How to be sucessful with your maiden voyage

After you have purchased your brand new rc airplane and have followed the directions, such as charging the batteries and "trimming" the elevator and rudder you're ready to FLY! Now you need to find a large field (about the size of a football field) with a well-manicured baseball diamond or a connected parking lot. Check the hourly weather forecast on accuweather.com. Do NOT fly in winds over 3 mph on your first flights. If the flag on the flagpole at the school is moving it is TOO windy.

There are four steps that every pilot most complete to have a successful flight: (1) pre-flight check (2) take-off or hand launch (3) fly at a safe altitude and (4) landing. By far the most challenging step is landing and then taking-off. In this post I will break down each step and tell you what you must do to make your maiden voyage and every flight afterwards a success (but please note: we all crash, no matter if we have been flying for 2 minutes or twenty years. This is a fact and a reality of the hobby).

Pre-Flight Check (in this order):
- Turn transmitter on (put throttle at neutral)
- Turn on plane or plug in battery
- Check the "trim" for the elevator and rudder
- Test controls
- Walk 35 feet from your plane and continue to test controls (watch for glitches)
- Take two minutes to visualize your flight plan from take-off to landing

Take-Off:
- Determine the direction of the wind (Note: you MUST take-off and land into the wind)
- Give yourself a runway of 40 plus feet (width of a baseball field)
- Turn on your timer/alarm so that you know when your battery is low and you must land
- Give full UP elevator (hold that position)
- Give 50% throttle to allow tires to grip ground and get plane going straight and solid
- Give 100% power
- Once plane lifts from ground RELEASE up elevator
- Climb slowly and fly in a straight (if you must turn make it VERY wide)

The Flight:
- Reach an altitude of no less than 60 feet (you want to be 3 mistakes high. 1 mistake is 25 feet)
- Fly in a big square making right turns and follow this for a while, then switch up and make left turns
- Set your trim so your plane flies straight and level at 70% power
- Note: any time you turn sharper than 90 degrees you will loose altitude
- Use the throttle speed to climb, drop, or maintain altitude
The best advice I can give you is "let the plane fly itself. Steer it ONLY when you have to."

The Landing (read the "how to land" article of masportaviator.com):
This will sound crazy . . .
- fly your plane to the ground
- up elevator will SLOW your plane down
- the throttle/speed will make your nose dive or level out, you will need to give speed to your plane to get the nose to lift a little, BUT beware this will NOT make your plane go faster
Here's how to do it:
- Continue to fly your flight plan, but on each pass (straight away) cut power by 15-20%
- When you are 15 feet from the ground make a big turn towards the wind
- Slow the throttle down more, but not so much as to drop the nose
- Fly in a long straight line to the ground
- When you are 3 feet above the ground, cut power and give up elevator
- The plane will land itself
- Now turn off receiver first and then the transmitter

Note: for your safety and wallet make sure to always (1) turn transmitter ON first and then receiver/ airplane and (2) to turn OFF receiver first and then transmitter. While bench testing my newest plane, before its maiden flight, I forgot to act on this rule and within seconds smoke rised from my plane. I burned out my speed control. The prop was locked against my leg. If the prop had not been locked, I would have been cut up to boot!

Remember to be modest with the controls. Over sticking will definitely cause you to crash.

Which rc airplane should I buy?

Choosing your first remote control airplane can be a daunting task. Experience has taught me that this choice is based on two questions, which each aspiring pilot must answer for him/herself. Those questions are (1) how much money am I willing to spend and (2) is this a short or long-term investment for me? The answers to these two questions will help you focus your research, resulting in the best first airplane. This post will offer you a few affordable entry-level park flyers with brushed motors, which can be flown at your local high school football field.

The most basic airplane can be purchased for under $50 and will include all you need to get your bird in the air. The most trusted brand that I have flown is Hobbyzone. I have seen these planes crash into fences, trees, and walls and be back in the air within minutes. I can't speak highly enough about these planes. My friend Dave, a fellow pilot, learned to fly using his Hobbyzone Firebird Outlaw (see video below).





The Firebird Outlaw, which Dave flew has been discontinued and replaced by the Firebird Scout, pictured left. You can find a review and video of the Scout on masportaviator.com.





There are two negatives to these types of airplanes: (1) you can not reuse the electrical components inside if you destroy the plane and (2) they are 2-channel airplanes, which means 1-channel is dedicated to the "throttle" for the motor speed (which correlates with altitude) and the other channel is dedicated to "turning." What this means is the plane does not have an elevator and the only way to bring it back down to the ground is by slowing the motor speed -- if you are down wind on a windy day you will not be able to fly back to yourself.

$50 RTF (Ready-To-Fly) planes are perfect for those with a smaller budget, who are not sure if the hobby is for them. These planes also make great first planes for youngsters.


