I had gotten the impression that you were making the distinction between FAA rule and law and that the rule is not as binding. I completely agree on using antennas to improve performance.

The fact that it is an FAA “rule” may make it worse for those breaking the rule. I am a relatively new drone owner and not very familiar with FAA, but I work with the FCC regularly including enforcement. Their rules allow them to do warrantless searches and administer fines. I would suspect the...

Ok, somebody has to ask. What is a “Ute”? I was just watching My Cousin Vinny a couple of weeks ago and I couldn’t resist.

Not true. A typical yagi consists of a driven element which is a basic dipole with a reflector and one or more director elements. It’s my understanding that the stock antennas on the controller are basic dipoles. As long as the spacing is correct, they should perform well. The only issues I see...

My wife has been into quilting for the last few years. I have requested a quilted landing pad. The new “thing” with blankets is adding weights. I suggested a few weights sewn in to keep it flat and stable. We’ll see if she makes me one…

You’re absolutely correct on the shading from the tablet. Maybe you can find an extension for the antennas, a bracket to place the tablet below the controller.

I live in south Louisiana and alligator hunting is a business. Gators have not been ‘endangered’ in decades. I live on the edge of a large swamp with a lot of alligators in it. One of those clowns on TV hunts this area ( he also owns an alligator farm and isn’t as dumb as he comes across on the...

They transmit and receive simultaneously on different frequencies. So you can have interference on one and not the other. The receive frequency on the controller is the transmit frequency on the aircraft, and vise-versa.

It’s been mentioned already that this mod is probably illegal. I believe the FCC limits power out at the transmitter to 1 watt. There are ERP limits as well. Does anyone have the FCC ID for this amplifier. It would have to pass Part 15 regulations. These ID’s are searchable on the FCC website...

Lithium-ion batteries do not contain lithium in a pure volatile form, like the energizers in the video, and shouldn’t react with water in the same way.

Actually, lithium-ion batteries contain very little lithium. As I mentioned prior, I am no expert on lithium batteries, but the construction information is easy to find online.

You’re right. A preamp will increase all rf signals above the noise floor and increase dynamic range which effectively lowers the noise floor. Too much gain and the receiver can be overloaded or saturated easily though.

Lithium -Ion batteries do not have the sheet of lithium/metal that reacts with water. Those are common AA ( non rechargeable) Energizer Ultimate Lithium type batteries.

From what I have read, and I am no expert on this, lithium-ion batteries contain little or no lithium metal which is what reacts with water. I have a Mavic Mini which uses Li-ion batteries. Are other types used in different models?

Would a handheld scanner that covers aviation band be suitable...
