First flight
Always remember: It is the airflow across the wings that creates lift. Keep the airspeed up at
all times.
The J35 Saab Draken model flies much like a real jetfighter. Speed should be kept up at all
times and flying is all about energy management. Energy will bleed quickly if for example
very tight turns are performed resulting in slow speed and in worst cases, a stall. If the
Draken model is flown in a scale like manner with gentle maneuvers and enough speed, the
model will fly "Like on Rails" with no bad habbits at all. Make sure your place of flying has
plenty of open space as the Draken will cover a lot of distance in a short period of time.
It is highly recommended to use a catapult/bungee system to launch the J35 Saab Draken
model. A catapult/bungee system will launch the model in a predictable way with plenty
airspeed at a nice angle. And it will do it again and again. Check out this Youtube video:

The Draken should be launched with a pull of 6-7 kg and at a 5-10 degree upward angle.
The J35 Saab Draken can be hand launched but the succes of it depends on the person
throwing it and the method used. Never try to throw and control the model yourself. Get
someone with experience in hand launching to throw the model. Do not run with the model
before the throw. It never adds any extra speed and most of the time it messes up the throw.
The Saab Draken has been tested with a variety of launch methods and you will get the best
results with an underhand throw and assisted push at the tail. Grab the model with your
secondary hand just after the hatch and place your primary hand on the exhaust tube.
Throw the model in a 10-15 degree upward angle and try to accerate the model by pushing
at the exhaust. Be careful not to push the tail down or up but push it straight ahead. Add full
power to the EDF just before the launch. After the launch keep the wings level and fly
straight until speed builds up. Do not begin a climb out straight after the launch. Get airflow
across the wings before any maneuvering. Check out this Youtube video to see how best to
hand launch the Draken: https://youtu.be/RtU4rTo-qeM
Tip of the Day
If you intend to hand launch the Draken, you might want to consider investing in a Stabilizer
with launch assist like the Aura5lite from www.flexinnovations.com
Center of Gravity
Before first flight make sure the model will balance at the Center of Gravity, CG which is
indicated underneath the wings as two raised dots. If you lift the ready to fly model it should
balance at the CG marks. If the model does not balance at the CG marks move the battery
forward or backwards until the model balances at the CG mark.
