CHOOSING YOUR FLYING FIELD
The flying field you choose should be a large, open field with grass and a hard surface to take off from. There should not be any
vehicles, buildings, power lines, trees, large rocks or anything else that your helicopter can crash into.
Each transmitter comes with a sticker on the crystal mount showing which frequency that the
radio control system operates on. It's important to check the frequency if others are in the area
before turning on the radio control system. No two models can operate near each other if they
are on the same frequency. If you turn on the transmitter and someone else is flying on the same
frequency, their model will lose control and crash.
If you go to fly at a dedicated R/c flying site, make sure to first become familiar with the frequency
coordination that's in place.
After getting out to your flying field, but before you fly for the first time, you must range test the radio control system. This will ensure
that the transmitter is "talking" correctly to the helicopter. You should follow this procedure before every first flight of the day and after
you have a hard landing, crash, or after a repair.
❑
Turn on the transmitter, then plug in the LiPO battery.
❑
Set the helicopter on the ground and double-check that the transmitter's antenna is fully collapsed. Move the right-hand control
stick on the transmitter several times to check the controls. They should operate smoothly.
❑
Walk approximately 75 feet from the helicopter and move the right-hand control stick on the transmitter once more. Check to make
sure that the controls are operating smoothly at this distance.
RANGE TEST THE RADIO CONTROL SYSTEM
WARNING
If the helicopter does not range check, don't fly! Please refer to the troubleshooting guide on page 15.
CHOOSING A DAY TO FLY
The M.A.S.H. Army Rescue Chopper is designed to be able to fly both indoors and outdoors. If flying outdoors, we strongly suggest
flying when there is little to no wind. Winds above 5 - 10 miles per hour will make the helicopter difficult to control.
If flying indoors, keep the receiver antenna coiled up underneath the receiver. If you're going to fly outdoors,
though, the antenna should be extended and tied to the tail skid. This will ensure adequate reception range
between the transmitter and receiver.
❑
Remove the body by first removing the body retaining screw located on
each side of the body.
❑
Uncoil the receiver antenna, wrap it several times around one side of the
landing gear legs (making sure that the antenna does not cross over itself), then
tie the remaining length to the tail skid.
❑
Reinstall the body, using the screws provided.
WARNING
Do not cut the antenna shorter. Allow the excess to hang down below the tail skid. If you cut the antenna shorter the
radio reception range of the radio control system will be greatly reduced.
