Review by: DavidBlue Bird BMS-125WV Servo
I had two '105' old versions fail when overstressed trying to open jammed undercarriage doors on my SHK. My carelessness. Nevertheless the new ones work fine and appear better overall.
Review by: NikolaGREAT!!!
Got them in my F5J plane (Crozilla) and works perfect now after 25 hours of flight.
Review by: Gary BlakeGreat servo but watch out
If you invert your power source you'll not just damage these you will fry them as they have no protection. I just lost 2... ;-( Own fault I know.

update on previous review fitted in flaps no response after landing smoke coming from servo and fitted new servos and worked great servo problem i think or just unlucky
Review by: Pieter
The servo is nice but has some play, the mks DS6100 does not have that so I go for the mks.
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!

Review by: Ian W
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.

These servos are accurate and good value for money.
Review by: RonG
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.
