Hornet 250 Assembly Manual V1.0 Additional Items Required Items required for flight • 4x 1806 size motors (e.g. Emax 1806 2280KV) • 1x Flight Controller (e.g. CC3D or Naze32 controller) • 4x 5 inch props • 4x EMAX 12A Esc •...
Page 7: Esc Module Assembly
Hornet 250 Assembly Manual V1.0 ESC Module Assembly Step 1: Preparing the ESCs Parts Needed: 4 x EMAX 12A SimonK ESC Recommended Tools: Soldering Iron, solder, de-solder pump & helping hands clamp. 1. Cut away the heat shrink with a knife. Be careful not to cut or damage any wires or components when doing this.
Page 8: Step 2: Assembling The Esc Cluster
Hornet 250 Assembly Manual V1.0 Step 2: Assembling the ESC Cluster Parts Needed: Bulkhead E PCB, 4 x EMAX 12A SimonK ESC (from previous step), Silicone Wire, power connector. Recommended Tools: Soldering Iron, solder, de-solder pump & helping hands clamp.
Page 9 Hornet 250 Assembly Manual V1.0 4. Solder the Auxiliary power cable (not supplied). This is used to power the FPV Cameras, FPV TX etc. Note that this outlet is supplied directly from the flight battery. You need to check that the voltages are suitable for your auxiliary components, if they are not you may need to use a voltage stepdown regulator.
Page 10 Hornet 250 Assembly Manual V1.0 6. Solder the ESC to the PCB board. Make sure you get a good fillet of solder that is cleanly adhered to the copper pads on the ESC and the Hornet PCB. 7. Repeat steps 6 & 7 with the other 3 ESCs.
Page 11 Hornet 250 Assembly Manual V1.0 9. Solder the capacitor to the PCB. 10. Repeat steps 8 & 9 so each ESC has its own capacitor. NOTE: Make sure that the capacitors are connected the correct way round, failure to do so will cause damage when you connect power.
Page 12 Hornet 250 Assembly Manual V1.0 12. Shorten the length of the motor wires for ESC 3 and ESC 4 so they are approximately half the length of the top two. NOTE: You may want to leave this step until nearer the end of the build to get the exact lengths.
Page 13: Frame Assembly
Hornet 250 Assembly Manual V1.0 Frame Assembly Step 1: Carbon Main Tube 1. Take the Carbon Fibre Main tube and using a small hacksaw blade carefully cut through the four attachment points to remove the lid. 2. With a file remove the remaining small bumps.
Page 14: Step 2: Front Subframe Assembly
Hornet 250 Assembly Manual V1.0 Step 2: Front Subframe Assembly 1. Parts Needed: Bulkhead C (flight controller mounting plate), 2x antennae tubes, 2x cable ties. 2. Take Bulkhead C and place an antennae tube between the two small cut-outs, ensure you have the bulkhead plate orientated correctly as shown in the pictures.
Page 15 Hornet 250 Assembly Manual V1.0 4. Fasten the standoffs to the flight controller. 5. Fasten the flight controller onto Bulkhead C. Ensure the USB port is facing upwards. If you are using the 8 pin receiver port attach this now as it is difficult to access once inside the frame.
Page 16 Hornet 250 Assembly Manual V1.0 7. Parts Needed: 2x 6mm dia spacers, 2x 5mm dia spacers and 4x M2.5 X 6mm screws. 9. Fasten the two 6mm spacers onto Bulkhead C with 2x M2.5 X 6mm screws. Do not fully tighten the screws in case you need to rotate the spacers later in the assembly.
Page 17: Step 3: Rear Subframe Assembly
Hornet 250 Assembly Manual V1.0 Step 3: Rear Subframe Assembly 1. Parts Needed: Bulkhead D, 2x 6mm spacers, 1x 5mm spacer and 3x 2.5 x 6mm screws. 2. Fasten the 2x 6mm Dia Spacers and the 5mm Dia Spacer to Bulkhead D.
Page 18: Step 4: Attaching The Subframes
1. Slide the Rear Subframe Assembly into the rear of the tube. The rear of the tube is the end with the AXC logo. Secure the assembly with a single M2.5x6 screw on the top of the body tube. 2. Secure the remaining 5mm spacer into the rear of the body tube with 2x M2.5X6 Screws.
Page 19 Hornet 250 Assembly Manual V1.0 3. As you insert the Front Subframe Assembly into the Main Tube you will need to bend the antennae tubes. Don’t worry about bending the antennae tubes they are quite flexible and will bend back into place.
