Any of the "white/yellow" glues are okay for what you are using them for. If you run a light bead on the top edge of the rib then carefully position the top sheeting piece over the ribs, then pin them in place to the bulsa sheet is held firmly down on each rib.

Do not get carried away with this glue, it can ad alot of weight to an airplane. The bottom ribs can be glued into place using medium CA, sparingly. I have also used medium and thick CA in the manner described above for the resin glue. If the CA is kept in a refrigerator, it will last alot longer, and also cures more slowly when it is cold. The advantage to using the resin glue is that it give you alot of work time and cleans up easily with water and paper towel. The advantage of the cold, medium or thick CA is that it dries much quicker, if you have steady hands, and can get the part in the exact location the first time.

I have built one of your airplanes from the box, ready to fly in less than 40 hours. It is a great, simple kit, with good instructions. I also built four 4*60's. I don't think I used any resin glue in any of them, just CA and 30 minute epoxy. I would never have been able to build so fast If I had to wait on the resin glue to dry on the wings and fuselage. None of the planes had any problems with glue joints and all came out very light, with great flight tendencies.

If you have any questions or other problems feel free to send me a PM and I'll try to get right back to you.
