When Choosing Your First RC Electric Plane. Points To Consider

Electric Radio Controlled Plane. How To Choose The Right RC Electric Model Airplane For You.

By Carl Baer

 Before I begin, you should probably know that this might not answer your question of which electric radio controlled planes will be a best fit for you. The reason…Everyone is different, hasChoosing an electric radio controlled plane seems to be the hot topic of the century. I am asked this question more often than any other one. It is also the most controversial. No one can seem to agree on what is the best first electric radio controlled plane to buy.

Ok. let’s get right into it…

First things first. If this is your first electric radio controlled plane, there are some time honored factors to consider.

1. Wind – You may be thinking that this is an obvious one. Why would I fly in wind? The question really is, how much wind is safe for an electric rc airplane? Remember, we are dealing with smaller aircraft that can only handle a Maximum of 5mph winds (That is THE MAX).

2. Orientation – This is so often overlooked by every beginner and takes some time to get used to. Your perception of up and down and left and right can easily be impaired when your plane is up in the air. Instead of practicing in the air, try this technique. Get a cheap rc car that has throttle and steering controls. Steer the car in the same pattern that you will fly in (a U shape is traditional). Remember, the steering will be reversed when the car is coming at you, this is where you need to become proficient.

3. Speed - It is imperative that you learn to control your speed. A common beginner mistake is to keep the throttle at full speed and forget to back down once the plane is in the air. Your plane will fly fine even with less than half throttle input from your transmitter. When landing, remember that you are going to be using even less power. Almost idling the motor will be enough to land.

4. Altitude - Most beginners believe that they need to keep their electric radio controlled plane low so that they can see it better. This is exactly what not to do. Most crashes happen because there is no room to make corrections. A good rule of thumb is to be at about 100 feet.

5. Over Control - Every beginner will do this, it just is part of learning how to “feel” the controls on the transmitter. Remember, you want to use slow movements to control your electric planes movements. It will take some getting used to, but you will get it, just be patient.

6. Preflight Check - What is this you may be wondering? It is an essential step. Follow it and you will always eliminate those forgetful steps (like forgetting to make sure your battery is charged fully). Make sure your plane is ready for the air on the ground, not in the air when it is too late.

If you are a beginner you will be looking at a LOT of choices for your first plane. In fact, because electric rc planes have become so popular, there are more choices than you can shake a stick at.

Let’s narrow it down really fast.

1. Get an rc electric plane that has a high wing.

Forget about buying a flashy low wing sporty electric radio controlled plane. You will not be able to control it, and it will not be forgiving at all. Do yourself a favor and get a high wing electric for your first model.

Here are some of the most durable and most popular models for beginners…

  •  GWS Slow Stick. Hands down this is one of the better beginner electric airplanes out there. If you start with this rc plane, you can teach yourself to fly (you will crash though, it happens to all beginners).
  • Slow-V from Parkzone. Best flown in still to under 5 mph breeze. This is the best choice for people who only have a small space to fly or who have an indoor place to fly (you want this as a beginner).
  • T-Hawk - RTF – Comes with extra wing, tail and battery.
    Flies well and stands up to hard landings (a must for beginner flyers).
  • Firebird Freedom - RTF Electric. This is a three channel plane that incorporates electronic anti-crash technology which actively monitors the plane’s orientation. (It corrects itself if you do something wrong, which all beginners will:).

2. For the least amount of headaches, start with an RTF (ready to fly).

The GWS Slow Stick for instance includes the following accessories (as do many RTF’s).

  • Receiver – This device responds to the input from your transmitter. For example, if you push a control stick on your transmitter, the receiver picks up this signal, and relays the “command” to the servo that corresponds to the transmitter’s control stick movement.
  • Electronic Speed Control (ESC) – It regulates the speed of the
    electric rc motor by regulating the power to the motor to achieve the desired speed of your electric radio controlled plane (which is relayed from your transmitters throttle stick movements). The ESC also has two other functions- it has two circuits. The first is the LVC (low voltage cutoff) which will cut power to your electric motor and reserve the remaining power for the receiver and servos (so that you can still land your rc airplane). The other function of the ESC is the BEC (the battery elimination circuit supplies power to the receiver and the servos, thus eliminating the need for a separate battery.)
  • Servos – Micro Size. These devices are what move the control surfaces of your rudder, elevator and ailerons (if included). They are connected to the receiver and “mimic” the movement of your transmitters control sticks.
  • Battery – usually comes with a Nickel Metal Hydride (NiMh) 6-cell, 7.2 Volt battery pack. It is fine for starting out, but you will soon find that you need more power and run time.

Note: Buy an extra battery, so when the first one is done you can keep flying.

