NXB-Gianfranco Collado Verified Owner Saturday, Mar 15 2025 (7 months ago) Spektrum RC A7090 Brushless Low Profile Metal Gear Servo (High Voltage) Perfect!
Good size and will last forever! If you need a retract servo this is the one! Gary Meyer Friday, Aug 25 2023 (about 2 years ago) Spektrum RC A7090 Brushless Low Profile Metal Gear Servo (High Voltage) I purchased 2 of these servos as I needed a low profile servo for my float plane.
These are really poor quality.
They chatter up and down and they have a hard time finding center. I just hope they don’t quit in flight.
They are mounted on my plane so I will keep them. 0 of 1 customers found this review helpful. View all reviews
