    What do these ratings mean?

    The RAH-66 Comanche was developed for the U.S. Army by Boeing Defense & Space Group, helicopters division and the Sikorsky Aircraft Corp. It was to provide armed reconnaissance, attack and air-combat duties by utilizing advanced composite material which aimed to provide stealth against radar and heat seeking missiles. The program was canceled in 2004 when the Army decided to shift the money to various other aviation programs.

    Heli-Max has just released a scale looking and easy to fly CX version of this great heli which includes everything required to get started, no experience needed. Simply install 8 "AA" batteries in the transmitter, charge the supplied 500mAh LiPo battery and start flying your own recon missions from the comfort of your living room.

    Name: Comanche CX (HMXE14)
    Price: $99
    Height: 6.3 in (160 mm)
    Rotor Span: 10.6 in (270 mm)
    Length: 12.5 in (320 mm)
    Weight: 4.8 oz (136g)

    • Fully assembled Comanche CX heli
    • 4-channel heli radio system
    • 500mAh LiPo battery
    • A/C Wall charger
    Items Needed To Complete
    • 8 "AA" Batteries

    The Comanche CX arrives in a double boxed package and is ready to fly out of the box. All the components are securely held in place by the foam packaging which can also double as a carrying box if needed. It includes an FM transmitter, 500mAh LiPo battery, and wall charger. You will need 8 "AA" batteries for the transmitter.

    Removing the canopy reveals the two motors with purple anodized heat sinks and two servos that are controlled by the integrated speed control and receiver. The battery is installed in the hatch on the bottom of the heli without a need to remove the canopy.

    While the transmitter is pretty basic, it will serve the purpose of getting someone familiar with learning how to fly the Comanche. A great feature that Heli-Max has incorporated in the Comanche is the blade holders which allow the blades to fold and absorb the impact during a crash and they really work. 

    The Comanche CX manual is pretty detailed in showing how to prepare the heli for flight and giving an introduction to how the control sticks will command the helicopter. Useful information if you are just starting out. 

    It also includes a detailed exploded view of the helicopter and a list of all replacement parts detailed with drawings to make it easier on deciding which parts to order after a crash.

    Heli-Max Comanche CX Manual

    Getting the Comanche sortie ready simply involves charging the 500mAh battery with the supplied wall charger and installing 8 "AA" batteries in the transmitter. The battery hatch is located on the bottom of the heli and provides the convenience of not having to remove the canopy before and after each flight. The manual recommends that the heli is laid on its side and not moved for 10 seconds while the battery connection is made to allow for the gyro to properly initialize. Once the battery is connected, the connector and wire can be completely concealed inside the canopy to complete the scale looks of the Comanche.

    The Comanche CX is very easy to fly as it is very stable and does not want to drift or jump around by itself. It would be the perfect first heli for someone getting started in helicopters.

    Taking off from a hard surface, I noticed a tenancy to want to roll backwards as throttle is applied so pay attention to your surroundings until you are familiar with the behavior of the heli on take off.

    Giving throttle on takeoff, the Comanche lifts off around half throttle and maintaining altitude is easily achieved as long as you feather the throttle a little. If taking off from a table, attention must be paid to the ground effects since the heli will want to drop as soon as it clears the side of the table.

    The cyclic response of the Comanche is very tame. Forward and aft cyclic inputs command the Comanche in controllable movements which halt as soon as the sticks are released. I noticed that left and right cyclic were slightly more aggressive. They cyclic does not really pitch the heli as much as just move it in the direction that the stick is pointed towards. This makes it much easier to navigate in small confines where you will most likely fly the Comanche. However it does require that you coordinate your turns with the rudder.

    The tail holds fairly well. The trim on the transmitter can be used to set the nose straight and will need adjustment as the battery drains or if you are changing head speed often. The pirouette rate is fairly slow which will help in keeping the nose straight for novice pilots.

    Landings are also very easy as simply reducing the throttle allows the Comanche settle in on its flexible landing gear. Try to stay out of ground effects as the wash from the rotors seems to want to throw the Comanche around quite a bit.

    The Comanche is a great little heli for the first time pilot looking to get their wings. It provides a stable platform to learn how to hover and get the basic orientations locked down which should be mastered by all heli pilots before moving on to anything else. And for experienced pilots, it allows to get your heli fix for when the weather outside is not cooperating to get out to the field. Not to mention it can do all this with great scale looks and convenience as everything that is required is included in the box. 

    The provided 500mAh battery does allow for around 10 minutes of flight and charges in close to one hour. If you are the impatient type, I would recommend getting a few spares. I especially like the addition of the folding blade grips as I had a couple of encounters with the surroundings and can say that the folding blades completely absorbed all of the damage and did not even nick the blades.

    The coaxial design of Comanche makes it very stable and I was actually able to take pictures of it with one hand while just feathering the throttle with the other. If you do find that sweet spot, you can get it to hover in place for a while completely hands off.

    Overall, the Comanche CX provides as advertised; a fun time with everything included out of the box with no experience required.
