Fix and Repair Your RC Toys By Yourselves

Courtesy of
RC Toys are vulnerable and may easily damage, especially the toy-grade kind. The best that any of us can do is to get minimal details in respect of how to repair our remote controlled toys. It's possible for warranty reasons you can speak to your toy producer for a replacement unit. They may agree to replace all those components that damage or wear out easily. If above solution is not applicable to you anymore, the following ways can be doable just before you finally make a decision to throw your toy in garbage. Read on to know how to fix and repair your RC Toys.

The very first you're able to do would be to attempt changing the set of batteries and make sure that the RC and its controller operating effectively. When you are certain that your transmitter is malfunctioning, you can attempt acquiring for another identical RC toy at your local store. Their controllers will usually compatible with your RC toy once they are utilizing the same frequency.

Find out if some unusual object like water, dirt, or mud can be found in your toy by removing the casing apart. If you notice some dirty part, try cleaning it by using a canned air to blow the dust off away very carefully. It's also possible to properly wipe off some water, dust and dirt with a microfiber cloth. On the other hand, when there is too much water, you can attempt drying it off on a sunny day or make use of a hair dryer.

When the actions previously mentioned still fail to work out, you can attempt seek out some loose electrical wiring, damaged gears or parts. Maybe you can search with a magnifying glass to view loose components and repairing them with a tape or glue.

If each of the techniques earlier mentioned isn't working and discovered your RC's inner parts beyond repaired, however the body still looking great, you can opt to upgrading your toy with a hobby-grade parts. This last step can be a little more expensive. On the other hand, if you don't have any understanding of these possibilities, it would be easier for you to get a brand new RC toy. You might need to choose a more appeal design on this occasion which has spare parts available, because you will spend less in the long term.

I will try to write down the way to repair several brand of RC Toys in my future articles.

Parrot AR.Drone Quadricopter : A New Flying Experience

Courtesy of
The AR.Drone quadricopter or quadrocopter is a revolutionary product merging the very best of several worlds, such as video gaming, modeling, and augmented reality. The Parrot produced quadricopter is remote-controlled by an iPhone4, iPhone3GS, iPad or iPod Touch 4th Generation and equipped with several sensors, such as a vertical camera, front camera, and an ultrasound altimeter. The best thing is it could also be used in video gaming, for instance AR.FlyingAce, a battle between two AR.Drones. Read more our Parrot AR.Drone review.

You can get these in the package; the AR. Drone, four types of adapter, 1,000 mAh Li-Po battery, 3 cells Li-Po balancing charger, indoor and outdoor hull, sticker for outdoor hull and a manual (see above pictures for detail).

How To Fly AR.Drone

To fly this thing, you need to have the Apple products like iPad, iPod or iPhone, and then you need to download the Free Flight software to control the AR. Drone at, but you need to register first. You can alter the pre-programmed command by using this software if you want to have a different flying experience.

Auto-Flight Features

The sophisticated gadget comes with several best features. The one that I like is the auto flight functions. When you lose contact with it, the automatic flight will automatically get into action, where it will hovering stationary until the battery depleted, and then decide by its own to land it if the entire battery has been used. You can also turn on the auto-flight mode if you want to do something for a while.

The computer will do everything for you, you only need to tell what to do. For instance take-off is easy, just press auto take-off button and set the altitude you want the toy to hover. It will stay that way until you take control and give another command.

Because everything is pre-programmed within its processor, you can’t fly the toy pass the given flight parameter. Therefore, you can surely fly it even if you are a newbie, but if you want to learn everything related to this RC Toy, feel free to visit its site at


AR.Drone equipped with two cameras (front and vertical/down), very useful when you want to see what the toy sees. Front camera refresh rate is a bit slower than down camera. Down camera is needed in auto-flight mode. Unfortunately, this RC helicopter gives no video recording features.


The battery will last for approximately 12 minutes and full charging takes about 90 minutes. I would recommend – for longer battery’s life - to stop using the toy when the power in the battery is only around 20%.

How to Repair AR.Drone

The durability of AR.Drone is good, the carbon fiber frame and polypropylene foam body give a good protection to the electronic component within. In case of any crash happens, you can learn to repair it by yourself from seeing this video. But you need to have a spare set of gear, blade and the AR-Drone tool.

