Ok so I have now been able resolve all my issues I had with the Epson BT300 and to be fair part of the issue was with DJI and not Epson as I initially had assumed.
So just to summarise;
1. The initial problem I had with vision, that is being able to view the drone on a bright sunny day was resolved when I purchase a pair of sun shades from Rochester Optical. I have a P4 which is white - so contrast was originally poor. The Rochester shades are darker than the OEM that were shipped to me. Subsequently I understand that the Drone version of the BT300 will come with the Rochester shades. I also found that the recent DJI app update provided better clarity in terms of contrast than the original DJI app on the Moverio app website. These two improvement now give good vision.
2. The original DJI app which was available for download from the Moverio website when the BT 300 was first released suffered from video lag - which was just awful. The newly issued app now climates this issue.
3. Some P4 owners had experienced poor picture stream (pixilation) since DJI issue firmware update V1.8 for the RC - I think this was back in Oct or Dec time last year. Rolling back to V1.6 has removed the problem and I am now finding the picture stream is good. I will wait for the next firmware update to resolve the bug somewhere in V1.8. Not all users are experiencing issues with V1.8 firmware, indeed if I use my iPad to view the video stream it works perfectly well with RC firmware V1.8. Reading various blogs on the internet is does seem the issue with V1.8 firmware has affected generally non IOS control units (android etc.) and also strangely those using less powerful iPads have experienced issues. Anyway, rolling back resolved the problem.
Having now carried out a test flight everything appears to be good (it’s taken a few weeks of head scratching to get there). Having ironed out the initial issues above my view is that this is a very good product and I am now very impressed with what I have.
