I have GL 300C and GL 300F controllers. Which one is used for a P4? Neither one links to the P4 aircraft. The DJI Go4 app comes up with a Mavic pic when it says pick your aircraft but then states P3 and the DJI GO app comes up as a P3 pro? I'm clueless but that is norm for me... Dennis
Hi, thank you for bringing this query to us. The GL 300C can only be linked to the DJI Phantom 4 while the GL300F can be linked to either P4/P4A/P4P yet you need to choose the aircraft type in the APP. RC setting →advanced setting. Also, you may try to relink the P4 on both controllers since the DJI Phantom 4 is compatible with both RC. You may refer to the tutorial below. Please keep us posted. Thank you!
