Default Re: CA Models Osmose Delux ARC

I guess I should say that I first made templates for those formers out of 1/16" balsa, then cut the ply pieces. I lapped all joints with a skim of Hysol.

Happy with this, I looked at the adjusters next. The adjusters has some considerable play up and down. I studied this for a minute and decided it was due to the fuselage side flexing in and out when pressure was added to the adjuster. To "stiffen" this area, I created a light-ply CF stripped 1/2 former that ties the wood mount of the wing adjuster to the fuselage side and fuseage floor, then to each other. This single 1/2 former added AWESOME strength to this area!!! At this point the only play in the adjuster is between the clearance of the 4-40 adjuster screw and the adjuster cage. Not sure how to get that out, but I'm satisfied with the improvement. This is easy enough to add that I would suggest you guys check out your planes, and see if you detect fuselage side wall flexing in that area.
