Beyond an abundance of features at an affordable price, the XP9303 further distinguishes itself with innovative programming, fully-assignable switches and a Rolling Selector System interface that's hands down the most intuitive in its class.

A true breakthrough in versatility, the 9 channel, 30 model memory, 3 model type XP9303 will adapt to your RC needs at a level that’s absolutely unprecedented. Fact is, while the 9303 is right at home guiding the simplest of sport models, park flyers and gliders, its capacity for more complex assignments – including meeting the demands of a wide variety of competition disciplines – is virtually unlimited. So if you’re still working your way up to the challenges and thrills of large aerobatic models, multi-engine scale planes, 4 wing-servo camber-changing sailplanes, the latest CCPM helicopters or sport-level jets, the XP9303 will be ready when you are.

Detailed Information

Even before you explore the XP9303’s virtually limitless programming options, you’ll be sure to notice its incomparable feel – its ultra-smooth sticks, precision switches and levers, innovative Rolling Selector, plus case ergonomics that’ll have it melting in your hands. It’s the unmistakable feel of JR quality, and you’ll experience it every time you remove your 9303 for yet another of the countless flying sessions you’re certain to enjoy with it.

Whether your favorite planes are engine or electric, scale or aerobatic, basic or complex, the XP9303’s airplane software has everything it takes to bring out their best - and everything it takes to make flying them the most enjoyable experience possible. For instance:

- There’s a 3 position flap program whose elevator compensation provision includes a delay feature to smooth its position-to-position transitions.

- Using the 9303 “Wing Type” screen’s channel assignment feature, setting up synchronized dual–servo elevators, rudders, ailerons, flaps – even throttles – is a walk in the park.

- Taking advantage of the radio’s Triple Flight Modes (which are selected by a single, 3-position switch), offers in-flight re-configurations that can really reduce pilot workload. (Imagine what 3 different sets of rates, trims, mixes, etc., can accomplish when they’re activated by the flick of only one switch.) A bit more time to set up? Sure. But pros will agree: It’s time well spent.

- By using creative combinations of the 9303’s multi-function button switch (ordinarily just a “snap roll button”), its multi-point mixes and independently adjustable servo speed feature, inventive modelers will achieve a myriad of unique functions for special control and accessory operations.

- Flyers using the 9303’s gyro system will discover it’s the most versatile ever. It handles multiple gyros, then makes it possible to switch activate them or even tie them into flight modes.

- With the 9303’s throttle curve feature, it’s possible to customize your throttle response just the way you like it. Torque-rolling aerobatic flyers can, for example, flatten throttle response in the hovering range. Scale flyers will create a more linear throttle response. And twin flyers will find this invaluable for synchronizing engines.

  1. Multi-function button switch. Besides working as a timer or snap roll button, it’s assignable to numerous 2-position tasks. Retracts are an example: Touch once for gear up, touch again for gear down.
  2. Dual rate switches may be used as designated. Triple rates are available as components of the 9303’s flight modes, when they’re activated.
  3. Dual side levers offer handy access and flexibility when they're used with a program mix and/or assigned to virtually any function you choose.
  4. The XP9303’s flexible and versatile programming requires phenomenal memory and processing power. Not surprisingly, the 9303 employs an advanced, powerful microprocessor with nearly 6 times the RAM and ROM of previous generation systems.
  5. Largest-in-its-class dot matrix display enhances comprehension and accommodates more information at a higher resolution.
  6. JR’s innovative, exclusive Rolling Selector System is at the heart of the 9303’s programming operation. You’ll roll to scroll, press to select, roll to adjust and press to store. It’s fast and it’s intuitive.
  7. JR’s exclusive 3+1 trim system combines the precision of 3, digital flight-axis trims with an analog throttle trim for immediate visual and tactile reference to idle position.

Function Menu: All airplane programs are easily accessed through a single screen. Using the Rolling Selector, move the cursor over the desired program, and press. Also, as you add functions, the list changes. For example, if the flap system isn’t activated, it won’t appear in the menu.

Have it your way! Using a programmable mix, you can assign 18 different switch/stick/lever/buttons to activate programmable mixes. This allows the user to have a button, or a lever, a stick, or a switch activate a function. 6 programmable mixes are available.

Channel Naming: Screen layouts are simple and easy to understand. In this example, the program has automatically renamed the aileron, elevator and rudder channels when the dual servo system has been activated.

Triple Timer System: Not only does the 9303 offer an integrated timer (to keep track of time on the model), but both stopwatch and “down” timers are offered to time individual flight time. This can save your model by preventing fuel exhaustion. Timer activated by button.

Dual /Triple Rates : As shown here, the 9303 actually features triple rates when flight modes are activated. One, three-position switch gives you independent rates on aileron, elevator and rudder to reduce pilot workload.

Two Multi-Point Mixes: In some conditions, the proper mix may be non-linear. For these situations, the 9303 offers two multi-point mixes with 7 fixed points that are fully adjustable in .5% increments. Very helpful for rudder-to-elevator, flap-to-elevator and numerous special functions.

Throttle Curve : Want to correct a non-linear throttle response? Or make the throttle of your 3-D plane less sensitive while hovering? How about matching your left engine to your right? You can accomplish it all with the 9303’s throttle curve system.

Pre-Mixes for Aileron-to-Rudder; Elevator-to-Flap : These common mixes are provided by “pre-mixes”. You can choose 1 or 2 pre-mixes, then assign them to a variety of switches -- or flight modes -- as needed.

Bi-Directional, Adjustable Servo Speed: Scale flyers rejoice! Not only can you adjust servo speeds to up to 15 seconds for full transit, with your 9303 you can adjust different speeds for different directions. It’s very handy for electrically operated gear doors, scale functions, actuators, etc.

Three Position Flap System with Delay: This new flap system provides easier actuation of all aspects of a three-position system. Each flap position – plus any required elevator compensation - is specified using the Rolling Selector. Additionally, when flight modes are activated, flap positions can be assigned to any of the three flight modes. There’s a delay system (up to 2 seconds) for elevator compensation to ensure smooth transitions.


It has come to our attention that early 9303 transmitters have issues when using Model Transfer or Trainer features between mode two and mode one transmitters. If your 9303 is an early unit and you anticipate using the Trainer Function or Model Transfer with different mode systems, please send the transmitter to Horizon for a free update.
