Lab 05 - Believer Familiarization

Introduction:

For this lab, me and my group started getting familiar with fixed wing components for an aircraft called the Believer. We unboxed the contents of the Believer kit and started identifying airframe and electronic parts. We layed them on the floor and repackaged the parts on the order they came out of. Once we took the photos of the airframe and electronics, we started making out own blog and instructions for the model.

Visual Reference

Using the provided glue, glue the lock mounts into the fuselage.

Glue the hatch locks to the hatches.

Glue the tail fin adapters to the tail fins.

Glue in the motor mounts.

Glue the tail fin adapters to the fuselage.

Glue one wing adapter to one side the fuselage. Do not glue on both wing adapters! If you do, you won’t be able to install the carbon connecting tubes later!

Mark the area where the opening in the nacelle will be, to mark where not to put glue.

Glue the wing together.

Glue the carbon spar supports to the inside of the fuselage.

Glue the screw bases for the Auto Pilot to the fuselage.

Glue the long pieces of plywood to the back of the fuselage.

Glue the square piece of plywood to the bottom side of the parachute bay hatch.

Once the glue on the wings has dried, glue on the screw bases for the nacelle covers.

Glue on the wing adapters.

Glue both halves of the fuselage together.

After the glue has dried, insert the hatches into the fuselage.

Glue on the landing cushions.

Glue in the plexiglas battery plate.

Glue the servo mount to the wing.

Put glue onto the end of the carbon connecting rod that will go into the already installed wing adapter. Then, insert the carbon connecting tubes into the fuselage, from the side of the fuselage without the wing adapter on.

Put glue on the remaining exposed end of the carbon connecting tube, and then glue the second wing adapter to the fuselage.

Once the glue is dry, install the locking hooks to each of the wing adapters, and tail fins.

Connect the wings and tail fins to the fuselage.

Glue the control horns to all of the control surfaces.

Install tail servos into tail mounts, making sure that the side of the servo with the gear is towards the front of the fuselage.

Install round servo head on servos

Install control surface chuck onto servo heads

(Ruddervators should be able to lock like this with no slop in the controls)

Use plastic inserts to create a proper hinge on all control surfaces

Assemble and install push-pull rods to tail control horns

Install wing servos with double sided tape so that the gear side of the servo is forward. Then install the servo covers.

Assemble and install push-pull rods to aileron control horns

Install brushless motors

Install and secure ESCs and wires inside of the nacelle .

Extend servo cables to reach nacelle

Create male D-sub connectors for the inside of the wings with the following connections: 30A+, 30A-, esc control, servo control. The wires should be able to reach the nacelle from the wing root connection.

Install D-sub connector into the wing root

Connect ESC and Servo connectors to the D-sub and secure wires inside the nacelle

Install nacelle cover

Create female D-sub connectors for the inside of the fuselage with the following connections: 30A+, 30A-, esc control, servo control. The wires should be able to reach the nacelle from the wing root connection.

Install D-sub connector to the fuselage wing root connectors.

Electronics Sections

Since we do not have the same electronics as the blog here is a list of best practices from the blog.

Use clamps and double sided tape to secure wires and electronics

Install GPS in the tail of the aircraft so that its signals have the least interference

Create power bus for servos

Install antenna in the parachute compartment because it is ground facing and has ground clearance

Hold antenna in with a rubber band to prevent damage from landings

Reflection:

This lab was important to understand the components of the Believer airframe and the electronics

that would be housed inside the airframe. By unboxing the Believer kit and identifying all the parts, I

understood how the pieces fit and also how there were also missing pieces in the kit itself. Finding

the missing parts helped my group better identify and inventory the parts before we started assembling.

The blog instructions were particualry useful in identifying what we had in our kit and what was missing.

It also gave us step by step instructions for the Believer and we could compare the two manuals. Overall,

this lab helped us learn how being accountable for your equipment and parts is crucial for any project with

given instructions.
