I recently found a set of aircraft aluminum prop adapters for the inspire 1. These adapters came with a set of 13.5 inch CF props. Total for the 4 props and set of 4 adapters was 67.87 shipped. I know that DJi does not recommend any other type of props with adapters for the I1. I choose to try these out due to the size of the prop. I have a need to use 13.5 inch CF props. I need to be able to deploy quick, have a set of CF props available, (for responsiveness of the I1) get in for the pictures and video and get the heck out quick and fast. 13.5 Inch props allow the i1 to be a little bit faster. I got 50.5 MPH in ATTI mode with a 7 MPH tail wind. Any way here are the pictures of the props with adapters and the place you can get them. I thought they were a good buy so I figure I would share. I did post this on FaceBook, however due to a certain admin, who is a crook in my book, my post was deleted and I was banned from the page. I guess sharing what I found was not allowed on a open forum. Any who…here is where you can get them if you want them. After flying with them, and putting them through they paces, I will be getting another set.

I really put it through the paces with these and I could NOT get them to come off. I even loosened the front 2 props and started up the i1 to see if they would tighten the adapters. They did and If flew perfect. I am a true believer that DJI made a mistake in the 1st set of props where as the hub stopped the prop from going all the way down. If they would have drilled a hole in top of the metal hub they would have not had a problem with the props flying off. Thus no prop lock would be needed.
