What I do not like is that at such loads servo won't move but the arm stays steady, trying to move it on opposite direction stalls.
Some data for reference
Turnigy 620DMG: stall 2,5Amps 5kg 1A 6kg 1,7A
Vigor VSD-18MB stall 2,5Amps 5kg 1A 6kg 1A At 4kg load the VSD's arm moves, but has less narrow band compared to the other 2.
P.S. I am not the best bench-tester.

Great low profile servo. Much better than the Bluebird ones. I had to replace some faulty Bluebird servos. It is a great choice. Low noise, strong and no chittering searching for the center.

Its a great servo replacement for my old futaba 9551 which is over price.
Quality of this servo is good.
Its a standard low profile servo good for 1/10 touring car.
Value for money
Will buy it again if HK replenish the stock
