I've looked at about 4 or 5 of these kits before. But everything is in "chenglish", I'm never too sure what is or isn't included. A big thing for me is all the sellers sell all manner of blatent copies of things -they are not model kit suppliers. I've fancied one of the kits for a while -but the seller feedback is just way too low from the suppliers for me to buy. I ordered stuff from China before, I think everything either went back or was just refunded through ebay anyway.
To be honest though -I looked at these kits for a whle and I thought for the hassle of ording from dubious supliers, I thought there was enough detail in the pics just to scale up with a ruler and A4/A3 paper and make my own if I wished? If you want an exact fit-to-gether build with exact instructions, fittings -I think it's wrong to assume you'll get that from these suppliers just from the quality of the advert! I've always held onto my £30'odd -thought it was spent better elsewhere.
