This significantly expands the range of applications and makes the aircraft a versatile companion for a wide range of flight areas.

Assembly and assembly

Prefabricated components

As an ARF model (Almost Ready to Fly), many components are already prefabricated. The positions for hinges are pre-drilled or slotted, and lock nuts are pre-installed wherever possible. This preparatory work considerably facilitates assembly and reduces construction time.

Needed equipment

The following components are additionally required for the complete construction:

• 6+ channel transmitter and receiver
• 8 standard digital servos
• Engine (30-40cc petrol engine or Power 160 electric motor)
• Propeller: 17-18 x 8
• Ignition battery
• Motor emergency switch

Customer experiences and community feedback

Transport and storage solutions

The modular design with removable guide and two-part wing facilitates transport. However, special transport boxes or padded bags are recommended to avoid damage. A self-built transport box made of light plywood with foam padding provides optimal protection.

Maintenance recommendations

• Regular check of all connections and hinges
• Annual exchange of fuel hoses in petrol engines
• Clamping loose application films with a foil iron
• Checking of the servos for wear, in particular for the heavily loaded transverse and landing flap servos

Frequent questions and solutions

Servo selection and installation

Question: Which servos are best suited for the large model?

Answer: Servos with at least 10-12 kg of adjusting force are recommended for the cross slides and flaps. Servos with 8-10 kg are sufficient for height and side wheels. High-quality digital servos with metal transmission offer the best reliability. The servo holders provided in the model are designed for standard sizes.

Motorization problems

Question: How can the vibration of the petrol engine be reduced?

Answer: To reduce vibration, it is recommended to install rubber buffers between the motor and the motor carrier. In addition, the propeller should be precisely balanced out. In the case of stronger vibrations, a reinforcement of the motor spant with fiberglass fabric and epoxy resin can be useful.

suspension options

Question: Can the model also be operated with a draw-in suspension?

Answer: Although the model is equipped with a fixed suspension by default, some pilots have successfully installed retractors. However, this requires modifications to the fuselage structure and should only be carried out by experienced model builders. Pneumatic systems have proven better here than electrical systems.

Floating operation

Question: Which adjustments are necessary for operation with floats?

Answer: In addition to installing the Hangar 9 1/4-Scale Swimmer, a reinforcement of the fuselage at the fastening points is recommended. In addition, a water slider should be installed on the side control unit. In the case of electric drives it is especially important to pay attention to the waterproof sealing of the electronics.
