I recently purchased the WS-15 Turbofan Engine from my friends at enginediy. The model came packed in a compact cardboard box and arrived in good order. On opening the box, you see two QR codes. One of them points to the assembly instructions and the other to a video of one of these being assembled. Looking at the Internet, you will discover another video by KOTA also assembling this model. NOTE: You need to watch the videos carefully many times to understand how the model goes together. There is no parts list for this model, which is a pity. As I started to assemble the model, I got stuck at step 1, because there was a duplicate of one part and another missing part.
I contacted my friends at enginediy and they sent me the replacement part quickly. Thank you! The second attempt of assembly progressed well with the new part. Several times during the assembly process, I had to tear down what I had done, because I had installed a component backwards. I actually don't mind this, because it is all part of the learning process, making the model a real challenge to build. I have to say that the instructions could be clearer and a components list would be invaluable. It appears that the components are printed with a 3D printer - amazing! I had a real sense of achievement when I clicked the power switch the first time, the model sprang into lifeand functioned as expected.
If you like a challenge and like to build engine models, I thoroughly recommend this model. I owe a big thank you to enginediy for their excellent after-sales service. Recommended.
