Step-by-Step Build Guide

1. Motor Installation

Installing motors on the Tinywhoop frame Oscar Liang

Begin by installing the motors into the frame:

1. Identify the four motor mounting positions on the Meteor 65 frame
2. Align each Happy Model 802S motor with its mounting holes
3. Select the appropriate-length screws (typically included with motors)
4. Secure each motor with two screws—no need for all four per motor to save weight
5. Ensure screws don’t protrude into the motor windings
6. Avoid over-tightening as this can strip the delicate plastic threads

Pro Tip: Use only enough pressure to secure the motors without stripping the threads. Motor mounting screws should never touch the motor windings.

2. Flight Controller Preparation

Soldering the camera connections to the flight controller Oscar Liang

Before mounting the flight controller, we need to solder the camera connections:

1. Identify the three camera connection pads on the flight controller:

• Camera signal (CAM)
• 5V power (5VT)
• Ground (GND)

1. Prepare the camera wires:

• Yellow wire = Camera signal
• Red wire = 5V power
• Black wire = Ground
• Trim wires to appropriate length
• Strip just 1-2mm of insulation from each wire
• Apply a small amount of solder to tin the exposed copper

1. Soldering process:

• Apply flux to each pad
• Heat each pad briefly with your iron
• Apply a small amount of solder to each pad
• Hold the tinned wire to the corresponding pad
• Briefly touch with the soldering iron until the solder flows
• Start with ground (furthest pad), then power, then signal

Pro Tip: “Flux is to soldering what cocaine was to the 80s” – apply it liberally before each connection. It dramatically improves solder flow and connection quality.

3. Quality Check

After soldering:

1. Clean the board thoroughly with isopropyl alcohol and a toothbrush
2. Check for solder bridges or “balls” that could cause shorts
3. Use a multimeter to check for continuity between pads that shouldn’t be connected
4. Verify each solder joint is secure with a gentle tug test

This step-by-step inspection after soldering each component saves significant troubleshooting time later.

4. Flight Controller Installation

Now that the camera is connected, install the flight controller into the frame:

1. Orient the flight controller correctly in the frame

• Look for an arrow indicating the front direction
• If no arrow is present, the USB port typically faces the rear

1. If the USB port contacts the frame, rotate the board as needed
2. Insert the flight controller into the frame’s mounting position
3. Use the included screws and rubber dampeners
4. Tighten just until the rubber dampeners begin to compress slightly

Note: Proper orientation is crucial for the gyroscope to function correctly. The front of the flight controller must align with the front of the frame.

5. Motor Connection

With the AIO flight controller mounted, connect the motors:

1. Twist each set of motor wires for better wire management and to reduce electromagnetic interference
2. Plug each motor connector into its corresponding socket on the flight controller
3. Tuck excess wire neatly around the sides of the frame
4. Ensure no wires contact the gyroscope (center chip on the flight controller)

Pro Tip: Twisted wires have more tension and stay in place better, creating a cleaner build with less chance of wires getting caught in propellers.

6. Antenna Installation

The ELRS receiver antenna needs proper installation for optimal range:

1. Locate the antenna connector on the flight controller
2. Gently attach the antenna by twisting it onto the connector
3. Position the antenna along the back of the frame, extending upward
4. Apply a small dab of E6000 adhesive or liquid electrical tape to secure the antenna
5. Allow adhesive to dry for 10-15 minutes before handling

Warning: Never power on your drone without the antenna connected, as this can damage the receiver.

7. Camera Mount Installation

Installing the camera and canopy on the Tinywhoop Oscar Liang

Now we’ll mount the camera and its protective canopy:

1. Remove the three front screws from the flight controller
2. Align the camera canopy with the screw holes
3. Replace and tighten the screws, securing the canopy
4. Position the camera in the canopy’s mounting area
5. Apply a small dab of E6000 adhesive to secure the camera
6. Ensure the camera is level and centered in the frame

The E6000 adhesive provides a secure yet removable mounting solution. Unlike zip ties or tape, it won’t come loose during crashes but can be removed when needed.

8. Final Assembly

Complete the build with these final steps:

1. Double-check all connections
2. Verify no loose wires could contact moving parts
3. Ensure all screws are properly tightened
4. Install propellers (direction matters—match props to motor rotation)
