Ground Check and Range Check

Make sure the engine idles, transitions smoothly and maintains 
full power indefi nitely. Shut the engine off and inspect the 
model closely, making sure all fasteners, pushrods and 
connections have remained tight and the hinges are secure. 
Following the radio manufacturer’s instructions to ground-
check the operational range of your radio before the fi rst 
fl ight of the day. This should be done once with the engine/
motor off and once with the engine/motor operating at various 
speeds. If the control surfaces do not respond correctly, 

do 

not fl y!

 Find and correct the problem fi rst. Look for loose 

servo connections or broken wires, corroded wires on old 
servo connectors, loose motor connectors or try relocating 
the receiver antennas away from the motor battery or engine.

FLYING

The Edge 540 ARF is a great-fl ying sport model that fl ies 

smoothly and predictably. However, it does not possess the 
self-recovery characteristics of a primary R/C trainer and 
should be fl own only by experienced R/C pilots.

Fuel Mixture Adjustments

A fully cowled engine may run at a higher temperature than 

an un-cowled engine. For this reason, the fuel mixture should 
be  richened  so  the  engine  runs  at  about  200  rpm  below 
peak speed. By running the engine slightly rich, you will help 
prevent dead-stick landings caused by overheating.

CAUTION:

 (THIS APPLIES TO ALL R/C AIRPLANES): 

If, while fl ying, you notice an alarming or unusual 

sound such as a low-pitched “buzz,” this may indicate 
control surface 

fl utter.

 Flutter occurs when a control surface 

(such as an aileron or elevator) or a fl ying surface (such as 
a wing or stab) rapidly vibrates up and down (thus causing 
the noise). In extreme cases, if not detected immediately, 
fl utter can actually cause the control surface to detach or 
the fl ying surface to fail, thus causing loss of control 
followed by an impending crash. If fl utter is detected, slow 
the model 

immediately

 and land as soon as safely possible. 

Identify which surface fl uttered (so the problem may be 
resolved) by checking all the servo grommets for 
deterioration or signs of vibration. Make certain all pushrod 
linkages are secure and free of play. If it fl uttered  once, 
under similar circumstances it will probably fl utter again 
unless the problem is fi xed. Some things which can cause 
fl utter are: Excessive hinge gap; Not mounting control 
horns solidly; Poor fi t of clevis pin in horn; Side-play of 
wire pushrods caused by large bends; Excessive free play 
in servo gears; Insecure servo mounting; and fl ying  an 
over-powered model at excessive speeds.

Takeoff

If using a brushless motor it is a good idea to have a timer 
set on your transmitter, wrist watch or cell phone. We found 
that the plane can fl y for 5-1/2 to 6 minutes or more on a 

4S 3800 mAh LiPo battery. Set the timer for 5 minutes for 

the fi rst few fl ights. When recharging the battery, note how 
much capacity was put back into the battery. To maintain 
the  performance  of  LiPo  batteries,  no  more  than  80%  of 
the capacity should be drained from the battery on a fl ight. 

Adjust the timer as needed.

Before taking off, see how the model handles on the ground 
by doing a few practice runs at 

low speeds

 on the runway. 

Hold “up” elevator to keep the tail wheel on the ground. If 
necessary, adjust the tail wheel so the model will roll straight 
down the runway.

Remember to take off into the wind. When you’re ready, 
point the model straight down the runway, hold a bit of up 
elevator to keep the tail on the ground to maintain tail wheel 
steering, then gradually advance the throttle. As the model 
gains speed, decrease up elevator, allowing the tail to come 
off the ground. One of the most important things to remember 
with a tail dragger is to always be ready to apply 

right

 rudder 

to counteract engine/motor torque. Gain as much speed 
as your runway and fl ying site will practically allow before 
gently applying up elevator, lifting the model into the air. At 
this moment, it is likely that you will need to apply more right 
rudder to counteract the torque. Be smooth on the elevator 
stick, allowing the model to establish a 

gentle

 climb to a 

safe altitude before turning into the traffi c pattern.

Flight

It is a good idea to have an assistant on the fl ight line with 

you to keep an eye on other traffi c. Take it easy with the Edge 

540 ARF for the fi rst few fl ights, gradually getting acquainted 

with it as you gain confi dence. Adjust the trims to maintain 

straight and level fl ight. After fl ying around for a while, and 

while still at a safe altitude with plenty of fuel, practice slow 
fl ight and execute practice landing approaches by reducing 
the throttle to see how the model handles at slower speeds. 
Add power to see how she climbs as well. Continue to fl y 

around, executing various maneuvers and making mental 
notes of what trim or C.G. changes may be required to fi ne-
tune the model so it fl ies the way you like. Mind your fl ight 
time, but use this fi rst  fl ight  to  become  familiar  with  your 
model before landing. Make sure you have enough fuel or 
battery power remaining to allow a second landing attempt 
in case you have problems with the fi rst one.
