Helicopter kits come in
varying shapes and sizes generally the bigger the helicopter
the easier and more stable it will be to fly. choose a well
known manufacturer as it will be easier to get parts and
setup.
As a general
rule, try and steer away from cheap Taiwanese helicopters
offered on ebay such as: Walkera, Esky, Twister etc.
although inexpensive, these helicopters are glorified
"toys", they don't particularly fly very well and typically
supplied with very basic equipment which can not be re used
as you upgrade to bigger and better models. It's also easier
to learn on a well known model as other club members will
have experience and advice on setup and tips.
Electric Helicopters
Recently with the
innovations in battery technology, electric helicopters can
offer a credible alternative to a nitro model, although flight time
is typically shorter the convenience of "plug and play"
flying without all the hassle of engine tuning and starting
equipment required for a nitro
Electric helicopter can be
seen as the best choice for beginners however here are
couple of things you may not have considered with electric
helicopters:
Pros
- Plug and fly, you can turn up at the field with
helicopter, batteries and transmitter and fly.
- Helicopter is a lot cleaner and quieter than a nitro.
- Less chance of helicopter cutting out in flight
- No ongoing fuel costs
Cons
- Initial upfront investment is higher due to the cost of
batteries and chargers rather than an ongoing cost of fuel.
- Batteries don't last forever typically you will get around
200 charge cycles from a lithium polymer battery.
- If you have a hard crash you could potentially destroy a
very expensive battery.
- Flight times are up to 7 minutes against charging time of
around 1 hour.
- Expensive Li-po batteries can be unstable and "puff up" or
fail if not properly cared for.
Nitro Helicopters
Nitro helicopters are good
work horses, with new synthetic oils the run a lot cleaner
than the old days of mucky castor oil. once the engine is
run in and tuned they can provide hassle free flying. fuel
costs around £18 gallon which will provide about 11 flight
of up to 15 minutes.
Pros
- Lower initial investment than comparable sized
electric.
- Longer flight times up to 15 minutes.
- More practical for a whole days flying with less charging.
Cons
- Can be more tricky to get setup and tuned well.
- Starting equipment required including starter, Fuel pump.
- Messier than electric and will required cleaning and more
maintenance.
- Fuel is always needed and has recently gone up in price.
Helicopter Sizes
Model Helicopters are
now available in varying sizes as a general rule the bigger
the helicopter the more stable it will be to fly, larger
helicopters handle wind better and are easier to see in
overcast conditions, below is a breakdown of the common
sizes:
450 size electric - Some members have learnt to fly with models this size
(Trex 450, Mini titan), they offer a low cost
entry into the hobby however for a beginner at the field,
they can be a bit lively especially in a breeze and can be more difficult to
see. More experienced pilots can fly these size models
in a large garden or sports hall.
500 size electric - 500 size
helicopters like the Trex 500 offer a good alternative to a
the larger 30 size nitro machine to get started. Bigger and easier to
see than the 450 and less affected by the wind. Be mindful if
you want to fly all day you will need 3 - 4 batteries
(around £80 each) and 2 chargers (around £100 each).
30 size nitro - The
30 size nitro is an excellent beginners helicopter, it
allows you a low cost entry into nitro modelling with cheap
parts and long flight times. nowadays it's not
particularly cost effective to but a brand new 30 size as
the price is pretty similar to a 50. but a well looked after
2nd hand Thunder Tiger Raptor 30 is an excellent 1st
helicopter and is easily upgrade to a 50 once your skills
improve.
50 size nitro - 50
size nitro helicopter are a good choice for a
beginner, and will give you a machine that will last as your
skills advance, breakable pars such as blades are slightly
more expensive than a 30 and they use more fuel but don't
let that put you off. The Align Trex 600 sport, Compass
Knight Sport & Thunder Tiger Raptor 50 are excellent
choices.
600 size electric -
Basically the same size as a 50 nitro with a large
battery strapped to the front, the 600 electric is a good
choice, be mindful if you want to fly all day at the field
you will need 3 - 4 batteries (around £160 each) and 2
chargers (around £100 each).
