Advice for Getting Into Flying Radio Controlled (RC) Airplanes
By Ken Myers


     Please be aware that this is an opinion piece. MY OPINIONS are based on over 50 years of flying RC planes and well over 40 years as a RC flight instructor.

Where to Start

     YouTube has a lot of videos covering the topic of RC airplanes. That's good, but...

     Visiting an RC flying site, where you can actually see RC model airplanes in use, is better. Real life experience is invaluable. While visiting, you will see the area required to fly different types of planes and actually see various types of planes in action, as well as the support equipment being used.

     Local hobby shops, that have a good selection of RC equipment, usually have a list of known flying sites in the area

     The Academy of Model Aeronautics has a list of chartered flying sites.

     A search within 25 miles of my zip code showed 17 clubs in this area of southeastern Michigan.

     You may, or may not, want to join a club. That's fine. You should still try to visit a club in your area just to see the 'hobby' in action. There are links to the various clubs' Web sites on the AMA search site. Their Web sites usually have maps to their flying sites.

     Plan your trip on a good flying day. Do not try to visit an RC flying field when its too cold to be comfortable outside or when the wind is standing flags straight out and the traffic signals are swaying a lot.

     That tip about the 'weather' also holds true when you are learning to fly. While the day may seem very pleasant, temperature-wise, it may not be a good RC 'learning to fly day'. When just learning to fly RC planes, breezes should be at a minimum. It is imperative to be patient and wait for the correct conditions, whether you are teaching yourself or you have located a flight 'instructor/mentor'.

     YouTube videos show planes flying, but until you actually visit an area where RC planes are being flown, you have no reference as to how much area your choice of an RC training plane actually needs.

     Words like 'backyard' and 'park' abound in many sources. In reality, those descriptions, are at best, subjective, as to the actual physical size of the area. More importantly, the area to fly in is dependent on the skill of the pilot. As a beginner, your skill level is zero.

     Flying in a 'park', with others present that are not involved in your activity, presents a clear and present danger to them and it is a liability that you have chosen to introduce in that area.

     The area required is also dependent on the type of plane you select as your trainer. There are a lot of planes that make excellent trainers that cannot be flown in a 'backyard' or 'park'. You need more room than you think.

     The area needs to be clear of 'objects' such as trees, poles, fences, goals, backstops etc. If they are present in the area you've chosen to fly in, you WILL hit one of those objects.

     The YouTube video shows a beginner who chose to fly in a 'park'. It didn't work out well for him. He also made the mistake of not choosing a good trainer plane as his first RC airplane. Don't let this happen to you.

     Even very experienced RC pilots can misjudge and not choose the correct flying area.

     I wanted to do a maiden on a new 'park flyer' type plane, but I didn't want to drive out to the RC flying field I use. I did everything wrong. The area, a local park just down the street, was large enough. It was early enough in the spring that there was no one using it. Unfortunately, it is filled with many objects.

     It flew okay.

     The wind was quartering from my front right side, so I chose to land at an angle to how I was flying so that I could land into the wind. There were no leaves on the trees yet. I didn't see the 15 foot tall tree behind me and to my right. I flew right into its branches. The plane caught and rested in the branches about eight feet off the ground. A trip home, to get a ladder, was required to retrieve the plane.

     The point; choose an area that is larger than you 'think' you need and be sure it is free of objects. Choose to orient your flight so that takeoffs and landings are into the wind.

     This is a 'sad' video. The user was a low time pilot who chose a horrible flying site. If there are poles or trees, you WILL hit them. The pilot lacked both the skill to fly the plane, even though the advertising states in the supplier's video, "THE ALL-PURPOSE AIRPLANE THAT ANYONE CAN FLY", he also lacked sound flying site selection judgement. Don't let this happen to you!

     When setting up to fly, be sure that the sun is behind you while you are flying in front of yourself. If the sun is not behind you, you WILL fly the plane between you and the sun. It WILL happen. When it does, you WILL be blinded for several seconds. Spotting the plane again and picking up its orientation will be extremely difficult.

     About 5 seconds of this video shows what happens when a plane flies through the sun. The camera recovers much faster than your vision!

     Your flying gear should also include a hat with a brim and sun glasses. The brim, if worn to the front of the hat, will help shade your eyes for a better view of the plane and sun glasses will reduce squinting when looking at a bright sky. A bright sky can even happen on a totally cloudy day.

