"The coolness factor has warn off now that COTS drones exist. Like you said, DJI has locked up the market for LOS drones. It is even cheaper for commercial operators to buy a preapproved drone than it is for them to get their Frankenstein drone…"

"I have not decided whether to register or practice civil disobedience. One violation could have significant impacts if they start enforcing it. But honestly, my only personal qualms are being on a government list and being on a public list.
I don't…"

"This is not as awful as it seems. AMA seems to have 'won' on several points. For example: community orgs that fly over 400 ft or use FPV. Also AMA is claiming that your FAA# is not required on your aircraft if you already have an AMA number on it,…"

"Your RTK GPS sounds great! It makes sense that it can be priced similar to other GPS because the hardware differences are minimal, but we all know that engineers need to eat too. RTK GPS requires a lot more engineering!
One point of these articles…"

"I'm glad that the online article does not contain the error. It restores my faith in peer reviews."

"The math in that paper may be horrible. The 60% figure is wrong. it should be (5.6 - 5.0)/5.0 = 12%. It would not surprise me if other numbers are wrong too. Their assumption that velocity does not suffer from this problem is also incorrect. If you…"
