Default Flying with lipo's

Shipping lipo's has become more difficult of recent times.

I travel from Canada to Texas every Christmas to visit family. If I have lipo's shipped to their house and then bring them back in my luggage, I'm assuming I will be offside off FAA rules.

Flying more, crashing less. Feels great!

Default Sort of...

The brushless was on it when I bought the SC used. It flew 'ok', but not great.

It has an emax BL2215. It was propped with an APC 9x9E off a 3S pack. Needless to say, that wasn't a great combo.

So I went down to a 9x6E which was better but still didn't feel like it had enough authority. I planned to swap it for a 9x4.5 but yesterday I picked up a GWS 9050 which, according to Heads Up RC produces 31 oz of thrust on 16A vs. 30 oz on the 4.5 or 29 oz on the 6 at 18A

The GWS prop also has a much smaller hub profile than an APC prop which means I can use it on my prop saver. Our 'field' has 3" long grass so,the prop saver is called into use far too often.

Flying more, crashing less. Feels great!

Depends on size of largest LiPo and total weight of LiPos. There is a limit on what you can take on a commercial airliner.
I forgot the exact rules, but you can look it up or call the airline.

throw a 10x5 on it and dont use full throttle a lot.

heads up ships to Canada and has 1800mah 3 cells for $15.95 right now.

from my understanding, you can carry basically anything as long as it is in checked luggage rather then carry on. I flew to Oregon from work and was able to take all of my work tools on the plane, even though they did dump them all out and take my climbing gaffs all apart.

but call the specific airline or check their website. they let you have a cell phone and that uses a lithium battery.

slow stock prop reversal. it flies! easily! 543 watt dual motor bipe slow stick. push-me-pull-you. 242 watt 3 channel slow stick. 365 watt mini ultra stick. 415 watt mini contender. 810 watt ultra stick .25e. 220 watt alpha 450 sport (retired).

Check this link:

http://safetravel.dot.gov/definitions.html

It defines the type, handling and size permitted on commercial flights.

When I last flew to Hawaii the rules shown still applied (April 2013).

I've used Heads Up once (and they were great) but they won't ship batteries to Canada. This is the same for any US online source I've found.

I found the FAA regulation. To be shipped properly requires very specific conditions. I know I could comply but I have no confidence that so an eager baggage inspector wouldn't create an issue.

Would hit the 25g limit of allowed ELC: 2200/1000x11.1=24.42g

I gotta say the cost of lipo's in Canada is ridiculous. A turnigy 3S 2200 pack on amazon.com is $23 but can't be shipped to Canada.

On amazon.ca the same battery is $60!

And it's only slightly less at the LHS.

Out of curiosity, what would these (Heavier, larger, lower voltage) A123's cost in Canada, since they have zero fire hazard?

http://www.voltmanbatteries.com/serv...1-dsh-A/Detail

I've got over 100 of them in my various models. They are good for about 35-40 Amps max per cell, and at that current, their output voltage per cell is about 2.8 VDC. But they can be charged at any rate your charger can put out, they can be charged in the model in about 15 minutes, or less. No puffing, about all that will kill them is being discharged below 2 volts per cell. They can be safely stored at any value of stored milliampere hours. They do last for a long long time.

They don't work well in foamies, though, to big, and to heavy. It takes four 2300 Mah A123's for 10 ounces total to replace a three cell 2100 Mah LiPo.

I found this chart:
Interesting, but pretty heavy as you say.

http://forums.openpilot.org/topic/84...ipo-batteries/

this page may be of some interest.

if you go by the 8 grams is equivalent to 100 watt hours and you can't exceed 25 grams, 300 watt hours, then a 5000 mah 3 cell would only be 55 watt hours.

so basically, you can pack as many spare batteries as you like in your carry on baggage as long as they are all under 100watt hours is the way I read it.

Thanks for that link Hay, I hadn't interpreted the rule that way it makes sense to me.

Hmmm, time to call Heads Up!

I've never carried more than 2-1800mah 11.1v, 2-2200mah 11.1v, 2-1600mah 7.4v lipo's along with my spare lap-top battery. The lipo's were stored in lipo bags, plug ends taped and placed in my carry on case. The lap-top battery was just laid in the case.

I've also traveled several times with my lipo charger and several 9v, re-chargable Nicd AA and charger stored in bags packed in my main luggage. Only once was I ever held over due to inspection. It was in HNL (Honolulu) in 2010.....rookie TSA inspector. Asked a dozen questions and delayed us more than 30min.....all because he did not understand the weight to watt carry on issue.....we made our flight ok thanks to an experienced inspector who knew the law.....lol

The batteries have never been a big issue, but the heli's (built two 450's for friends), guitars, amps and various gig bags cost me a $$ton$$ to travel overseas with, require special treatment and a real pain to get through airport baggage handling.....good thing most of the gigs I've done on the islands at least covered the travel cost......!
