PTK7308
Manufactured in China
Looking for the perfect blend of performance, precision, and value?
The PTK 7308-MG-D delivers exactly that. Matching the dimensions of the popular KST X08 and offering very similar specs, this servo comes in at around half the price – making it a smart upgrade for any budget-conscious pilot.
Inside, you’ll find a high-quality coreless motor, dual ball bearings, and robust stainless steel gears, all securely housed in a CNC-machined aluminium case. The result? Incredibly smooth operation with virtually zero free play – ideal for high-precision flight control.
One standout feature is its wide rotation range – up to 180° from a 500–2500 µs pulse width – giving you greater flexibility when designing control linkages and achieving optimal mechanical advantage.
The 15T-4 output spline ensures full compatibility with KST X06, KST X08, and CHA DS06 servo accessories
