Brownouts not to be confused with interference. 99 out of a 100 times, Loss of control would be from brownouts with the exception of the following.
Defective equipment
Very low-quality equipment
Bad install
Going out of range
blocked non line-of-sight signal loss.

Interference
Interference is very rare when frequency hopping is in use. Unless you're using a really low quality receiver or faulty antenna or you're standing underneath a cell tower with microwaves.
I Fly in two areas where there are cell towers very close by and one that's about 500 ft away and another one behind that about a thousand feet away. I also fly very close within 300 feet of a small cell tower. My planes will get as close as 100 ft to it. No problem unless you want to fly right up to the tower which I did with a drone which stop about 50ft from the Tower and return home. And that was with a really very low-quality receiver that was very prome to interference. In other places it did the same thing, the drone would stop freeze in flight in the exact same spot every time then returns to home due to microwave signals from the nearby cell tower 600 feet away. Does not do that with a different receiver, only the low quality or defective one.
Wi-Fi it's not frequency hopping so unless there's a very strong boosted Wi-Fi signal, it will not affect you. Pilots may mistake brownouts as interference. It is not. Interference was more common in the old days when Crystal receivers on one frequency...Continue Reading

What is the number one problem in RC.

In my opinion it would be brownouts on loss of control due to an inadequate power source. At least four planes that is my experience. Watching others and my own aircraft. Has not been a problem for my drones. Drones not having many or any servos for power surge causing a brownout.

This is an easy problem to fix. But because so many people think it is something other than a brownout they never do. They blame it on interference which is a rare thing with frequency hopping and binding transmitter to receivers preventing other transmitters from knocking you out of the sky like the old 72 megahertz radios could do if you were on the same Frequency.

Often all thatit is required to solve loss of control of your RC craft is a larger BEC or receiver battery. THAT'S IT.

SOME PEOPLE HAVE CHANGED OUT THEIR EQUIPMENT ALL TOGETHER AND THEN THEY SAY HEY I HAVE NO MORE BROWNOUTS. WELL THEY HAVEN'T HAD BROWNOUTS UP TO THAT POINT AND YES MAYBE THEIR SYSTEM WAS LESS SENSITIVE TO IT BUT THEY JUST SPENT OF A LOT OF MONEY NOT KNOWING WHAT THE REAL PROBLEM WAS.

I originally was a futaba user. I didn't like all the spektrum pilots who were losing control of their planes that were electric. Gas and nitro planes did not have that problem. That's because they are using receiver batteries.
I found that futaba was less susceptible but not immune to brownouts. Spektrum was more sensitive to a poor power source causing brownouts. Once I figured that out and fixed power source on all my scratch built 14 planes, thay never browned out after that. My 6 bind and fly planes never had an issue ever. That's because they were built correctly from the start.
So I know spektrum is a reliable radio. Although there are some who will disagree.

There are many things to consider when building RC Craft. Most important things are good power sources and good receivers. You may or may not put a lot of money into a plane or drone only to have it crash due to loss of control.
Some people go on and on repeating the same mistakes spending lots of money on new planes and repairs and a lots of time and not knowing why their aircraft is crashing and will continue to until either they give up or they find a solution to their problem. The majority of the time it is the power source that you're using. Not all ESC and their internal BEC can supply enough power to your system. And yes you could find a cheap receiver for very little money. But that is not recommended. Also buying used receivers can be a hit-or-miss situation. Myself I have bought receivers used and some we're good and some were not. I guess you could buy a new receiver and that could be bad too but that has not been my experience.
You must know your equipment. you must know how to program your equipment. You must do a range check. The range check will usually tell you that the system is working or not. Intermittent problems can be very hard to solve. If your plane loses control you need to rule out if you have a brownout power source problem. Where your power source is simply not adequate enough for your particular system. Some people go to the route of changing the equipment all together. That is the expensive way to go. It may or may not solve that problem for...Continue Reading

A long discussion about Brownouts Interference, BEC and Receiver batteries.

Brownouts not to be confused with interference. 99 out of a hundred times. Loss of control with the exception of defective or crappy equipment, bad install, going out of range or blocked non line-of-sight signal loss would be from brownouts. Interference is very rare when frequency hopping is in use. Unless you're using a really crappy receiver or faulty antenna or you're standing underneath a cell tower with microwaves. I Fly in two areas where there are cell towers very close by and one that's about 500 ft away and another one behind that about a thousand feet away. I also fly very close within 3 hundred feet of a small cell tower. My planes will get as close as 100 ft to it. No problem unless you want to fly right up to the tower which I did with a drone which stop about 50ft from the Tower and return home. And that was with a really crappy receiver that was very prome to interference. A non Spektrum receiver. In other places it did the same thing, the drone would stop freeze in flight in the exact same spot every time then returns to home due to microwave signals from the nearby cell tower 600 feet away. Does not do that with a different receiver, only the crappy one.