Page 20 Hornet 250 Assembly Manual V1.0 4. Secure the Front Subframe Assembly with 3x M2.5x6 Button Head Screws. One on the top of the tube and two on the underside. Designs, Images and Content Copyright © Aeroxcraft Ltd. 2012 – 2015...
Page 21: Step 5: Motor Preparation
Hornet 250 Assembly Manual V1.0 Step 5: Motor Preparation 1. Adjust the length of the motor wires: Front motors: 150mm* Rear Motors 100mm* *these lengths may differ depending on the length of your ESC wires. You could leave adjusting the cable lengths until nearer the end of the build if you are unsure.
Page 22: Step 6: Motor Arms
Hornet 250 Assembly Manual V1.0 Step 6: Motor Arms NOTE: Make sure that the threaded holes in the spacers are aligned correctly before attempting to insert the screws. Damage to the screw threads in the spacers may occur if the screws are misaligned.
Page 24: Step 7: Esc Cluster Installation
Hornet 250 Assembly Manual V1.0 Step 7: ESC Cluster Installation 1. If using an FPV antennae then screw in your SMA cable and 90 degree SMA connector onto the Power Distribution Board PCB. NOTE: We recommend using a 50mm long SMA extension cable, which is available to purchase from Aeroxcraft.
Page 25 Hornet 250 Assembly Manual V1.0 3. Feed all the wires through the Main Tube and underneath Bulkhead D. If you are going to use your battery connector on the outside of the Main Tube feed it through one of the grommets.
Page 26 Hornet 250 Assembly Manual V1.0 5. Fasten the ESC module into place using 4x M2.5x6 screws. Make sure the AXC Logo on the PCB board is the correct way up and no wires are trapped. 6. Connect the 2 front motors to the ESC connectors in the body cavity.
Page 27 Hornet 250 Assembly Manual V1.0 7. Pull the ESC the control wires through to eliminate any slack and connect up to the flight controller. Make sure you connect ESC1 to port 1 on the flight controller, ESC2 to port 2 etc.
Page 28: Step 8: Front Module And Camera
Hornet 250 Assembly Manual V1.0 Step 8: Front Module and Camera 1. Parts Needed: FPV camera module, 2x M2x5 Hex Spacer, 2x M2x12 Hex Spacers, 8x M2x4 screws, Bulkhead A and Bulkhead B. NOTE: Using different length spacers will give you different camera mounting angles. Different sized spacers are available from Aeroxcraft.
Page 29 Hornet 250 Assembly Manual V1.0 3. Using pliers slightly adjust the angle of the spacers as illustrated below. The mounting points on Bulkhead B are designed to twist to allow for this. 4. Fasten your FPV camera onto the mounting plate with 4x M2x4 screws.
Page 30 Hornet 250 Assembly Manual V1.0 5. Attach your RX receiver to the rear of Bulkhead B with a sticky backed pad. Make sure the RX is orientated so the antennae can be passed through the aerial tubes. If using a Spektrum Satellite RX or similar with short antennae they can be poked out of the two holes on the top of the body tube.
Page 31: Step 9: Tail Cone
Hornet 250 Assembly Manual V1.0 Step 9: Tail Cone 1. Parts Needed: Tail Cone, Rear LED Module (optional), 10mm grommet, 2x M2.5x6 screws & FPV antennae. 2. Insert the optional LED cluster into the Tail Cone and secure with tape or epoxy glue. The LED cluster can be powered from one of the 5 volt ESC BEC circuits.
Page 32: Step 10: Nose Cone
Hornet 250 Assembly Manual V1.0 Step 10: Nose Cone 1. Parts Needed: Nose Cone and 3x M2.5x8 screws. 2. Secure the nose cone to the body tube with three 2.5 X 8mm screws. Designs, Images and Content Copyright © Aeroxcraft Ltd. 2012 – 2015...
Page 33: Step 10: Battery Mounting
Hornet 250 Assembly Manual V1.0 Step 10: Battery Mounting Cut the Velcro strip into three lengths. Two 150mm lengths and one 350mm length. Thread the longer length through the slot at one end and loop it through a second slot. Do this on the opposite end of the lid.
Page 34: Step 11: Software Setup
REMOVE ALL PROPELLORS BEFORE DOING ANY SETUP PROCEDURES. The flight controller in the Hornet 250 is mounted +90 degrees in pitch and -19 (or +19) degrees in yaw. You need to enter these figures into the flight controller software to reflect this.
Page 35 Hornet 250 Assembly Manual V1.0 The full setup of the flight controllers is outside the scope of this manual. There are many resources on the internet for advice and information. If using a CC3D board then we can recommend watching these videos for advice on PID Tuning https://vimeo.com/52741148...
