I’m sure you’ve heard the old saying, “Lightning can’t strike twice in the same place.” Well, it’s time to rethink that statement, especially with the latest offering from JR: The Z-1. KO Propo and JR have reunited to combine the ergonomics and software from the EX-10 Helios, one of the most popular and user-friendly radios to have hit the scene in some time, and the synthesized module and receiver concepts from JR to create what some might call the perfect marriage. While the Helios and the Z-1 may look similar, there were several key changes and improvements made before the JR name would find its way onto the new JR Z-1.

Module and Receiver:
When the XS3 transmitter was released, one of if not the most unique features was its 100% crystal-less design. While there were other “conversion kits” that you could purchase to be completely crystal-free, this was the first radio setup to come straight from the factory that was synthesized. As time went on, the XS3 was upgraded to Pro status, at that time also introducing the smaller RS310 synthesized receiver. Well the RS310 has found itself a new home, and is included as standard equipment with the Z-1. But you can’t just have a synthesized receiver, so an all-new module was developed for the Z-1 to unlock the final piece in the crystal-less puzzle. In all, you will have thirty frequencies available at the turn of a dial. Talk about easy.

Easy Menu Access:
Many radios on the market have a ton of bells and whistles, but if you can’t get to them, don’t know how to change them, or don’t know what a feature does, all the extra gadgets are worthless. While the Z-1 has a ton of features and adjustability, getting to them and making changes is an absolute breeze. The

Z-1 features a handy jog-dial to maneuver through your menus. The large dial just to the right of the wheel makes moving through your menu options a snap, but if that’s not your style the + and – keys allow you to manipulate around the menus as well. Once you have the feature you wish to adjust highlighted, all you need to do is press the “Enter” key, and you are in the sub-menu you desire. Talk about intuitive.

Innovative Functions:

If this radio were all about the synthesized capabilities, we could just stop here. But as we all know, there’s a lot more under the sun. From basic options such as the 9-model memory and the gorgeous backlit display, to more advanced features such as ABS (anti-lock braking system), throttle and steering curves, punch, speed, and more, the Z-1 can truly help you get dialed in to almost any situation. And

speaking of dialed in, you can make speed controller and servo adjustments from your pit area with the optional DSC cable (JRPA134) without having to worry about whether someone else might be on your frequency. Talk about smart.

Awesome Add-Ons:
	Much like its KO cousin, the JR Z-1 can use many of the same upgrades and optional components. Drop-down wheels have become the rage among many racers, and the optional Multi-Angle Wheel Extension (KOP17004) is a direct bolt-on item for the Z-1. This option not only lowers the wheel height, but it also allows you to swing the wheel in or out to really fine-tune the comfort level for any specific user. Want to add some flair to your Z-1? You have that option too with the Red (KOP16121) or Blue (KOP16132) colored grip pads. And don’t forget about the optional
software and cables (KOP61001) that really unlock much of the Z-1’s versatility. With the data cables and included software it is possible for you to connect the Z-1 to your computer to back up settings, store additional profiles, and even customize different alerts and tones on your Z-1. Talk about personalization.

Unbeatable Support:

Some companies think a 30-day warranty is pretty good. Others will extend that out to 90 days. JR isn’t fooling around, that’s why the Z-1 is backed by a full 3-Year warranty. If you ever have a warranty issue with your Z-1, simply send it into the JR Service center with a copy of your receipt and you are covered. No other company in the industry offers this level of post-purchase support. Talk about common sense.

When it comes to the serious racer, nothing but the best will do. It was with that in mind that JR once again set their sights on being at the absolute pinnacle of performance. Whether you are talking about a radio that is easy to use, smartly designed, has an industry best 3-Year warranty, that you can personalize, or one of the most intuitive radios you can find, it seems like everyone will soon be talking about the new JR Z-1.

A: In testing and development, the RS310 has been able to work in the same HSR mode as the KO Helios. There should be no noticeable difference between the way the Helios and the Z-1 work in the HSR mode as long as you are using a servo that is HSR compatible.

--------------------------------------------------------------------------------

Q: Will there be a version of the Z-1 released that comes with a 27MHz module and receiver?

A: There aren’t any plans to release a 27MHz version of the Z-1 since its synthesized module and the RS310 offer 30 different frequencies—more than the vast majority of racers will ever need.

--------------------------------------------------------------------------------

Q: I have a Helios already; can I use the Z-1’s synthesized module and RS310 receiver?

A: Absolutely. The module port and pin configuration on the Z-1 and the Helios are identical.

--------------------------------------------------------------------------------

Q: Will the Z-1 work with the Spektrum DSM system?

A: Yes, with the right DSM module. You will need to order SPM1003 if you need the module and receiver, or SPM1101 if you just need a module. Your hobby shop should be able to get you either one of these.

--------------------------------------------------------------------------------

Q: If I install the drop-down wheel, will I void my warranty?

A: As long as you don’t damage the wiring while installing the wheel, no. Any damage during installation, however, will be considered “user damage” and is not covered by the warranty.

--------------------------------------------------------------------------------

Q: Is there a rechargeable battery pack available for the Z-1?

A: Yes. You can use KO’s pack for the EX-11 (KOP73010) in the Z-1. Please note that we DO NOT recommend a Li-Po pack for the Z-1 as the voltage output is above what the module is rated for and could potentially cause damage. Any such damage is not covered by the warranty.

--------------------------------------------------------------------------------

Q: If I have a service issue, do I send my Z-1 to KO Propo or JR?

A: Any and all Z-1 service issues, whether they are in or out of warranty, will be handled by JR.
