I have been running Spek receivers with Savox (Orion) servos for almost two years (in nitro cars) and not had those issues. I have run Spektrum radios and receivers for about 4 years, but not with the Orion servos. Prior to the Orion servos I have used every Spek receiver except the SR3100 and 3300. I have run Nimh, Lipo (regulated) and now Life (unregulated). Since going to the Orion servos the only receiver I have used is the SR3520 receiver.
