3D (flying)

High performance flying, usually combining two maneuvers at once. For example, mixing a loop and a roll, to loop while rolling etc...

Aileron

This is really an airplane term, but is easier to say than "cyclic roll." Ailerons are what banks a plane left or right, but does not really exist on a helicopter.

Autorotation

A maneuver to land in the case of engine failure; the momentum of the rotor blades can be just enough to slow the heli down just before landing

Ball Link

Connections that allow for adjusting controls using a ball on one end, and a link that "snaps" onto the ball on the other.

Binding

A bad condition where the control ajustments can not move as far as the maximum servo travel. This puts extremely high torque on the servo constantly and can ruin a servo with time.

CCPM

Cyclic-Collective-Pitch-Mixing, CCPM mounts the servo's pushrods directly to the swash plate at 120 degree increments, like an equilateral triangle. With these three servo's the swash plate can be tilted in any direction, and when they all mo ve in the same direction the swash plate can be raised and lowered. All the mixing is done electronically by the transmitter, which means you MUST have a ccpm compatible transmitter

Channels

There are two types of "channels" when talking about R/C. One is the channel the Tx transmits on, the other is how many control surfaces a Tx can control.

Cyclic

Describes the controls which adjust the horizontal attitude of the helicopter, as in roll left-right and pitch forward and backward. Both of these movements are controlled by the right stick.

Dual Rates

A feature of some Tx models which allows a person to flip a switch to make the controls more or less sensitive.

Elevator

This is another airplane term, but is easier than saying "cyclic forward / back." The elevator is what pitches the plane forward or back, to dive or climb, but does not really exist on a helicopter.

ESC

Electronic Speed Controller.  An electronic device that takes the power from the battery pack and the signal from the receiver and measures a certain amount of power to the motor.

Exponential

A feature of some Tx models that allows a person to program in different control sensitivities depending on the position of the stick. Usually, this means the further the stick movement, the faster the controls. This allows the middle area of the controls to be less sensitive, but also allows full servo travel on the outer limits of the controls.

Failsafe

A feature of some Tx and Rx models that support PCM. Failsafe is used so that the servo's go to a predefined position if the signal is lost. In an airplane this can be to go to a low idle while putting the plane in a gentle turn, but in a helicopter it is not as useful since helicopters are naturally unstable there is no predefined setting to prevent a crash.

Feathering Shaft

A rod which helps support the rotor blades and give them more ridged strength. A flapping head has two feathering shafts (one for each blade) and a sea-saw head has one feathering shaft (running the span of the head)

FFF

An abbreviation for Fast Forward Flight. Usually in excess of 50 MPH, or near the maximum speed of the helicopter.

Fixed Pitch

A term that describes a helicopter with no collective adjustments. This means that you control the height strictly with the rpm's of the rotor blades. These are easier to maintain, stronger, and simpler to build but lack major feature s of the collective (variable pitch) type. For one: you can NOT do autorotations with these helicopters and the "vertical control" is much less responsive than the collective of a "standard" heli.

Gyro

A device used to help stabilize the yaw of a helicopter. They come in three forms right now. Mechanical, Piezoelectric, and Piezoelectric with heading hold. Mechanical gyros use a real spinning disk inside a small enclosure and help resist the yaw due to the torque of the main rotor blades by adjusting the tail rotor pitch. Piezoelectric gyros do the same thing, but are more accurate / responsive. See Heading Hold for the third type.

Idle up

A feature on most transmitters that will not allow the throttle to fall below a minimum setting. This is useful because the vertical portion of the left stick simultaneously controls throttle and collective. When flying inverted you need negative collective, you do not want your engine to go to idle when you move your stick all the way down, so idle-up will keep the RPMs high so you can maintain inverted flight indefinitely. Effectively putting a "cap" on the low-end of the throttle

Loctite (Red / Blue)

A special glue for holding metal to metal screws in their sockets so they don't come loose in a strong vibration environment. Loctite is color coded by strength, red being the strongest and blue being medium. Most people use blue locktite because if red is used the screws may never come out again.