3. Space…you need to consider how much space you will be flying in.

  • Consider this… If you only have access to a local park, then you need to buy a rc plane that can be flown in that size space.
  • Here is a quick break-down of what you can fly and not fly based on your safe flying area. (These figures are estimates and are appropriate for a beginner, but you should always fly in the biggest open area you can find, with no people nearby of course)…
  • If your flying field (or park) is about the size of 1 football field, (200 x 200 feet) you will need to stick to small Park Flyers. These are lightweight planes that cannot be flown in any wind, and fly very slowly…just the thing for a beginner.
  • If you have a bigger open space, say 600 x 600 feet (the size of 4 or 5 football fields), you can fly bigger and faster electric Park Flyers. These will typically be two pounds or less and fly slower than 40 mph. Usually they will use a Speed 400 or 480 electric brushed motors. You can fly with less throttle (1/2) and this will allow you more time to get used to the airplane.

Any bigger size flying area and you will be fine with whatever size plane you want to try. If you cannot find a place to fly, look up flying clubs in your area, or ask a farmer or rancher if you can fly in one of their pastures. There is always an option if you just look around.

4. Weight. With Electric Radio Controlled Planes, weight will always be a factor. Of course the technology is getting better and lighter batteries are being made that hold more charge and can allow you to fly for longer periods of time. However, when you really get into flying rc planes that are powered by an electric motor, weight will always be a greater factor to consider.

5. Price. You will spend about $200.00 for most everything you will need. This will include the following. (Remember this is based on a RTF kit (that runs from $35 to $55.00), and is essentially the bare bones of what is needed to get into the air and fly.)

  • Transmitter – This is the “box” that you hold and it controls your electric radio controlled plane in the air. Usually you will spend around $60.00 for a decent 4 channel radio. It is all based on your budget. You can easily spend $1000.00 dollars on a top of the line transmitter (most transmitters come with servos, this is standard). Stick with a basic radio to start out, but nothing under 4 channels, otherwise you limit yourself later on with planes that need at least 4 channels to control ailerons, rudder, elevator, flaps, retracts, etc…
  • Crystal – A crystal is a small plug-in transistor that communicates on a certain frequency. Every transmitter has a crystal with a frequency (FM or AM or now GHz). You will need to check what the frequency of your crystal is and order one for the receiver in your electric plane. Cost is about $10.00.
  • Battery Charger - Spend about $45.00 to get a charger that can charge by DC (your cars cell phone charger outlet). This way you can charge while you fly. Get one with peak detection (automatically knows when the battery is charged), the capability of charging NiCd and NiMH batteries, and the ability to charge up to 8 cells  (at least).

Note: Make sure to get some charging leads for your charge so you can charge your specific battery packs. Cost is About $ 6.00.

Well, that is a lot of information and I hope it will help you make an informed decision towards buying your first electric plane. There is certainly a lot more information to each of the categories that I have gone over. But the goal of this article was to get you familiar with the essentials so that you could buy a RTF or ARF (I recommend a RTF to keep costs down) using this as a guide to fit your needs.

I have been flying and building radio controlled airplanes, helicopters, boats and cars for over 20 Years. I have been specifically building and flying electric airplanes for over 10 years. My latest interest is to convert balsa wood kits with gas engines, to models with electric motors. This has been more realistic to do lately because of the huge leap in battery technology and it has been a very fun way to still make balsa kit planes from scratch, but not worry about any gas problems.

What To Choose When Converting RC Gas Engines To Electric Motors.

How To Choose Components For A RC Plane Gas Engine To Electric Conversion.

By Carl Baer

How To Convert RC Gas Engine To Electric Motor Easily.

Converting A Hangar 9 Arrow Gas Engine To An Electric Motor With Li-Po Battery.

What you should consider before converting your rc airplane gas engine to an electric motor system.

With the changes in rc electric motor technology it is possible to fly ANY size model using rc plane electric motors. The biggest leap in making this possible has been two fold. First we have model airplane electric engines that are powerful enough, not to mention much more efficient, that they rival or even surpass gas/slimers/smokers/nitro hogs, or whatever else you may call rc airplane gas engines.

In fact you can expect to see an increase in the performance of a model airplane in several areas. Your take-off is shorter, climb rate will increase and you can now fly in areas that have noise restrictions.

The debate between the benefits of rc plane electric and gas motors are as controversial as those between pc and Mac users. It will continue for as long as they are both in existence.

Some questions you might be asking before you convert your rc model airplane’s gas engine to an rc electric motor…

How long will the battery allow me to fly? With today’s Lithium Battery technology, you can easily expect 10 minute flights, even in bigger aircraft. The days of overheating the batteries and fire hazards are almost non-existent. There are many add on features that you can now purchase that all but eliminate battery hazards. Such as temperature monitors and voltage indicators.

Here are some questions to ask before you start buying any components. These questions will help determine what components to buy.

1. What is the radio control plane that you are wanting to convert? Is it a trainer, sport plane, 3D etc.. This is important because you will need to determine the electric motor based on your models capabilities, and what you want it to do.

Example: Hangar 9 Arrow with a .40 size gas engine.

Would require an electric rc motor equivalent to a AXI 2826/12 External Rotor Brushless.

This motor would allow this model to perform basic aerobatics with its semi-symmetrical wing.

Specs of the Hangar 9 Arrow

You will need these numbers to help determine the motor, battery, and prop requirements.

