The wings are just pinned on for the picture. It will have a medium amount of dihedral.

Looking great AK...doesn't look like she has very much dihedral.  But the angles of the pictures don't really show dihedral!!  I can't seem to get my builds going or completed like y'all are doing lately.  Your builds are so clean and fresh in craftsmanship and then you cover those bones with great tissue work.  I'm envious!  Keep us the great work!

Moving right along on this. Wing mount is 2
wood dowels thru the fuselage and into the first two ribs.

Yep...that's the sound!!! Grin Wink Cool
Love the F-104's amazing aircraft.  You're one lucky guy to have flown all those jets!!  I've yet to figure out how to make a rubber powered F-104G.  A 27" span F-104 would have a very long fuselage.  I have seen a paper F-104 with a rubber powered ducted fan that actually flew very well  outside. rubber powered F-104G

Our 104s at Luke were actually built by the Germans to be flown in the US in USAF markings. We had two squadrons for initial training for students coming out of USAF pilot training. We also had a separate Fighter Weapons School that used the same aircraft. I started out as an instructor for the initial students and then joined the weapons school as an instructor.

In the Right Stuff movie, the 104  used for the ground scenes was one of our Luke aircraft, tail # 269, flew it many times.

The only thing missing from that video is the 104 howl... I remember several F-104G's from Luke AFB (I think they were German Airforce but in U.S.A.F. marking) and NASA's F-104G's at several airshows I went to.  I just remember the  howl of the engine (J-79's I believe)  very destinct sounds.  They used to fly through McCellan AFB on maneuvers. I used to photograph outside the base.  I agree, fond memories!

Brings back some great memories! We didn't aerobrake the 104 after landing. Raising the nose actually decreased drag. Instead, the drag chute was typically used.

Wow!  I need to up my surface detail game after seeing that model.  Love the flight, especially the aerobrake on landing...

AK, the Spartan Bomber build is coming along nicely - this is my second favorite Jimmy Allen plane (after the Bluebird Racer).

Nice, Andy!  Was wondering how a vac'd canopy might work...maybe even to include that small bit of "turtle decking," from a weight-saving point of view?  Just an idea....

Neal


Hard to say. Depends on how much of that upper deck is going to be molded and the thickness of the plastic. As is, the front windscreen probably won't need to be molded.

Off and running! Fuselage box is 3/32", nose stringers 1/16".

Turtledeck is changed from the plan. I made upper formers to support the 1/8" sheet top and then hollowed out the formers. The plan method looked like nothing but headaches.

Wing support is complicated by the idea of a slot to allow changes in the Cg. Don't think I'll do that.

Starting the wing today. It too is a bit different. The rear "spar" seems to be a stringer-like stick that passes through the side of each rib (a hole is drilled for that). Not sure what that adds to the strength of the wing. Probably will use something more traditional.

Alright AK...another great choice and I can hardly wait to see how you bring this one together!  Getting the popcorn and soda (or should I say Ovaltine!) to follow this build.  I remember Captain Midnight but I believe it was on black and white TV Click Here for me... Loved his Douglas 558-2 Skyrocket Grin Cheesy Smiley

This is a very cool model. I always sub 3/32 for 1/16 as like you, smaller stuff seems too fragile. Pick the lightest stuff you can get and build to plan. Once the frame is done and all nice and straight, then do a little adding if need be. I'm sure there are several models out there flying really well and yours will too.
