What is the memory effect?

Rechargeable batteries do actually have what is commonly referred to as a memory. If a battery is consistently used at only partial capacity, the crystal structure of the inner chemicals will physically change, altering the capabilities of the battery. In essence, if you consistently use 25% of a batteries charge, it will change to only offer you 25% of its original charge.

For radio control batteries used in cars, running your vehicle until the charge is used up may not be so difficult. But if you use these radio control batteries in airplanes, draining the battery all the way down in your plane can obviously be disastrous.

Finally, lithium polymer batteries like those above never develop the dreaded memory effect and coupled with their light weight they are perhaps the ideal RC batteries availalbe today!

Build a remote control helicopter

1.First, you need to decide on which model helicopter you are interested in. Once you have it built youll be ready to start flying no matter which one you decide to build, and for the most part the skill level is the same, so why not pick a chopper that appeals to you?

2.The best way to decide which RC helicopter to buy is to have a look at the different choppers that are available. Read reviews on the different models and types to discover which fly the best and which fly the worst, find out what others like or dislike about certain models. After that, youll be able to make an informed decision and you wont be wondering if you made the right choice.

3.Purchasing your remote control helicopter is just the beginning. Then you will also need to purchase the various parts that you will need like an engine to make it run, the gyro that will control the rotor, the servos and radio controls which is how you will talk to your RC helicopter. The servo is installed in the helicopter and it is where the signals from the remotes are transmitted to.

4.Next, you need to be sure that you have all the tools that you will need to build your helicopter. Nut drivers, ball drivers, screw drivers, pliers, wrenches, fuel filters, glow plugs, pitch gauge, all kinds of nuts and bolts. No matter which kit you buy there always seems to be a screw or two missing, or you loose one while doing the assembly, oh yes, and dont forget those repairs youll have to make after a crash. And you will crash everybody does at first. In fact, its half the fun of learning to fly.

After youve built your remotecontrol helicopter, its almost time to take it for a test flight. Remember, anything that turns must be balanced, your end points need to be equal, and all the bolts need to be tight. If you have a friend thats an experienced RC helicopter pilot, ask them to look over your project to make sure youve got it all right.

How fly rc Helicopter

The tail rotor blades rotate to exert force in a sideways direction that keeps this from happening. How does the tail rotor know when to exert this force and how much to exert? Thats where the gyro comes in.

The gyro takes feedback from how the pilot is controlling the helicopter and how the helicopter is turning. If it determines the sideways spinning motion occurring is not being called for by the pilot, the gyro employs the tail rotor to react to keep the helicopter in the desired position.

Now that you have the basics of radio control helicopter models flight, youll know part what youre looking at when you select your model. Youll also know the basics of movement, which will go a long way in learning to control your helicopter.

Using Lithium Polymer Batteries in Your RC Helicopter

Introduction to Using Lithium Polymer Batteries in Your RC Helicopter

Lithium Polymer batteries are currently considered the best electric power source available for use in electric rc helicopter kits. The reason for this is that lithium battery packs are significantly lighter than NiMH or NiCD packs, and have higher capacity for the same size. Over the last five years they have worked their way into the hobby market, and in addition to being used in electric rc helicopter kits they are also common in rc boats, cars, and airplanes. Their low weight and high capacity make them ideal for long flight times, while also providing more power.


Understanding Lithium Polymer Battery Specifications:


Lithium Batteries are also know as LiPo, Li-Po, LiPoly, and Li-Poly. What do all the lithium battery specifications mean? The values that are the most important are:

Pack voltage (depends on cell count; each cell is 3.7 V)


Capacity (mAh)


"C" rating (describes the rate at which power can be drawn from the battery)

Lipo Battery Cell Voltage


The nominal voltage of each cell in the pack is 3.7V, but this can go down to 3.3V during discharge, and up to 4.2V when fully charged. A battery pack is composed of two or more cells put together in series for increased voltage, or in parallel for increased capacity. A 2 pack with 2 cells in series would be rated at 7.4V (2x 3.7V).


