In order to satisfy my bloodlust for the Inspire 1, at least temporarily, I've decided to try and maximize the performance of my IRIS+ w/ Tarot 2D and GoPro, especially for video and photo. I have the following upgrades to make and thought it might be useful to post the process and results here as I go.
- GPS/Compass: install a Ublox GPS + Compass Module with mast as a new primary GPS, retaining the existing internal GPS as a secondary source. I'll have a very similar mount to this. My current model is the + upgrade kit on the original IRIS, with the original covers and configuration.
- GoPro lens filters: I'll test all three of the filters here. I have high hopes for these, although I might need to make some adjustments for the filters to fit all the way on the lens despite the blue Tarot bracket. I'm especially excited to see if I can get some decent nighttime shots with my basic GoPro.
- FPV: The hit-or-miss aspect of flying photos and video without FPV and trying to frame shots at a distance with little depth perception is a fun and useful learning experience, but at this point I'd like more reliable outcomes. There's a very reasonable looking kit from Helipal here. With a splitter I'll power it off the gimbal power source exactly like the LiveView system does.
- Gimbal Dampers: I've read that the Tarot rubber dampers on the 2D gimbal are not ideal, so I'll try a couple stiffer replacements, especially with the added filter weight and FPV cables.
The idea is to get the low-hanging fruit first, so I'm sticking with my existing GoPro Hero 3 White and the Tarot 2D for now to see what I can get out of it before I consider a camera upgrade or 3D gimbal. If you have any experience with these modifications, I'd love to hear about your results.
