The wing has two ply dihedral braces. Rusty/Chuck did these pose any issue in the production of the wing tunnel for the pipe?
Yes they had to be cleared..I was concerned about this and tried to take away minimal material..
Chuck,
I received the piece of Kevlar - much appreciated! A piece will be used on the fuse header tunnel. BTW, my kit shows a couple of pieces of 3 mm (1/8") balsa used as a floor for the fuel tank under which are the two bottom nose blocks (MK style) where the header sits. Did you feel any need to substitute that balsa for ply? Will the Kevlar be sufficient to keep the heat at bay?
Also, did you run into any issues with the installation of the RE YS? Does the cowl enclose the engine? Did you use a regular fuse top header? I'm considering the same setup.
My kit was a ModelTech ARC so the fuse was built..If I remember correctly I think my fuel tank floor is ply...I can't look at it to confirm because it's covered by the Kevlar pipe tunnel now so I can't see it..I'm pretty sure it's ply though..I remember I added some more ply in that area because I changed it over to fixed gear..It's possible I could be confused weather the whole tank floor is ply or just what I added??
I set mine up for a YS-61 LS mounted inverted..The head will protrude through the bottom of the cowling otherwise It's enclosed nicely...I did use a 1.5" fuse top header..I'm probably going to install a OS 61 RF instead so I'll have to re-work the cowl a little to re-locate the needle valve hole and shorten it a little but not a big deal at all...
Good Luck and enjoy!!
Chuck
