The left stick controls throttle and yaw direction of Tinyhawk II. The right stick controls pitch and roll of the aircraft.
Left Stick Diagram
Right Stick Diagram
Fly Tinyhawk II
Start by powering on your Radio and Goggles. Tinyhawk II comes already bound to your radio and on the right video channel matched with your goggles. Power on Tinyhawk II by sliding the battery into the battery tray and plugging it in. Once the battery is plugged in, set Tinyhawk II on a stable surface so it can calibrate. Calibration takes a few seconds then Tinyhawk II is ready to fly. Tinyhawk II can fly for 4 minutes on a fully charged battery. Land Tinyhawk II when the battery reaches 3.2v; flying any longer can severely damage your battery and is not recommended.
18 emax-usa.com
Arming
Arming refers to setting Tinyhawk II to a fly ready state. When Tinyhawk II is powered on first it will not spin up the propellers until it is armed. Arm the aircraft by first moving throttle to the bottom position. Then move the left switch of the radio to its 3rd position upwards. You will see the propellers spinning when Tinyhawk II is successfully armed.
In the event of a crash always disarm immediately. Failure to disarm in a timely manner can damage Tinyhawk II. Always disarm Tinyhawk II before handling it.
Flying Modes
Tinyhawk II comes stock set in rate mode. This is an advance mode where control sets the angular rate of the aircraft. The AUX 2 switch is set to change this mode on a 3 stage switch. When AUX 2 is in a high state, Tinyhawk II will be in easy mode where control sets the attitude of the aircraft. When the switch is in the middle state, Tinyhawk II will be in intermediate mode.
Easy Mode: This is easy flight control where the maximum angle of tinyhawk II is limited in flight to help limit speed and make flying easier. In this mode control of the aircraft is attitude based. Input from the right gimbal with pitch and roll controls the pitch and roll angle of the aircraft. For example 20 degrees of tilt on roll of the gimbal will translate to 20 degrees of roll tilt on tinyhawk II. Intermediate Mode: This mode has a higher angle limit for higher speed flying with the same attitude control. The only difference is at the end of the gimbal for pitch and roll, it will cause the aircraft to flip in that direction.
19 emax-usa.com
Advance Mode: This mode gives you full control of the aircraft. There is no more angle limit and control is rate based. This means control input from the gimbal sets a rotation rate on said axis.
Line of Sight Flying
To learn how to fly Tinyhawk II start by flying it line of sight (no goggles yet). Power on Tinyhawk II and set it down in a cleared room. Arm Tinyhawk II then throttle up using the left stick to a hover position. Work on maintaining a constant altitude. Pitch and roll Tinyhawk II with the right thumb stick and yaw Tinyhawk II with the left thumb stick.
First Person View (FPV) Flying
Make sure Tinyhawk II and the goggles are on the same vtx channel and that you have a clear area to fly around in. Apply the same principals learned when flying Tinyhawk II line of sight except now work on flying in a forward direction while maintaining a controlled constant altitude. It is easier to learn flying FPV by always moving in a forward direction so always apply a slight amount of pitch using your right thumb stick. You can steer Tinyhawk II like a car using yaw on the left thumb stick. There is an on screen display (OSD) overlaying the video feed from the camera of Tinyhawk II. The OSD displays important information such as flight time and battery voltage. Pay attention to these numbers during flight to know how much battery life is left. Tinyhawk II can fly for a maximum of 4 minutes. When the battery reaches 3.2v, land Tinyhawk II. Drawing the battery below 3.2v is not suggested and can damage the battery. Tips: Work on maintaining a controlled altitude flight to begin while driving Tinyhawk II with pitch and yaw. Do not let the battery go lower than 3.2v. The arm switch activates a beeper when set in the 2nd position (middle); this is useful when looking for Tinyhawk II.
Thank you for purchasing our product! Enjoy Flying Tinyhawk II.