     Dark, totally cloudy, days are not good days for beginners to fly. No matter what color the training plane is, it tends to 'look' gray against a very gray sky. There is little definition between the plane and its background. Orientation becomes extremely difficult. Even very experienced pilots can 'lose' the plane for an instant with this type of cloud condition, but their experience usually 'saves' them, while a low time pilot can totally 'lose' orientation and crash.

     The Flite Test video shows two planes flying on a bright, yet totally cloudy day.

Getting Into It

     Selecting a good trainer airplane is extremely difficult. You will hear many, many, many opinions on what makes a good trainer. Your individual financial circumstances, personality and location play an important role in determining what plane will be best for YOU to begin with.

     No matter what decision, or path, you decide to follow, there are some basic 'rules' for selecting a plane that will work as a good RC trainer.

     Some, or all, of these suggestions should be taken into consideration when selecting your first aircraft.

1. The fewer the number of functions you control, the easier it is to learn.
     Controlling throttle, rudder, and elevator are enough to start with. The type of airplane that uses these three functions also uses a good amount of dihedral in the wings, and is therefore somewhat inherently stable. In other words the plane will fly by itself, without any inputs from you.
A. In RC, functions are known as 'channels'. Controlling the three functions of throttle, rudder and elevator is known as flying a 3-channel airplane.
B. Dihedral is the angle between wing panels. A high or shoulder wing position plane has the center of mass of the airframe beneath the wing. The center of mass below the wing and a decent amount of dihedral, as well as other design considerations, makes the plane inherently stable.

2. The plane should be 'relatively' slow. This allows your 'untrained' brain to 'learn' the stick inputs required to 'make' the plane do what you want it to do. A plane can only fly slowly if it has a low wing loading.

3. The plane should be somewhat durable. That doesn't mean that it won't break if an unintentional landing occurs, but that most of it will be flyable again soon after a minor repair. Foam type planes are, for the most part, the easiest to repair and get flying again.

4. The plane should not necessarily be 'beautiful' in your mind. Beautiful planes come later in the learning curve. There should be no fear of messing up your trainer in the back of your mind. If there is, you've chosen the wrong trainer.

5. Electrically powered trainers have almost no learning curve regarding the operation of the power system at the flying field. Turn it on and go flying. Gasoline and glow fuel powered engines do have quite a learning curve themselves. Move onto them later if you are interested in them.

6. The plane's flight characteristics must match the area you intend to fly in. It is not so much a matter of size of the area, but how much room the plane needs to land when flown by a beginner.

7. A larger size plane, with a low wing loading, is better to learn on than a smaller size plane with the same wing loading. The flying area must be suitable for landing the larger size plane.

8. Your progress is totally based on you as an individual. Some folks pick up RC flying more quickly than others. How quickly it is 'learned' depends on often RC flying can be practiced and how frequently the sessions can be connected.

Acquiring Your Trainer

The Types

Ready to Fly (RTF), everything is in one box that allows you to make one flight and then wait a considerable time for the provided single battery to recharge on the extremely low powered battery charger provided in the box.

Bind and Fly (BNF), almost everything is in one box that allows you to make one flight and then wait a considerable time for the provided single battery to recharge. A Spektrum brand transmitter (Tx) is a required purchase to match the Spectrum receiver (Rx) installed in the plane. Tx-R (transmitter ready) planes, sold by Tower Hobbies require a transmitter that can transmit on the SLT protocol; Tactic or the newer Hitec. FTR (Futaba Transmitter Ready) planes, sold by Motion RC, require a Futaba transmitter.

Receiver Ready (Rx-R) or (RR+), much of everything is in one box that allows you to make one flight and then wait a considerable time for the provided single battery to recharge. A transmitter (Tx) and receiver (Rx) of the user's choice is required.

Ready Built/Plug and Play (PNP) or (RR), much of everything for the airframe is in one box with some onboard equipment installation completed. Some assembly of the airframe is still required by the user. It also requires the battery, battery charger, transmitter and receiver to be purchased separately.

Almost Ready to Fly (ARF), contains the pre-finished airframe parts ready for assembly. The user must install the radio system and power system of choice.

Kits, assembly from some type of construction material is required. All of the components for the power and radio system must be selected by the builder and installed.