Some safety features also given to it, such as it will turn off when some sort of excessive pressure given to the propellers. This will prevent the motor getting burnt.

When seeing the capability such as the auto-flight, newbie-friendly functions, the built-in camera, the durability and stability, you can expect to get this at more than $500, but the AR.Drone price is much cheaper only around $300.

If you like to own this awesome toy after reading this Parrot AR.Drone review, you can purchase it at AR. Drone shop for discounted price. For more gaming experience, you can visit the Apples iTunes stores and find some games for the toy.

Everything We Should Know About Li-Po Battery

Electric RC Toys has becoming more popular – especially the airborne type, since Li-Po battery invented. It has more advanced benefits which are helping to popularize the electric toys. One of them is the light-weight benefit, which is very suitable in flying remote controlled toys, like helicopter or airplane. The Lithium-ion Polymer battery can be obtained in the market starting at around 1996.

Li-Po is using dry electrolyte that looks like a thin plastic film, that is why this battery could be shaped very thin and light-weight but able to hold more power. Compare to the Lithium-ion (Li-ion) battery which is using a liquid electrolyte.

New Type of Li-Po Battery

Since 2009, the new type of Lithium-Polymer battery has been introduced, where it is using a gelled electrolyte. Some people call it a hybrid Li-Po battery. This new battery type has less possibility to leak, but still keeps its flammable potential, to burn or explode when overcharged or other mishandling act.
The hybrid Li-Po battery has an interesting trait, its ion exchange rate tend to get more efficient when it gets warmed up.

Li-Po Battery Ratings

If you read the label on the battery, you can see some sorts of technical term, which are the battery specifications. Read on for more information what to know when you want to buy a LiPo battery.

a. Voltage
Each cell in Li-Po battery contain 3.7 volts, compare to NiMH or NiCad which contain only 1.2 volts per cell. Sometimes you can find the battery with 1S or 2S written on the label, that means the battery contain 1 cell or 2 cells (S stands for Series), respectively. More cells means more power, for instance 10S Li-Po battery contain 10 battery cells with the total power 37 volts.

You will also find a label like 4S2P (P stands for Packs), that means the battery contains 2 packs of 4 series of cell. This type of battery will hold more capacity.
Please be careful in choosing your battery, read your rc toys manual, which kind of battery they need to operate properly. Don’t try to change it unless you know exactly what to do next.

b. Capacity
Capacity describes with a milliamp hours (mAh) unit, which means the power contains in the battery. In practical it means how much load can be given to make the battery fully discharge in 1 hour. For example; 1,000 mAh battery means it will be fully discharge in 1 hour if the load given 1,000 milliamps (1 A), that also means it will discharge in 15 minutes if the load 4,000 milliamps (4 A) or 4 minutes in 15,000 milliamps, and so on.

Therefore, if you want to play longer with your RC toys, please find the battery with bigger mAh. You can change without reading your manual, but the problem is when you want a bigger capacity, the battery will become heavier. Consider this when you want to get higher battery capacity, especially when you intend to use it on your airborne rc toys.

c. Discharge Rate
Discharge rate is the term to inform you how fast the battery discharged safely. You can find the discharge rate describes in C unit. If you see the 20C, it means the battery can be safely discharged 20 times more than the capacity, 10C means 10 times and so on.

You can calculate it by yourself by using this formula. Divide the capacity to 60, to get the capacity in minutes, and then multiply it to the C rating. Then divide the capacity with the results.

For example, 20C rating on 2,000 mAh battery, that means you can give 20 times more load equals to 40,000 miliamps and that would exhaust the battery within 3 minutes. Let’s see the formula : 2,000/60=33.3x20=666 mAh per minute; then to get the time divide the capacity to the result, which is 2,000/666=3.03 minutes.

Several Li-Po batteries give different discharge rating, that is Continuous and Burst. Continuous is the normal discharge rate (normal usage) and Burst means the battery discharge rate when under short burst of increase power. Example of this rating is 10C Continuous /20C Burst.

