Am I missing prop washers
-
Tomorrow I was hoping to take the Sentinel out for its first flight, I was following the quick start video that made a strong emphasis on washers on each side of the prob.
On the underside of the drone a zip lock bag was there with a set of screws, (I'm not sure what these are for but there are four of each)
On closer inspection I noticed there was a washer present on the motor however this doesn't seem to fit snuggly in the prop.
I have included a photo of the parts (making a point of being overly cautious here)
Am I missing washers if so could you let me know where I can source some, if not can you instruct me on the process?

@A-Evans the zip-lock bag has optional nuts if you wanted to mount the propellers using them instead of the conical nuts. You can use any of them.
The nylocks would be the first column to the left of the prop. They have the white nylon inside the nuts that prevent the nut from coming off. You will use a wrench or a socket to tighten these.
The second column of nuts furthest from the prop are non-locking nuts. No nylon here.
The conical nut, on the right side of the propeller, is another way to mount the propeller. No nylon here either. You will need some kind of rod to go through the hole to tighten down the nut.
You can use any of them.The washer, all the way to the left will sit on-top of the propeller to spread the load out evenly on the propeller.
To answer your question about the insert washer for the prop, what color are your motors?
If they're blue then the propellers would come with a pack of inserts, usually on the prop bag, that have different fittings that will sit inside the prop itself. Choose the one that fits the shaft snugly. We would highly suggest that once you find the insert that fits well, apply some glue to the insert and put it into the prop. This'll prevent the insert from getting lost or getting stuck on the motor shaft.
If your motors are black, then no insert is needed. The shaft diameter was changed to allow the prop to fit without needing to use the insert. -
@Adrian-Hidalgo thank you for this thorough answer, really useful we went with the conical nuts initially i through we had screwed them on and as we tested take off one of them came of along with a prop, no damage just couldn't find it anywhere. Went with the other nuts and managed to get a few seconds of flight before the weather turned down.
Practice and experience will be required, I suspect we may need additional props/screws do you have links to where we may obtain these?

@A-Evans You're welcome, glad I could be of assistance. You do have to tighten the nuts well, but not white knuckle tight. You will feel it tighten and then give it an extra little after that.
We have been trying to source any of the nuts but they are all out-of-stock. You can check any hobby store or Amazon. If you're trying to get the lock nuts, look for the aluminium ones. There's a lot of steel ones available. You're looking for M6's
