Thanks ED i'll have my "wing man" look into that he's moving this weekend so hopfully we can find the drawings.
I'm happy to report this morn that the fiberglass mod really did the trick to add stiffness to the fuse. i may add one more piece in the gear door area of the bottom fuse belly ,more on that as i sort out the retracts.
staring the fan mounting set up then on to the ducts.
hoping "Sky World" is following this and can just add some of these mods to there kit.
