RE: Who makes this Edge 540?
Spent some time at a friend's shop last night - we determined the wing panel was fine, but the fuse side was slightly bowed inward creating the gap at the wing root.
ended up adding a little balsa to the root and sanding down for a flush fit. We also talked about modding the wing so that the wing bolt will screw in through the fuse instead of through the hardpoint out in the wing. We're also not 100% sure that we're going to use the supplied incidence adjusters.
As soon as I buy a battery for his incidence meter, we're going to get moving on that. In the meantime, I'm going to start installing radio gear.
I test fit a DuBro 14oz tank and it should fit with only slight trimming of one former.
I will post some pics later.