Mixing

A term that describes a function of many transmitters that allows one control movement to affect more than one control surface at a time. Revolution Mixing is an example of this, but mixing can also be used to add power when you input large cyclic movements.

Nose-In

A term that describes hovering or maneuvering with the nose of the helicopter pointed at the person controlling it. This is a advanced step in the learning stages of flying a helicopter because both roll and yaw are backwards in relation t o the controller

Servo

A device that can turn a lever arm one way or the other with many points between the two extremes. These adjust all the control points of a R/C vehicle.

Stabilizers

There are two stabilizers, the horizontal and vertical. These help the helicopter to weathervane, so that while in forward flight, the helicopter points into the wind. 3D fliers will have smaller stabilizers so that they can fly sidew ays / backwards faster without weathervaneing. The vertical stabilizer also prevents the tail rotor from hitting the ground.

Sub-trim

This is a feature of many transmitter models that allows you to adjust the trim of control surfaces while still having the trim control on the Tx centered. This way you have full trim adjustment while flying.

Swash Plate

A device that the control arms spin around on so that the pitch of the blades is changed depending on their relative position to the helicopter.

Throttle Hold

A feature that comes with many transmitter models. The opposite of Idle-Up, as in, this switch will keep the throttle at idle so that you can increase the collective without gaining high rpms / power. This switch can be used as a "s afety" switch while you carry your heli to the flight line, but is more commonly used to practice autorotations or if tail rotor control is lost causing the heli to pirouette rapidly opposite rotor blade direction, because when the engine is at idle, the tail rotors loose power so the heli will slow down it's pirouettes and you can autorotate to the ground in a more controlled manner. It is also advisable to hit this switch in the case of an emergency so that if the heli hit something it has no power bei ng applied to the rotor / tail blades.

Torque

Torque is applied to the body of the helicopter because of the engine spinning the rotor blades, this causes the helicopter to want to spin in the opposite direction of the rotors.

Training Gear

Larger landing gear so that landing at a angle is less dangerous. Beginners use these while learning to hover and they typically are made of two crossing sticks with whiffle balls on the ends.

   



  Tips Pilih Jenis Heli,Sim Dan TX

• beli Sim Phoniex 4.0
• beli heli kit  cth: torquetube,motor,fbl unit,servo,esc dari hobby wing paling tidak
• lipo 35-55c keatas dan elakkan brand tymax/turnigy

Clone Kit Gred A

• ALZRC
• TAROT
• KDS

3 GX

TENTANG LI-PO BATTERI

• LI-PO ialah  lipolymer batteri
• Li-Po 6 cell bersamaan 22.2v 
• 1 cell nominal voltage 3.7 x2 = 22.2v
• lipo penuh sepatuttnya 4.2v tetapi bila guna,drop dan stabil pada 3.7v nominal
• mesti berhenti main bila bacaan 3.8v setiap cell
• Mah adalah miliampere merujuk kepada capacity kandungan arus yang disimpan dalam 1 pack lipo

1. 2 CELL 7.4V
2. 3 CELL 11.1V
3. 4 CELL 14.8V
4. 5 CELL 18.5V
5. 6 CELL 22.2V
6. 7 CELL 25.9V
7. 8 CELL 29.6V
8. 9 CELL 33.3V
9. 10 CELL 37V

• 3300Mah bererti 3300miliampere @ 3.3A
• C rate merujuk kepada beberapa kali boleh shoot current cth: 3300 mah 35C 6S
• Perkiraan boleh shoot current = 35 x 3.3A = 115.5A. bermaksud lipo tahan shoot out current sebanyak 115.5a sahaja,lebih akan kembung
• lagi tinggi C rate lagi mahal harga Li-Po