The next level of investment is $89. This is the plane that I recommend most for under $100. The plane is called the Wing Dragon and is sold by hobby-lobby.com. At times, it goes on sale for $79. This package is very complete. It includes both a wall and car charger for the battery. And most importantly it includes a flight simulator, which allows you to plug the radio into your PC and fly the Wing Dragon and many models on your computer before taking it to the sky. Thirty minutes spent on a flight simulator, prior to your maiden
voyage will help you immensely -- it increases your chances of a successful flight. I have personally flown this plane & the flight simulator and I am very impressed with both of them. The Wing Dragon is a 3-channel plane, which offers you full control of the aircraft. Furthermore, it is extremely durable. I have seen this plane fly 15 mph head-on into a parking lot curb and not incur any permanent damage. It has great flight characteristics. Hobbyzone also offers 3-channel planes, but they cost $140 on up; therefore for the money the Wing Dragon cannot be beat. You can find videos and a few reviews of the Wing Dragon at hobby-lobby.com.

For $160 you can purchase a 3-channel Hobbyzone Super Cub, which is a beautiful airplane and a perfect first plane. It offers you full control with throttle, rudder, and elevator. All Hobbyzone planes come with an anti-crash technology installed to better help beginner pilots fly and there is a switch for "advanced" pilot controls. Reviews of this airplane are positive.



But, before you commit to the Cub, you should also be aware that there is 4-channel Wing Dragon available for $140 and often less when on sale. 4-channels gives you throttle, rudder, elevator, and aileron – simply put a whole lot more control over the aircraft. The Wing Dragon 4 is capable of aerobatic flight, including inverted flight. This plane can serve as both your first and second plane, because it is 4-channel and the wings will dip when you turn and you will need to adjust the altitude accordingly. But, beware that will be more difficult to learn on than a 3-channel plane. In the long run you will save yourself $150 or more because you will NOT be buying a second plane with an additional channel -- ailerons. The Wing Dragon 4 includes the flight simulator and chargers too. Videos and photos are available at hobby-lobby.com.

The last level is for serious enthusiasts, who are committed for the long haul. My first plane and equipment cost about $450. I researched the planes I would like to grow into and identified what radio receiver and servos were required. I decided that I would buy a 5-channel computerized radio from the start so I would not need to upgrade my radio when I upgraded to a second or third airplane. I also bought a charger that would be able to charge many different types of batteries so I didn’t need to keep purchasing additional chargers every time I bought a new plane. I have three planes now and my radio works for all of them. I invested money upfront so I could save money in the long run.

There are so many planes to choose from at this level. I recommend that you purchase an airplane (1) made of extremely tough EPP foam, which is very easy to repair (2) with a wingspan of at least 35 inches, (3) has 3-channels: rudder, elevator, and throttle, and finally (4) has a dihedral top-mounted wing, which will provide the most stability and be forgiving in flight. Avoid ailerons to start. Avoid balsa wood planes or gas powered as well. A great plane to consider is the “Wingo USA” sold by hobby-lobby.com. You can even purchase floats for this plane and take off from and land on water.

I have spoken with many experienced pilots who regret starting off with a beautiful nitro plane as their first planes. Those planes make great third or forth upgrades. Also, please remember in this hobby you get what you pay for. Make sure to research and purchase the best plane your money can buy. If you can not find a review or a forum on the desired model at rcuninverse.com, rcworld.com, or E-Zone Mag -- don't buy it. A fellow pilot made the mistake of not purchasing a trusted brand for $80 for a 3-channel and has invested an additional $35-40 and hours of his time. In his case, purchasing a model for $80 like the Wing Dragon would have saved him a good amount of money and heart ache. For your first plane don't worry about the looks or being a "scaled model"; rather focus on stable flight characteristics and durability. You want a reliable plane to learn on.

Bottom line -- if you plan to fly your rc airplane for the next two years, the Wing Dragon USA would be your best choice for multiple reasons: (1) easy to learn to fly on (2) super tough and easy to repair (4) spare parts available (4) versatile . . . land/water (5) will remain challenging for a couple years to fly and (6) when you upgrade your plane you can reuse the components. Check out the review and videos on rcgroups.com. There is a great video of water take-offs and landings.

Powerful resources for you is your local RC airplane club and hobby store -- as well as rcuniverse.com, ezone mag, and masportaviator. Consider joining your local club! They will be able to train you to fly, just like driver’s ed, plugged into your radio. Many clubs have a club plane they use to teach people just like you.

Where I started from

Three years ago, after a 17-year hiatus from the hobby, I returned to the hobby of flying remote control airplanes. Since then I have acquired near 1,000 hours in obsessive and passionate research on electric powered remote control airplanes. When I first returned to the hobby I did not want (1) to nose dive and destroy an expensive gas motor, (2) limit where and when I could fly, and (3) I did not want to join a club and be a member of the AMA; therefore I opted to buy a electric foamie plane with a brushed motor. Since then I have learned and would do a few things differently. The goal of this site is to share what I have learned along the way so that you can make more educated decisions in your RC experiences.
