E-flite Piper L-4 Grasshopper ARF Assembly Manual
Flying Your L-4 Grasshopper
Flying the Piper L-4 Grasshopper is a pleasure. With
the lightweight construction and low wing loading
takeoffs are easy as well as landings. Low level
reconnaissance passes across the field are a breeze.
The L-4 is not meant for aerobatics but the occasional
loops or wing overs are not a problem.
The L-4 Grasshopper is capable of flying in light winds
up to 7 mph. The optional 730mAh battery pack will
add that little extra weight to help penetrate mild winds
and extend the flight time. Touch and go’s are a blast.
The L-4 Grasshopper carries itself very well on final
approach. It is happy with a descending approach
to maintain the speed during final. Touch downs are
easily accomplished in a main wheels first or three-
point state.
We hope you enjoy flying your L-4 Grasshopper as
much as we do.
Happy Landings!
Safety Do’s and Don’ts for Pilots
• Check all control surfaces prior to each takeoff.
• Do not fly your model near spectators, parking
areas or any other area that could result in injury to
people or damage of property.
• Do not fly during adverse weather conditions. Poor
visibility can cause disorientation and loss of control
of your aircraft. Strong winds can cause similar
problems.
• Do not take chances. If at any time during flight you
observe any erratic or abnormal operation, land
immediately and do not resume flight until the cause
of the problem has been ascertained and corrected.
Safety can never be taken lightly.
• Do not fly near power lines.
Daily Flight Checks
1. Check the battery voltage of the transmitter
battery. Do not fly below the manufacturer’s
recommended voltage. To do so can crash
your aircraft.
When you check these batteries, ensure that you have
the polarities correct on your expanded scale voltmeter.
2. Check all hardware (linkages, screws, nuts,
and bolts) prior to each day’s flight. Be sure that
binding does not occur and that all parts are
properly secured.
3. Ensure that all surfaces are moving in the
proper manner.
4. Perform a ground range check before each
day’s flying session.
5. Prior to starting your aircraft, turn off your
transmitter, then turn it back on. Do this each time
you start your aircraft. If any critical switches are
on without your knowledge, the transmitter alarm
will sound a warning at this time.
6. Check that all trim levers are in the
proper location.
7. All servo pigtails and switch harness plugs
should be secured in the receiver. Make sure that
the switch harness moves freely in both directions.
