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
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.I bought 2 nice working pcs. My project is not finished yet, so no flying data, but it looks like a rigid and quality servo. The dimension and the weight are pretty exact, this a short servo!
Bellow some data on 6Volts:
Max/stall current 2,2A
static load (with acceptable arm movement)
5kg -> 1,2A
6kg -> 1,5A
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
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.