Scratch Built, the airplane is built from plans using some type of construction materials. All of the components for the power and radio system must be selected by the builder and installed.

Glow powered trainer conversion to electric power, ABSOLUTELY NOT FOR BEGINNERS.

Self-designed, scratch built, ABSOLUTELY NOT FOR BEGINNERS.

Preferred Design and Function Types for Trainers

1. 3-channel electrically powered gliders
     They are slow flying due to their light wing loadings. They are the 'easiest' to learn to fly. Using only 3-channels/functions, keeps them light. Do not select 4 or more channels and anything noted as FPV (first person view) gliders as your trainer glider. Those options just make them 'heavy'. They come later in the learning curve.

2. 3-channel electrically powered glider-type pushers
     This used to be a very popular group of trainer planes with about 50" wing spans. The most notable was the Multiplex/Hitec Easy Star. They were gentle and slow fliers because they are directly related to gliders. It appears that only much smaller, 30ish inch, versions are available today. The larger ones have been changed into 4-channel/function types, and many are being recommended for first person view (FPV). They are not good trainers when they become over-loaded with unnecessary functions.

3. Micro 3-channel Trainers
     There are small, usually under 36", type planes. They will work as trainers in smaller areas, but are susceptible to wind.

4. Conventional (tractor type) 3-channel Trainers
     These are larger than the the micros, handle wind better, but require a larger, clear flying area.

5. (Pusher type) 4-channel/function glider-like
     Again, these are larger than the the micros, handle wind better, but require a larger, clear flying area.

6. Conventional (tractor type) 4-channel/function Trainers
     These planes will work as trainers, especially with an instructor. They require a relatively large flying and landing area, but they tend to handle wind a bit better for beginners. They also require the highest initial investment.

Other REQUIRED Items That MUST BE PURCHASED Besides the Trainer Plane

     There are NO trainer planes that come with everything you actually need; zero, nada, zip!!!

     Many suppliers 'suggest', as optional items, more batteries, a 'better' battery charger and most importantly of all, a fire resistant container for Lithium Polymer (LiPo) batteries.

     Those three items are REQUIRED to learn how to fly RC planes and to protect yourself and your property.

     More than one battery is required, unless you want to wait an hour or more between flights. That is the typical time it takes a depleted LiPo battery to recharge, especially with the provided chargers in RTF and BNF packages.

     The chargers supplied in RTF and BNF packages are dumb. They provide no information to the user as to the state of charge or milliamp hours (mAh) returned to the battery during a charge.

     LiPo batteries should never be drained to more than 80% of their stated capacity. The mAh returned to the pack is used to determine how deeply the battery was discharged.

     The supplied chargers could also be called, "Plug and Pray" chargers.

     LiPo batteries should always be charged outside your vehicle, or your house, on a noncombustible surface and away from anything combustable.

     Some of the "Plug and Pray" chargers plug into an accessory socket of a vehicle with a chord that is not long enough to exit the vehicle, so that the LiPo battery cannot be charged outside the vehicle.

     Other supplied chargers plug into a USB port. That port could be on a device in your house or your vehicle.

     Some are even supplied with an AC adapter to charge in your house.

     Both types of supplied chargers are a bad idea just waiting for a LiPo event to happen.

     LiPo batteries can contain a lot of energy. They are energy dense when fully charged. They should NEVER be stored for long periods of time at the full charged state.

     Some folks say that stored LiPo batteries, not fully charged, have no risk of causing an event.

     I personally know two people who will disagree with that statement, as they both had 'stored' LiPo events.

     Here is a link to some more reported events on RC Groups.

     I can only recommend one brand of LiPo Sack or Bag, the real LipoSack brand from Mark Wood in California.

     There are cheap bags. They will actually burn.

     The video shows many other brands actually have a coating on them that will burn and add fuel to the incident.

     To learn more about LiPo incident containment, see Part 2 of "Learning About LiPo Batteries".

     Disclaimer: I do not know Mark Wood. I have never met Mark Wood. I have NO financial interest in LipoSack. I am a paying customer, like anyone else.

     Please, do yourself a favor and purchase only the REAL LipoSack that meets your needs. It is made here in the USA and it is really cheap insurance.

