Install Arms In Matching sockets

• Remove Arms from arm case

• Match Inner Arm Letters to Outer Arms Letters

• Letters indicate the top of the arm

• Push inward to mate

• Arms may be stiff. This is normal

• Secure Latch- Ensure secondary lock is engaged

• DANGER: ENSURE correct arm placement.  A to A, B to B, C to C, D to D.  Improper arm placement may lead to abnormal flight performance.

GPS Masts

• Unfold GPS masts to the extended position shown in the photo

• CAUTION: Improperly deployed masts will lead to erratic flight characteristics.

• Lock mast in extended position using light to moderate pressure on wingnut

Batteries and Cowling

• Insert batteries into battery slots with the balance plug tucked in front of the battery.

• Make sure batteries are centered and secure

• Plug Batteries into power input plugs

  • Note- Power will not be provided to the drone until power plug is engaged during a later step.

Cowling. Place cowling flat on the fusalage. While pushing the surrounding cowling flush to the carbon fiber fusalage, push the retaining tabs into the retaining holes. Ensure that all push tabs are fully inserted and cowling is secure.

Propellers and Motors

• Check condition of the propellers by looking for nicks, cracks or fractures.

• Check motor condition by give each propeller a good spin. The motor should have some resistance but be smooth enough to freely spin a few full rotations.

• CAUTION: Damaged propellers can cause reduced flight performance.

• CAUTION: Any damaged propellers should never be used. Micro-fractures in propellers can result in high velocity debre being released from spinning propeller.

Engine and Exhaust

• Check that the exhaust is securely fastened and there is no play between the head and exhaust mount.

  • Due to extreme heating and cooling the exhaust bolts may become loose between endurance flights. A 4mm T-handle allen driver can be used to tighten the bolts as needed.

• Remove Exhaust Covers if applicable.

  • Exhaust hole covers are optional

• Confirm air filter is secured/ Install if needed.

  • Air filter is removed for shipping and a cap is used to prevent fuel leak.

  • Air filter will cover the carburetor- use flat head screw driver to tighten hose clamp. Confirm that the air filter is securely fastened and is unable to rotate. Overtightening will result in the air filter being squeezed off the carburetor.

Fueling

Checking Fuel Level

• This can be done by weighing the drone. Weigh the aircraft at Operating Empty Weight plus payload and add fuel until you reach your desired take off weight. Be sure not to exceed MTOW.

• Weight Definitions

  • Empty Weight= Aircraft Systems without fuel, oil, or coolant.

  • Operating Empty Weight= None usable Fuel, Coolant

  • Maximum Take off Weight= Fuel and Coolant and Payload.

(Future block revisions of Hybrid Hawk will have fuel level sensors)

• Remove Vent Cap

• Attach Filler Line to aircraft

• Attach Vent Line to Aircraft

• Engage Pump to “Fill” position.

• Follow same steps for removing fuel- Fuel Pump set to “Drain”

Fuel Pump Operation

• Battery: Lipo 11.1V (2s-3s)

• Pumping rate Lipo 11.1V : 1200~1500ml/min

• Charging Jack: XT60

• Weight: 380g (Without battery)

• Caution: Do not rotation without oil and fuel- Doing so will damage pump.

• Recommended Battery: 3s 11.1v lipo battery with XT60 plug-4000mAh - 9000mAh. Hard case is preferred for ruggedness

Power on Boot Sequence

Boot Sequence- The Hybrid Hawk is Equipped with a precharge circuit that reduces sparking when connecting the power plug. Following these steps will ensure smooth operation

• Hold Boot Button- You will hear fans do a self check and aircraft will power on

• Insert power plug- The power plug is a XT90 plug used to power the drone on externally. Only when this plug is engaged will the aircraft batteries be providing full power.

  • CAUTION- BE SURE TO FULLY ENGAGE XT90 POWER PLUG

• Release Boot Button
