You’re welcome. It’s a strange arrangement as the primary reason people buy a 920+ is the improvements found in the CGO-4, and previously with the 920 in the ability to use other cameras. Much, much better than a CGO-3+.
Unfortunately, some of what allows the 920+ to be flown using H programming is part of the program code in the CGO-3+. So the first thing that happens when flying a 920 in Typhoon H mode is eliminating all the superior benefits of the CGO-4.
I’m a little bit curious as to why UAV Toolbox is desired when flying a 920. The programming of the 920+ provides the ability to download maps, build waypoint flight plans on the ground, and pre-select camera aim points for each waypoint. You do lose GPS position tagging with the CGO-4 but to me that’s not enough of a reason to trade away 16mpxl for 12mpxl, an m2/3, 1” sensor, and sacrifice the zoom lens, variable bit rate, along with much greater control of the imagery.
Edit:
The OP actually answered that question in post #1; he wants to do mapping. With the 920+ mapping cannot be done using a CGO-4 as position data is not recorded by the camera. However, if he elected to obtain and use a CGO-3+ gimbal adapter mapping could be done in H mode using UAV Toolbox if the program supported mapping functions.
