KST X12-508 Servo

Great service as usual from Neil, and super quick response to my telephone query. The servos? I chose them because they are immune to Frskyís telemetry signal, so therefore donít jitter due to the close proximity of the rx antennae in a glider nose. Very good servos for rud/elev surfaces - very powerful, excellent centering, and very fast. A happy bunny am I.

Excellent replacement Servos

Being a fairly regular customer of Hyperflight I needed to replace the cheap and nasty Tower Pro servos in my RC Factory Edge 540 V3. Having bought KST servos from Hyperflight before, these KST X12-508's are superb and have transformed the "Edge 540" to another level. Fast and reliable, no jittering anymore and they respond beautifully to my Jeti Assist Rx. Great service from Neil and his staff as usual. Highly recommended.
