Micro Linear Servo 1.5g

Finally there is an alternative to the Spektrum linear servos. Here comes HK with a 1.5g micro servo for only $5.99, which will be available as a right- and a left-servo version. It was announced only 2 weeks ago on RCGroups.com by manufacturer Assan. Right now there is only a 2-servo V-Tail version ($22) available at HK but the single servos are expected soon.

Unlike with the Spektrum model, the electronics of these new servos are on a seperate PCB. So it might be possible to make the servo even lighter by removing parts of the PCB on which the actual servomotor and pot are mounted. Depending on the ohm-rating of the pot it might also be possible to use a different (maybe lighter) controlling board.
