It appears the new mounting plates and props have an approximate lifespan of 200 flights. These appear to be consumables. So, either factor in the cost associated with the convenience of quick release or.... continue flying with the standard 13/45 props and prop locks. The problem of course is all supply of standard props will dry up (assuming it ever started) So, just be aware you will have to change out your props and locking mechanisms at regular intervals as the cams will wear on them. Not a problem, but just a heads up for people who might think they are a fit and forget addition.
