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.

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

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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
