You can adjust the rheostat little by little so your chopper stays centered, by unlocking the nut and turning. It's tricky, and it's REALLY EASY to mess this up.

$40, top speed of 20km/h (~12mph) and max height of 30m (nearly 100 feet...seems decent.

This one only goes up/down, turns left/right. No forward/backward action.

That's the dumbest thing I've ever heard of. Thanks for the heads up before I ordered! :Q

Well my dad and my uncle both got one. My uncle was flying his and it started smoking; it got sucked into the ceiling so he grabbed it by the tail and promptly threw it outside, where it basically melted from the fire or heat or whatever from the battery. It's now a smoking pile of debris. However he thought it was so terrific he's ordering another one :D

There are 3 rules to flying this bird:
1. For the first 5 flights, including the initial pre-charge flight, drain the battery 100%
2. Do not charge immediately after flying. Wait at least 10 minutes for the battery to cool down. For ultimate safety, wait 30 minutes.
3. Never leave it unattended when charging. When the red light appears, take it off. I don't think it has a trickle function; I think the battery can get over-charged which can lead to a fire later. That and if it does happen to catch on fire while charging you don't want it burning your house down.

Great toy as long as you're careful not to let it torch your home :D

it sounds kind of like lighting firecrackers in your hand and throwing them.
Its fun and scary and you get a rush but eventually you'll get a fuse quicker than you......lol

My complaint to the US Consumer Product Safety Commission was answered with a request for more information and a form letter.
Basically I said they should have better warnings and instructions about the batteries and charging process and possibly some sort of safety mechanism in the charger so it won't overcharge.

Of course, I expect nothing to come of it but at lease i did something.

Yeah, I'm sure they're overwhelmed just like the BBB, FBI, and so on. So many requests and complaints they can't even get to them all. And it's not the like the instructions are clear enough to explain that you shouldn't leave it plugged in or should let it cool between charging. The red LED on my charger has never lit up, in fact. It's a cool toy, but it definately needs some serious warnings. If they put in some charge protection circuitry it would probably solve the problem completely.

All you're going to do is ruin the fun for the rest of us. I'm sure that you think you're helping someone, but so did those safety-nazis who made it a law for kids unde 15 to wear a retard helmet while riding a bike. Or like those who pretty much banned anything that's fun, just because some idiot managed to hurt himself doing it.

Plug it in and go to bed, then complain to me in the morning

This is exactly what I'm talking about.

I think that people need to have some common sense. While I have the sense not to do that, I'm sure some idiot out there will, and smokes in bed, and smokes while replacing the fuel lines in his car, and wears flammable clothing with long sleeves while cooking, etc.

My contention is that it's a bad idea to complain to authorities to make everything idiotproof. This is a sickening trend in this country, and will only lead to everything looking like it's made by Fischer Price of even being banned outright.

Some uncoordinated oafy kid rides his bicycle without a helmet, falls, then his parents sue. Now every kid has to wear a helmet by law.

Some idiotic city slicker goes hiking up a trail on a mountain, doesn't stay on the path, falls, then sues. Now the trail is closed for everyone.

Someone dork goes ATV'ing, can't drive the thing, crashes it and breaks his bones, now he's pushing to have them banned.


My point is that making laws to accomodate the dumbest 10% of the population only serves to punish the 90% that were able to handle themselves just fine. Going by what these nanny-staters say, it's a miracle that anyone living before 1985 survived.

Your talking apples and oranges here.
If you ride an ATV unsafely yes you should expect to get hurt at some point.
If you charge a rechargeable battery overnight should you expect a fire come morning? I don't think so!
I agree with you to a point but yes there should be a safety cut off in the charger or a least some kind of warning on this thing.

P.S. Still learning and having fun with mine and no fires! ;)

Yeah, exactly. btw my charger's red light has NEVER come on, so I always have to keep an eye on it and unplug it when it's done charging.

91TTZ, your example should be more like you get home, park your ATV, and it explodes after 30 minutes from leaving the gas in the gastank. It's your fault you didn't drain it, so why are you complaining?

In the instructions, it says that it does have a safety feature to prevent destroying the battery. What this is, I don't know.

LOL! It's a self-destruct mechanism that prevents over charging. :)

Just some FYI.

I have a face to face appointment with the CPSC in 2 weeks and have to bring the remnants of the helicopter and all documentation and packaging.
My emphasis to them will be that the charger should have a safety cutoff switch to prevent overcharging and explosions.
I think it should also have some more obvious warnings about LIPO batteries and maybe some warnings to parents to supervise their kids while playing with this.

I will emphasize that the batteries are a great breakthrough for R/C hobbyists and that they are not the problem.

Also for the record, Radio shack is selling their version of this helicopter with LIPO batteries and guess what, it has a safety cutoff on the charger. So it's not like it's some big engineering feat to break, it's already been done.

The reason I am going through with the meeting is because I was going to buy one of these for my nephew who probably would have never read the instructions, plugged it in and burned the phukin house down.

As for me, I did not leave it on the charger for over 30 minutes and the thing exploded, nor did I leave it unnattended (unless you consider sitting in other room unattended).
I did not know to let it cool between flights nor to inspect battery after every crash because the instructions did not CLEARLY say to do so. That's all I think is warranted here. Have the manufacturer put a phukin sticker on the box with a warning or something.

"Destroying the battery"

and

"The battery WILL explode into flames spewing toxic smoke and will leave flaming fireballs of plastic all over your house" are 2 different ways of describing what WILL happen.

if anyone cares, i met with the US CPSC inspector yesterday. I pretty much just told them everything that happened, handed over the charred remains and some pictures. I emphasized that I think the problem lies with the charger not having a safety cutoff switch and that there should be more blatant warnings about the fire danger.

Also, I have been contacted by 3 other people who also informed me their helo burst into flames as well.
