Consult local laws and ordinances before choosing a ﬂ ying location.

NOTICE: This is not a high-speed sailplane. Avoid prolonged high speed dives

or damage may result.

Range Check your Radio System

After ﬁ nal assembly, range check the radio system with the aircraft. Refer to

your speciﬁ c transmitter instruction manual.

Choosing a Launch Area

Your local AMA radio controlled aircraft ﬂ ying ﬁ eld is the best location for

ﬂ ying. However, if you do not have access to such a ﬁ eld, many other open

areas will work. Avoid possible damage to your launch system and aircraft by

launching only in areas clear of brush, trees and other obstacles.

Hand Launch

Hold the Ka-8 fuselage under the wing. Launch the sailplane into the wind with

the wings level.

Hi-Start Launch

A Hi-Start launch kit consists of elastic tubing connected to a tow line. A good

Hi-Start launch propels a small sailplane 200–300 feet off the ground, ample

height for seeking thermals. The E-ﬂ ite Hi-Start (EFLA650, sold separately)

includes a bright parachute to make it easier to ﬁ nd the end of the line and to

align the Hi-Start with the wind in preparation for the next launch.

You may need assistance to safely launch your aircraft using the Hi-Start. On

your chosen ﬂ ying ﬁ eld, anchor your Hi-Start the furthest point upwind so that

you can launch into the wind.

CAUTION: Avoid driving a stake into buried utility lines or damage and

injury could result. Contact local utility authorities for assistance if needed.

Launching

1. Choose an anchor spot in ﬁ rm soil and drive the stake at an approximate

45-degree angle to your chosen launch path (see image A).

2. Slide the rubber loop through the open section of the stake. Pull on the

assembly to ensure it is securely attached to the stake and the stake is

secure in the ground.

3. Unroll the assembly downwind from the stake, ensuring there are no

tangles or knots. Once your assembly is completely laid out (but not

stretched), slowly walk away from the stake, stretching the rubber.

4. Walk approximately 120–150 ft (36–46 m) and attach the string loop to

the Hi-Start hook on the bottom of your airplane. Keep a ﬁ rm grasp on your

Hi-Start and your aircraft. Ensure your transmitter and aircraft are powered

on and bound together.

5. Toss the aircraft into the wind at a 30 degree upward angle (see image B).

During launch, it may be necessary to use the transmitter for small correc-

tions before the sailplane reaches soaring altitude.

In normal wind conditions, the Hi-Start will unwind to approximately 450 ft

(137 m) and stretch an additional 100–120 ft (30–37 m). Increase or decrease

the stretch distance according to wind strength. Stretch the Hi-Start less on

windy days.

NOTICE: Do not exceed 180 ft (55 m) when stretching the Hi-Start to launch

your sailplane.

Tip: For your ﬁ rst launches, elevator input should not be necessary. Use the

rudder to keep the airplane straight and use the ailerons to keep the wings

level during launch. After you become proﬁ cient at launching, apply approxi-

mately 1/4 up elevator to increase launch height, however, too much elevator

may cause the airplane to stall.

When the sailplane reaches its maximum launch altitude, the ring should fall

from the hook. If the ring does not fall, ﬂ y upwind or tap the down elevator.

Maintenance and Storage

Extreme and/or prolonged heat decreases the life of rubber cord. Store the

assembly in a cool, dry place, loosely wound on a spool.

NOTICE: Avoid leaving the assembly in an automobile.

Hi-Start Precautionary Guidelines

• Make sure the stake is securely anchored. Check throughout the day to

make sure the stake is not loose. Reposition the stake if necessary to

account for changing wind conditions.

• During the launch, make sure there is no one between you and the anchor

stake.

• Do not over-stretch the rubber. Doing so can over-stress the airplane,

causing wing failure.

• Periodically check all knots. If the rubber or string shows wear, replace the

assembly.
