I've put together a handful of different kits from Moyustore and this one was the most challenging. Some of the bolts were too short and a few holes had to be drilled to fit as per the instructions. I had to modify the droopy wigs with extra support and some stabilizer bars from spare parts of other kits. The wing are magneticly fitted to the dragon torso. Any movement and the wings fall off, best to bolt these in place. The torso is also magneticly attached to the supplied stand. With wings in place, the model has a very forward center of gravity on the stand. Any movement and and everything tips forward in an uncontrolled manner.

It's a good kit but it could use some refining.

This is the largest kit I've built so far (the 2,000-piece dragon is waiting on my shelf), and it was a fairly smooth build. The only occasional difficulties were with the instructions - for example, there were a couple of places where the short/long arms of a bracket should have been indicated - and with the final body assembly. There are clever ways to lock the legs in position, which aren't in the instructions, and - perhaps the biggest issue - the main tail joint does not support the tail, and it sort of flops down 90-degrees. Which is fine if the wyvern is standing on its legs, but not so good when it's on the stand. I ended up soldering that joint to get the tail to stay in "flight position." The end results, though, are worth it.

Some of the nuts provided don’t fit on the screws they are suppose to go with. Nuts #13 are too big for screws #2. Therefor it is impossible to complete it without glue or welding. Very disappointing considering the amount I paid for the product.
