Volantex P51D Prop Saver Base Black Shaft Part for 400mm RC Plane
Prevent Propeller Shaft Bending, Stop Flight Disconnections, and Upgrade to Reinforced Shaft Mount Security
Worn, cracked, or loose prop saver shaft bases on your VolantexRC P-51D Mustang 400mm RC Airplane cause propellers to spin off mid-flight, vibrate erratically, or fail to detach properly during unexpected nose-down landings. Over time, plastic fatigue on older shaft bases compromises their friction grip, leading to sudden power loss, dangerous propeller play, and potential gearbox or motor shaft damage upon impact. Attempting to glue broken plastic adapters or using non-reinforced fittings disrupts flight stability and risks damaging your warbird's drivetrain. This official updated Volantex P51D Prop Saver Base (Black Version) completely resolves propeller mounting and detachment issues. Re-engineered with high-impact composite materials, it delivers a secure friction hold during high-speed throttle runs while guaranteeing clean pop-off protection during impacts. Ships worldwide.
Product Highlights
Updated Reinforced Shaft Geometry: Upgraded polymer molding provides tighter shaft clamping to prevent rotational slipping during high-throttle scale aerobatics.
Impact-Absorbing Prop Saver Mechanism: Protects the motor output shaft and internal gearbox gears by allowing the propeller to pop off safely upon ground strike.
Precision Factory Fit: Engineered specifically for the VolantexRC P-51D Mustang 400mm drive pin layout for a true plug-and-play installation.
High-Durable Black Polymer: Molded from tough, fatigue-resistant black composite that endures repeated pop-off detachments without cracking.
Compatibility
For the VolantexRC P-51D Mustang 400mm 4CH EPP RC Airplane only. Full model page (specs & photos):
Essential for Older Models (White Adapter Version): If your plane is an older model that originally came with a white adapter base, please note that older white adapters are discontinued. You MUST install this new black adapter base to use any newly purchased replacement propellers.
Standard Replacement for New Models: If your plane already uses the black adapter base, this is a direct 1:1 original replacement part.
What’s in the Box
1 x Volantex P51D Prop Saver Base
Install Tips
Removing Faulty Shaft Base: Firmly slide the damaged or cracked prop saver base off the motor gearbox pin; inspect the steel shaft pin and clear away any remaining plastic debris.
Aligning Updated Base: Orient the internal keyway slot of the new black prop saver base with the flat notch on the motor output pin, then press straight back until fully seated.
Snapping Propeller into Place: Align your matching propeller hub over the dual retention tabs of the shaft base and push firmly until it clicks into position.
Pre-Flight Spin Inspection: Gently flick the propeller by hand to check for straight rotation, then perform a low-throttle power test to verify zero vibration before takeoff.
