I tested mine yesterday. Performance wise I cannot see any difference. If you get along well with child proof caps then you will have no problems mounting and taking them off.
Aircraft owners have always paid for AD's that were mandatory to the airworthiness of the aircraft. In laymen's terms, if an recall came out for your aircraft, it could be grounded until you paid & had the repairs done & had your maintenance logs updated. I don't see this would be any different.
Seems a waste to not use the two sets of blades we already paid for as long as you use the prop locks they should be ok. Are there any issues with the DJI proplocks?
