Remember to takeoff 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 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 
engine 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

For reassurance and to keep an eye on other traffi c, it is 
a good idea to have an assistant on the fl ight line with 
you.  Tell  him  to  remind  you  to  throttle  back  once  the 
plane gets to a comfortable altitude. While full throttle 
is usually desirable for takeoff, most models fl y more 
smoothly at reduced speeds.

Take it easy with the Giant P-47 Razorback 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 and lowering the fl aps 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 (or having your 
assistant write them down) 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 fuel level, but use this fi rst fl ight to 
become familiar with your model before landing.

LANDING

One of the keys to landing a giant-scale model is to 
maintain suffi cient airspeed throughout the landing 
approach. An unusually high airspeed is not necessary, 
but those unfamiliar with landing giant-scale models are 
sometimes deceived by the model’s larger size. Larger 
models often appear to be closer than they actually are. 

Additionally, most giant-scale models slow down rapidly, 

thus causing the uninitiated to land short. To avoid this 
initial illusion, make your landing pattern closer than you 
normally might for a .40-size sport model. Also, don’t 
pull the throttle all the way back and leave it there the 
way you normally would. Instead, momentarily pull the 
throttle all the way back, but then advance it a “click” or 
two to keep the engine RPM up and maintain airspeed. 
Once over the runway you can cut the throttle the rest 
of the way and the model will slow for the landing fl are.

The Giant P-47 Razorback ARF may be landed with 

or without fl aps. Flaps increase lift and drag, so the 
plane may be landed slower, thus reducing rollout after 
touchdown (not as much of a factor on grass runways). 

To initiate a landing approach, reduce the throttle while 

on the downwind leg. If using fl aps, allow the model to 
slow before extending them. Continue to lose altitude, 
but maintain airspeed by keeping the nose down as you 
turn onto the crosswind leg. Make your fi nal turn toward 
the runway (into the wind) keeping the nose down to 
maintain airspeed and control. If using fl aps, keep a few 
additional “clicks” of power so the model doesn’t slow 
too much. Level the attitude when the model reaches the 
runway threshold, modulating the throttle as necessary to 
maintain your glide path and airspeed. If you are going to 
overshoot, smoothly advance the throttle (always ready 
on the right rudder to counteract torque) and retract the 
fl aps when enough airspeed is gained. Climb out to 
make another attempt. When the model is a foot or so 
off the deck, smoothly increase up elevator until it gently 
touches down. Once the model is on the runway and has 
lost fl ying speed, hold up elevator to place the tail on the 
ground, regaining tail wheel control.

Note:

  If  ever  the  occasion  arises  when  a  dead-stick 

landing must be performed, do not extend the fl aps until 

certain

 the model will be able to reach the landing zone 

(on dead-stick landings it is common to land with no fl aps 

at all). Without engine power, fl aps can unexpectedly 
reduce the model’s range, thus causing you to come 
up short of the fi eld.

One fi nal note about fl ying your Giant P-47 Razorback 

ARF. Have a goal or fl ight plan in mind for 

every 

fl ight. 

This can be learning a new maneuver(s), improving a 

maneuver(s) you already know, or learning how the 
model behaves in certain conditions (such as on high or 
low rates). This is not necessarily to improve your skills 

(

though it is never a bad idea!)

, but more importantly so 

you do not surprise yourself by impulsively attempting 
a maneuver and suddenly fi nding that you’ve run out of 
time, altitude or airspeed. Every maneuver should be 
deliberate, not impulsive. For example, if you’re going to 
do a loop, check your altitude, mind the wind direction 
(anticipating rudder corrections that will be required to 
maintain heading), remember to throttle back at the top, 
and make certain you are on the desired rates (high/

low rates). A fl ight plan greatly reduces the chances of 
crashing your model just because of poor planning and 
impulsive moves. 

Remember to think.

Have a ball! But always stay in control and 

fl y in a safe manner.

GOOD LUCK AND GREAT FLYING!
