It is one of the fascinating and worthwhile experiences when flying your RC helicopter. With time, the Helicopter starts to slow. This is where you will notice that the battery life seems to last for a few minutes. Aside from that, you might come across an irritating spring that keeps the throttle level down.
RC Helicopter Parts
At this point, it will be hard to hover the RC Helicopter. The seminar problems can only be curved by following several steps. The process will drastically improve the performance of your Heli by 90%. Therefore, you need to keep an eye on the following RC Helicopter parts.
The battery of your bird might malfunction without your general consent. If you haven’t yet crashed your RC Helicopter and every part is effective, then the RC Helicopter battery might be empty. They are lots of them in the market hence varying from one model to the next. Note that RC Helicopter comes with the limited flight time. Some will offer you with 6 minutes while others with up to 36 minutes of flight time. In all, the battery of your RC needs to be recharged.
Types of RC Battery
1. Nickel Cadmium (NiCad) Batteries
They have been in the RC industry for almost a decade. In fact, they were the only option for different types of RC models. They have been outshined by other advanced batteries but they are still in the market.
- Provide high-currents or low volt of internal resistance
- Presents low self-discharge time
- It is not affected by low temperature than other RC batteries
- It is quite heavy than other models
- Appears to suffer from voltage-depression or memory
- It is not an environmental firmly battery
Memory is an accurate word that briefly affects this kind of battery. It can also be called as a voltage-depression. This is where the user contrary charges the battery on a partial basis. Over time, it might seem to lose its capacity. To recover from this, you need to recycle bypassing the battery through different series of recharge and discharge operations. Above all, the NiCad’s batteries are still used for both receivers and transmitters.
2. Nickel Metal Hydride (NiMH) Battery
They seem to have dominated the transmitter and receiver industry packs. The current version is far more advanced than the previous one. This allows you to achieve the best practical solution in one application.
- Provide the highest capacity of AA cells of up to 2700mAH
- You won’t experience any memory effects
- It is quite environmentally friendly
- The high level of capacity battery can be difficult to understand
- Have high chances of self-discharge than other models
The NiCad batteries can be used once you get them out of the box. But you need to have a forming charge NiMH for you to have the maximum speed that you want.
Note that the forming charge can’t be done more than ten-hour charging rate. Precaution must be followed when using the hi-capacity NiMH battery thus over 1650mAH. Reason: they can be easily damaged when charged on a high level of current.
3. The Lithium Polymer (Lipo) Batteries
Introduction of Lipo batteries has drastically changed the RC industry in a good way. The current RC models offer super speed performance. Not to mention they are designed to endure the high internal combustion.
- Offers great power supply and uneven weight ratio
- Provides very minimal self-discharge
- It is less affected by low temperature
- Very prone to fire risk
- Can malfunction due to regular over-charging
You are advised to be very keen when dealing with Lipo battery. If misused or abused in any other way, they might represent a sizable danger. Remember not to overcharge the battery for long hours. It is advised to always place them in a fireproof box or a good protection bag to avoid any sudden injuries. If it is damaged in any way, don’t use it.
4. The Lithium Ion Phosphate (LiFePO4) Battery
It is perhaps the ideal battery technology in the market today. Even if it happens to explode into flames, it appears to emit environmental friendly gas.
- Offer adequate amount of power
- Comes with very low self-discharge
- Can easily be used by the RC Gear without the help of a regulator
- There is an only a limited range of battery available in the market
- Comes with odd sizes such as AA, C, and D
The LiFePO4 seems to offer zero problems and it’s quite cheaper and medium-sized. The good thing about this battery is that it comes with superior thermal and chemical stability. This allows it to offer a high level of safety characteristics.
RC Helicopter Motors Types
I can typically call them the beating hearts of any moving helicopter. It assists the Helicopter by providing the exact speed and movement for it to fly effectively. You will always find the brushed RC helicopter and brushless RC one. If you are not sure of what type of rotor you want, follow along.
So, What’s the Difference?
To spare you from difficult mechanical detail, the brushless motor is quite higher when it comes to performance. They don’t use the brush tools when in motion thus converting electricity into motion. The reduction of friction will be felt within the motor making it be more effective.
Note that uses less energy when in motion. That is why they give you a higher speed rate that you want. Brushless motor will always be technically better.
When it comes to a brushed motor they are typically effective by about 70 to 80%. Comes with two wire control units as well as replicable brushes for durability.
It is quite simple to control just like the brushless motor. But note that you have to regularly check the brushed motor once in a while. When at higher speed, the given brush friction increases hence reducing the level of torque.
In all the only difference is this motor uses the so-called “brushes” when converting electricity into motion.
Every part matters when it comes to choosing your ideal RC. But the type of battery and RC motor is what will control the entire Helicopter. Therefore, consider reading the above-informed detail that will allow you to choose the type of battery charger and the motor that you desire.
