Reliable communication with Graupner HoTT radios is no issue
for the Graupner GR-24 12ch 2.4 GHz receiver, suitable for any type of
application including large scale warbirds and large scale sailplanes. You will benefit from constant, real-time
information monitoring of receiver voltage, receiver temperature and signal
strength that is transmitted back to the radio without the need for additional
The dual, full range 2.4 GHz diversity antenna system continually
hops to the better antenna signal, utilizing the last antenna used for receiving
telemetry downlink transmissions. This ensures that the return channel data is
transmitted via the better positioned antenna, assuring you that telemetry
information is always available for a safe and secure flight.

I've really been liking these Graupner receivers (I have three 24L, three 16L and two 12L) and actually the whole Graupner system. I had an issue with one 12L that would not bind but Doug at Graupner swapped it out for a new one and now all ,my receivers bind first try. I must say the binding process is so much easier than my Hitec Aurora 9. The size and price of the entire line of Graupner receivers is terrific. Most folks around here fly Spektrum because that's what the local hobby shops sell. For the price of a Spektrum 12 channel receiver I can have two Graupners and change left over. Very satisfied customer.

Very good and compact receiver. It is doing a great job on my 20CC Dynamite Flite Chipmunk.

WORKS GOOD, I MOSTLY NEED 8 CHANNEL RECIEVERS BUT MY LAST PLANE NEED 10 CHANNELS. BEEN USEING GRAUPNER FOR ABOUT A YEAR TO REPLACE MY TRUSTY AIRTRONICS. SO FAR NO PROBLEMS WITH GRAUPNER.

I have not flown this as yet but if it is like my other receivers it will be fine. Binds easily with my MZ 24 Pro. I am presently building an 11 channel model and fitting servos as I go before sheeting etc. and hooking up to test. All responds well and program mixes work fine. Service was good as usual and I would recommend to anyone.
