I am new to the hobby and I am getting tired of flying my trainer. I do not know much at all about r/c plane construction, so in your responses, be as clear as possible.

I bought the Extra 300S kit from nitroplanes.com. I am now realizing that the savings are not worth the frustration of assembling this crappy kit. The directions say I need to glue the two wing halves together with epoxy glue. There is a 1" hole in the center of each wing, but no wing tube in the kit. Is a wing tube required for this kit? Should I find a wing tube to fit and insert it into these holes before i glue the wings together?

Also, there is a smaller hole near the rear of each wing. I've seen some other planes that will have a small wooden dowel that is inserted here, but the two dowels that are included with this kit are too big for the holes. The directions don't even mention the two wooden dowels anywhere in the kit build, so i have no idea what they are supposed to be used for. I am hoping I catch someone on here who has built this particular kit before. I will upload pictures and get more details when i get back from class . Thanks for any help, I am just clueless as to how to assemble this thing.
