Countryboy,
Good pics, they are helpful, thanks. My Roo has the foam herex formers that are very weak compared to the balsa in yours. I guess ripping them out if needed won't matter in the big picture but, I will start with augering out the rear former opening and if it won't fit then I'll R/R the front one and continue. BTW I also need to glass the seam at the front of the fuse inboard of the root attachment point for the wing. I hear it can separate and that could be catastrophic in flight.

Thanks again for all of your help, I've enjoyed the "back 'n forth" I've had with fellow builders and pilots.
