"The lastest customers please pay attention:For the brand XQ-POWER XQ-S40**D series 3 models XQ-S4013DXQ-S4016DXQ-S4020D have been Comprehensively optimized. For the convenience of using them under the normal voltage, our company readjust the original voltage range 6.0~7.2V to 4.8~6.0V. So now these 3 models Servos can work normally under the voltage range 4.8~6.0V. The speed has also been upped and the torque is constant. To bring customers the convinence, please fogive us."
which indicates that this is not a HV servo allthough it's specified
as a 6 to 7.2 V
After two flights the servant began to rotate on its axis as it had crushed the gear, I do not recommend. you will suffer in purchasingThe servo looks good, inside and outside, printed circuit nicely fixed with silicon rubber and so are the wires.
It is not a HV servo and that's bad because I bought it for that purpose, the XQ company doesn't file it under HV and it's specs are at 4.8 and 6V.
On 6V even under little stress it starts moving around it's position. Both specimens I bought do this. It centers well and it's resolution seems to be ok too.
HK please look in to this and remove the HV spec, other people might step in this trap too.
