I'm going to guess you are correct on the total final weight as the weight they gave can simply NOT include the engine and radio gear. That is a very poor way to advertise a plane and the first I've seen done like this.
As for the spinner, yes, most kits suggest a size and it's usually geared to blend into the cowl. But trainers don't really have a 'cowl' so just use your best judgement. It's probably going to look best with about a 2" or 2 1/2" spinner. Or, you could use one of the metal 'safety spinners' offered by Great Planes or Harry Higley. These all come pretty much in the same size only depending on the thread of you engine prop shaft. They are fool proof and crash proof and easy to install. With the safety spinners or hubs, you should use the matching locking nut or 'prop nut' which gives you a double lock on your prop.
Enjoy your plane!

The manual that came with it was next to useless. I've never been a modelersoI'm going very slowly on the build. I found links on tower to manuals for similar trainers which helped me figure out what I was seeing in the Chinese manual I got. That has helped a lot. I'm ready to start installing the Rx/servos and connecting the linkages. I hope that goes well.</span></span>
