The Tanár S1 and S2. A trainer model airplane to get started in the hobby (includes small online course with the purchase).
The Tanár S1 is a 3-channel electric RC airplane designed for beginners or even for people with some experience, it does not have ailerons and is maneuvered only with the tail, it is recommended for people without experience in model airplane flight, since this configuration is more stable and excellent to understand the dynamics of the flight.
The Tanár S2 shares exactly the same fuselage as the Tanár S1 with the difference that the wings have ailerons and a less pronounced dihedral, being the S1 wing easier to build. This is ideal for the person who already knows how to control and maneuver the Tanár S1, a plane with ailerons has greater maneuverability and control. Although the Tanár S2 is a trainer model aircraft, it has all the characteristics of a sports type model aircraft, capable of flying fast and doing all kinds of stunts, making the Tanár S2 an aircraft for pilots with more experience as well.

The idea arises to create an airplane with good stability characteristics and strength against impacts, which is suitable for people who want to start in the model airplane and people who simply look for the opportunity to build a quality model airplane, and good flight characteristics, When you buy this model plane, you’ll have access to a small online course where you can learn how to connect and set up the electronics, and even build a foam board plane called Joytrainer mini from scratch.
Recommendations and tips
Before starting the construction of the Tanár S1 and S2 it is recommended to have space for the construction table and the appropriate tools. Also, having the complete electronics of the model aircraft (a 1806 or 2205 brushless motor, lipo battery between 1000-1500mah, 30A ESC, standard size receiver and 4 mini servos type Hitec HS-82mg), a 0.0049 nitro motor can be adapted to it. DC. COX type according to the taste of each person.
The aircraft build board must be at least A1 size, straight and flat, with a layer of Foam board, or have adequate porosity to allow pinning during construction.
As for the adhesives, I recommend the use of white glue for the construction of the plane, except in the joints with metal or some balsa laminate. Another alternative is UHU Hart glue for balsa wood. It is also necessary to use Epoxy for the metallic connections of the landing gear and the linkage.
On this plane, it is recommended that the plating of the wing be done with wood glue since it gives time before it dries to correctly fix the entire sheet in the right position without risk of it being fixed in the wrong position. This is recommended for the entire model aircraft, except for fixing the landing gear on the frames and on the laminate of the fuselage. I also recommend the use of a 15-minute setting epoxy when gluing the fiberglass cloth in the center of the wing, as it gives time to accommodate the cloth and remove imperfections.
It is necessary to have the basic modeling tools such as: X-ACTO type knife, sandpaper block (60 – 120 – 240), at least 50 “T” type pins or pins, strong pliers, DREMEL type rotary cutting tool to cut wire 2mm steel, 1.5mm Allen key and lining material of any kind (I recommend Monokote or Hobbyking covering).
It is always recommended to carefully read and study the entire plane and try to understand and locate all the parts in order to get an idea of how to build the model aircraft. You can see the complete video of the construction and the photographs to guide you in this process in greater detail.
The estimated construction time is depending on the glue and your agility, if slow-drying glue is used it could take between 2 to 3 weeks dedicating at least 1 to 2 hours a day. If a medium-fast drying glue such as UHU Hart is used, the time can be reduced to 1 or 2 weeks.
It can often be frustrating to build a model airplane from scratch, but the key to a successful and frustration-free build is to carefully read the blueprint, instructions, and take your time.
In the end it is an interesting and fun experience to have a model aircraft built with your own hands, which flies and maneuvers better than many similar ARF type aircraft.
I invite you to see the construction video in detail and follow the instructions step by step for a better understanding, it also includes many tips and tricks that will be very useful.
