1ea Graupner HOTT GR-18 receiver used in excellent condition I have 4 and realized I don't need 4.
It can be used for multicopter when flashed. These are the receivers that Graupner is putting on their line of Quad racers.
$80 each manuals and info included. I trashed the boxes.
I had these mounted on a Goblin 570 and a Trex 800, setup and adjustments are made via the radio.
look closely and you can see the gr-18 mounted in place
sold one . one to go!
you will need to download this manual
It took 27 years, I CAN FLY UPSIDE DOWN!!!
