If you have been driving a remote control helicopter for a while, then it is better to understand the basic working principles of your aircraft.By doing so, you can better choose which process works best for your needs and budget.Some of them are precisely reduced versions or replicas of real things.Therefore, they may be more difficult to handle than real-life machines.There are many moving parts in small replicas, because of this;The cost can be very high for ordinary pilots.Different engines have different models and designs.The cost of maintaining these engines can be quite high, so it's better to know how they work so that you can best choose which RC helicopter is right for you.For most traditional enthusiasts, Nitro and gas-powered engines are the only option because they are traditionally the most powerful.However, with the renewal and improvement of motor and micro-electronic technology, this has become the past.Today, a RC helicopter is powered by a lithium battery.Their engines are not only as powerful as engines powered by Nitro or gas, but they also have an added advantage that the cost of buying, maintaining and operating is much lower.Because they are less noisy, the electric version can be used at home or comfortably in the backyard.They are also large in size up to 80 inch.You can choose between aircraft with fixed spacing and collective spacing.The Nitro-powered RC helicopter is the most popular choice for amateurs.They are very durable and cost-effective compared to other fuel-powered birds.Compared to its size, the Nitro engine generates a lot of power and uses a glow plug instead of a starter plug.Be sure to read carefully how to maintain and adjust the Nitro engine.In order to make the most of your bird, you must also make sure that you are familiar with fuel, silencers, and exhaust systems.A nitro-powered aircraft is much more noisy than its electric aircraft and is only suitable for outdoor use.For some pilots, this huge noise can remind people of the noise from helicopters in real life.Thanks to its powerful engine, it is easy to achieve higher speeds and longer flight times compared to electric birds.The cost of fuel is also very high because the Nitro is classified as a hazardous substance.The Nitro power engine is very powerful and almost indestructible.RC helicopters that maintain electric and Nitro power require a lot of dedication as they need to be repaired after each flight.Regular maintenance is essential to keep the aircraft running over the next few years, and you can do this easily by ensuring that all components remain well lubricated.When choosing between the two, it is difficult to judge which of the two is better because they both have their own pros and cons.Therefore, decide which option is appropriate for your current situation and choose the one that best meets your needs without affecting your budget
