The Decathlon is widely known to be one of the best aerobatic trainers in full-scale aviation! Its iconic design traces its roots back to the Aeronca Champ and Citabria but was upgraded with inverted fuel and oil systems plus a nearly symmetrical wing to allow it to perform “outside” and inverted maneuvers with ease. The E-flite® Decathlon RJG 1.2m is a conveniently sized replica of the Decathlon that RJ Gritter (RJG) flies. RJ is a nearly lifelong RC pilot who started competing in aerobatics at age 16 in both national and international events. His passion for RC aerobatic flying also led to a strong interest in full-scale aerobatic flying. RJ designed a new scheme for his Decathlon for the 2024 airshow season and was also involved in the development of this one-of-a-kind model that’s capable of smooth sport flying along with more aggressive aerobatic flying too! It features LED landing and navigation lights plus a variety of scale details to deliver an authentic flying experience perfect for low-time and intermediate pilots interested in honing their aerobatic skills, and experienced pilots focused on performing the most aggressive aerobatics. It’s equipped with digital, metal-geared servos all around, plus a 3S and 4S compatible power system featuring a 45A Spektrum Avian Smart Lite ESC. The BNF Basic version is also equipped with an AR631 receiver to deliver real-time telemetry data along with AS3X and SAFE Select technologies.

About RJ Gritter

“The son of a test pilot dad and a flight instructor mom, RJ has been in the cockpit his entire life. Growing up around the airport in Greensboro, North Carolina, he started flying before he was tall enough to see over the instrument panel! He soloed on his 16th birthday and got his private pilot license on his 17th.

RJ developed a passion for aerobatics through radio-control (RC) flying. He started competing in RC aerobatics at age 16 in national and international events, representing the US in indoor precision and freestyle aerobatic championships. RC flying gave him a strong background for “full-scale” aerobatic flying.

RJ earned his bachelor’s degree in Aerospace Engineering from North Carolina State University. After graduation, he moved to northern Virginia, just down the street from the Bealeton Flying Circus! He got his Decathlon at the end of 2015 and has since flown over 800 hours in the airplane, flying his first airshow in 2016. Since then, he’s flown hundreds of performances and has loved every minute of it!”

Video Overview
Skill Level 2 – Some Experience Required

Skill Level 2 – Next Step After a Trainer aircraft, like this one, are suitable for RC pilots who have successfully learned to fly a trainer model and those with the skills to assemble, set up, and fly similar class models. Although this is one of the best-handling and easiest-to-fly Decathlon models, it’s not a suitable first-ever RC aircraft for new pilots. You should have the experience and skills necessary to successfully fly a trainer model like the HobbyZone AeroScout 1.1m and Carbon Cub 1.3m, or models like the E-flite T-28 Trojan 1.1m, Valiant 1.3m, Turbo Timber Evolution 1.5m and other similar class models before attempting to fly the Decathlon RJG 1.2m.

Are you new to flying RC (Radio Controlled) aircraft? If you are, the Decathlon is not a suitable first-ever RC model, and we recommend learning to fly with one of our purpose-built trainer aircraft, such as the HobbyZone® Carbon Cub S 2 1.3m ( It’s equipped with exclusive and innovative SAFE technology that makes it possible for almost anyone to learn to fly successfully! The Ready-To-Fly (RTF) Basic version includes nearly everything needed to fly (except for a compatible LiPo battery and charger that are sold separately, or together in a money-saving Powerstage bundle) and is a perfect choice if you’re a new RC pilot. You can even use the DXS transmitter and the 3S 2200mAh battery used for the Carbon Cub to fly the Decathlon RJG 1.2m BNF Basic version after you learn to fly RC!

Exclusive Technologies

This BNF Basic version is equipped with exclusive Spektrum AS3X and SAFE Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you’re flying a much larger airplane. Optional-use SAFE Select offers pitch and bank angle limits plus automatic self-leveling that can be turned on and off at the flip of a switch! If you don’t want to enable the SAFE Select features, bind the receiver normally and only AS3X will be active.

Spektrum Smart Technology

The Decathlon RJG 1.2m is equipped with an exclusive Spektrum Avian Smart Lite ESC that can provide a variety of real-time power system-related telemetry data, including motor RPM, current, battery voltage, and more – with Smart and non-Smart batteries – via compatible receivers (including the AR631) and Spektrum AirWare™ equipped transmitters (including the DX6e and 8e, DX6 G2/3 and 8 G2, the DX9, NX6 to 20, iX12 to 20, and others) while you fly. It also features optional-use motor/thrust reversing that offers special ground handling and other capabilities!

Versatile Power

The factory-installed brushless power system features a 45-amp Spektrum Avian Smart Lite ESC plus a specially tuned motor that delivers an abundance of thrust with a 3S 2200mAh LiPo battery, or more speed and unlimited vertical performance with up to a 4S 3200mAh battery – without the need for any modifications or upgrades!

Scale Features

Functional LED landing and navigation lights, wing struts, and wheel pants are scale features that take your experience to another level.

RJG Trim Scheme

Factory-finished in the classic yet modernized red, white, and blue trim scheme featured on the full-scale Decathlon RJ Gritter (RJG) – a lifelong full-scale and RC pilot – flies in airshows across the United States.

Easy Assembly

No glue is required for final assembly, and you can have the Decathlon RJG 1.2m ready to fly in less time than it takes to charge a battery! And although it’s conveniently sized to fit fully assembled in almost any vehicle, you can remove the one-piece wing for easier storage and transport. Thumbscrews, hands-free connections, and quick-release struts mean you can remove/install the wing in just a few minutes without using any tools.

Bind-N-Fly Completion Level Advantage

Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!

This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX® receiver featuring AS3X (Artificial Stabilization–3-aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence. The result is a heightened sense of stability and precision that makes you feel like you’re flying a much larger, expertly tuned aircraft.

If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE® Select flight envelope protection technology built into the receiver. No programming is required. Simply change up the binding sequence as directed in the manual.

With SAFE Select enabled, you get:

Pitch and Bank Angle Limits

  • These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.

Automatic Self-Leveling

  • The airplane instantly returns to and holds level flight when the sticks are released and in the center position. It’s also helpful for keeping the wings level during takeoffs/launches and landings.

Easy Switch Assignment—No Complex Programming Required

  • The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn’t require any complex programming and takes just a few seconds.

If you don’t want to enable the SAFE Select features, just bind the receiver normally and it will function like a standard AS3X receiver.
