F-104 Starfighter Project 1/16th scale


My next project will be a pusher prop F-104 Starfighter (no cheating on wing area).

1/16 th scale would bring the:

Wing Area to 110 sq in
Length: 41.0625 in
Wing Span: 16.4375 in

Flying weight goal: 17 oz
Wing Loading: 22.3 oz/sq ft

Stay tuned !

Matt,

Here's a link to my previous project.
I'll be using the same powerplant on the 104

Great control system, but what if...


I admired your F-16 control system, and posted my question there first. I'll try again here - what would happen if you abandoned moveable tail surfaces altogether, and went with all-moving wings? Increase AOA = climb, decrease AOA = dive, opposites for roll. This would move all weight to the center, allow really sturdy/simple tail (particularly as the F-104 is a T-tail).

I'm most interested in this as an aerodynamic point. For aircraft with small structural loads like models, why wouldn't this be a much more efficient system? I seem to remember an old slope-soarer that flew this way, was scary as all hell...

Hmmm. I'd try it, but I'm working up a Super Decathlon...

Iphan,

I remember that F16 - I was impressed.

Will this one be foam or balsa?

Best wishes - should be a fun challenge. Balsa construction?

If you end up with any free drawings?

NateDog,

Now I understand what you're talking about. Yes, I've thought about the same controls, having a totally fixed tail and moving using both wings as controls. I'll give it serious consideration. My only concern is the F-104 has anhedral, the wings are very close to the ground, I'm afraid they might rip off on landing, especially if I have to pivot them.

For now I think I'll stick with standard ailerons and elevator.

Matt and Thomas, it will be standard built up balsa like the F-16.

Dear Vintage1,

Like the F-16 I will post the .dxf file on my website after I'm finished. There's a link from the F-16 discussion mentioned previously.

Here's my progress so far for the F-104.

Cheers,

Le

Looks great. Is that balsa planking on a crutch-and-former?

I don't thing the small wing matters, as long as the rest is light.

It will just be a bit draggy with that relatively huge fuselage.

I reckon a DF would work in that with an extra air intake under the fuselage.

Plenty of exit diameter.

Should be spectacular in the air anyway.

Le, looks great! Can't wait to see how it works out on the scale wing area.
