Happy Fourth right back at you, Bobby.
I have been lurking in the background since you started this thread ..... mostly to get a feel for the kits from this company - quality, fit and ease of assembly. Looks like they are a good kit line.
If you are bolting balsa (the stab) to lite ply or a/c ply you might be creating an abnormal wear (both abrasive and crush) point. Just thinking out loud here - not saying its good or bad. I have a removable stab designed into my 1/3 scale Nieuport 11 and added a 1/32" a/c ply layer on the top and bottom of the stab where it mounts to the fuselage. It has proven to be sound over the 3 years I have been flying it.
I just flew my first multi-engine bomber last month ....... 110" PB4Y1 (Navy version of the B-24). I sure do like the sound when it flies by - TOO COOL!
I had been thinking about the 84" stick, but might go for a twin now
I am enjoying your build and looking forward to hearing your first engines run-up and seeing the maiden.
Cheers, Art
