Flight Practice - Aerofly Professional Deluxe Anleitung

17. Flight practice

In the following, some fundamental flight maneuvers are described, to give you a short introduction to R/C
model flying. Generally you should use finely proportioned and small control stick movements. For most
maneuvers control stick movements of a few millimeters is sufficient. Try out the maneuvers first in the follow-
mode before trying it in a fixed observer position.
Take off
Begin the flight training with the PT40 trainer model in the follow mode (F7 key). leaving all controls in neutral
position and gently give full power. The model will start to roll down the runway. As it picks up speed, pull gently
back on the elevator. After you are airborne release the elevator stick back to its neutral position so as not to
increase the climb to steeply. Try to keep the wings horizontal with the help of the aileron.
! Hint: Only gentle stick movements are required. After correction release the stick.
With the first starts, the model will roll down the centre of the runway after the acceleration. You can refine your
start technique by trying to maintain the direction at the ground with the help of the rudder, in order to keep the
model on a straight line down the runway.
Turning
Practise this function in the follow-mode first. From horizontal flight, roll the airplane with the aileron over about
to 30 degree from the horizontal.Release the aileron control when you have the model at about 30 degree. To
maintain height during the turn you will also need to pull back gently on the elevator during the turn. For the
recovery of the turn, leave the elevator and roll the airplane with the aileron back to a horizontal flight. Practise
banked turns as well. The larger the inclination, the more elevator you will need in order to maintain the height,
and accordingly the turn gets smaller.
Landing
Before you try your first landing, first try flying in constant height along the centre line over the runway. Also
check out, what distance your airplane can cover with the engine power off. Then fly along the extended center
line toward the runway, control the speed of descent with the help of the engine performance of the model, and
aim at a point shortly in front of the runway. When the model is few meters over the ground, bring the engine
into the low power position and pull back on the elevator, so that the speed of descent is reduced. Without
engine power the model will reduce speed and sink further. Continue to pull the elevator, in order to keep the
model airborne for as long as possible whilst getting closer to the ground. Touch down with the help of the main
landing gear and the tail wheel at the same time. Well, you've managed it!
The landing with the glider runs exactly the same way. Use the air brakes to control your descent angle. You
should plan your approach in such a way, so you fly with semi-driven out air brakes. Thus you are able to
balance suddenly occuring up- or downdrafts with the help of the speed brake.
Loop
Fly horizontally with sufficient speed and then slightly heave the model using the elevator. Hold the elevator in
this position. If the speed is high enough and if the rudder deflection is o.k., then the model will fly a loop. Refine
your technique, by flying the loop completely circular with the help of the elevator. Begin reducing the engine
speed at the highest point of the loop, in order to reduce the speed.
