Please note that the GR-18 receiver/ flight controller combo is only compatible with Graupner transmitters. This Product comes with both the MZ-12 Transmitter and the GR-18 Receiver/Flight Controller.
GR-18 Receiver Overview
Engineered with an integrated flight controller for multicopters, flybarless helicopters and 3 axis stabilization gyro for airplanes the GR-18 is the most advanced 2.4 GHz receiver ever made by Graupner.
Setting up a multicopter, airplane or helicopter is easy and instantly done over-the-air on any Graupner HoTT transmitter. No computers, programming boxes or complex wiring are needed to set up your model on the workbench or at the field.
Need to make a change or adjustment? Just land and use your radio to make the changes on the spot! Build inside the GR-18 are a range of telemetry sensors to assist you during flight. Whether you need to know your altitude, battery voltage or signal strength the GR-18 will monitor any user desired parameter and notify you in real-time about any condition that requires pilot attention.

MZ-12 6-Channel Transmitter Overview
This is Graupner mz-12 HoTT 2.4GHz 6 CH transmitter. It is Graupner’s unique telemetry technology in 2.4GHz
signal protocol that supports bi-directional data transmission and gives user real-time information.
The use of up to 75 frequency hopping channels ensures extreme operating reliability and immunity to external
interference thanks to optimized frequency hopping broad channel sequence. Through the telemetry function,
you may check receiver's consumption voltage, temperature and also program the telemetry function. By using
optional sensor, brushless control + T ESC or HoTT sensor module, you may get the real-time data such as RPM,
voltage, current, temperature, and warning. Graupner mz-12 combines an easy-to-use design with the
incredible control of Graupner/SJ HoTT technology that is an ideal choice for anyone who needs high quality
6 channel radio.

Nice Radio sent promptly,packaged well. In the process of installing in versacopter. So far support has been lacking, have tried to contact several times with one note saying they would be back with me shortly, still waiting almost three weeks now.would like to purchase more products to turn versacopter into an fpv machine. I will wait till I can get some support to make sure I have guidance to purchase the parts that I need to fit my needs. Terry Antioch Tn. Unknown on 22nd Jan 2017
I purchased the Graupner MZ-12, GR-18 Combo as my first entry into the RC hobby. I did some online research of various comparable brands, but settled on the Graupner based on the price, reviews, and the fact it came as a combo T/R package. Assumed I could use the GR-18 as the receiver for my Tiny Trainer build. Build quality is good, gymbals, switches, buttons all have a solid feel. The MZ-12 manual is pretty comprehensive, but takes some time to read and absorb all the options. Some YouTube videos were easier to follow.
The GR-18 initially sounded like a good deal, but when I connected to my servo's, only channel 1 Throttle seemed to work, nothing from Rudder, Elevator, etc. At first I thought it might be defective, but after doing some reading, it seems this model (S1019) only supports multi-rotor, no option for fixed wing operation. Wish that had been more clear in the description. Fortunately I purchased a GR-12L receiver separately and it works fine.
Some Youtube video was a big help setting up the servos, D/R Expo, sub-trim etc. The maiden flight test went about as well as expected for a first time out. Only flew out to a range of about 500-600 ft, but the radio connection seemed rock solid. Battery life on the transmitter seemed a little short using the standard AA cells, I substituted Energizer Ultimate Lithium for longer life.
Separately, I purchased the Graupner Smart-Box to monitor the receiver telemetry and GPS date from a separate module. The manual for the Smart-Box was 2010 version, almost worthless to understand how to get everything up and running. Contacted Graupner for an updated manual, but the response said no updates were available. However online I found a 2012 version twas a bit more helpful. I'm still trying to get it all sorted out, but for the most part its working.
GraupnerUSA website is a bit weak for finding updated manuals.
Otherwise a solid system, I'd buy it again and will consider it seriously when I eventually upgrade to a more advanced system. TechGeezer on 1st Sep 2016
I grew up in the R/C world, my dad owned an R/C store/track and building RC cars with my dad is literally the earliest memory I have. I was overjoyed years later to rediscover my childhood passion through R/C quads. I was amazed with the simplicity of the versacopter v2 build flight test put out. Over the course of a couple weeks, any extra dime I had went into getting the exact build featured in the video. Had my first test flight with amazing success (thanks to training on a nano qx first since this was a whole new ball game for me). After many great flights in my back field I started really trying to educate myself with every feature my MZ-12 and gr-18 had to offer. One of the first things that I was scared to find is the failsafe of the trans/recv is preset to hold the last input if the connection is lost... For an amateur geared product that seems like a fatal thing to leave default. I quickly reprogrammed it to shutdown if transmission is lost. Took it out and tested it multiple times before attempting a solid flight again. I battle anxiety quite a bit and so I wanted to be darned sure if that connection fails, my drone is going to the ground. Fast forward a couple week or so, got back to feeling safe with my drone and took it out on a Sunday night to cheer up after a rough weekend. I was flying with a full 4s 1800 mah fresh battery. At about 50 feet (about as high as I feel safe flying at for line of sight) I lost response to the drone. It started flying up and up and then also away. There was no wind, I had the throttle almost near cutoff but I wanted to try to get it back safely and not totally cut the motors. Despite my best effort it simply wouldn't respond to any input I gave it. When it was at the point of I knew I couldn't bring it back I turned the receiver off, and at point I lost it behind a tree line. I don't know if it dropped, I have no way to find it. I've contacted all my neighbors with no results. So here I am having tasted the joy of flight, and watching with childlike dread as my little buddy drifted off anxiously hoping I didn't damage someone's property or (even worse start a fire). I'm not totally sure exactly what happened but I do know the drone should not have kept flying if it was getting poor response. Also just for salt in the wound after my drone had flown away my transmitter decided to tell me that it had a low battery. Maybe that had something to do with it, idk I'm still just a rookie.
-Great simplicity to get started
- BE SURE TO SET YOUR FAILSAFE TO TURN THE THROTTLE OFF
- I don't know if I'd trust another one, if I'll even be able to afford another build any time soon Chris Wallace on 14th Jun 2016
Don't bother with this receiver if you have a plane. The receiver firmware comes pre-configured for copters. You would need an extra cable with some doohickey on it to change the firmware so you could fly a plane with it. The software to do the change doesn't work. Unknown on 4th May 2016
I purchased this combo for my Versacopter V2.. It's almost like this Tx/Rx setup was made especially for the V2 quad.. Setup was a breeze and after watching the build video with Josh.. Also I truly recommend watching the video with Josh and Mannie.. The step by step approach to this Transmitters system even makes it easy for an old man like me.. I would highly recommend the Graupner Mz-12 and Gr-18 comb to Everyone.. TAB Thomas Brewer on 11th Apr 2016
I bought my Versacoper V2 first and then patiently waited an entire month for this item to be stocked ... it never happened. I was promised over and over that it would be in stock soon and that I would be notified. I never received such notification and finally gave up and bought a transmitter/receiver elsewhere. This package is highly recommended in FT's videos as a perfect set up for a noob like me, but I think this combo should be removed from your site if you can't provide it. Unknown on 30th Mar 2016
Bought this with the Versacopter kit. It easy to use and built well. Everything is already paired together, so the plug it in and fly! Well actually set the axis first before you do that.
One bad thing I'd have to say is the instruction booklet has nothing in it about multi-rotors. Also some of the directions were still in german. Thomas on 25th Dec 2015
