servos. Once you strip a gear, you have to buy a new servo. All I can find is that these servos are probably made by Savox, and they do not sell these servos, or any version of this servo, which means we're not likely to see replacement gears any time soon.

I am using these as cyclic servos in an Align T-Rex 500 ESP converted to flybarless with an Align 3gx (and also converted to belt drive). These are replacing the original Align DS510s that came with the kit which were pretty mangled due to a really bad crash.

Two of the three Rotorstar servos had zero slop, but one had a little give. They all centered well and move at the same speed. There is no hunting in any of the servos. The gears are all metal. They are at least as precise as the DS510s and the splines are compatible with the DS510s servo arms. I have had 4 flights so far and the servos have given me no trouble and are more than fast and strong enough for sport flying/ light 3d. Overall I am happy with the purchase so far. The only reason I am giving an overall rating of 4 stars is due to the slight slop in one of the servos.

Worked just fine out of the tin case. Specs for size and weight are correct. Takes 25 tooth servo horn (futaba servo saver fit on perfect) and has a 26cm servo lead. Very quiet running with both servo tester and radio bench test (at all frame rates). No gear train slop at all. Going to use as a 1/12 scale steering servo. Now to figure out what to use the cool tin case for...
