Report on Aero-modeling Project NUTBALL Model

Foreword

This report intends to brief aero-modelling project conducted by Flt-B 06 KAR AIR SQN NCC (Alva’s Air Wing) on 10th and 11th October 2020.

Motto

Lifting the future beyond vision. The project was inclined towards inspiring NCC cadets by exposing them to aero modeling atmosphere. Light up them in flame of interest to join Air force. The main motto of this aviation lab is to get the closer and briefer look on the fights.

Preceding’s of the day

At first the leader of the group selected which model should be done. We had got Nutball. We started with arranging the blueprints in order and started with the model directly.

  1. Printing the RC Plane Plans and Getting the Parts Ready

In this step, we lay out the plan that we printed before and tape the sheets together.

We then take the full plan and lay it out on the depron sheet and cut the depron sheet accordingly to get the required parts. Also, cut the motor mount out of Lite Ply and drill holes as required by your motor.

      2. Building the Power Pod and the Wing

To build the power pod (fuselage), start by cutting the depron sheet on the red line and remove the depron in between the lines. Fold the sides of the pod together and run a bead of hot glue to keep them firmly in place. Glue the motor mount that we have cut, to the front end of the fuselage. Bolt on the motor to this mount using the nuts and bolts.

 The next step is to build the wing of the aircraft. Cut halfway through the foam on the red line so the foam can easily bend on the line. Cut a bevel edge on the elevator so that it can move freely. Cut all the necessary notches (marked in black) for the servos, tail fin, and power pod to fit into the wing. Fold the sides of the wing so its tips are pointed upward at 1.5 inches. This provides stability during flight.

We will next cut a bevel edge on the tail fin so the rudder can move freely. Then, we glue the tail fin into place on the wing. We use glass fibre tape and hinge the tail fin and rudder together. We then install the servos in place, which are necessary for controlling the elevator and rudder of the plane.

      3. At the end of this step we will have four parts:

  • Wing
  • Power Pod
  • Tail Fin
  • Motor Mount

         4. Assembling the Airplane

Once we have the wing and power pod ready, we go ahead and glue them together. Then, we install the control horn on the elevator and run a control rod from the servo to the elevator’s control horn. We follow the same step for the rudder.

         5. Installing the Electronics

    1. BLDC Motor
    2. ESC 30 amps
    3. Servo motor

We installed the RC receiver, battery and ESC into the Power Pod and connect servos to the receiver as in the below wiring diagram. Note the channels you use for each servo and control them correspondingly from the transmitter. Now your RC Plane is all set for flying.

        6. Flying our New RC Plane

We will use a radio-controlled transmitter working on 2.4 GHz frequency to fly this airplane. I highly advise beginners to learn flying on a simulator before actually flying the airplane. There are a lot of simulators available in the market to start learning how to fly airplanes.

Connections:

Top wire: Yellow (out of the other two)

Channel 1: Rudder                                         

Channel 2: Elevator control                           

Channel 3: Throttle
