How to Make a RC DHC-2 Beaver
After building my first RC model I decided to build Famous DHC-2 Beaver which looks great and fly awesomely well also this airplane has a very wide flight envelope, its perfect for all kinds of flyer starting from beginner to experts. its unbelievably docile in air and flies like a breeze.
Its features the very popular naka 2412 Airfoil which gives its amazing lift to speed ratio. you can choose to fly it as a slow trainer or get the most out of its acrobatics abilities.
Personally, I think the DHC-2 Beaver is stunning, and it would be fantastic if I could create a miniature version of it.
What You Are 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
Design & Schematic's
- Here are the schematics for the plane I designed; simply copy all of the parts onto foam sheet and cut them out using a cutter.
-
Dimensions and other information can be found in the schematics.
The Fuselage
- For making the fuselage refer to design & schematics.
- Copy all the parts of fuselage onto the foam board and cut them with the cutter.
- Now for the structure of fuselage we will make internal strength structure and divide the fuselage into three compartments as shown in the above images.
- We'll stick another layer of foam to cover the fuselage bottom once we've finished with the landing gear assembly.
The Tail Section
- We'll now put the fuselage and stabilizers together.
- Make a cut at the end of the fuselage for the horizontal stabilizer to be inserted.
- Do the same thing with the vertical stabilizer. Make a horizontal cut in the middle and insert the vertical stab.
- Now glue the horizontal and vertical stabilizer to the tale section.
The Wing
- This is the most crucial section, as it determines the characteristics of your airplane.
- Take a thin steel rod and some foam strips and glue them on the dot lines image1 to make the wing.
- Apply heat to the wing and fold it from the dark line as shown in image 1.
-
To create the ailerons, we'll make two 30-cm partial cuts on each ends of the wing, make V cuts, and use packaging tape as hinges so they can move in both directions.
The Landing Gear
- To make the landing gear assembly refer to the schematics and bend the metal wire and attach the wheels using washers and nuts.
- You can use different methods and your ideas to make this part since their are many different ways to make landings gear.
- Once done attach it to the plywood and glue it to the fuselage.
The Motor Mount
- For the motor mount take the motor on the plywood piece, then stick the plywood at the leading edge, keeping in mind that the motor should be facing downwards; because the angle counts, the push will generate downwards, allowing lift to be created.
- Now Glue the motor mount with glue gun in front of the fuselage and cover the motor mount with the packaging tape.
The Electronics
- When it comes to electronics, you should choose properly because they will determine how well your plane performs.
- For the Brushless motor I will recommend Sunnysky as they are more efficient motors as compared to the others.
- For the ESC I will recommend AVIAN ESC or E- flite ESC as they are smart ESCs and works more efficient.
- For lipo batteries I would recommend Spektrum smart batteries as they give more flight time.
- For servos 10g or 20g digital servos will work great.
- For Transmitter and receiver I would recommend Spektrum NX8 as it allows multiple features .
- For installing the control surfaces we have to install the servo's and control horns on the control surfaces such as rudder, elevator and aileron's.
Assembling Everything and Ground Checking Before the Maiden Flight
- We're almost done; all that's left is to foam-coat the bottom and top of the fuselage, as well as create a removable top portion for the front compartment, which will hold the battery.
- Check all the control surfaces before fight and make sure that they are working properly.
- Check CG of the plane before flight.
- Make sure your all electronics are working properly.
We're all set to install the propeller and take the first flight.
Happy Flying :D