  • Wingspan: 63 in
  • Overall Length: 52.5 in
  • Wing Area: 710 sq in
  • Flying Weight: 5.7 lb (as a radio controlled gas plane)
  • Engine Size: converting a standard .40 size rc gas engine to an rc electric motor.

Now you need to determine what type of batteries you will need. This is based mostly on your budget and time till land variable. In other words, how long do you want to fly for and still get performance.

The most obvious choice is going to be a Lithium Polymer battery, this is the most advanced battery technology available for rc model airplanes. They are also the most expensive. Other older battery technologies are available, such as, lithium ion and nickel metal hydride. They can do the job, but at a weight cost and flying time consideration. So choose carefully.

In the Arrow Example: We will use a 4200 mAh 11.1V Li-Poly Pack. This was determined based on the flight performance we were after, some aerobatics, but mainly stable easy going flying. Nothing too extreme.

As with any gas rc plane conversion to electric (or any electric radio controlled airplane for that matter), you will have to consider an ESC (electronic speed control). This hooks up to the motor, battery, and receiver. You will need to pick one that can handle the required number of battery packs, servos and have programmable features. This will make life easier for you if you pick one that is feature rich. Of all the components, this is one to spend a little more on. You will be glad you did.

For this example, we used a 40 Amp Brushless Controller with Program features. There are lots of manufacturers of ESC’s so take the time to research them.

Prop Selection is an important consideration. You need to be aware that with an electric conversion there is a possibility that your model plane will not have enough clearance when using an electric motor prop. It may need modifications to the landing gear (making them longer) so that the prop has clearance.

For the Arrow example we used an APC 13×10 propeller. Most electric motors now have a table that you can find on their website that will recommend the propeller range to stay within.

One final consideration with rc gas planes converted to electric. You always need to factor in cooling of the battery pack and esc. In fact many modelers, including myself, put the ESC on the outside of the plane, usually I mount it under the engine on the firewall. You also need to make air vents to cool the battery inside the model. Without this, you run the risk of overheating batteries and ESC’s.

Any RC Gas Engine Can Be Converted To Electric. Is There Any Reason Not To?

Why would you convert Radio Control Gas Plane Engines to Electric RC Motors?

By Carl Baer

Now more than ever it seems that we are entering an era that needs to depend less on fuel burning engines. That even includes radio control airplanes with their nitro-methane gas engines.

Converting RC Gas to electric, components you might need.

Converting RC Gas to electric, components you might need.

How can you ease the burden on gas burning rc engines? Simple, convert your balsa kit, RTF or ARF to an electric engine. In fact, in a lot of areas of the United States it is almost impossible to find a place to fly anything but electric airplanes anymore.

Noise abatement and encroachment on rural areas have really affected the number of places left where you can fly gas engine rc planes. It’s simple, as the population grows, there are fewer places left to fly rc airplanes safely. In fact, most rc clubs are abandoning gas powered model airplanes, and trading in their gas engines for electric power plants. Why? because their “new” neighbors do not want loud gas powered aircraft flying past their homes (even though they were not there first). Instead of closing the club, they are encouraging their members to convert their aircraft to electric powered aircraft. This eliminates most of the noise and allows them to keep flying.

I have given in to the electric era and have been converting most of my rc airplanes to electric motors. This is not to say that I still enjoy the power and thrill of rc gas engines, but it is getting harder to find a place to fly it and not be bothered by residents that think you are encroaching on their peace and quiet. This is not to say that converting rc gas engines to electric is as simple as switching out motors. In fact there is a lot to consider when doing a rc gas engine conversion to rc electric motors.

You have to consider all of the following…

  • C.G. – The center of gravity for your model aircraft has just been greatly changed. All that weight of the metal gas engine needs to be balanced somehow.
  • Flying time - Gone are the days of just filling up the tank and going up again. Now you need to manage battery packs and keep them on a charging cycle and make sure not to over use them.
  • Chargers – Be prepared to learn a lot about chargers (DC for your car), different types of battery packs NiCad, NiMh, Li-ion and Lithium Polymer (the newest and most challenging to charge).
  • Battery Monitoring Devices – Things like ESC (electronic speed control), LVC (low voltage cutoff), Battery Model numbers lingo.
  • Gearbox – Do I need one, how will it effect my battery life. Will it cause my battery to overheat?

There is lots more to consider when it comes to electric airplane motors, but in the long run it will be worth it to at least convert one of your current models to electric from the old rc gas burning engine.

One Final Thought: Electric radio control airplanes are not completely free from fuel dependency, after all we need to charge those batteries, and to do this, where does the power come from? it comes from coal burning power plants (a few nuclear, hydro-electric, solar, wind and natural gas power plants too). So the question is, what is the lesser of two evils? Well, when you consider the refinery that has to also power to create the nitro methane fuel for your gas rc engines, it does seem a better choice to select an electric engine.

If you are really concerned about the environmental impact, there are some ways to offset the production of your energy and gas usage. You can purchase carbon credits, or even ask your local power company to offset your power consumption with wind power. Both of these alternatives are a good way to balance your use of power and gas for your electric radio controlled aircraft and nitro-methane gas use.

If you have any comments or need more help, I would be glad to answer any question you have.
