I recently ordered a pair of these servos plus 4 other KST servos and some bits and pieces from Hyperflight as part of a refurbishment of an old slope soarer. There was a minor problem with the bits and pieces, but that was very quickly remedied after a phone call to Neil. Excellent servos, and excellent service, as always, from Hyperflight
Installed these in an f3b glider on ailerons and they are not centering well. Mini x10s are fine. I will have to do some additional testing, I will pull servos and test centering.
Havent started mounting yet. Service is excellent, but paying by Paypal vas expensive.
First time used these servos , cantering is good . I am waiting for the weather for test
This KST servo has more backlash than the MKS 6100 servo, but it works well under all voltages. If you prefer no backlash, it's better to use the MKS.
Bravely fitted these as Flap servos in an El Nino. A 10mm servo would have been a very tight fit in the thin wing. Fits perfectly in the same frames as the rest of the X8 range. Landed several times today and threw the glider around in breezy conditions. Behaved perfectly on 7.5V.