The battery pack configuration is denoted by the number of cells in series and the number of cells in parallel. A 3s2p pack would have three cells in series, and 2 cells in parallel, using a total of 6 (3×2) cells. A 4000mAh 3s2p pack would have a capacity of 4000mAh (2 x 2000mAh), and a voltage of 11.1V (3 x 3.7V). It would internally consist of six 3.7V 2000mAh lithium polymer cells. The cells would be doubled up (the 2p part of 3s2p) to get 4000mAh, and there would be three in series (the 3s part of 3s2p) to get 11.1V (3 x 3.7V).


The "C" Rating


The "C" rating describes how quickly a battery can be discharged. A 2000mAh LiPo battery with a "C" rating of 1C continuous would mean it should not be discharged any faster than 2000mA or 2A, which would take one hour. A 2000mAh pack rated for 12C continuous would be able to discharge at 12 times its capacity (12 x 2000mA = 24000mA or 24A) at which rate it would discharge in 1/12th of an hour. Using a pack with a higher C rating than you require will leave some room for safety, and extend the life of your battery.


Continuous Current:


If you know how much continuous current will be drawn and the capacity of the pack you want to use, you can easily determine what C rating you require. If you are drawing 5A from a 1320mAh pack, simply take the current and divide by the capacity: 5A = 5000mA, 5000mA / 1320mAh = 3.8C.


Burst Current:


LiPo batteries are also given a C rating in terms of burst, which is how quickly the battery is able to discharge for a short time. A burst rating of 20C would mean a 2000mAh battery could supply 20 x 2000mA = 40000mA or 40A for a few seconds.


Selecting the Best LiPo Battery for Your RC Helicopter


To select a battery for your rc helicopter, you first need to know what voltage you require and how much current you will be drawing continuously.

If the motor in your rc helicopter is rated to work with 11.1V, you would need a 3 cell battery.


If you need to draw 20A, and you would like your rc helicopter to have a 10 minute (1/6th of an hour = 6C) flight, you would need a battery with 20A / 6 = 3.3A = 3300mAh.


This means you would need to put a 3s 3300mAh battery with a C rating of 6 or higher in your rc helicopter.


Thunder Power RC has a LiPo battery for almost any electric RC helicopter. Always Remember These LiPo Safety Instructions

Remove the battery pack from your rc helicopter before charging.


Only use chargers designed to work properly with lithium polymer batteries.


Always place your LiPo on a fire-proof surface while charging or use a LipoSack.


Never leave your battery unattended while it is charging.


Never charge a lithium battery if it is below 3.0V per cell.


Never charge a lithium battery that is puffed up, or damaged in any way.

1. Check the ball links for looseness or slop. They'll wear out over time and if they're not on tight, they can pop off during flight and cause a crash.


2. Check all mission critical nuts and bolts to make sure they're on tight. Excessive vibration can cause them to back off or come loose, even if you've used thread lock.


3. Inspect the wiring. Visually check the wiring for damage and ensure that there are no breaks or cuts and that the servo plugs are securely plugged into the receiver. If you have any servo wire extensions, make sure the connections are solid.


4. Test your radio. If it's your first flight of the day do a range check and make sure there's no interference nearby and that the throttle hold functions are working properly. It would also be a good idea to quickly check your trims to be sure you haven't bumped one out of position.


5. Check that everything's working properly and moving as it should. Check the throw direction for all pushrods and servos and make sure the swashplate is moving as it should. It's very easy forget to change a radio setting back to normal when bench testing.


6. Check your tail belt tension. A loose belt can cause slippage and loss of tail control. A belt that's too tight will put unnecessary wear on your motor and other tail drive system parts potentially causing a problem. Squeeze it with your fingers to ensure it's tight enough, but not too tight.


7. Make sure everything's mounted securely. Make sure that all parts that are mounted with pads, Velcro, zip ties or double sided tape are attached securely.


8. Check your batteries. Make sure your batteries are all fully charged and secured properly. If possible, test them with a volt meter under load. Also visually inspect them for damage or potential causes of short circuits.


9. Inspect your blades and flybar. Visually check that they're aligned properly and that they're on securely. Move them a little to make sure the dampers aren't broken or worn out.
