E-flite 9.75x7.5 Propeller (EFLP97575F): Genuine Replacement for Radian Pro RC Glider

You notice it right away on launch — the Radian Pro labors skyward instead of cutting clean lines. A slightly bent blade or hairline crack in your old propeller introduces vibration that wastes battery power and dulls the glider’s normally effortless climb. Every minute spent nursing an unbalanced prop is a minute lost from soaring, and the constant worry about a mid-air failure gnaws at the back of your mind.

Replace that worn part with the exact factory-spec E-flite 9.75x7.5 propeller, coded EFLP97575F, and the difference is immediate. The precisely matched diameter and pitch restore the smooth, quiet thrust envelope your Radian Pro was designed around. The climb becomes linear and efficient again, letting you reach altitude faster with less throttle, so you can focus on reading the air and hunting thermals.

Installation is matter-of-fact — just detach the old hub-mounted prop and secure this genuine replacement in its place. Because it’s molded to E-flite’s original tooling, the balance is already near-perfect right out of the package, which minimizes the fine-tuning you’ll need at the field. A quick spin-up tells you everything: the motor hums smoothly, the airframe settles into its natural climb attitude, and that nagging vibration is gone.

Flying a sophisticated sailplane like the Radian Pro comes down to trusting your gear. With the correct propeller back on the nose, you regain the confidence to range farther and fly longer, knowing the power system is doing exactly what it should — quietly and without drama.
