Wow, most enjoyable video posted for a long time. How do you land yourself whilst looking back at an F-86 landing behind/beside you ???

thx guys, haha... that was funny brk6! A difficult task for sure.
The camera records in 360 and the view selection is done post edit. It is both complicated and simple at the same time. Using the camera for raw footage is the simple part. The edit is the more difficult part.
I placed a raw version of that flight video on my YouTube for those interested to play back and move the camera around to their favorite scenes.
I think the raw format makes it difficult for people to see what you want them to see because there are just too many options as you can choose any direction at any time during viewing.The result is that if you only watch the raw version one time, you will miss everything that happened behind you, lol.
Here is the link to the raw vid. Its interesting, but I think you will see what I mean.

Thanks for the explanation WB. Must be a very nice lens to pick up all of that. Obviously the way to go if you want an first class video instead of those dots in the sky, non edited, crap -- yes I know I don't have to watch and I don't any longer than the five seconds it takes to realise what is coming. Nice F-15, sold mine as thought it marginal on 6S and I am not an 8S guy. Can you post pics/facts of your camera and its mounting set up ? It looks like it could pan but is that just your editing? Thanks.

There are 3 ways to record video with this cam:
1.) Make initial recording while live stream (viewers can actively move and select the camera view)
2.) Make initial recording, download video direct to internet.(viewers can actively move and select the camera view)
3.) Make initial recording, download to editing software, choose each fixed camera angle with options of other industry standard editing for stitching, picture quality, color, etc. (viewer cannot move the camera view)
I am still figuring out how to live stream, but even as a retired automation engineer, I have struggled at times to understand what the %^$@$%%^*%$ I am doing wrong. :Silly:
6S for me too. I can only guess that all stock power systems are not created equal. You are one of many to feel the F-15 was under powered to them. Mine has been so strong that it was my first camera ship with the Mobious, AND it has added servos for controlled drop tank release in flight. It is otherwise bone stock so I have no explanation??:Thinking:

While exchanging the stock fan with an FMS unit, I discovered the blunt joint of the inner walls of the intake ducting. Such design creates a lot of undesired turbulence. I made a simple 3DP part to create a sharp joint to improve the airflow. In addition, a nose gear brace was made. Both stl. files are attached.

Have you done any tests, does your "low-turb splitter" seem to produce better thrust? Does it change the sound?Marc flies FW & FL: AL37, MiG-29, T45,F4, A4, A10, F104 70 and 90, P38, Dauntless SBD, Corsair, B17, B24, B26 & P61, Lipp.P19, ME262, Komets, Vampire, SeaVixen, FMS Tigercat, FOX Glider & Radian XL.

I’ve no idea, why the intake ducts are designed with the “high-turb” rounded splitter. Just google “skin friction drag”.
If you look at well-designed wooden or composite EDF models with bifurcated inlets, you will always find such a design.

No tests with the A-4 yet. But I made a similar mod on the FW F-4, F-22, Lippisch, Avanti and L-39. On the last three, I did a ‘before and after’ comparison, and there is a noticeable higher top speed (GPS measured on the Lippisch). The question regarding the sound is hard to answer, I feel it sounds smoother at top revs.

The last three don't have split exhausts, what are you doing and what is "significant"?

It'll be easy on this one because it is larger, and the bulk of the Hardware can be housed within the thickness of the Engine Hatch on the FW A-4. I plan to get into one of these and do it.
