F104g 1:4 scale
 

Hello,

this is the second flight of my new 1:4 scale Starfighter.
Not yet painted, I'll paint it as soon as possible.
29 kg at take off, behotec 165, all wood.
I draw it myself using catia, all parts are laser-cut.

I hope that you like it!

Beautiful model and nicely flown, looks real!
Many congratulations. :-)

RE: F104g 1:4 scale
 

Very nice.

congratulations. Wood jets fly very nice.

Do you have details from building?

Best regards

Thank you,

in enclose some picture(sorry, poor quality)

Very nice Damiano...

I could only start something like that when I retire:D. Full time job and 4 kids;)

The landing gear is commercial or did you do it yourself? The plane seems very low on the ground.

Congratulations

Nuno

The gears are made by Behotec(very strong, the best), distance from ground is (about)in scale. My target are not to build a superscale but a "weekend model", I make about 10 flight per week and I want to reduce maintenance timing as much as possible.

Nice job, glad to see some one scratch building.Thanks for sharing:)

RE: F104g 1:4 scale
 

That thing is huge!

What do you transport it with?

Nice job. I wish I had the talent and the patience to do something like that.

Meesh, thank you.

I can cut my model in 9 parts: nose, front fuselage, central fuselage, rear fuselage with rudder, elevator, 2(little)wings, 2 wing tank.
In a little station wagon with 3 persons I transport it with all tools!

A very competent piece of work, building and flying. A man after my own heart, well done.

Congratulations On a Job well done. Looks to be very manageable on approach. :D Thanks for sharing

RE: F104g 1:4 scale
 

Damiano,

Now I know how you were able to get it out of your basement after it was built.

Thanks for explaining that!

Post pictures after it is painted please!

Bob

RE: F104g 1:4 scale
 

Truly amazing!! That has to be the boldest creation I've seen on RCU. Good job!

Thank you very much, I'm really surprised about you comments!!!

I've not yet decided what paint scheme I'll apply but, sure, italian scheme special paint!!!



Here you can find some other picture and the first flight video.

In a word FANTABULOUS!! Not a word but fitting for this plane! Awesome job my friend!!

RE: F104g 1:4 scale
 

Bravo!

RE: F104g 1:4 scale
 

Very nice, you should be very, VERY proud !!

RE: F104g 1:4 scale
 

Magnifico Damiano; Un'opera d'arte!!!!!!!!!!!!

RE: F104g 1:4 scale
 

Fantastic work and what a beautiful flight and landing!

hoping not asking too much, but would like to see details on how the fuselage splits in parts and how the parts are attached.

Also found interesting why square section main spars where used in the wings..and certainly look plenty strong!

RE: F104g 1:4 scale
 

Enrique,

To select the section of bar I calculate the force on wing @ 10g, I check what my aluminum supplier has and his material then I make some finite elements analysis to obtain @ 10g the maximum stress lower then yeld.

The used material is EN AW 6082 T6, Rp =250 Mpa and Rm =310 Mpa 20x15 mm thickness=1.3mm.
2 bars are little bit over dimensioned (max stress obtained in traction is about 190MPa), this is not the ideal section, but it is the best solution that I find from my alu supplier!

This kind of calculation was done before starting to engineers the model, the same methodology was used to calculate the gears support.


About the details of splitting, this evening I make some photos!

RE: F104g 1:4 scale
 

Thanks Damiano, and great model analysis .. also a good thing about beefing up the wing is making it plenty rigid for holding those big tip tanks without any oscillation.


looking forward for the pics!


all the best, Enrique.
