I have been keeping an eye on ebay, but haven’t found anything, It’s for a christmas gift for my boyfriend. But gosh these things are expensive! Anyone have anything?
You can try craigslist but be careful
I just bought a micro Walkera 4#3b RC helicopter and a Walkera LAMA 2-1. I was curious to know how long a 3.7V 400mAh Lipo battery takes to fully charge up?
Depending on how much you drained your li-po battery, will vary on the charge time. I hope you do not drain the battery all the way down because if the battery is below 3.7 Volts, then you could risk blowing up the battery, or damaging it. But typically it takes about 45 minutes to 1 hour to charge the battery (1 cell batteries do not require balancing).
You have a li-po battery, and the charger should come with a indicator that has a red light indicating its charging and a green light that turns on when it is finished charging. Not having an automatic cut off charge is dangerous and could result in a fire. Refer to the manual if you still have it. I recall testing the Walkera product, and its suppose to have a light indicator. If not, run the helicopter for about 7 minutes (average tested flight time) and then charge it for about 45 minutes.
I own a battery charger that came with a radio controlled helicopter. This charger does not have the, [ UL ] Underwritter’s Laboratories, seal of approval on it, like all of my other battery chargers. The instructions say that you should leave the battery pack on the charger for one to one and half hours to get a full charge. This battery charger gets too hot to touch with bare hands after only a half hour. These things are fire hazards!!! When I use this thing I have to set with it and use a stop watch, unplugging it every half hour before it gets too hot. If a person who owns one of these plug-in Chinese battery chargers were to leave it unattended I sure it would start a house fire. When is the United States going to force the Chinese manufactures to stop selling unsafe products, and comply with the safety regulations that American companies have to go by?
manufacturers they can sell what they want.
It is your choice to buy it. If they do not make good safe products, people should choose not to but it.
do not blame the manufacturer, the consumer should not buy a bad product. caveat emptor ( let the buyer beware)
It’s time to soar the great blue skies with the HX Dragonfly 251 remote control helicopter. This life like helicopter is powered by two electric motors and can fly up to 100 feet high at speeds up to 12 mph. Soft, gradual control response and stable hovering characteristics also make it one of the easiest R/C helicopters to fly! The digital proportional radio system with 2 channel control is easy to learn making it suitable for beginners. The fully functional remote features left, right and up, down controls and allow hovering at any altitude. The main frame and body of this durable helicopter are constructed using ABS crash resistant plastic. Features: Full function 2 channel radio control Twin electric motors Altitude and rotor speed control Flight stabilizing system Super lightweight airframe Brake for easy landing Charges in just minutes Realistic looks. Long flight times Ready to fly Motor type: 370 Dimensions: 23.5 in. L x 6.5 in. H x 6.25 in. W Main blades diameter: 19.5 inches Tail rotor diameter: 5.75 inches Colors may vary Includes: Radio control transmitter AC charger English manual Nimh rechargeable battery
This RC Mini Helicopter is fully assembled and comes with everything needed to fly except double AA batteries for the controller. Its good for people ages 8+. This mini RC Helicopter has good flight characteristics and is very durable.

Is this normal, no matter how far I trim it in the right direction it won’t stay steady. I have also noticed that the inside circuitry is loose and I don’t think it should be. What should I do return it or just leave it?
Maybe it broken.

So yeah, I’ve been browsing this website http://www.raidentech.com/mirche.html looking at micro RC Helicopters.
I’m thinking of getting one just for fun, at some point soon. I’m kind of a big kid at heart, when relaxing at home. I see some of these that only cost like $20 something bucks. I looked at videos of them on youtube and they seem to be very easy to control and fly very well. I see that I’ll have to choose carefully, as apparently there are a few that only have a 30 second flight time on a 5 or 10 minute charge.
Some have a 15 or 20 minute charge, and a 5 to 8 minute flight time. This is more of what I would be interested in.
So, some questions for those who have one: How long do these rechargeable batteries in this thing last? How many charges before a new battery pack for the helicopter has to be purchased?
Also…I see various 2 channel through 7 channel helicopters. All are not micro, however…and I like the micros.
Pardon me for being dumb, but what does each ‘channel’ mean? Why is 7 better than two? I see 2 and 3 channel micros.
Does each command/button from the keypad representing one channel that is responsible for each function…and each channel runs on a separate frequency for each function (so they don’t get mixed up?). Sorry, but I don’t know much about this techy stuff. 
Which one has the longest flight time of the micros?
If any micros are more sturdy (as far as crashes and such lol) than others…that would be helpful, too.
Hi Anonymous,
I want to warn you that the $20 micro helicopters have a 50% failure rate out of the box. I have worked with many of them myself, and the members of my RC club got about 30 of them. Fully half would spin uncontrollably.
All the ones I had flew for several minutes on a 15 minute charge. There is no new battery for the heli. These do not have any user-serviceable parts. It is put in by the factory and you throw it away when it stops working. But the failures were always with the mechanics or with the electronics. The batteries kept going after a hundred charges (on the few that worked well enough to keep using)
Channels refer to the control features supported between the transmitter and receiver. Not individual frequencies for each channel, but rather coded data sent on the one frequency the Transmitter uses. Two channel helis have the main throttle on one channel, so that the heli can go up and down, and the rudder, or yaw control, on the second channel so that you ca turn the heli. There is no provision for forward flight. You typically add a bit of weight to the nose so that the heli always drifts forward slowly the entire time it is in flight. A three channel heli adds elevator, or pitch, control. You can make the heli lean forward and back, so you can control forward and rearward flight. A four channel heli adds roll control, so you can fly left and right (like a crab).
The next step is typically a six channel heli, adding gyro control and collective pitch. These are the helis that can do ore aggressive stunts, like inverted flight.
Before you buy, read and ask question on the dedicated RC heli forums. You will learn a lot, and get better information.
