If it’s the same as the one I bought you’re better off sending it back.
I wish I had.
Apparently it’s a rip off design, there’s a bit of discussion about it on one of the American model boat websites.
There’s supposed to be some 3D printed parts to complete the hull that aren’t included. One of the hull frames is 30mm or so wider than the others. None of the locating lugs are there on the superstructure but the slots for them to go in are there. A lot of other parts are missing or useless. The slots for the hull frames/keel are very loose on mine, it’ll need packing at least a mm thick. The outer layer on the ply comes off very easily too.
They will email you the instructions if you ask, but any other support is non existant and I did try to get the missing bits but they played dumb. Only time I’ve left negative feedback on eBay.
Build able but?
Sorry to spoil it for you, but that’s my experience.
