Guys, do we need to provide our scratch built model's make, model, and serial number to the FAA sUAS registration?

Here is one of the two demonstrators from the current JHAC Aircraft Improvement Project (AIP)

JH-P2A3 "Mini Wedge" UPA
JH-P2A3 Project flying wing UPA (5 min 6 sec)

The JH-P2A3 is the indirect derivative of the JH-22A SurfWing UPA. Although the P2A3 is 75% of the SurfWing base, it outplays the SurfWing with several innovations:

1. Stress-eliminating 3-piece integrated base airframe
2. Lighter empty weight (EW)
3. Lighter All Up Wieght (AUW)
4. Unnecessary components eliminated
5. Widened rear-central panel
6. Twin Inward-leaned vertical stabilizers
7. Smaller scaled control surfaces for more stability
8. Raked wingtips

In order to enhance stability and certain aerodynamic characteristics, this aircraft is equipped with twin inward-leaned VTs and raked wingtips.

Twin inward-leaned vertical stabilizers has these benefits:
1. Capture central flow & separate outboard flows
2. Increase central stability
3. Increase pusher prop efficiency
4. Separation of control surfaces

Raked wingtips do:
1. Eliminate tip stall
2. Increase glide ratio (GR)
3. Increase effective planform aspect ratio (AR)
4. Reduce induced drag
5. Smooth climb & stall

Here is one of the two demonstrators from the current JHAC Aircraft Improvement Project (AIP)

JH-P2A2 "Wedge" UPA
JH-P2A2 Project flying wing UPA (4 min 57 sec)

The JH-P2A2 is the direct derivative of the JH-22A SurfWing UPA. Although they both share the same base, the P2A2 outplays the SurfWing with several innovations:

1. Stress-eliminating 3-piece integrated base airframe
2. Lighter empty weight (EW)
3. Heavier All Up Wieght (AUW)
4. Unnecessary components eliminated
5. Widened rear-central panel
6. Larger vertical stabilizers
7. Smaller control surfaces for more stability
8. Slightly slower maximum air speed

After all the P2A2 is a rigid, super-stable flyer for both recreational and commercial operations.

Guys, if you do aerial photography/ videography (APV), can you suggest a common fixed angle for a mobius action cam on a flying wing?

Today, I was so content to open my long waited 4th Mobius Action Cam that I payed $80 on Amazon. Guess what, guys, tis a fake one shipped from Shenzhen, China that only worth $10 USD! The real MAC costs $80 USD and it is a much better HD FPV camera! As a result, I have to request a return with for that piece of !

Tips for getting Mobius Action Cams:
1. If you're in the U.S. or Canada, please buy all MAC related items from companies called "Novotm", "Spy Tec", and "Mobius".
2. If you accidentally purchased your MAC products from other companies, please check the shipping box and the product box. The genuine MAC has no Chinglish and any graphic on its box, it'll simply come with a cardboard box with a tag that says the company name on it.
3. If it happened to be shipped from a place out of the U.S., please return the item immediately after you confirmed that it is fake.
4. Genuine MAC has a darker, smoother, and much finer case compared to the fake one. Its lens is much larger than the lens of the faulty camera.
5. If you have downloaded the genuine MAC Mobius Setup app on your computer, you can notice that the setup wizard actually does not support the fake, and its board name will appear to be another brand (In my case, the board name is "Syntech" or somethin).
6. The fake product always have traits of very cheap and bad action cameras. It will also be very slow on powering and USB connection.
7. The fake MAC has file type...Continue Reading

Hi everyone, I've got a nice news to share with y'all. I'm currently starting my senior year Project Lead The Way (PLTW) Engineering Design and Development (EDD) project, which is about solving the multicopter problems in non-recreational Aerial Photography/Videography (APV) activities by designing a fixed-wing aircraft that is capable to meet certain standards. Detailed info coming soon! Check back with you guys later!

Oh Supposed I not to fly in high wind without a complete pre-flight check! Not solely junked my brand new JH-11A/P wing, but also my beloved C Lens Mobius Action Cam! I was just tryin to take some nice vids with my stablest controls ever, yet still crashed...

My first crash in the whole entire year, not because of the problem from either the transmitter or the pilot, but the wing's weakened motor mount that actually flew off the aircraft during flight. Pitiful.

Walked to the crash site and it was a catastrophe. The starboard wing snapped in half, the motor mount far reached from the plane, the camera landed head on and the case popped open, the battery smooshed... For such disaster, shall I pick up all of the remains with sadness and return to the pit with misery. Some quick paces left no triumph, I anxiously tried to turn the Mobius back to life; however, failure awaited.

Now what can I do? I definitely chose to fly my other flying wing, the big-o-trusty JH-22A SurfWing. Whatever to the blue sky and scattered lone clouds, I thought it was so D nice!

What type of specific aircraft does the aerial photo/videographer want? I want a specific answer please.

Can anybody tell me how to fix a computer problem? I recently upgraded my laptop from Win 8.1 to 10 and started using its exclusive feature, the Movies & TV app to stream all of my HD FPV aerial videos. It ran fine until last night, when I finally pulled off from my work and tried to watch some videos from my video library saved on the desktop, I found a very interesting thing: It stopped working! A small window popped out shortly, stated "Remote procedure call failed". Perfect. I developed some anxiety and started to search for solutions on Google and tried all of them, but non worked. I verified the other Win 10 apps and they work! Just the problem for "Movies & TV", even the other video apps work too! I wavered for several potential causes, and even thought some hacker is currently controlling ma unit! That seems overplayed, but still, I'm very concerned... I researched some info about the RPC, and it has to be in running position all the time, which makes a perfect sense for a grayed out, uncontrollable settings pane to exist.

So how would you solve this "RPC failure" on just one particular application on Windows 10?

This is urgent, please give me at lease a thought so that I can get my app working again in a short time. Thank you very much for stoppin by!

This is why you should choose fixed wing aircraft! over 80% less failure-destruction rate than the multicopter!
