We strongly recommend that before you launch your new glider
using the Hi-Start, or off a slope, you first perform a “test glide.”
Pick a spot that is flat, has soft, tall grass, and is free from
obstructions. You want to first check out the glider’s perfor-
mance, but also check our your performance as a pilot.
Hint:
A good, calm period during the day is very early in the
morning or at dusk, when the wind is calm. You want to be able
to concentrate on what the model is doing and have time to think
about what you’re doing. We will assume you have an assistant
during the following steps. If you are a newcomer to R/C flying,
it’s best that you have an experienced pilot help you.
Step 1.
Range check your radio system and check the control
throws. Make sure the control surfaces move in the proper
direction.
Step 2.
Have the assistant hold the glider under the wing near
the CG and run forward until they can sense the wing developing
lift. Don’t release the glider yet. Look to see if the glider wants to
lift, if not, add a bit of up elevator trim, and try again. Repeat this
process until the assistant reports the glider feels light as they
run forward.
Step 3.
This step may take some practice on the part of your
assistant. What you want them to do now is run forward, but a
bit faster, with the nose of the glider pointed at the horizon, not
nose down or nose up...with the wings level...then throw the
glider forward in a line straight toward the horizon.
Step 4.
When the assistant releases the glider, watch it carefully.
A properly trimmed glider will fly straight forward, gliding to a
smooth landing. If the glider pitches nose down, add up trim. If
the glider pitches nose up sharply and stalls, add down trim.
Step 5.
Turns to the left or right after launch can be adjusted
through use of right or left rudder trim.
Important:
Make any
trim adjustments in small increments.
Step 6.
If you have to make large trim adjustments on your
transmitter, you may have other problems. Make sure the wing
is aligned and mounted properly on the fuselage.
When you have the glider trimmed properly in a “hands-off”
manner, return you transmitter trim switches to their neutral
position, then make the appropriate mechanical linkage correc-
tions to return the control surfaces to their test glide positions.
Step 7.
After you have made the necessary corrections, test
glide the model again to make sure it’s trimmed properly with
the transmitter trims in neutral.
Step 8.
You are now ready to try the Hi-Start launch.
