Folding propellers are a new development in the world of copters and are vapidly increasing in popularity with their ease of storage. They act exactly as the standard propellers whilst in flight, but when it come to storage, you simply fold the propellers back to decrease risk of damage. This is a small instruction guide to help with the construction of these propellers.

Step 1: The first step is simple enough; place the white washers in the indentations in the propeller adapters as indicated in the picture below.
Step 2: The next step is to attach one propeller to the propeller adapters. For this task, you need to use one of the two longer screws that are supplied in the folding propeller pack. At this stage it is essential to get the correct propeller adapter in the correct position. With help from the picture below, you can see that the top propeller adapter must be the one with the two larger holes.You then simply place the propeller over the suitable hole on the propeller adapter. You then flip the top propeller adapter over so that the washer is in contact with the propeller, and screw in the screw. It is advisable to attach this propeller loosely ( and so do not tighten screw) so that there is enough manoeuvrability to attach the other propeller, as shown in the third picture.
Step 3: Now you simply attach the other propeller which should be made easier if the other propeller is not yet tightly secured. Once both propellers are lightly attached, you can fasten the screws in tightly. After this is done, you have the finished product, as shown in the picture below.

In this pack, you are supplied with two sets, and so you carry out this same procedure for the other set, to get the product shown below.
Extra Step: In order to use them you will obviously need to attach the folding propellers to your motors. The propeller holder will fit any motor that has 12mm mounting holes. These are attached just like any other direct mount propeller by screwing two screws into the countersunk holes on the prop holder as shown in the picture below. . Sometimes due to the tight constraints you may need to use some bolt head screws to attach them to your motor as some screws have heads that are too large.

Hello folks, I am quite new here in the forum, I have been reading for quite some time, now I have registered and I have some questions about the propellers, which - according to my understanding - are THE essential components of the mechanics as they convert all commands of the electronic into motion.
Before I owned my second-hand SPARK, I had a drone of an other brand, also with foldable props. There it was said that the blades of the props had to be able to move very smoothly to avoid "jello" in the video recordings. So I optimized the props, with the corresponding improvement of the image quality.
Now with the SPARK, the blades of the props are quite stiff (they do not move easily in their axle bearing) - but I have not noticed any disadvantages in the video recordings.
Therefore my question:
- Is it ok if the propeller blades are not moving particularly smooth? (The motor axles are running perfect!)
The props of the other drone were quite damageable. ?
Despite of some landings in high grass, where my SPARK has proven itself as a kind of lawnmower ?, the leading edges of the props are still undamaged - so my impression when running my fingertips over them.
- Are the props ok as long as I don't see or feel any damage?
- How often should you change the props?
(I still use the same props that I got from the pre-owner - the spare props are red and I do not think, they are high-quality spare parts.)
More questions:
- If I buy replacement props, how do I tell the difference between "original DJI" and replicas, which may be of much lower quality and affect engine performance and flight time?
- At AliExpress I saw some offers with an explicit notice: "These propellers can only be used together with the Propeller Cage. Please do not use these propellers without the propeller cage, or else the flight time and maximum thrust will be reduced." (The technical background of this statement is difficult to understand ... )
Does this statement make any sense at all?
DJI can not deliver right now ... Anbee is not available on German Amazon and MAS will send to Germany - for very high shipping costs - which is probably justified.
Finally I found out who made the spare props that came with the drone: They were made by CAMKIX.
I read some really bad reviews on Amazon like "
no stable hovering anymore", "
drone seems to fall into "holes in the air" when ascending", "
no precise flight" and so on ...
As I own them now, I testet them today and I was very astonished: besides a slightly more annoying flight noise (just the opposite of what is said about MASTER AIR SCREW) they seemed to be totally ok. The SPARK behaved exactly like I flew with the original props.
So I will use them as reserve props and keep watching the German market. I will be notified if DJI can deliver again.
