Building Uproar 40
I just got my Uproar 40 kit from tower Hobbies, Im Still getting the assorted stuff I need to build it. I was laying out the plans on my building board, im using 1" pink insulating foam sheets, and noticed that the sheet ive got is just a hair outside of flat, its about 1/8" cupped. Is that 1/8" going to cause me problems with building? My second question is got the general frame up how do I know where to use CA (thick, medium, thin) and how do I know where to use epoxy? This isnt specified in the construction manual and rather than screw up my first R/C kit I figured I'd ask. Thanks for the advice in advance.

RE: Building Uproar 40
The airframe will only be as true as the surface you build it on. I would suggest you get a balsa building board. It will last a lot longer than the foam.
Most of your construction will be done with CA. Use thin where parts are tight together. The thin will "wick" into the joint. Use medium where you need more time to get parts together or where gap filling is needed. You will use epoxy on the firewall, wing spar and mounting, and on the landing gear plate. Epoxy allows for some flexing and is desirable in these locations. The trade off is that it is heavy!

RE: Building Uproar 40
I know the airframe will only be as true as what I build it on, I used to build free flight rubber powered models from 24" span down to peanut scale with good results. The larger models I built weren't as sensitive as the peanuts to the absolute flatness of the board I used, Im just wondering wether this trend continues as the uproar is much larger than anything I've built prior to this.
