Modified the wing to take captive nuts just before the small metal rod and put nylon bolts/washers from the inside of the fuselage. I still have a slight gap at the trailing edge, I think the metal wing tube is a little big and might sand it down.

Has anyone flown with the wings fastened in this way or do you suggest glue?

I've run the engine up with an 11 x 7 APC pusher. It sounds a little noisey close up and we have a restricted of 80db at our club. I see a lot of people talk of Zinger props, will a 11 x 10 or 12 x 6 give me a quieter aircraft?

Hi
The wings will be fine built the way you have done It , the tail booms tend to pull the wing away from the Fuzz when tightened up sometimes
the front bolts will hold It together nicely, It is not meant to be glued Together .
OS 50 turns the 11*7 prop at 13300 on the ground and runs at 96 to 100 Decibels , so you may have problems with the Noise factor
I have done all I can to get It lower but to no avail , speed sits around the 150 to 170 K,s so It Is not a high speed machine Unless you put a turbine on It going By past posts
Before you assemble it check to see how far the alum spar goes Ito the wing , you do not want It to go further Into one wing more than the other , which might present a problem if One end is not supported properly by the wing ribs .
just my observations