 SEBELUM FLY DAN SELEPAS FLY-Apa perlu buat

• Check condition batteri Li-Po dan TX Batteri
• set all swicth default
• Check condition HELI especialy Skru setiap kali sebelum dan selepas Fly
• Bawa HELI tempat Launch baru buat connection bagi mengelakkan gyro salah Tafsir semasa initalize
• Peka dengan keadaan sekeliling
• Fly bila keadaan selamat

Terima kasih to my friend iaitu (wanchartsailerman)kerana menyumbangkan ilmu ilmu yang complete

TIP sebelum fly

*on radio pastikan suis pada kedudukan yang betul

*Pas2 bla cucuk bateri,biar gyro baca dlu

*Jgn trus sentuh tkut gyro x lock tail servo

*Bla dah cucuk bateri n smua blh bca bru lah tekan suiz trotle hold ke atas utk nak cek servo

  Maksud trotle hold tu smua prgerakan jln kecuali mtor je yg x pusing

*Pas2 trotle hold pda radio utk tgk semua servo brfgsi

*Lg 1,klu blh kna letak alarm pada heli,dia detect bla bateri kurang, Alarm tu dia akn bunyi,,,kita sempat la nak landing       

  Pas2 dah blh fly la

Tip Keselamatan

Kna on radio dlu bru cucuk bateri (LIPO)

Bla dah slesai (habis main)kna cabut bateri dlu sblum off radio

Paling pntg yg ni kna ingt

Jgn sesekali off radio dlu klu x nak tgk heli trbg sndiri

Itu smua basic yg kna ada pd pilot 

Tip mekanikal

*Logtite tu pntg jgk

*Stiap skru yg nak pasang kna letak logtite ckit

*Heli mmg vibrate kuat

Tip Rutin harian sebelum fly dan selepas Fly

*Klu blh kna cek la sblm naik

*Ketat2 kan skru2 yg ada

*Slalu lap la heli tu sb time kita lap kita akn dpt perasan kot2 ada wayar yg nak trcabut ataupun sbgainya

*Hobi ni mmg kna teliti btl2 ,Bkn mainan.

Tip LIPO tahan lama

*Pas2 nak jangka hayat bateri kita blh gna lama

*Jgn cas n biar  :- Cntohnya klu nak fly hr ni prlu la cas smlm

*Jgn cas n biar 2 3 hr bru nak fly Bateri cpt rosak

* Fungsi Lipo warning alarm ,Dpt jaga bateri jgk spaya kita x main smpai dia low voltage sgt

Tip step by step terbang heli

*Klu bro x brapa yakin.pasang je bebola pingpong tu

*Jgn trus naik tggi

*Klu blh bljar hover dlu utk biasakn diri dgn heli ,Kos x bnyk sgt klu jatuh

  Slalunya mmg mcm tu la

*Fly takat yg mampu

Fungsi suiz trainer

*Mmg jimat kos

*Suiz tu utk main 2 radio

*Mksdnya sifu pgg 1 radio kita pgg 1 radio :-Cnth tgh fly n kita x dpt cntrol.sifu akn cntrol

  Tp kna ada wayar utk join radio ke radio la

fungsi swicth gear /gyro kat tepi chanel 5  dan DR tu smua suiz tolak ke depan

Klu D/R tu atas setting,ada yg nak main slow n laju

CH.6, VR dan HO-Pit .Yg tu biar dia dok pd VR atau tengah

Soalan Keselamatan

Selalu nya pernah berlaku tak kalau cucuk LIPO pada heli,blade terus berputar dan tercabut?

Bt msa skrg mmg x da msalah lg la

X prnh plk mcm tu

Slalunya esc akn bunyi warning klu trotle kita x trun bg hbis

Esc x kan bca klu trotle x trun hbs

Dia x kan detect klu trotle x trun hbs

Klu bab pusing sndr pun x kan brlaku

Esc dia ada safety jgk

Klu kunci ketat slalunya x da msalah ttg blade tu

BLADE TRACKING= nampak kipas heli berlapis  apabila di spool,nak setel                    ni tukar fathering shaft dan main blade dulu.
