Default Damiano F86 1:4

Hi everyone,

this is my new 1:4 F86.



The model was designed by me, all parts are laser cut ad fit perfectly one each other.
Covered with 2mm balsa and 110g/mq fiberglass.
Engine is behotec 220 reduced at 115000 rpm. About 180 N
It is all in wood fuselage, wings, elevator and rudder. It’s about 18 kg without fuel (3.7liters).

As I do, the model was not yet painted for the first flight.
It’s a new model, new airfoil not copy of flying model airfoil, center of gravity was to verified, servo movements has to be checked…A lot of doubt. Target of the first flight was only to land without damages.
Arrived at airfield, in 5 minutes, the model is ready to fly but the springs of the rear gears has low stiffness. I try to run on asphalt and the it moves left and right but when the speed increase it run like on a binary.
I rotate and the model is in the air. In “take off” flight mode at about 30% of trust I put 5 point of trim to pitch and the model fly perfect. No trim on aileron. “Landing” flight mode require 9 point of trim and no aileron trim.
Target of first flight is to land without damage, I have 3-4 minutes to learn how land. First time was enough. It land much better than my best dreams, very easy and smooth.
In the second of 5 flight that I did I retract gears and flaps and…surprise: no trims needed. This is the first time for me, in 20 years of turbine flight. Target of this flight was set trim, movements of servos and try to understand how it stall. Reduced speed ,flaps, gears. The speed is very low but no stall appear. I will try next time.
Official cameraman of our group filmed the third flight, here you can see it:

The other 2 flight of the day was much better than the third, I’m really satisfied!





I want to thank all persons who help me during this job:
First my dad: he is the person who built the model. When the cut parts arrived he call me: ”please, print the drawings, I can start assembling structure” . The same evening I give the drawings to my dad and he answer me: “too late, yet assembled!” He made a beautiful job! No one trim was moved, Thank you Gianni!
Mirce set, for perfect(and fast) laser cut job.
Alewings, for professional cable set and electronic power system, simple to use, absolutely reliable and not too expensive.
Electron retracts: for the quality of product and for fast customer care. I ask them stronger spring for rear legs, they send me 2 couple of springs for free in one day.
Osvy model, for perfect exhaust tube. Very strong and light.

I’m sorry for my bad English.

Now, you have pretty much an instant short-kit.

Any plans on offering the laser-cut pieces for sale?
What airfoil did you end up with?

The cutting job was done by Miroslav Terzic, Serbia. Mirce here in RCUniverse

Cool thanks Mirce I'm going to be a busy boy this year with a F-104 and a F-86 and I'll do it as a Australian Sabre.

Estimate on airframe with gear

- 550 for short kit with tubs, split frame
- 150 for pipe (the ones the Russians sell are pretty good)
- 1000 for electric gear, wheels, retracts
- 300 for balsa wood, glass, epoxy?

Even at 3000 with pipe and gear finished to a moderate looking paint job its looks like it would be worth a try for many people

What do you guys think the time would be for someone who has many years of experience from start to finish paint on airframe?

I wish there was a smaller version of this, 90 inches or so, it would be worth buying two of them for a lot of people

thx in advance

I've haven't built a plane like this since I was young boy I just received the F 104 with in 3 days I had it all frame up now sheeting it.. It's up to you how long it will take to build and finish it and if I keep doing what I'm doing I'll uncoated by the middle of next month and also I've got a Sabre kit coming as well
