Shit. I totally missed the mark on the original question.
As for the quality of the kit as a whole, I really couldn’t tell you properly. The box casing IS good, that much I know.
•Motor - Blue ChiHai. Allegedly has more torque than… um… a motor with less torque? I have heard that they’re relatively decent though
•Piston + head - they look like FB pieces to me. I know one particular forum member isn’t a huge fan of FB but YMMV
•Gears - look like a generic pressed Chinesium set
•Other bits - all look pretty generic as well
To me, it really hinges on how much effort the tech puts into ensuring it runs correctly. I could cram all of those bits into the box in about 5 minutes but it might not even run for half that long once done. If it’s assembled with care it should go for quite a while without issue.
My suggestion would be check all available options before committing. My 2 cents…
