Graupner 250Q Alpha FPV Troubleshooting help


New member
I recently purchased the Graupner 250Q Alpha RTF FPV combo pack from the store along with Fat Shark Attitude V4 goggles. The manual says the copter should be already set to broadcast FPV with the included Helistar FT591 set to group D and ch4. I replaced the included dipole antenna with an Immersion RC Omni R antenna to match the one on the goggles but the screens show no picture after scanning and locking on ch 4. Fat Shark troubleshooting says this should most likely be an issue with the camera or transmitter.

Any experiences with this transmitter and camera that came with the quad? Suggestions for possibly replacing the transmitter and camera?
