DAL "unbreakable" 5040 Props
Yes we finally have those so called "unbreakable" props.
They really take a pounding and come back for more. You literally bend them back and take off again.
These are insanely strong PC+glass plus fiber mix props that are flexible and have unmatched durably.
They however do generate less thrust compared to the HQ and Gemfan Props, but they survive all your dumb thumb mistakes.