You could expect that more C rating means more expensive the battery will be. Purchase the largest C rating if you can afford it. As a guidance, for normal flying rc it is enough to get 20C-25C, for larger airborne supply it with 25C-30C, and if you are an aggressive player please use 35C-45C.

Li-Po Battery Pros and Cons

RC Li-Po Battery Advantages
  • Light-weight and can be built in almost any shape and size
  • High discharge rates
  • Hold bigger capacity compare to other battery type with the same size
RC Li-Po Battery Disadvantages
  • Volatile and easily burn or explode when mishandle (i.e. overcharge, punctured or shorted)
  • An expensive battery than another type
  • The battery life-span is 300-400 charge cycles, or even less if not cared for in the right way
  • Battery life-span depend upon several things such as storage, charge and discharge

How to Handle Li-Po Battery

  • Keep your battery’s temperature around 50 - 60°C when in use or in storage, hotter battery will shorten its life span. If you find out that the battery reach above temperature everytime you are using it, then you should buy another battery with higher discharge rate
  • Prevent over discharge; never push your battery to use more than 80% of its capacity. For instance stop using your RC toys when you have used 1,600 mAh when you are using 2,000 mAh type of battery.
  • Never charge your battery more than its capacity, for example 2,000 mAh battery should charge it at 2,000 mA or 2A current (or also known as 1C). But some batteries could stand to 2C or 3C charging rate, that means you can charge it twice or thrice its capacity.
  • Inadequate charge balancing, find a good charger with charge balancing features or a single cell in your battery would possibly damage by over discharge when other cells still not fully charged.

I hope this article could gives a better picture about RC Li-Po battery, but if you want to know more about it, please read this resource. You can also visit my previous article about rechargeable battery's charger.

Different Types of RC Helicopter Blade

If you are an enthusiast in remote-controlled toys especially rc helicopter, you should have some experiences related to blades and problems occasionally caused by them. In this article, I would like to write about rc helicopter blades type. RC helicopter blades take a vital role, without it you can’t expect the toys would fly.

What are RC Helicopter Blades?

RC Helicopter Blades are plates attached to a rotor, giving a thrust power that lifts the chopper upwards (main rotor blade)or tail balancing (tail blade).

Types of Blade

Good-quality blades should be durable, just in case you or your kids still learn to fly the toys. Blade is a part in rc helicopter that will likely bump into things and have a high risk of becoming damaged. You should also pick not too sharp blades, since you don't want to ruin everything inside your house, whenever you fly it inside your house or you purchase the indoor types of rc helicopter.

RC Helicopter blade type available in the market these days are:
  • Wood
  • Metal
  • Fiber Glass
  • Carbon Fiber
Wood is the cheapest but lack in maneuver ability, even you can try to build one if you like to do it yourself. Metal blade is heavy but more durable and cost more than wood. Fiber glass is more durable but heavier than wood, besides it is also lack of maneuver ability because of its weight. Carbon Fiber is the best of all because it is light, durable and suitable for expert flyer. You can easily do some acrobatic stunts with it, but the price is also the most expensive compare to another blade type.

You should also seek a rounded edges one. Rounded edge blade is not merely aerodynamic, but will also prevent it from cutting yourself or your kid.

If you are new and still learning to fly your chopper, you can choose the cheapest one, for example wood blade or fiber glass. You can change later if you are becoming expert in flying your rc helicopter.

Everything You Should Know About Rechargeable Battery Charger

In portable world like remote controlled toys, using rechargeable battery is a must. You can't operate your beloved toys without it. My previous article already writes several types of batteries known in rc toys’ world, then the next related article will be about its charger. What you should know about rechargeable battery charger?

There are three types of rechargeable battery charger available.

1. Slow Charger

By using slow charger aka normal charger or overnight charger, you will expect to fully charge your battery in more than 14 hours. Slow charger is suitable for NiCd batteries only and is the cheapest type than another type. It has no full charge detection, but as long as using the right type of charger with suitable battery’s mAh and you don’t charge your battery for more than a day after fully charged, it is still considered safe, but better to unplug the charger right after reach its full charging capacity.

