Yes, not easy to get this shot. Find the best position, adjust the camera setting, wait. See the Rules of Third? See the Triangle element? ;p
A bit Q & A about Paramotor:
(modified to suit Malaysian flyer)
How high do you fly ?
Most people fly at around 300 m which is a fair comprimise between seeing a
lot of detail on the ground and safety. Height is safety. If you like to fly low
then you need to accept that if you need to land then you'll have no options
except to land on top of whatever you are flying over. Flying low over trees or
water means you'll have a very exciting time if the engine suddenly quits !
Flying low also makes the engine appear very noisy to those on the ground.
You can fly as high as the air traffic allows in your area (check an air
chart) but typically up to 760 - 3000 m. It's interesting to fly high once but
you lose a lot of detail on the ground and you get no feeling of progress.
How fast do they fly ?
Slowly. My wing flies at around 40 kmh but faster wings can fly around 35mph.
Remember this is air speed and not ground speed. If the wind is 10mph on the
ground then it'll usually be around 16 kmh faster at 300 m (say 32 kmh). Now if I
fly into the wind at this height I'll still have an air speed of 40 kmh but my
ground speed will be 8 kmh (40 - 32). Of course if I fly with the wind then my
ground speed will now be 72 kmh. This is also why it's important to land into the
wind :)
How long can you fly for ?
You're allowed to carry 10 liters of fuel (about 2 gallons) and, with my
wing and motor, that gives me around 2 hours 30 min flying time. So, with no
wind, I could fly for around 75 miles before landing but remember it's wise to
have a little spare fuel just in case the wind picks up while you're trying to
get back to your landing field. Some engines are very economic and allow you to
go for over 4 hours. It's best speaking to owners rather than trusting
manufacturers figures.
How do you get the wing in the air to start off ?
The wing is first of all laid out on the ground. If there is a gentle wind
then the pilot faces the wing (a reverse launch) and gently pulls on the front
lines (risers) and the wing takes off like a large kite and hopefully settles
above your head at which point the pilot will turn round and apply the throttle
to take off. If there is no wind then the pilot has the wing laid out behind
him, they then walk forward pulling the wing into the air behind him (a bit like
trying to fly a kite when there's no wind).
This all sounds simple but bear in mind you're carrying approx 27 kg of motor,
the propellor is whirling around just behind your head and the wing is about 10
times the size of the largest kite you've ever seen before.
How do I take off ?
Let's assume the wing is in the air above you. You apply FULL throttle and
keep your back straight - this ensures the blast from the prop goes in the right
direction. You'll run for a short distance until the wing picks up speed and
you'll notice that you feel lighter as the wing takes your weight - do not just
jump into the seat at this point as all that happens is you usually just push
the spining prop into the ground/grass and you'll see bits of propellor flying
off in all directions. Just keep running untill you're well off the ground.
Remember to keep all movements smooth - the more you jump around the more you
upset the wings lift.
It is also essential to keep the wing going straight into the wind by
stearing it with the brakes and keeping your body directly under the center of
the wing.
What controls are there ?
The good news is that once you're in the air then flying it is simple.
There's a throttle that controls the thrust from the propellor. More thrust
means you gain height and less thrust means you lose height though your actual
air speed will never change (mine is around 25mph).
There are brake lines on either side of the harness, pull the left brake to
turn left and right to go right. You can pull both brakes together to slow the
wing down but there is a risk of the stalling the wing. Some pilots like to fly
holding onto the brakes all the time while others leave them alone until they
need to turn.
There are also trimmers and speed bars on many wings, these allow you to
alter the shape of the wing to make it fly faster or slower. It's best to wait
until you have some time in the air before playing with these.
What happens if the engine stops ?
This is a bit like just letting off the throttle - you start to lose height.
If the engine won't restart then you'll need to pick a landing spot and prepare
to land. Paramotors are quite safe and can land in very tight spots - I've
landed in a friends garden.
Is the engine heavy ?
Yes it's heavy and no matter what paramotor specs you read they are allways
heavier in real life. There's also the weight of fuel approx 5kg and perhaps a
reserve (3kg). The good thing is the wing takes the weight the moment it's
flying above you're head.
Do accidents happen ?
Paramotors are slow and easy to land making them quite safe and they'll just
glide to the ground if the motor stops. The most common accident is sitting down
to earlly on take off and simply breaking the propellor. While it's relatively
safe as far as flying goes it is still flying and you should allways be carefull
and get trained properly.
Do I need a reserve parachute ?
That depends on you, many say the wing is already a fully deployed parachute
so why bother with another while others feel much more comfortable with the
extra safety of a reserve. The reserve has to be big enough to take your weight
and that of the motor and slow you down enough to land safely.
Where can I fly ?
You can't fly over built up areas, you must be at least 150 m from people at
all times and you should also stay away from clouds simply incase other aircraft
don't see you in time.
Where do I learn ?
Courses are available throughout the country and abroad. Unless you are very
lucky in life then it's probably not worth the risk of teaching yourself. What
you'll save on course fees you'll spend on broken equipement.
Who should I learn with ?
There are a number of organisations for paramotoring, don't ask me why :-
BHPA : They primarily deal with paragliding but will also teach people
to paramotor. If you want to paraglide as well as paramotor then this is
probably your best bet. They also have third party insurance and a magazine. The
only hastle is the time spent waiting for the correct weather so you can learn
to paraglide when you just want to paramotor.
BMAA : They only deal with powered flight and it is quicker to learn
through them. Their qualification is the equivalent to the BHPA one. They have a
magazine but don't have third party insurance. I learnt through the BMAA.
