AMA

We urge you to join the AMA (Academy of Model Aeronautics) and a local R/C club. The AMA is the governing body of model

aviation and membership is required to fly at AMA clubs. Though joining the AMA provides many benefits, one of the primary

reasons to join is liability protection. Coverage is not limited to flying at contests or on the club field. It even applies to flying at

public demonstrations and air shows. Failure to comply with the Safety Code (excerpts printed in the back of the manual) may

endanger insurance coverage. Additionally, training programs and instructors are available at AMA club sites to help you get

started the right way.There are over 2,500 AMA chartered clubs across the country. Contact the AMA at the address or toll-free

phone number below:

IMPORTANT!!!

Two of the most important things you can do to preserve the radio

controlled aircraft hobby are to avoid flying near full-scale aircraft

and avoid flying near or over groups of people.

AMA SAFETY CODE (excerpts)

Read and abide by the following excerpts from the Academy of Model Aeronautics Safety Code. For the complete Safety Code

refer to

Model Aviation

magazine, the AMA web site or the Code that came with your AMA license.

Failure to follow these safety precautions may result in

severe injury to yourself and others.

Use safety glasses when testing the motor.

Do not run the motor in an area of loose gravel or sand;the

propeller may throw such material in your face or eyes.

Keep your f ace and body as well as all spectators aw ay from the

plane of rotation of the propeller as you start and run the motor.

Keep these items away from the prop: loose clothing, shir t

sleeves, ties, scarfs, long hair or loose objects such as

pencils or screwdrivers that may fall out of shirt or jacket

pockets into the prop.

MOTOR SAFETY PRECAUTIONS

GENERAL

1) I will not fly my model aircraft in sanctioned ev ents, air sho ws,

or model flying demonstrations until it has been proven to be

airworthy by having been previously, successfully flight tested.

2) I will not fly my model aircraft higher than approximately 400

feet within 3 miles of an airport without notifying the airport

operator.I will give right-of-way and avoid flying in the proximity

of full-scale aircraft. Where necessary, an observer shall be

utilized to supervise flying to avoid having models fly in the

proximity of full-scale aircraft.

3) Where established, I will abide by the safety rules for the

flying site I use, and I will not willfully and deliberately fly my

models in a careless, reckless and/or dangerous manner.

5) I will not fly my model unless it is identified with my name and

address or AMA number, on or in the model.Note:This does not

apply to models while being flown indoors.

7) I will not operate models with pyrotechnics (any device that

explodes, burns, or propels a projectile of any kind).

RADIO CONTROL

1) I will have completed a successful radio equipment ground

check before the first flight of a new or repaired model.

2) I will not fly my model aircraft in the presence of spectators

until I become a qualified flier, unless assisted by an

experienced helper.

3) At all flying sites a straight or curved line(s) must be

established in front of which all flying takes place with the other

side for spectators. Only personnel involved with flying the

aircraft are allowed at or in the front of the flight line.Intentional

flying behind the flight line is prohibited.

4) I will operate my model using only radio control frequencies

currently allowed by the Federal Communications Commission.

5) I will not knowingly operate my model within three miles of

any pre-existing flying site except in accordance with the

frequency sharing agreement listed [in the complete AMA

Safety Code].

9) Under no circumstances may a pilot or other person touch a

powered model in flight; nor should any part of the model

other than the landing gear intentionally touch the ground,

except while landing.

GET THE MODEL READY TO FLY

Check the Control Directions

1. With the transmitter and receiver on, check all the control surfaces to see if they are centered. If

necessary, adjust the clevises on the pushrods to center the control surfaces.

2. Make certain that the control surfaces and the throttle respond in the correct direction as shown in

the diagram.

Set the Control Throws

These are the recommended control surface throws:

High Rate Low Rate

ELEVATOR 3/8” [9mm] up 3/16” [4.5mm] up

3/8” [9mm] down 3/16” [4.5mm] down

AILERONS 3/8” [9mm] up 3/16” [4.5mm] up

3/8” [9mm] down 3/16” [4.5mm] down

IMPORTANT : For a flying wing to be aerodynamically stable, the neutral position of the elevons needs to

be raised from neutral. To achieve pitch stability, place a ruler on the bottom of the wing and adjust the

neutral position of the elevons so that the trailing edge of each elevon is raised 3/32”[2mm].

Balance the Model (C.G.)

More than any other factor, the C.G. (balance point) can have the

greatest effect on how a model flies, and may determine whether or not

your first flight will be successful.If you value this model and wish to enjoy

it for many flights, DO NOT OVERLOOK THIS IMPORTANT

PROCEDURE. A model that is not properly balanced will be unstable

and possibly unflyable.

IMPORTANT: Mini Delta EP has been extensively flown

and tested to arrive at the throws at which it flies best.Flying

your model at these throws will provide y ou with the greatest

chance for successful first flights.

When checking the CG the model should be in ready-to-fly condition with all

of the systems in place including the battery .The C.G.is located 5.4”[136mm]

back from the fuselage along the leading edge of the wing. Change the

location of the motor battery to balance your airplane at that point.

PREFLIGHT

Identify Y our Model

No matter if you fly at an AMA sanctioned R/C club site or if you fly

somewhere on your own, you should always have your name,

address, telephone number and AMA number on or inside your

model. It is required at all AMA R/C club flying sites and AMA

sanctioned flying events.

Charge the Batteries

Follow the battery charging instructions that came with your radio

control system to charge the transmitter batteries. Do the same for

your motor batteries.

Range Check

Ground check the operational range of your radio before the first

flight of the day. With the transmitter antenna collapsed and the

receiver and transmitter on, you should be able to walk at least 100

feet away from the model and still have control.

ASSEMBLY INSTRUCTIONS

FLYING

Mini Delta EP is a great-flying model that flies smoothly and predictably. Mini Delta EP does not, however, possess the self-recov ery

characteristics of a primary R/C trainer and should be flown only by experienced R/C pilots.

Takeoff

Hold the airplane from the fuselage under the wing and point it slightly “up”. Remember to launch the air plane into the wind. Apply

3/4 to full throttle and launch the plane with moderate force.

Flight

This plane can fly fast for about 6 min utes when flown at full throttle.The airplane is fast but predictable.Get used to the plane at low

rates before switching to high rates as the roll and pitch rates will become extremely quick on high rates.

Flight times will increase if throttle management is practiced. The Mini Delta EP can maintain altitude at 1/3 throttle and it can fly

most maneuvers at ½.The Mini Delta EP is still stable and predictable at slow speeds and it also allows the pilot more time to think

about its reactions.

The Mini Delta EP is capable of loops and rolls, inverted flight and any other maneuver that does not require rudder.On high rates,

it can also perform some stalling maneuvers like walls.

Landing

To initiate a landing approach, lower the throttle and let the airplane lose some altitude. When the model is 2-3 feet [60-90 cm] from

the ground, apply up elevator to bleed off speed and land while maintaining the same heading.

GOOD LUCK AND GREAT FLYING!

Glue the two servos in place with foam safe CA

as shown.

Install the receiver and the speed control in

the fuselage.

Make a small hole on the side of the fuselage

and slide the receiver antenna through it.Tape

the antenna to the leading edge of the wing.

Center the servos with the radio. Install the

servo arms, the pushrods and the faslinks.

Install the motor battery, canopy and receiver

hatch. Adjust the elevons' neutral point, the

throws and the CG.

Place the decals on the plane using the photo

in the front page as a guide.

Go fly!
