The most common problems seems to be with LiPO or lithium batteries are with e-bikes fires but not limited to e-bikes. The bigger the device or battery the larger the risk.


I got to say the most scariest part of owning LiPO batteries besides the fire hazard is the fact that I ride the elevator up and down with those batteries while you're temporarily trapped inside the elevator until the door opens. I know there are some safeguards for elevators but that's more for not the elevator stopping on the floor that's on fire. If my battery is going up in smoke while I am in the elevator is the elevator going to stop and the door open or am I going to just have to ride it out. I'm guessing it will stop and open the door. It can happen in my vehicle too but I can stop and get out.


This is not fiction. This stuff actually happens and yes people get burned buy lipo fires and harmed by smoke annihilation and sent to the intensive Care unit. And yes some people do die.

I'm more afraid of the smoke myself cuz I have gotten my wiff of that smoke and it was bad. Wasn't trying to smell it but just was the lingering effects of the aftermath during a damaged lipo fire test outside in a completely open outside area.

I keep my batteries outside so not too much a problem as far as smoke damage indoors. That is if windows and doors are closed neighbors included.

Just thought this was worth mentioning although there's going to be some who wish I didn't. I don't care about them. Greedy bastards.

LiPO batteries are common. They used in cell phones and computers and electronic devices as well as our RC devices.

The LiPO batteries used in the RC industry often don't have the kinds of protection that the cell phones and other device batteries have. Don't compare the two cuz they're not the same. Yes cell phones do catch fire but not that common.

It is well documented that lipo batteries are a fire hazard. Lithium batteries also. Life batteries not as much. HOBBY STORES, LIPO LITHIUM BATTERY FACTORY, HOMES, VEHICLES AND MORE HAVE BEEN DAMAGED. Yes they have been deaths also. Unfortunately the dead can't tell you about it.

The advice normally is do not store batteries fully charged because they are at a higher risk of catching fire.
DO NOT STORE (keep) DAMAGED BATTERIES.
Do not store batteries in an area where materials can catch fire and smoke damage can occur. LiPO fires give out a huge amount of smoke and yes it is harmful if not lethal. So do not inhale. Not only does water not put out Lipo fires but can actually cause a LiPO battery to ignite. Charged Lithium metal will ignite in water. Sand is a better alternative. Water can be used to put out some other materials that have ignited, but not all.

Batteries that are at storage voltage of 3.8 volts per cell still can catch fire but are at a lower risk of doing so. Try not to get confused with stored and storage voltage. Stored is the location. Storage voltage is the state of batteries charge. For...Continue Reading

...I have heard many times about the counterfeit or fake products you can buy usually from China on eBay. There are many claims of different items being counterfeited. Battery connectors, receivers and so on. 1 item in particular would be Spektrum receivers which I had bought a lot. I have heard claims made that the fake receivers have different screws on the case or a case that's more transparent. Frankly I prefer a more transparent case because there are LEDs inside. Another one claimed of markings inside the receiver. Also they will say that the receiver has been out of production for quite some time even though it is still available from other retailers. Non of this stuff means nothing to me. 1 claim usually made by people associated with Spektrum / horizon hobby is that people having problems with brownouts that is airplanes all of a sudden losing control crash into the ground are fake. They claim that if you did not buy it from horizon hobby or a reputable company then it's a fake.
A lot of RC pilots gave up on Spektrum and change manufacturers. I did the reverse. I was using Futaba and somebody gave me 4 Spektrum receivers that he was no longer using because he changed to Futaba. Another person gave me my first Spektrum transmitter that had a defect and I fixed it. Years later I bought 1 receiver and 1 transmitter from horizon hobby. I also bought used about 7 of the bind and fly planes that some have Spektrum receivers in them. All the other...Continue Reading

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 they are 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 range checks. 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...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.

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.

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.
