Our most affordable 2.4GHz full range receiver with built-in
telemetry, the Graupner GR-12L 6 Channel receiver is small sized and
lightweight, lending itself very well for small park flyers, lightweight hand
launch sailplanes, helicopters and multirotors. The ultra-low voltage
requirements of the GR-12L allows it to operate on a single-cell LiPo making ideal
for DLG gliders.
The GR-12L provides real-time bi-directional data
transmission of critical system health datalike temperatures, receiver
voltage and signal strength using the Graupner HoTT protocol providing you with
telemetry information you need for a safe and secure flight.
- Up to 75 channel hopping for extreme operating reliability
and immunity to external interference
- Compact and lightweight
- Front load servo connections for easier installation in
- Digital SUMD, SBUS signal output providing connectivity to other vendors flight controllers
- Selectable frame rate of 10ms or 20ms for digital or
- Fail Safe and Hold function
- Low power consumption
- Wide voltage ranges from 3.6V to 8.4V
- Built-in telemetry for temperatures, receiver voltage and
receiver strength monitoring
I bought two of these to put in a bnf I bought and a small foamboard plane I built. They work perfectly. Six channels, passed range test, very responsive, no issues what so ever... What more could you ask for? Note that I use a Graupner MZ24 transmitter if that helps. Not sure if this is the best price you could get, but these are certainly not knock-offs, otherwise I'd roast them. Identical to the one that came *free* with my transmitter. Buy with confidence as long as you know what you are getting and what you need.
I also used one for the PC interface to my simulator and it worked just fine. When 6 channels will do (throttle, aileron, rudder, elevator, then perhaps arm and flaps for the other two?) this one will meet your needs. Clear skies!

SUMD works perfectly.
Works great for me. Using a mz-12 with naze32 SUMD to ch. 6

This is an excellent receiver at a good price. I have more than one. I am using this model in both gliders and powered airplanes. Never a single problem. The built-in telemetry is great. Small and light. Highly recommended.

5 channels + telemetry
I received this receiver with my mz-24 radio. I only wish it was a true 6 channels receiver when using telemetry. I fly electric and I always use telemetry to monitor voltage of LiPo battery that powers my airplane. Channel 5 of this receiver is used for telemetry, so I am left with only five channels and that is not enough for my airplanes that have retractable gear and Flaps. Other than that it is a good receiver. I use it in my only airplane that has no flaps and no retractable gear. I took one star off because telemetry is on channel 5 instead of being on dedicated telemetry channel like it is on 8 channel receiver that also came with my transmitter. I received 4 receivers with my mz-24, and 3 of them have telemetry on channel 5, so I cannot use them on my other airplanes.

Great receiver! I use them in Quads, Sailplanes, and large foamy's like the Flex Innovations RV8 and C170. SUMD port makes it easy to interface with controllers! Recommend buyers upgrade to the latest firmware to make use of all the features!

I recently bought A MZ-24 transmitter and several receivers. so far I have been very happy the quality is very good and I would recommend it.

So far I have used this receiver in 3 park flyers. I have flown in small areas as well at our flying field with more space and have found the receiver to be flawless so far. I only have about 30 flights to date but happy with the performance thus far. Binding with the radio is simple and have yet to have any issues with range testing. The single antenna works well with park flyers but it would be pretty short if you are using in a larger plane trying to be away from other electronics. For my larger planes I have installed the dual antenna GR 16L but the GR12L would probably do the job.

THIS RECEIVER IS AN EXCELLENT FIT FOR MY NEW FT SPARROW. IT PAIRS NICELY WITH A DX6. FLITE TEST HAS EXCELLENT PRODUCTS I WOULD RECOMMEND FOR ANY SKILL LEVEL IN THIS AMAZING HOBBY. FLITE TEST ALSO, THROUGH YOUTUBE, HELPED ME WITH PROBLEMS I MAY EXPERIENCE WITH MY AIRCRAFT. THANK YOU FLITE TEST!

SMALL, BUT FILLS THE NEEDS FOR ANY BUILD. HAS THE DISTANCE NEEDED FOR FLIGHTS, AND FILLS ALL THE REQUIREMENTS NEEDED FOR THREE AND FOUR CHANNEL PLANES. I WILL BUY MORE AS NEEDED FOR FUTURE BUILDS. BEST BUY YET LOVE THIS RECEIVER. THANKS FLIGHT TEST.

CHEAP BUT WORTH EVERY PENNY
I HAVE BEEN USING THE GRAUPNER 16L WITH THE TWO ANTENNA LEADS BUT IN A CRASH AT LEAST ONE OF THE LEADS ALWAYS BREAKS OFF. GOING SMALLER WITH A SINGLE ANTENNA IS THE WAY TO GO WITH THE MINI'S LIKE THE ARROW AND THE VERSA WING. EASY BOND WITH THE TRANSMITTER AND WITH ONLY THE THREE LEADS THROTTLE LEFT RIGHT ELEVON IT IS MORE THAN ENOUGH FOR THIS RECEIVER AND BECAUSE OF THE SMALLER SIZE FITS EASILY INTO ANY CLOSE QUARTERS. I THINK I LIKE THE 12 BETTER THEN THE 16L ESPECIALLY FOR THE MINIS. NOW WHEN I MOVE UP TO THE MORE DIFFICULT PLANES I.E. THE CORSAIR AND THE P51 WITH MORE CONTROL SURFACES I KNOW THE 16L WILL BE THE WAY TO GO.
