INTRODUCTION:

The H-King MX2 3D was designed to be an all-out 3D performer with great, straight precision flying capabilities. It has a great combination of lightweight, durability, and performance with none of the compromises normally found in EPO foam aerobatic models. Michael Wargo, our team pilot, and 3D expert helped fine-tune the MX2 Extreme 3D into the type of plane he enjoys flying. The result is an aircraft that delivers lightning-fast rolling, amazing straight lines,and extreme tumbling, but it also likes to perform all of the low and slow 3D maneuvers pilots love.

The MX2 is the perfect aircraft for any pilot wanting a versatile and capable 3D plane. This MX2 is the next generation of EPO foam designs that are lighter and more capable than ever. Any accomplished 3D pilot will love this plane because it will satisfy the most discriminating pilot. Its high-energy performance defines this plane, but bring it in low and slow, and it is rock solid and easy to harrier and hover.

This Plug-N-Fly 3D airplane is very quick and simple to assemble and is supplied in a striking red, white, and blue pre-printed finish, with carbon landing gear, wheels, and wheel spats. Power is supplied by the pre-installed 3702-900KV brushless motor driving a fine pitch 13x4 composite propeller, and a 60A ESC, this is the perfect set-up for excellent throttle response when performing 3D. Also supplied and pre-installed are 4 x 13g high-speed, metal-geared digital servos, these high-quality servos have an excellent resolution and speed for precise control.

The MX2 Extreme is easy to transport due to its removable wings and is fantastic fun to fly just about anywhere. If you are looking for an airplane to progress into 3D aerobatic flying, and to take your flying skills to the next level, then the H-King MX2 Extreme is the perfect choice.

ASSEMBLY INSTRUCTIONS:

Horizontal Stabilizer Installation.

Apply a thin coat of foam safe glue to the stabilizer mid-section and gently slide it into place as shown.

Check frequently if the stabilizer is level and square to the fuselage as the glue dries.

A small piece of white foam comes with the

fuselage. Apply some foam safe glue and place

into the slot between the lower part of the rudder

post and the rear of the fuselage to further

reinforce the structure of the empennage.

Page 6

Rudder installation.

Insert the pre-installed rudder hinges into the

fin and apply foam safe CA glue to secure in

place. Check frequently to ensure that the

rudder moves freely as the glue dries.

Tail wheel installation.

Insert the tail wheel landing gear wire into the small hole in the rudder. Then install the

plastic bracket on to the rear of the fuselage and secure it using the supplied 3mm

self-tapping screw as shown.

Page 7

Rudder installation.

Install one of the supplied M3 x 35mm bolts through one of the wheel spat outer halves and add a

plywood washer and wheel as shown. Then slide on the inner half of the wheel spat, pass the

remaining part of the bolt through the hole in the carbon landing gear, then secure the spat/wheel

assembly in place by using the supplied M3 nut. Apply some thread locker to the thread to prevent any

loosening in flight. Repeat this process for the other spat and wheel. Secure the carbon fiber landing

gear onto the landing gear mount on the underside of the fuselage using the supplied M4 x 30mm

screws as shown.

Rudder and elevator pushrod installation.

Before you install the pushrod to the servo, ensure the servo control arm is perpendicular to the servo

case. Install the end of the pushrod with the Z bend on into the outer most hole on the servo control

arm. Then connect the ball socket end onto the rudder surface control horn, secure it with the supplied

screw and retaining nut. Apply some thread locker to keep it secure.

Repeat the above steps for the elevator control linkage installation.

Main wing installation.

Install the carbon wing joiner rod through the fuselage. Then slide the left wing panel onto the rod and

feed the aileron servo lead through the hole in the fuselage at the same time. Secure the wing panel by

using the supplied nylon wing bolt. Repeat the above steps for the right wing panel installation.

Prop and spinner installation.

1. Install the prop hub adapter onto the motor shaft.

2. Install the spinner back plate onto the prop adapter, followed by the propeller.

3. Install the washer and the M8 nut, tighten the nut with a spanner. Attach the spinner nose cone to

the backplate using the supplied self-tapping screws. You may need to adjust the backplate and the

spinner cone accordingly by loosening the prop nut and moving it a fraction until the screw holes are

perfectly aligned together.

4. When you are satisfied with the fit, tighten the prop nut

and secure the spinner with the self-tapping screws.

Note: To achieve the best possible power and performance from the power train as well as ensuring you reduce the vibration on the airframe, always balance the propeller and spinner properly before flying.

SETTING-UP THE H-KING MX2 EXTREME 3D:

Travel Settings:

Each flight control must be set to its physical limits. This means as far as it will go, but no farther

than it has to. You set this by selecting the servo, fully deﬂect the surface with the transmitter,

then increase (or occasionally decrease) the percentage to where the ﬂight surface will not

travel any further. Then simply back off a click or two and you are done. Then, deﬂect it in the

opposite direction and repeat the process. This must always be done for rudder, ailerons, ﬂaps

and elevators. Your travel/end point settings must be above 100% to achieve full performance

from each servo.

Rates and Exponential

All rates at 100% for full 3D ﬂying. Put the stick at one third and set to where when you switch

between rates the surface hardly changes. Obviously at the end points it is an enormous difference.

Our Recommended expo settings for low rates is in the 20% range for an aerobatic plane, and expo

in the 60% to 70% range for high rates for 3D.

C of G Position:

95mm to 100mm

Happy Flying!
