With an integral heat-sink, these servos are designed for the demands of competition racing, keeping the motor cool even when the outside temperature is hot and the servo is being overused. With a heavy duty rubber-sealed waterproof case and high-strength horn set, this servo is perfect for high-performance R/C car applications. And the output splines are compatible with aftermarket 25 tooth Futaba horns.
The servo will automatically learn the user's transmitter pulse timings and lock into the signal every time. The servo also includes a signal buffer in the CPU with fail-safe functionality. The motor is wound with 2PEW thin coated wire for better electrical conductivity and is able to withstand high temperature without degradation.
The servo comes with an accessory package and the universal JR/Hitec "S" Connector which is physically and electrically compatible with all major receiver brands sold worldwide.

Is HK over-stating the specs for these servos ? I see on servodatabase (****): 4.8V: 82.0 oz-in (5.9 kg-cm) 6.0V: 112.0 oz-in (8.1 kg-cm) And for the model 825DMG HS the difference in torque specs is even bigger. So.. who is wrong ?

You don't need external BEC. All you need is a CAPACITOR on the Rx.

Ce servo est INUTILISABLE......quand on actionne normalement la commande dans un sens puis dans l'autre, le servo reagit normalement. Mais quand qu'on stoppe la commande, le servo continue de fonctionner d'un sens l'autre, d'une butee vers l'autre sans s'arreter.....

ATTENTION
These high performance servos are very strong and have a coreless high torque motor that requires a STRONG power source. Many ESCs inbuilt BEC cannot handle such current, and will shut down the Rx.
We advise customers to use an external UBEC when using this servo.
