FEATURES of the ZEALOUS

Main Frame & Mechanics

This unique model uses a modular main frame to house the mechanics the WREN MW54 turbine and our custom built gearbox.
The main frame houses the eCCPM servos, receiver, and gyro.
The electronics are also fitted within the front section of the main frame.
The upper frames carry all the avionics. The side frames are laser cut anodised aluminium and are supported by a 5mm CNC machined aluminium rail running the length of the upper frames. The control system is a proven 120degree CCPM layout with push-pull security on all axes.

Pod & Boom Version

The lower side frames house the flight battery packs, turbine starting battery, starting gas canister and valves, safety fuel shutoff valve and servo, main power switches gearbox oil reservoir and the turbine fuel pump.
A 1.5 litre fuel tank is housed within the lower side frames directly under the main shaft ensuring that there is no shift in the centre of gravity. Flight times of 15 minutes or more can be expected.

Drive Train - WREN MW54

The drive train follows full-scale concepts by using a twin shaft approach. The power is generated by the Wren MW54 gas generator which feeds the free wheel turbine which drives the mechanics via a custom designed dry sump lubricated gearbox. The unit produces some 8.2Hp.Unlike other turbine models the WREN MW54 Gas Generator produces virtually no unwanted exhaust thrust and the sound is completely realistic.

The CFC Rotor Head

This new and innovative design has simplified the control of radio controlled model helicopters whilst increasing the flight stability.
Although the flybar moves up and down similar to other MFS rotor heads the CFC Rotor Head has some major differences. The collective inputs to the main blades are controlled from the centre of the swashplate via the collective tube. This raises and lowers the flybar seesaw thus changing the collective pitch. There are no flight loads on the control rods as they only control the flybar (hiller) input. All flying loads or blade feedback is shared evenly between the CCPM servos through the centre of the swashplate. This is how the closed loop control system is achieved with zero slop.

The CFC Rotor Head also lacks direct blade pitch input and bell mixing arms. Not having direct blade input gives the head a smooth and stable feel. Flight characteristic can be changed simply by changing the flybar length or paddle size and weight.

Features

• Closed loop flybar control system.
• Full ± 12 deg pitch range without binding
• Positive delta 3 offset with the blade grip control arm on the leading edge.
• Different paddle styles and weights are used to change the flight characteristics to your own flying style.
• Adjustable flybar to blade ratio.
• Superb stability and flight performance.
• Adjustable cyclic input.
• Adjustable phasing angle.
• With fewer parts the rotor head looks clean & uncluttered. This is ideally suited to scale models.
• No washout assembly.
• No bell mixing arms.
• No direct pitch input.
• No flight loads on the control rods.

The Fuselage

The 1:5 scale 206 LONGRANGER fuselage is unique in design in that the top section of the cabin houses the mechanics and is removable to gain access to the mechanics for servicing and the cabin space is completely open allowing unobstructed scale detailing.
The fuel tank has been built into the fuselage as per the full size and sits under the rear seat right on the Centre of Gravity.

The Canopy
The Zealous II Pod and Boom version is fitted with a stylish and strong fibreglass canopy.

Pre-assembly Information
Upon opening the kit, all the major components and parts are bagged by relationship to the different sections of the helicopter. Some components of the Zealous II have been factory assembled. The instruction manual details the assembly of all components, including factory assemblies, should servicing be required at a future time. Pre-assembled components, parts, screws, and nuts required for each step are packaged in the same bag.

Radio

We recommend using a computer radio such as the JR PCM 10X II.
To make full advantage of the Zealous II performance capabilities we recommend using a high quality computer radio system with 120 degree eCCPM mixing. The radio system should have at least 8 channels to use modern heading lock gyros. The radio should also have a minimum of 5 programmable points on both throttle and pitch curves. Servos used should be quality coreless, ball bearing and having a minimum torque rating of 70 oz/in. The tail rotor servo should have a servo speed of 0.11sec/60 degrees or better.

Radio Setup

In this manual we have provided our preferred radio transmitter set up parameters. We suggest that you use them as a starting point for initial test flights and then change the settings as required to suit you style of flying.
