Lipos on commercial aircraft


I an going on holidays tomorrow morning and am thinking of taking the T-Rex 450 heli with me. Is there a problem with having lipos on the plane? Iv got 8 in the alum case. Your help would be appreciated.

Hey how are you? I would say probably not okay. I know here in the states that you can't have lipos delivered via airmail. Only way is by surface transport. A fire risk with a lipo battery is a real possibility, and fire + airplane full of people= Bad News. You might try calling the airline to see what they say, especially since you're in Australia. Good luck and Happy Holidays!

I flew several times last year and this year with them in carryon as well as checked luggage. Only on the last flight in July did someone say something, and it was the Xray guy at Tocumen in Panama, Panama. Maybe it was because I was carrying about 8 pounds of 6S2P batteries in carry-on luggage? He let it pass anyway...

I don't know what tomorrow's regulations will be. My luck is to usually find out of a new regulation on the way to the airport.

[/q]Scary. Not because of the lipos but because I bet he had no real idea that they were not something more nefarious disguised as lipos!

Lipos are ok as checked and carry-ons. You can still take your cell phone and laptop on board right? You should also be able to carry-on your TX, but you might get hassled over it. Just make sure you dont turn it on in flight, wouldn't really hurt anything any way.

Being a airline pilot, this stuff does scare the crap out of me. Only a matter of time before a plane is brought down from lipo's.

I would be concerned about it. Commercial items like laptops etc. might use lithium battery technology, but they have over volts, under volts and over current protection circuitry built in on the pack.
Our packs have no protection circuitry as we want max power. Also our packs are generally soldered to connectors at home etc. so there is little control.
Once I took a domestic flight from Melbourne with batteries as carry on. I told them at the check in counter about it and they couldnt match the description of my batteries to their reference chart. In the end the put the batteries in the hold for the flight.

True, but remember a year or two ago there were a bunch of recalls because of safety concerns.

For my money, I'd rather have them as carry on. If there is an incident, it could be better controlled in the cabin than in the cargo area.

Heh, yeah it says ammo can on it, has wires coming out of the packs inside, and they look a lot like plastic explosive wrapped up Then offer to show the guy the receiver, but call it detonator by mistake

In flight risk from Lipo air transport


Because of their potential, lipos should not be considered for transport in aircraft, in my opinion. The primary reason isn't whether they will or will not create an issue during transport, but what would happen if they did (risk).

An inflight fire in the cabin is one of the most deadly aircraft incidents, and has been responsible for several air disasters in the last ten years. In one, a person brought a small container of gasoline and a motorcycle battery in his carryon after off road riding, (yes it is true) it spilled in the overhead compartment and caused a fire, causing the plane to make an emergency landing just in time to avoid a crash. The other recent event was the Swissair in cabin fire was caused by the VCR used for inflight movies shorting out wiring, which spread to the point in a very short time that the pilots lost control.

An inflight fire spreads very, very quickly and cannot be controlled easily. It is one of the greatest fears of the flight crew. It puts many people who are traveling in great danger - who wants to be responsible for this, just for a hobby?

So, in my opinion, the risk is the real concern, not whether they will catch fire or not because of how they're stored or handled when traveling.

Funny, I have had air shipments of lipos from suppliers. There is no DOT or ORM labeling required for them.

A lipo, IF it goes off catostrophically, generates one fireball and that is it. Materials used in aircraft cabins are supposed to be fire retardant. And in flight fires spread no faster than anyother fire, and less so than most due to the nature of the materials used.

Yes, make sure your connectors are taped to prevent shorting, but otherwise no more dangerous than the people on board.

Carrying gasoline on board should never have been allowed. It is prohibited, even as checked (it DOES require DOT/ORM labeling).

The Swiss air crash was due to the type of insulation used on the wiring.

There have been a couple of reports of TSA screeners not allowing them on, but it seems very rare, and checked is OK.

If you carry on your transmitter, it may be subject to additonal screening, just like a laptop (removed from the case, Xrayed separately, and maybe swabbed). Plan on an extra 5 minutes for this.

The "lipo fireball" would probably be inside a carryon bag with flammable material in a compartment with other flammable material such as clothing, etc. The risk is not just the fireball against flame retardant aircraft material.
Imagine a Lipo fire in an overhead luggage compartment - would you want to be on the plane that experiences this event? Remember, your decision puts others at risk, it's not like burning down your workbench in your garage.

There already have been numerous close calls due to batteries and air transport. The attached summary of battery related incidents put together by the NTSB provides insight into some of these incidents. There currently is no restriction for these items, but if they continue to generate a concern about their risk, some limitations may be imposed regarding their transport.