Another Item Needed - a Timer

     LiPo batteries should not be discharged to lower than 80% of their stated capacity. A flight must be timed to keep this from happening. A timer on a smart phone or inexpensive kitchen timer can be used. Some computer-style radios have built-in timers.

My Top Five Picks

     I extensively researched 30 RC planes which suggested, in their literature, that they were 'trainer' types. The complete list, and my notes are located here.

     I was very surprised, after analyzing my data, that four of the five planes I am recommending are from Horizon Hobby. All four have AS3X stabilization and two also have a version of SAFE.

     Watching about one minute of this Flite Test video gives some important information about using SAFE and weaning off it as soon as possible. Don't confuse SAFE and its variations with AS3X stabilization.

     I've tried to give a close approximation to the actual amount of money that might be involved in getting into the hobby. I have included an extra battery or batteries, a decent charger for the type of battery and a LiPo sack in the pricing to more closely reflect the actual cost. Shipping and taxes are not included.

     Specific recommendations, my comments regarding the aircraft and links for purchasing items can be found here.

Plans & Build Page

     Building from a kit or scratch building from Flite Test's free plans is an excellent way to enter the hobby.

     If you think that you can't build your own trainer, watch the build video to see how easy it can be with the help of the folks at Flite Test.

RC Flight Simulators

     Some people find computer RC flight simulators useful in learning hand to eye coordination and enhancing muscle memory.

     The Phoenix R/C Pro Simulator V5.5 with DX6i Transmitter is $219.99. The transmitter is a generation old, but could be used instead of the DXe mentioned in my component listings.

     The Great Planes RealFlight RF8 w/InterLink-X Controller is $179.99. The controller can only be used with the simulator.

     A Detrum 8-Channel R/C Flight Simulator Controller is $29.99. It requires the purchase of the ClearView RC Flight Simulator for $39.99.

     The Dynam 6CH 6-Channel FMS USB RC Flight Simulator DYU-1002 Mode 2 Left Throttle Packaged with the free FMS RC simulation software can still be found on Amazon for $29.64. Do a search on Amazon for it.

     More information on RC flight simulators can be found in the RC Groups Simulators forum.

     Almost all RC Flight Simulators computer programs are for Windows OS systems.

     I wrote a review of AeroFly RC7 for the Mac.

An Alternative to RC Flight Simulators for some might be an Indoor RC Venue.

     Many areas in the USA have venues that allow indoor flying for certain types of small RC model aircraft.

     A Google search for indoor RC flying in your area might list some of these venues with dates and times.

     Unfortunately, indoor RC flying is scheduled at venues when they are not being used for their primary purpose, and that means the hours for RC flying are generally while folks are at school or work.

The Power of Two
By Ken Myers

     It has been my life experience that when I have two of the same, or very similar things, the first one will last longer than when I have just one of a kind.

     The photo shows just a few of the 'twos' I have and use all of the time. So far, all of the 'ones' are working just fine, but who knows what would have happened if I only had one and really needed to use it right then!

     My new 'trainer' plane was designed with "The Power of Two" in mind. Based on my experience, the first airframe should lasts a long time (or not). If something does happen to it, so that can't be easily repaired, then the number "two" airframe can be set up quickly. This allows the student pilot to get back into the air in a timely manner.

     Another "plus" for two airframes is that many of the airframe parts from the original number one airframe, if it should become unrepairable, can be used to create another number "Two" airframe. That cuts down on the total building time for the new number "Two" airframe, as well as the expense.

Special Events again for this year for NCM (Not Conventional Materials) aircraft.

     Traditionally, model aircraft airframes have been mostly constructed from balsa wood, plywood, spruce, and fiberglass. For the purposes of this meet, NCM airframes are mostly constructed from not conventional materials i.e.; sheet foam, foam board, cardboard, block foam, foam insulation material, etc.

Foam Flurry for NCM aircraft: This is a true event. It is based upon the all up/last down event of early electric meets. Any NCM aircraft may be used (no ARF types). Power systems are limited to a maximum of 3S (no paralleling) LiPo batteries or 4S maximum, no paralleling, for A123 packs. All planes qualifying for this event will launch at the same time, and the last one to land will be declared the winner.

Most Unique NCM Aircraft Award: An award will be given on Sunday to an aircraft in the NCM category that is judged as 'most unique' by the Mid-Am panel of judges.
