Looks great, impressive build!

Hi Ragtop,

Thanks for your nice word. Challenging, but no complain, I love building and balsa smell :-)),

What amazes me, Javad, is how little previous design and drawing work you are needing for creating your Phantom. Or at least that seems!

Just working from enlarged 3 view drawings direct on the building board!

Best luck with the model.

Hello Jesus,

Yes, and no :-)),

Yes, as it took about 30 minute to print out a scaled up copy. A guy in a printing shop, using AutoCad, scaled it up and I've got the 1/8 drawing in 30 minute. But it was just entering to a dark room,

And, no, as once I got drawings, it took me 5-6 weeks to plan and digest how to build up this puzzle, then searching and choosing Airfoil. Designing a wing structure to accommodate Landing gears, Places for Servos, how to link servos to Aileron and Flaps, and so many other question I couldn't sleep :-). Then I spend , over a week to design formers, followed making files for laser cut, to mount fuel tanks, and run air duct, etc, etc, :-))

It was much more complex than I expected. I believe, the time I spend to cut, glue and sand balsa, was about 10% of time I have spent on whole project,

But, I'm with you, It might looks straight forward, as there are invisible effort & search behind these photos,

Once I finish this one I'll start a F-14 😉 😃

Hello Again,

A full rainy day today so I finished fuselage glass, 25 grams,

At this stage Glass finished, including 5 servos (Ruder, Aileron and Flaps) which are already installed, 3050 gram (6.7lbs). ( without elevator)

I will go next to make elevator, then starting prime 😃

Outstanding work Javad and nice Futura SE.

Takes me right back to the late 90’s flying mine when life was just work, fly, repeat!

Its coming together beautfully!!!!

Javad

Hello Mick,
Thank you for your comment,
Yes, old school heli, the orange one you see is almost brand new, just did 2-3 flight last year. I had it from 90s, but I was away from hobby for about 10 years. Once I get back to hobby, I put it together, but not much fly as I was busy with other projects,

Hi Kevin,

Thank you, It is time I have to resist rushing to finish it and spend some times to go for scale details.

Hello there,

Below key points about Elevator Mechanism:

• A multiple layer of plywoods is the mount, which has installed on tail formers before,
• 4mm birch plywood is cut in x shape & reinforced
• 6mm carbon rod as shaft, going trough a teflon wich is fixed on x shape plywood,
• two 3mm teflon washer has filled the gap between mount& x shape plywood,
• all 3mm ball links,
• ,
  
  
  
  
  
  
  
  
  
  
• rest as can be seen in photos :-)),

WOW - Gotta Luv This Build. Luv Me Some F-4s. Chic

Javad

Thanks Alistair,

Javad

Hi Chic,

Thanks, slowly slowly, its building up :-))

Javad

Hello guys,

Following elevator Mechanism, I build up elevator on top of plywood structure. However, on half way I thought 4mm plywood is little week, so I reinforced plywoods with 2 pieces of 4mm Carbon rod and 75gram carbon cloth,

By finishing elevator, all up weight is 3300 grams, including all 7 servos and linkages. Withouts servos, fuselage and wing together is 2950 grams (6.5 lbs) , which is before primer and paint.

I’ve looked and looked and I cannot find the helium cell 🙂 it’s very light!
We discussed a few areas to increase the glass cloth to 2 layers, but it’s still going to be a ‘shockflier’

Thanks for this thread. You are doing an awesome build job!!!! Really looking to completion and test flying

Javad

Hello there,

To see it better in size, I took 2-3 photos, while I could hold it in different angles, looking it this way, it looks to me bigger than I was looking on table . I'm not tall tough ;-)) 5.5 foot to compare, 168cm,

Sir you have incredible skills!

Dave Wilshere

You should see his Tx cover 😀

Javad

Dear Bob, Dave and Kevin,

Thank you for your nice words, I'm beginner in building a complex airplane like F-4, without support of nice people around me, such as Dave, Hamid, and John (Greenfield), I would stock or fail the project, so thanks to all supporters :-))

Yes, on cold days, I was suffering to fly with cold hand, so I made a Tx cover with a warmer as Dave mentioned, As My general approach it needed to be light😉😀 Build up structure, covered with polyspan and Dope

Javid, superb work my friend. It may be a good idea to make a mold of this superb aircraft so it can be duplicated. In my opinion it is the perfect size. That is an interesting hand warmer, how cold does it get in London?
