"A drone who has engines at 100% can not balance. You must have 10% - 20% to keep the balance.
MOSFET + PWM ... no difference in efficiency 0% - 100%."

"Have you considered some sort of folding feature to get the engines inside of the body?
If the body has to be made bigger, how does it affect drag in comparison to having the engines as you now have?"

"It looks so light flying ... because it is a computer animation.
This is a combo design using a vtol vehicle with helium inside:"

"You dont have a BEC.
You dont have a charger for the battery.
You dont have a GPS.
You ... like to have more then 1 battery.
You need a data link on 433MHz to get telemetry.
You need a laptop (and sunshade) to do map / telemetry / config in the…"

"The Seek Thermal camera is amazing in relation to the price. The problem is the lack of functioning drivers. "eevblog" has thousands of posts about different attempts. It's a mess.
If you've found working drivers please post a link here!
It would be…"

"It's a bit bizarre in priority.
In Sweden we do not have the resources to investigate all murders. "Less important murders" (wtf?) will have to make do with very limited resources. Have you been robbed? Well, we'll get to that later... or not.
But…"

"You're too close to the floor. You get ground effect.
Center of Mass contributes to "natural stabilization" = No, absolute not.
your drone is sure to work well. Test at 150 cm.
Your landing gear is likely to "grab" the soft ground = Drone overturn."

"There are very many who have misunderstood how the drone keeps the balance.
Many believe that a drone keeping the balance in the same way as a sailing boat. A large keel with a weight makes it stable. It is a simple and attractive explanation. But…"

"Design: Make wing big and "hide" the propellers inside the wing.
Is there anyone who have got this type of VTOL work?
The problem is that there is a contradiction in itself:Efficient flight as "drone" = large propellers, low pitch.Efficient flight…"

"so if one MOSFET burns ... 800USD *poff* ???"
"My drone for 250USD can do basically the same thing as "Mavic", some things better, some things worse. If I crash, I can turn to a forum to find out what went wrong and I can probably repair without major cost.
I do not need to guess what went wrong…"

"Long Duration Drones, usually looks like this (extremely minimalist slim design and gigantic propellers):

"Funny how the claim of 22,2V / 7000mAh is no longer on the site. :D
1000gram of battery and 500grams of "funny frame" + 4xmotor + "funny landing gear" and so on (not to speak of those cute little propellers).
There are drones with 1 hour of flight…"

"Theoretically, you should be able to eavesdrop on the SD card starting to write. On the first "data clock" + "write" signal or so. It starts some millisecond after the picture is taken, but it should of course be possible to compensate for in the…"
