AN IMPORTANT NOTE ABOUT THE ECU PARAMETERS
(Refined from the as supplied settings)
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 fit
The upper frames carry all the avionics. The
side frames are
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 expec
The drive train follows full-scale concepts
by using a twin shaft approach. The power is genera
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 seasaw 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.
· 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 sui
· No washout assembly.
· No bell mixing arms.
· No direct pitch input.
· No flight loads on the control rods.
The 1:5 scale 206 LONGRANGER fuselage is unique in design. The top section of the cabin houses the mechanics and is removable to gain access to the mechanics for servicing.
The cabin space is
completely open allowing unobstruc
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.

Upon opening the kit, all the major
components & 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.

We recommend using a computer radio such as the JR PCM 10X II.
In order to take 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.
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.
If you are an experienced modeller then you should have all the necessary things to complete this kit successfully.
If you have any questions
about this kit or you are unsure about something then you can contact Rcrotortech by email or visit
our web page www.rcheli.com.au

8. Fit the horizontal stabiliser.
9. Assemble the tail rotor control rod as per the enclosed instructions.
10. Fit the tail rotor control rod assembly to the tail rotor gearbox and tail rotor servo arm using the M2 screws, washers, nyloc nuts and chromed ball supplied. When you are happy with the alignment of the control rod and the positioning of the tail rotor servo, tighten the tail rotor servo mounts.
11. Assemble the tail boom support stays. Slow cure epoxy applied between the end fitting, the spacer and the carbon tube will provide added strength and durability. Attach the tail boom support stays to the tail boom.
12. Fit the complete tail boom assembly to the gearbox boom clamp. Connect the boom support stays to the lower frames and align the vertical and horizontal stabilisers. Threadlock and tighten all screws.
13. Drill a 3.5 mm pilot hole for the M4 x 4 cap screw. Use the tapped hole in the right hand side of the boom support clamp as a guide but be careful not to damage the thread in the tapped hole. Fit the M4 x 4 cap screw and tighten so that the boom cannot rotate. Remember to apply Threadlock to the M4 screw first.
1. Install the radio system, FADEC, batteries (4.8v, 7.2v and 1.2v), switches (radio and oil pump) and gyro.
2.
Install oil pump, fuel pump, gas valve, associa
3. Add oil to the oil tank to a level about 10 mm below the bottom of the blue fitting. We use Mobile Jet2 oil mixed with 15% Moreys oil additive.
4. Fit main and tail rotor blades. Set hover pitch and main blades to +5.5° and at least 10° at full collective. Start with -3° at the lower collective pitch position and adjust according to your style of flying. These values will vary depending on the conditions, weight of the model and your flying style. Use them as a starting point then adjust to suit.
5. For turbine fuel we have had great success with JetA1 mixed with 2.5% Mobile Jet2 oil. Use what is available and recommended by the engine manufacturer.
6. Read all of the instructions again prior to the first flight.
1. Program the FADEC without a pitch or throttle curve in the transmitter program (linear from low to high). Observe the requirements on Page 3-7 of the WREN instructions.
2. The engine start / run trim position on the transmitter should not be the full trim position. We use the centre trim position for the start / run setting and program the ECU at this point. This is called the “ground idle” setting.
3. Prior to flying and with the throttle and trim at the ground idle setting slowly increase the throttle trim to full. This is the flight idle setting. Flight performance will now be more consistent and throttle response will be improved.
1. We have had great success using the Taipan Blue glow plug.
