Homemade was assembled according to the project of Sergey Aleksandrov AL-701. In the development process, it was decided to abandon the impeller model, as a basis was taken Pusher with UVT, and also the drawings of the Russian Su-34 aircraft were studied. It was also considered a fictional model vertical take-off and landing aircraft from one American film. As a result, the team decided to call the resulting model “Gypersting”.
Brief Specifications
The length of the model is 1270 mm.
The height with the chassis is 390 mm.
The range was 960 mm.
The height of the homemade with the retracted chassis is 280 mm.
The flight weight of the car is 950 grams.
Tools and materials for assembly:
- two motors (Turnigy L2210-1400 rpm (210W);
- Four HXT900 servos (9-gram micro servos);
- two regulators TURNIGY K-Force 40A;
- two multidirectional screws 8 x 3.8;
- battery (1800 ~ 2200mAh 3s Li-po or similar);
- electronics for radio control;
- ceiling tile (a model is assembled from it);
- pine slats;
- expanded polystyrene;
- glue;
- stationery knife, scissors;
- paint;
- wheels to create a chassis and other elements.
The process of manufacturing an aircraft model:
Step one. Platform manufacturing
First of all, a platform is manufactured, for these purposes a single-layer ceiling tile will be needed. The platform is reinforced with pine battens, they are installed on the underside. Also at this stage, the frame is mounted, polystyrene foam is used for these purposes. After installing the retracts, everything is sewn up with ceiling tiles. As glue, you can use hot glue, or special glue for ceiling tiles.
Step Two We create a nose fairing and install OBT
From the upper side of the platform, a polystyrene foam frame is also made, then ceiling tile is glued to it.
Among other things, you still need to make a nose fairing, it has a cabin. At the same stage, the OVT is mounted.
Step Three Step by step we collect the elements of the body
The upper surface of the wing must be seamed with ceiling tiles. As a result, you can see the formation of volume.
You can also notice how the wing profile begins to appear.
As a result, the wing will be created from three layers of ceiling tiles and will be biconvex. In the picture you can see how it looks from the back.
Now you can try on a cowl cowl.
In the picture you can see the final stage of covering the upper part of the wing.
The look of the bow changes, it becomes the desired shape.
At the same stage, you can make various options for the upper part of the fuselage. You need to look for an option to use PGO so that you can increase takeoff power.
Now the keel is trying on.
And here you can see that engines with screws are already installed on the model. You can also see fairings here. So that the motors can cool, air passes through the air ducts that are located inside the wing. As a result, air is sucked in through the front nozzles behind the cab, and exits near the motors through the cowls.
To increase the pH surface, the author decided to install two keels. As a result, the road stability will increase, and the LV area will become twice as large.
It was also decided to abandon the PGO, this option was left.
Now you can see how the model looks after painting.
That's all, the model can be tested.
