Freewing Zeus introduction

Thank you for purchasing our Freewing 90mm EDF new sport jet, the ZEUS 90 !

Before you assemble this ZEUS 90 model jet, please carefully read the instructions and follow the correct process for assembly and adjustment. If you encounter problems during assembly and debugging, please first resolve them by referring to the instructions. If the problem persists, please contact the distributor or directly contact us. Freewing ZEUS is a new design, large- sized electric EPO sport jet. It uses the color scheme of blue, grey and white. The shape and details are quite different from our existing sport jet. The new low drag shape and efficient inlet design can enable the new ZEUS to achieve our design goals very well.

Structure

Zeus fuselage is divided into two sections: front and rear, which can effectively reduce packaging volume, save resources, and reduce environmental pollution. By using plastic structural components, interface adapter plates, and screws, the front and rear fuselage can be quickly connected. The main wing and fuselage adopt the QUICK I screw-less portable install structure which can achieve rapid assembly without screws and glue. The QUICK series locking structure will bring you a brand new and ultimate user experience. For example, components such as the horizontal tail and vertical tail continue to use the previous screw fastening structure. However, the optimization of these parts in the design process makes it easier for us to assemble them.

Strength

The main wing is made of 25x EPO raw material and further strengthened with built-in carbon fiber tubes. Its overall rigidity has been greatly improved compared to previous similar models, and it can fully meet the application requirements of 5KG level turbojet engines. The vertical tail and fuselage are continued to be made of 35x EPO raw materials, reinforced by built-in carbon fiber tubes. The mixed use of different raw materials not only achieves higher strength but also effectively controls its weight. ZEUS PNP version is equipped with a 90mm 12 blade EDF power system (# E72216) and a 6S/8S 120A ESC, making it become one of the fastest aircraft in the Freewing history. The reverse thrust function of ESC can make the jet stop faster after landing. All the control surfaces of Zeus are controlled by 7pcs 17G metal gear servos. The front cabin door and front wheel steering are controlled by one 9G MG servo each. In addition, the main wing, tail wing, and fuselage are all connected directly to the control box through adapter plates and ribbon cables, making the battery compartment more tidy and providing a better experience!

Since the birth of the Stinger64, the first Freewing sport jet in 2009, until today’s 90 level Zeus sports jet, continuous optimization and accumulation of experience have enabled us to create this great electric EPO sports jet. The powerful thrust to weight ratio of the Freewing Zeus sports jet will bring you fast throttle acceleration response and unparalleled top speed. The relatively small wing load gives it excellent low-speed performance, making landing easier to control. The Zeus sport jet has excellent longitudinal and lateral static stability, making it easy to maintain the jet’s posture during flight movements, reducing the complexity of operation, and enabling better learning and experiencing exciting stunt actions.

Thank you again! I hope this product can bring you more beautiful flight time!

4. Model planes’ players must be on the age of 14 years old.
5. This plane used the EPO material with surface spray paint, don’t use chemical to clean, otherwise it will damage.
6. You should be careful to avoid flying in areas such as public places,high-voltage-intensive areas,near the highway, near the airport or any other place where laws and regulation clearly prohibit.
7. You cannot fly in bad weather conditions such as thunderstorms,snows….
8. Model plane’s battery, don’t allowed to put in everywhere. Storage must ensure that there is no inflammable and explosive materials in the round of 2M range.
9. Damaged or scrap battery should be properly recycled, it can’t discard to avoid spontaneous combustion and fire.
10. In flying field, the waste after flying should be properly handled, it can’t be abandoned or burned.
11. In any case, you must ensure that the throttle is in the low position and transmitter switch on, then it can connect the lipo-battery in aircraft.
12. Do not try to take planes by hand when flying or slow landing process. You must wait for landing stop, then carry it.

Important additional notes

• The Y-type clevis used in this product is equipped with a transparent silicone ring for secondary reinforcement, which can effectively prevent the clevis from accidentally loosening.
• As shown in the following figure, when you buckle the clevis into the control surface horn, use the silicone ring to cover the clevis.

Center of Gravity

Correct Center of Gravity (“CG”) is critical for enabling safe aircraft stability and responsive control. Please refer to the following CG diagram to adjust your aircraft’s Center of Gravity.

• Depending on the capacity and weight of your choosen flight batteries, move the battery forward or backward to adjust the Center of Gravity.
• If you cannot obtain the recommended CG by moving the battery to a suitable location, you can also install a counterweight to achieve correct CG. However, with the recommended battery size, a counterweight is not required. We recommend flying without unnecessary counterweight.

Dual Rates

According to our testing experience, use the following parameters to set Aileron/Elevator Rate. Program your preferred Exponential % in your radio transmitter. We recommend using High Rate for the first flight, and switching to Low Rate if you desire a lower sensitivity. On successive flights, adjust the Rates and Expo to suit your preference.

Remote Control EXP Setting Suggestion

Aileron EXP curve is shown as below

• Futaba brand Remote Control: EXP A -30
  • EXP B -30
• Spektrum brand Remote Control: EXPO 30% 30%

Elevator EXP curve is shown as below

• Futaba brand Remote Control: EXP A -30
  • EXP B -30
• Spektrum brand Remote Control: EXPO 30% 30%

PNP Parameter Setting

Flight note

A Flap-to-Elevator Mix is required to maintain a good landing when the flaps are deployed. The detail is as below:

• With low rate flaps deployed, mix 2mm of Down elevator.
• With high rate flaps deployed, mix 4mm of Down elevator.

Control Direction Test

After installed the plane, before flying, we need a fully charged battery and connect to the ESC, then use radio to test and check that every control surface work properly.
