Nigel, you’re concerned about the large video lag. How much is it to you ?
See my attached pic. It shows simultaneously the stopwatch in 3 instances:
- low is the actual time, when the pic was taken showing 00h00m29.69s
- in the upper left part is the image taken by the bird, shown on my tablet, showing 00h00m29.49s
- in the upper right part is the image taken by the bird, shown on a Tv connected to the HDMI output of the RC, showing 00h00m29.49s
As it can be noticed, there is a video lag of exactly 200ms btw the image shown by the tablet and the Tv, vs the actual time. I see this value as being exceptionally low, which shouldn’t prevent you in using goggles.
Try doing the same test and tell us what’s the result.
My suite is the following:
AC P3P (W323) sw 1.8.80
RC GL300B w/HDMI sw 1.6.0
App DJI Go sw 3.1.5
Tablet iPad mini 2 w/Cell 16GB sw iOS 11.2
Appreciate the info ... but still - If I was to look at doing FPV with a P3 .... I would install a separate FPV camera and Tx / Rx system. One that is designed with near zero lag and does not have to compete for carrier signal with commands etc.
I have such items on the bench ... as well as goggles - all from usual FPV world.
Hi Nigel, my name is Mike and I don't post often but read a lot. Been flying RC since the late 70's. I have a P3A (purchased 11/2015) and a Spark (purchased 12/2017). with each RC i use a parabolic antenna. For fpv and my P3A I use either my DJI goggles or FatShark Dominator V3 via the HDMI output on the RC when using my galaxy S6. When using my iPhone7 I can use either, by themselves or both simultaneously(one for a friend) with a lightning to HDMI cable connected to the phone and the HDMI from the RC to the other. through my experience, I have yet to experience a lagging issue with the exception of losing the signal completely because I was not paying attention and flew behind a hill. my bad. I fly mostly in the foothills of the sierra mountains and Folsom Lake area.
I too at first was very leery and afraid of the FPV, nauseating as a matter of fact. I used the grid lines in camera settings to help orientate my position to objects I was flying around. and knock on steel, because it's harder than wood, I haven't crashed... yet. Just trimmed a few leaves from bushes.
Anyway, don't be afraid, be patient with yourself. Flying these things is a skill learned and with all this cool technology... well that's just icing on the cake.
You might consider slowing your controls down a bit. Lower the responsiveness some. Notice some more abrupt changes than I personally would like in my system.