You should note the battery’s mAh and choose the suitable slow charger for it, because when small mAh battery charge with a bigger one, will heat up the battery at 70% charging capacity and if you keep charging it, this heat will damaging your battery. On the contrary if you charge using smaller mAh charger to a bigger mAh battery, the battery will not performed well and if you continue to undercharge the battery, eventually it will affect its fully charge capacity or known as memory effect.

2. Quick Charger

Quick charger’s - or more popular as rapid charger - capability and price is in between of slow charger and fast charger. Battery will fully charge in about 3-6 hours. Good charger should have charging control, which will terminate the process when the battery is full, and this good quality type will keep the battery last longer.

3. Fast Charger

This charger is the most expensive than another, because most of the type available has more sophisticated charge control and also bigger power supply. Nickel-based battery will fully charge in about 1 hour but Lithium-based battery will not affected very much because this type of battery has slower mechanism in absorbing energy. When fully charge, charger will switch to trickle charge, that means the battery is safe from overcharge, and the current only to compensate the self-discharge process. However it is still unsafe to leave the battery charge in days.

The first charger suitable for NiCd battery only and NiCd battery manufacturer recommend to slow charge the new NiCd battery for about 24 hours right before used.

Second and third type of charger above are suitable for NiCd, NiMH and Lithium-based battery, but you should not interchange the battery with another charger.

Charger designed for NiCd can’t be used to charged NiMH, it will overcharge the battery, but NiMH charger can be safely use to charge NiCd battery.

Battery Type for Remote Controlled Toys

Your RC toys life depends very much on your battery. Each remote controlled toy is using different type of battery. I will try to describe all type of battery available now, and my next article will discuss on how to handling them for longer life-span.

Each RC Battery type has its own characteristics, such as voltages, chemical compositions, life-cycle and so on. Technology on batteries has evolved so much focusing on the main principle, which is to find a media that keep the energy as long as it can, safe for use and also for environment and has longer life-cycle.

So now we have better type of rechargeable batteries that we can use, especially for our beloved RC Model, but still every type has its own pros and cons.

Nickel Cadmium (NiCad or ni-Cd)

Some RC Car models are using Ni-Cd battery, each of them has 1.2V voltage. This kind of battery need to discharge fully before you wants to charge it, because it is said that the battery won’t be fully charged as a result. It's called memory-effect. Please purchase a battery discharger if you want to keep your battery longer.

Ni-Cd usually sold in package containing several soldered batteries - two or more, to form the voltage required by the application. Self discharge rate is about 10% per month.

Nickel Metal Hydride (NiMH)

NiMH is the next generation of rechargeable battery, which comes with the same size and voltage like Ni-Cd, also sold in packaged according to the voltage they need to form. NiMH has more advantages than Ni-Cd as it has longer life cycle and safer for environment.

Disadvantage is its high self-discharge rate at about 30% per month, higher than Ni-Cd battery. But there are also available Low Self Discharge NiMH - introduced at November 2005 - which is having the lowest self discharge rate, that is 1,25% per month.

Lithium-ion Polymer (LiPo, Li-Poly, PLI, LiP, LIP, Li-Pol)

LiPo is the new technology of Lithium ion cells and some RC toys has been using it because of its light-weight reasons. Li-Po battery can be stored for about 1-2 months without losing charge significantly. But if you intend to keep it longer better discharge it to 40% of full charge capacity. I read somewhere that you can refrigerate it, but not freezing it.

Please be careful when charging Li-Po battery, as it becomes hazardous when you overcharged. This can cause explosion or fire. That is why some good charger manufacturer will stop charging process at about 90 minutes to prevent this thing.

Lithium-ion Battery (Li-on or LIB)

Lithium-ion has been widely used in consumer electronic, such as laptop, cell phone and in RC Toys as well. This battery has some advantages, light-weight, no memory effect, self discharge only about 5-10% per month, and a lot safer for environment. Disadvantages of Li-on is in it's cell life, cell's capacity reduce over time, because each charging form deposits inside  the electrolyte that inhibit ion transport.

Be careful when charge the unit, overheat or overcharge can lead to combustion. But some battery manufacturer already put fail-safe circuitry, that will shut down the battery when the voltage outside of the safe range (3 - 4.2V).
