Yes...It would be just behind #2main bulkhead. If you look at the profile of the fusalage(without wing installed), the area I'm speaking of is above the biggest section of wing cut-out, which is just behind #2 main bulkhead...you'll see it, it is just in front of the canopy area. This is where they break thier backs, and if you look at one that's built already(or your really good at visuals from plans), you'll see there's not alot of anything there for structure. It's really OK, and it doesn't need any modifying, as with the Extra it does what it needs. You just might want to be aware if your altering what's there. Have fun.