A Helicopter kit is just
that a box of bits containing lots of bags with screws, bits
of plastic and gears etc, building the helicopter is much
like mecano and as a first time builder will take about a
week of evenings to put it together.

Helicopter kits are usually
supplied as just the "airframe" you will need to
add blades, engine, exhaust & radio equipment to finish
your new pride and joy.
Blades
Most helicopter kits are
supplied without main rotor blades. There are 3 different materials to choose fro
Wood - (Around £20)
Wooden blades are the cheapest option and are adequate for a
beginners to novice pilots, however wooden blades tend to
go out of track between sessions as the wood expands
and contracts at different temperatures. This can be
frustrating as you may have to
adjust the tracking each time you fly.
Wooden blades are the
heaviest blade choice which can be good for an inexperienced
pilot as they calm the controls down slightly as are cheaper to replace.
Fibreglass - (Around £30)
Slightly more expensive than wooden blades, fibreglass
blades provide good performance for the novice pilot, unlike
wooden blades they do not tend to go out of track so much.
Carbon - (Around £45)
If you can afford them them, Carbon blades are the best
choice and will give your helicopter crisp control response,
just be aware if you crash they will be costly to replace!
Different size helicopters
obviously require different size blades, as a general rule
500 size use 42.5cm (425mm) 30 size use 55cm (550mm) and 50
/ 600 size use 60cm (600mm).
Tail rotor blades can be
purchased in plastic or carbon however as a novice there
really is no need for carbon tail rotors, you are likely to
land tail heavy at least once and plastic blades will be
more forgiving.
Bling!
if you have seen some of our
helicopter at the field or looked around the internet you
may well have seen "blinged" up helicopters with flashy
anodised metal bits, to be brutally honest this is really
just jewellery for your helicopter, 9 times out of 10 its
not going to make you fly any better and costs you a lot of
money.
Most of the time the metal bits make the helicopter more
"twitchy" which you don't really want when you are starting
off, it's also more expensive to replace when you crash!
As a beginner get a good
basic helicopter and spend the money on fuel and or lessons
at Paul Heckles flight School, the only thing that will
really improve your flying its time with your thumbs on the
sticks.
Buying Second Hand
If you are on a tight budget
then second hand
helicopters can be a cost effective option. Lots of us have
found some real bargains and there are many complete setups
available on auction sites and free adds, these are often
from someone who has been to a model shop and bought the whole
lot and then gone to fly and found it wasn't the sport
for them.
We don't want you to fall at the
first hurdle (it's worth persevering) and would love to help get you started.
Come and meet some club members before you invest your hard earned. Many will be happy to impart their wisdom!
Obviously when
purchasing from auction sites the normal common sense rules
apply, check their feedback and whether they can show it
flying. If you can see
it flying then you could always ask a club member to come
along, if that's not possible then here are a couple of
thing to look out for:
1: Check visually that it is
clean and tidy, don't go on this alone but it is a good sign
it's been looked after.
2: Check for lots of play in the servos.
3: Check for play in the control ball links.
4: Spin the rotor head and listen if there is a lot of
transmission or bearing noise
5: Engine running, is there a "whirring" noise coming from
the engine (this will usually be rear bearings)
6: Check bolt heads to see if they have been rounded off
Don't read too much into
statements like "Never crashed" or "only had 1 gallon of
fuel through it" as this is usually untrue! If it has been
crashed so long as all the broken or bent bits have been
replaced it will be fine.
Another alternative is to buy
from one of the club members, you may find someone who has
an old helicopter or could be talked into upgrading (at least
you have someone to shout at if it goes wrong
.
One last piece of second hand
buying advice is, buy something you can get spares for, you
can't really go wrong with a good Raptor 30 or 50 (V2) or a
Hirobo Sceadu. There are lots of helicopters going
cheap this can be because they are not made or spares
are hard to come by, here is a list of a few to steer clear
of: 1: Morley
Maverick
2: Kalt Barron
3: Robbe Mosquito
4: Robbe Conquest
5: Kyosho Nexus
6: Kyosho Concept
7: Kyosho Caliber
8: MFA Sport
9: Hirobo GPH 346
10: Hirobo Shuttle Z (belt start)
11: Thunder Tiger Raptor V1 (30 or 50) |
