Introductions

Introducing FMS's latest jewel. The 2000mm Beaver is going to make its official debut!

The largest propeller aircraft offered in the FMS line features all of our latest concepts and technologies. After extensive tests and product development the Beaver shows excellent performance. While the measured thrust force can reach more than 5000g, the flying weight is only 3800g.

With a classic combination of black and yellow, the Beaver brings a visual wow factor, as well as impressive performance to the flying field. Capable of leisurely low/mid-speed flight this model still maintains aerobatic qualities.

With the latest FMS multi-connect technology, we have streamlined the wiring system making it easier to install, eliminating wiring problems. Easier plane transport is facilitated by the new connectors that allow pilots to remove and replace the wings with just one step. All channels on each wing are brought together in one port. The pilot can install the main wing simply by inserting the port and then securing with four screws.

To make flying the Beaver more fun at night, there are 5 LED lights located on the front of the main wing and at the rear of the fuselage.

The ailerons and flaps are designed to scale. Utilizing the latest EPO52 foam material as well as our new hollow main wing design greatly alleviates the airplane weight.

Electric Retracts and Floats can be purchased separately to modify your model. Electric Retracts will make your model ready to tow banners and gliders. The Beaver’s high powered motor is ready to be put to the test for water take off.

Over the years, FMS has been committed to developing different types of products to meet the diverse needs and interests of pilots. For FMS' first large propeller aircraft, we adopted all of the latest concepts and technologies to bring you a wonderful casual flight experience.

History The DHC-2 Beaver is a general purpose bush plane developed by de Havilland Canada. Though originally used for cargo/passenger hauling and crop dusting, it was also adopted by the United States Armed Forces as a utility aircraft and search and rescue unit. The single-engined, high-wing, propeller driven STOL aircraft appeared in both the Korean and Vietnam Wars and was popular amongst front line men. When production finally ceased in 1967, only 1,657 DHC-2 Beavers had been built.

Get your model ready to fly

Important ESC and model information

The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick is not in the low throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off position. Once the throttle stick is moved to the low throttle or off position, the motor will emit a series of beeps. Several beeps with the same tune means the ESC has detected the cells of the battery. The count of the beeps equals the cells of the battery. The motor is now armed and will start when the throttle is moved. The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the motor is rotating in the wrong direction, simply reverse two of the three motor wires to change the direction of rotation. The motor has an optional brake setting. The ESC comes with the brake switched off and we recommend that the model be flown with the brake off. However, the brake could be accidentally switched on if the motor battery is connected to the ESC while the throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full throttle and plug in the motor battery. The motor will beep one time. Move the throttle stick to low throttle or the off position. The motor is ready to run and the brake will be switched off. Battery Selection and Installation. We recommend the 22.2V 4000mAh 35C Li-Po battery. If using another battery, the battery must be at least a 22.2V 4000mAh 35C battery. Your battery should be approximately the same capacity, dimension and weight as the 22.2V 4000mAh 35C Li-Po battery to fit the fuselage without changing the center of gravity significantly.

The transmitter and model setup

Before getting started, bind your receiver with your transmitter. Please refer to your Transmitter Manual for proper operation CAUTION: To prevent personal injury, DO NOT install the propeller assembly onto the motor shaft while testing the control surfaces. DO NOT arm the ESC and do not turn on the transmitter until the Transmitter Manual instructs you to do so. Tips: Make sure all control sticks on your radio are in the neutral position (rudder, elevator, ailerons) and the throttle is in the OFF position. Make sure both ailerons move up and down (travel) the same amount. This model tracks well when the left and right ailerons travel the same amount in response to the control stick.

1. Move the controls on the transmitter to make sure the aircraft control surface moves correctly. See diagrams below.

Page 15

Check the control throws

Check the motor rotating direction

The motor should rotate clockwise when viewing the plane from the rear.

The suggested control throw setting for FMS MODEL are as follows (dual rate setting):

Tips: On first flight, fly the model in low rate. The first time you use high rates, be sure to fly at low to medium speeds. High rate, as listed, is only for EXTREME maneuvering.

Assemble the spinner and propeller as shown below.

Install the propeller and spinner

Check the C.G. (Center of Gravity)

When balancing your model, adjust the motor battery as necessary so the model is level or slightly nose down. This is the correct balance point for your model. After the first flights, the CG position can be adjusted for your personal preference.

1. The recommended Center of Gravity (CG) location for your model is (70-75mm) forward from the leading edge of the main wing (as shown) with the battery pack installed. Mark the location of the CG on top of the wing.

2. When balancing your model, support the plane at the marks made on the bottom of the main wing with your fingers or a commercially available balancing stand. This is the correct balance point for your model. Make sure the model is assembled and ready for flight before balancing.

Before flying the model

Find a suitable flying site

Perform the range check for your plane

Monitor your flight time

Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be required and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three football fields - a flying field specifically for R/C planes is best. Never fly near people especially children, who can wander unpredictably.

As a precaution, an operational ground range test should be performed before the first flight each time you go out. Performing a range test is a good way to detect problems that could cause loss of control such as low batteries, defective or damaged radio components, or radio interference. This usually requires an assistant and should be done at the actual flying site you will be using.

First turn on the transmitter, then install a fully-charged battery into the fuselage. Connect the battery and install the hatch.

Remember, use care not to bump the throttle stick. Otherwise, the propeller/fan will turn and possibly cause damage or injury.

Note: Please refer to your Transmitter Manual that came with your radio control system to perform a ground range check. If the controls are not working correctly or if anything seems wrong, do not fly the model until you correct the problem. Make certain all the servo wires are securely connected to the receiver and the transmitter batteries have a good connection.

Monitor and limit your flight time using a timer (such as on a wristwatch or in your transmitter if available). When the batteries are getting low you will usually notice a performance drop before the ESC cuts off motor power, so when the plane starts flying slower you should land. Often (but not always) power can be briefly restored after the motor cuts off by holding the throttle stick all the way down for a few seconds. To avoid an unexpected dead-stick landing on your first flight, set your timer to a conservative 4 minutes. When your alarm sounds you should land right away.

Flying course

Flying

Take off

While applying power, slowly steer to keep the model straight. The model should accelerate quickly. As the model gains flight speed you will want to climb at a steady and even rate. The Beaver will climb out at a nice angle of attack (AOA).

Always choose a wide-open space for flying your plane. It is ideal for you to fly at a sanctioned flying field. If you are not flying at an approved site always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards, or soccer fields. Consult laws and ordinances before choosing a location to fly your aircraft. After takeoff, gain some altitude. Climb to a safe height before trying technical manoeuvres, including high speed passes, inverted flight, loops, and point rolls.

Land the model when you hear the motor pulsing (LVC) or if you notice a reduction in power. If using a transmitter with a timer, set the timer so you have enough flight time to make several landing approaches. Recharge the battery and repair the model as needed .The model’s three point landing gear allows the model to land on hard surfaces. Align model directly into the wind and fly down to the ground. Fly the airplane down to the ground using 1/4-1/3 throttle to keep enough energy for proper flare. Before the model touches down, always fully decrease the throttle to avoid damaging the propeller or other components. The key to a great landing is to manage the power and elevator all the way to the ground and set down lightly on the main landing gear. After a few flights you will find the model can be set down lightly on the mains and you can hold the nose wheel off balancing the model on the mains until it slows and gently settles the nose.

Repairs to the foam should be made with foam safe adhesives such as hot glue, foam safe CA, and 5min epoxy. When parts are not repairable, see the Spare Parts List for ordering by item number. Always check to make sure all screws on the aircraft are tightened. Pay special attention to make sure the spinner is firmly in place before every flight.
