Review by: Barry
Great little lightweight wing servoI have these servos in 2 gliders already and go these for an aerotow Jantar 2B. I've used other bluebird servos in numerous other models without issue. Really with their power and centering seems to be very good

Powerful little servoAs advertised. Fast shipping.
Installed in 3.8M F5J sailplane. They operate smoothly with accurate centering... What more can you ask for... longevity... that remains to be seen... So far so good👍🤓
