I love your nickname, muffinman. :-) Now I'll try to answer your questions........

World Models manuals are not the most informative for new ARF builders, but after you assemble a few, you'll notice that almost all ARF's go together identically. Just post questions in this thread as you go along....most modelers are very helpful.

Regarding joining your wing, use 30 minute epoxy, not 5 minute as it cures to quickly. Use a low adhesive masking tape and apply it to both sides of the wing a few layers wide close to the root. This will keep the covering clean while you work with the epoxy. Check you joiner and rib alignment prior to applying epoxy. Coat both rib roots completely and make sure you get plenty of epoxy in both joiner openings. After you are satisfiled with the joint, wrap the entire seam with tape. You can remove all the tape after the epoxy sets but is not cured. It will still be flexible and you'll be left with a clean solid joint.

World Models factory hardware is better than most...I recommend you use what comes with the kit.

A Sullivan or Dubro tank will work out fine but I've used the supplied WM tanks successfully. Consider replacing the stopper if you do. I like using brass tubes for tanks. Make sure you clean up any flash from cutting the tubes or you'll have trouble with fuel tubing cuts.

In a Cub a 4-stroke engine is more realistic but either the TT .46 or Magnum 4-strke woud be fine. TT makes a very nice .54 4-stroke also. Good luck.
