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.
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.
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.
Dual rate switches may be used as designated. Triple rates are available as components of the 9303’s flight modes, when they’re activated.
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.
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.
Largest-in-its-class dot matrix display enhances comprehension and accommodates more information at a higher resolution.
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.
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.
DSM or Digital Spectrum Modulation is Spektrum's proprietary method of implementing 2.4GHz spread spectrum technology for the R/C industry. DSM divides the 2.4GHz band into 80 individual channels (frequencies) and incorporates direct sequence spread spectrum with an embedded GUID (Globally Unique Identifier) code. DSM has been painstakingly optimized by our engineers for RC surface and aircraft use, offering the most robust RF link in the industry.
DSM2 is the 2nd generation of Spektrum DSM technology and remains a premier 2.4GHz choice even today. Using the same superior wideband DSSS foundation that all Spektrum technology is based on, DSM2 consistently provides faster response and more precision than most non-DSM 2.4GHz protocols.
DSMX is a natural evolution of DSM2 technology that is the result of several years of development, optimized for pilots and combining Wideband DSSS and Frequency Agility. It builds on what has come before and takes DSM to the next level of robustness, reliability and efficiency without leaving current DSM2 users behind. DSMX represents the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.
The foundation DSMX is built on is the same foundation as DSM2™ - the superior on-channel interference resistance and coding gain of wideband DSSS. Compared to the wideband signal of a DSM2 or DSMX™ system, the narrow-band signal of other 2.4 transmitters is more likely to suffer crucial data loss in the event of on-channel interference. Think of wideband 2.4 as a river and narrow-band 2.4 as a stream. It takes much more interference to stop a river than it does to stop a stream.
The big reason wideband is so robust is coding gain. Essentially what this means is that the unique coding in a DSM2 or DSMX wideband signal allows it to be heard well above the noise of surrounding 2.4GHz signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrow-band competition using the same amount of power.
For the most part, yes. DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both. The only exception is the DXe which is DSMX-only and not compatible with DSM2 receivers.
Yes, but DSM2 users who rarely, if ever, fly in big events or other "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need. The difference DSMX makes is only apparent when hundreds of 2.4GHz systems are in use at once. To see if your transmitter is eligible for the DSMX add-on, please visit horizonhobby.com, click on the “radios” tab, and select “DSMX addons” for more details.
A resequencing of the data a Spektrum transmitter transmits based on the type of mixing you select. This feature helps to sync control services that are connected (such as a swash plate on a helicopter) and is used in radios that have many channels.
The Spektrum™ X-Plus™ 8 module lets you add 8 fully proportional channels to specially equipped Spektrum transmitters and receivers with 10 or more proportional channels. Just plug it into the X-Plus port of a compatible receiver. It is ideal for scale modelers who like to push realism to the extreme with working accessories and lights in addition to the regular control functions. The DX10t and DX18 offer X-Plus.
You should have no problem maintaining control as long as you maintain direct line-of-sight with your model. If you try to fly behind a group of trees or otherwise obstruct your direct line-of-sight, you could be susceptible to losing your control link.

The only difference between the air and glider systems is the switch labels. The difference between the air/glider system and heli systems is the switch positions and their corresponding labels. One of the 3 position switches is moved from the left front on the air system to the top left on the heli which is the FM switch for the heli . The gear switch on the air is on the top left back position, and moves to the front left position on the heli where the 3 position switch is on the air . The air has a trainer/snap roll button on the top left side, which this changes to a long momentary switch that is moved to the top left back on the heli . Programming wise however, they are identical for all 3 types.
Early 9303 systems had a problem with 140 CCPM mixing, causing uneven servo travel. JR has made the programming changes necessary to correct this problem. The service center has the equipment necessary to correct this issue. To find if your system is affected, go to a clear model, activate 140 CCPM, then go to the servo monitor. If you give elevator (fore or aft cyclic) and channels 2 and 6 which are the 2 rear servos do not travel the same amount which would produce a left or right roll (left or right cyclic) your system is affected. If they travel the same amount, your system is unaffected.
When the transmitter is in close proximity to the receiver the modulated signal can be overdriven. This condition is referred to as "swamping." By collapsing the antenna and stepping away from the model, you should see this condition dissipate.
Make sure to perform a proper range check and then extend the antenna before operating the model.
PCM. It has advantages over FM: less susceptible to noise, fail-safe programming, and better servo-positioning accuracy. However, FM is generally more affordable. The difference in range between PCM and FM negligible.
Any JR module will work in any JR transmitter that accepts a module.
