Sukhoi T-50 aircraft model with two 50mm impellers

All previous models built by the author of this model were ordinary pushers, and he did not like the look of the propeller group on the model. which is not very compatible with the appearance of a fighter plane. .

The first models with an impeller, built by the author: “Mirage 1”, “Mirage 2”, “Mirage 3”, “Breeze” and “Frigate”.
Video of flights.





When building the model, the author tried to make it as easy as possible. model due to the low thrust of his impellers.
The main dimensions of the model.


TTX
Span - 820 mm
Wing Area - 25 sq. Dm
Length - 1000 mm
Impellers - 50 mm - 2 pcs.
Regulators - 15/18 A - 2 pcs.
The battery is 2.65 A. 3S
Servos - any
Flight weight - 700 g
The wing load is 28 grams per 1 sq. Dm.

Materials
Ceiling tile (ceiling) - 3.5 mm

Wooden rulers
Wooden slats

Epoxy resin (epoxy).

All details of the model are made from the ceiling in two layers.
Individual elements of the fuselage are made of insulation.




When installing the impeller tubes, another layer of the ceiling was added.



The author offers a very interesting way to connect the layers of the ceiling with double-sided tape.

The spar is made of a cut wooden ruler - 10 mm. A wooden lath is glued along the wing.
The author shares the original way of determining the CT model.

First, achieve good model planning by picking up the load in the bow of the fuselage. And then using a special fixtures achieve equilibrium and make a mark on the model in the place where the supports were.


Here is his device by which he determines the CT model.

The tubes on the impellers are glued from three layers of whatman paper - 200 mm long.
The author mounts tubes and impellers on epoxy.

Regulators are located in the place of good airflow, for cooling.
Battery mounting location.



Balanced the model.

On this, let me finish my story about such two different models and different approaches to their manufacture.
