Review by: Mr Michael L Dwyer
I haven't got to use these servos yet. I bought 2 of then and one died after 6 cycles on the tester didn't get anyway near the plane.
Waiting for a replacement to arrive.
They look very good, at least it had the decentness to die on the table.
Buying from the opposite side of the planet is a bummer when things don't go to plan.

Excellent service and communication - 10 days order-to-door from UK to Australia. Have only tested one so far, but looks the goods and the price is right. Thank you!

Early days yet, thanks to the plague, but the performance so far is excellent for such a compact, moderately priced servo. The service from Hyperflight excellent as ever.

Four servos delivered, without fuss, on time and whilst not yet fitted in to model I am very pleased with them. Packaging exceptional! I have no reason to believe the servos will perform to the same standard.

Used Blue Bird servos in my F3K and have been more than happy with them so decided to use these in my newly purchased Osprey F5J. They behave implacably.
