After my second model, the DHC-2-Beaver which was a huge hit, I thought why not make another model that is just for beginners in RC Aeromodelling, which looks beautiful, and is simple to build? I think this Trainer model is stunning and flies much better than the previous airplanes, Also I think it is perfect for those flyers who like to fly slowly and steadily. I searched the web for inspiration and decided to make my plans with a few minor changes.

Please feel free to check out my previous Instructables RC DHC Beaver to get a basic understanding of the electronics and their installation.

Step 1: Materials Required

For the Model -

Rubber wheels or some old toy car wheels https://www.amazon.com/BokWin-Black-Model-Aircraf...
Packaging Tape and Acrylic colors
Foam board or depron sheet https://www.amazon.com/Thickness-Polystyrene-Sign...
Scissor & cutter's
Glue gun
Metal wires
Plywood for landing gears
Plywood for motor mounting

For the Electronics -

RC Transmitter & Receiver
RC Brushless motor
lipopolymer battery 2200 mAh
Digital servos
ESC ( Electronic speed controller )
Servos extension and Y harness extensions
1045 propeller

Step 2: Design & Schematic's

Here are the plans for the plane I designed; simply copy the parts onto a foam sheet and cut them out with a cutter.
The schematics contain dimensions and other information.

Step 3: The Fuselage

Refer to the design and schematics when building the fuselage.
Copy all of the fuselage parts onto foam board and cut them out with the cutter.
Now, for the fuselage structure, we will create an internal strength structure and divide the fuselage into three compartments, as shown in the images above.
Once we've completed the landing gear assembly, we'll apply another layer of foam to the fuselage bottom.

Step 4: The Tail

We'll now assemble the fuselage and stabilizers.
Make a cut at the end of the fuselage to accommodate the horizontal stabilizer.
Repeat the process with the vertical stabilizer. Insert the vertical stab after making a horizontal cut in the middle.
The horizontal and vertical stabilizers should now be glued to the tale section.

Step 5: The Wing

This is the most important section because it determines your airplane's characteristics.
To make the wing, take a thin steel rod and some foam strips and glue them to the dot lines image1.
Heat the wing and fold it along the dark line shown in image 1.
We'll make two 30-cm partial cuts on each end of the wing, make V cuts, and use packaging tape as hinges so the ailerons can move in both directions.

Step 6: The Landing Gear

To make the landing gear assembly bend the metal wire and attach the wheels using washers and nuts.
You can make this part using various methods and your own ideas because there are numerous ways to make landing gear.
Attach it to the plywood and glue it to the fuselage once completed.

Step 7: The Motor Mount

For the motor mount, place the motor on the plywood piece and stick it at the leading edge, keeping in mind that the motor should be facing downwards; because the angle matters, the push will generate downwards, allowing the lift to be created.
Now Glue the motor mount in front of the fuselage with a glue gun and cover it with packaging tape.

Step 8: The Electronics

Whenever it comes to electronics, you should make careful choices because they will determine how well your plane performs.
For the brushless motor, I recommend Sunnysky because their motors are more efficient than the others.
I recommend AVIAN ESC or E-flite ESC for the ESC because they are smarter and work more efficiently.
I recommend Spektrum smart batteries for lipo batteries because they provide more flight time.
10g or 20g digital servos are ideal for servos.
I would recommend the Spektrum NX8 as a transmitter and receiver because it has many features.
To install the control surfaces, we must first install the servos and control horns on the rudder, elevator, and aileron.

Step 9: The Maiden Flight

We're nearly there; all that remains is to foam-coat the bottom and top of the fuselage and to design a removable top portion for the front compartment, which will house the battery.
Before the fight, make sure that all of the control surfaces are operational.
Before taking off, check the plane's CG.
Check that all of your electronics are in working order.
We're ready to install the propeller and take our maiden flight.
