Volantex RC P7610505 Propeller Set for 761-1 P-51D

Volantex Mini Mustang P-51D RC Airplane Spare Part Propeller Set

The propeller protector has been improved. It will only separate from the airplane when it hits something in the state of full throttle.

When you turn throttle into the middle position or not more than it (half-throttle), the propeller will only stop rotating if it impact something instead of separating from the airplane, that reduces the probability of loss.
