Comments: I don't like this servo very much. Mine are oldtimers - beginning of the nineties! - and came as I used Graupner C505, Sanwa SM631 and Robbe RS 100. I noticed they were a bit more powerful and perhaps speedy - read what was my comparison basis... - but I found they were noisy, gritty like there was sand inside the gears, and I haven't the same building quality feeling. So, decent servos, but they don't have any interest in front of nowadays chinese high-entry level (!) like towerpro 996, IMHO.