Independant instructors : Many people have been flying for a long time
and don't wish to join either organisation so have set up independant schools.
It's best to talk with people regarding how good they are. Many people are very
impressed by some independant instructors.
Third party insurance ?
Being insured sounds great but in actual fact third party means the only
thing that's insured is the ground or whatever else you hit. Up to you really.
How do motors differ ?
Power : Measured in hp for horse power or Kg thrust. Heavy pilots
need more and lighter pilots need less. Having too much power for your weight
just means your carrying extra weight and burning too much fuel. Power also
comes from the size of propellor - see below.
Weight : Everybody wants a light paramotor but you also need enough
power to lift you off the ground and powerfull paramotors tend to weigh more.
Also bear in mind that the specs for a paramotor are rarely accurate and weight
in particular.
Economy : Measure in litres per hour. The worst economy engines only
allow you to fly for an hour while the best can give up to 5 hours. Bear in mind
it can be cold when flying and, I don't know about you, but my bladder is ready
to give up after a few hours!
Noise : If the engine is very noisy then you'll just find people don't
like you flying near them and you'll get many complaints from people living near
to where you fly. Try and respect others and move away from farm houses and
villages as soon as you can rather than continually circling over their heads on
a Sunday morning. I wish my own engine was quieter than it is but such is life.
Fuel type and amount : Nearlly all engines are two strokes but Paul
Bailly has a 4 stroke engine out as well. With two strokes you need to mix oil
into the petrol before using it. It sounds complicated but is actually quite
easy. At some point we might have direct injection 2 strokes but none have been
built yet. Obviously the more fuel you have (up to a legal limit of 10 liters)
then the longer you can fly for.
Propellors : Propellors come in different sizes, larger props mean
more thrust but they can also produce more torque reaction which can make things
difficult for the pilot. A large prop also means you require a large cage on
your back which can make things difficult during a forward launch.
Cages : The cage protects you from the propellor. They can be built in
aluminium, steal or titanium. They can come in many parts or not come apart at
all. Many parts make it easier to transport but does also weaken the structure a
little.
Electric start : Some motors are manual while others are electric
start. Having an electric start adds weight to the unit but does make life
easier. My engine also charges the battery as you fly allong just as it does in
your car.
Hang points : This is where the lines from the wing attach to your
harness. High hang points give a more stable flight but make it more difficult
to stear while low hang points allow you to stear by simply leaning one way or
the other. It's great being able to fly allong with low hang points feeling in
total control of the wing but then with high hang points it's great being able
to fly through rough air and not feel your about to be thrown out your seat.
Your choice.
Price : Hopefully the price reflects the quality and features on the
machine. It's up to you how much you want to spend.
Location : If you have a supplier just round the corner then they will
be much more accessible than one based in another country.
What is torque reaction ?
As the propellor turns in one direction it also wants to make you turn in
the other direction which in turn adds more weight to one side of the wing and
you end up turning in that direction. It can be quite annoying flying allong
permanently turning in one direction.
To avoid this some manufactures offset the weight of the engine, others fly
with one brake permanently on (annoying to do in practise) others adjust one
trimmer to be slightly more braked to provide the same affect without needing to
raise your arm. Some harnesses have torque straps which cancel the affect by
redistributing the weight but this does means another strap to adjust while
flying.
What other gizzmos can I buy ?
Altimeter : These tell you your height in feet or meters. You'll
probably be able to guess your height with experience but it's a good item to
have. They work by air pressure and need to be set before taking off. I have a
watch that shows my height but watches can be difficult to read clearly.
Vario : This tells you how your height is changing. Your height alters
depending on the throttle setting or whether you are in lifting or sinking air
caused by thermals etc. I don't have one but would like one.
GPS : GPS units are now tiny. They will show you your height, speed
and direction. They can store routes and allow you to easily follow them while
in the air. Best of all they will show you the way back to where you took off -
I'm terrible and would be totally lost without one.
Compass and ar chart : An air chart allows you to see where you are
allowed to fly and to what height. If you fly cross country then a compass can
be very usefull.
Monocular : A bit like a very small telescope. I find them usefull as
I can read road signs and work out where the hell I am.
Wind meter : Can be usefull while on the ground and preparing for take
off just to check the wind speed and see if it is gusting etc. With time it
get's easy to judge the wind speed by feel.
Wind sock : Put one up in the field you'll take off from and you'll
know which direction the wind is comming from and roughly how strong it is. It
comes into it's own when you are landing and want to check that the wind is
still blowing in the same direction !
How much does this all cost ?
Depends on whether you buy new or second hand. New paramotors are available
from RM 6500 to over RM 25000 while second hand might be available from RM 6000. New
wings cost between RM 6000 and RM 12000 and second hand wings might be from RM 3000 up.
You should budget for training (RM 6000), a flight suit (RM 900) and probably a GPS
(RM 600).
On going costs are quite cheap, 3 hours flying for me is 10 litres of normal
petrol and perhaps RM 30-60 to a farmer for the use of his field.
Will I get to fly often ?
You'd think that because it's cheap to run, easy to fly and you just put it
in the back of the car and drive to the field then you'd be flying every
weekend. But no, either the weather is too windy / rainy or the wife (husband)
points out that they never see you. In the end you'll be probably fly for around
20 hours per year.
So is it worth it ?
Defnitely. It's a fantastic feeling floating through the air, looking down
on the world while sitting in some "Heath Robinson" contraption. Even if you
only ever fly once, you'll annoy everyone for decades with endless stories.
