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 😉 😃

Javad,

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 😃

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.

Default Elevator,

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.
