WLtoys Large V912 4CH Single Blade RC Remote Control Helicopter With Gyro RTF

BE SURE TO READ THE UPDATE AT THE END OF THIS ORIGINAL REVIEW After gaining enough experience with the large "Hercules Unbreakable" that I could use up the battery without crashing, the time had come for me to take on a greater challenge. Having to constantly counter the unpredictable turbulence this helicopter generated in our small front room was very good training, so I felt certain that I was experienced enough to move outdoors. For those who don't know, the "Hercules Unbreakable" (and most all other coaxial helicopters) won't handle even a light breeze with the standard tail rotor, but by modifying the blades (I used cuttings from an old credit card glued to the bottom side of the blades that exactly doubled their surface area) it can handle winds up to about 5 mph with no problem. Well my modification worked absolutely great, only to discover that the transmitter binding with that helicopter would drop out at around 25 feet. Needless to say, that was a disappointment, but the Hercules had served its purpose and it was time for me to move up to something better. After watching several YouTube videos of people flying different types of these electric helicopters I decided on the V912. In being confident that I could master its 4 channel transmitter and speed through one careful step at a time, I ordered one and that's when the real disappointments started. I was like a little boy at Christmas time when the delivery was made, but instead of charging the battery and jumping right into a test flight I followed the advice of others, put batteries in the transmitter, let it bind with the helicopter, and checked it out to see right off that the swashplate was not level. Then I saw the reason why.... The jerk who was assembling that helicopter installed the right servo arm a notch high of center, then instead of correcting it, he/she screwed the adjustment all the way down in trying to compensate, slapped on an OK sticker and boxed it up. If not for those who took the time to offer advice, I would have tried to fly that helicopter and it would have crashed, but thanks to them I was able to return it undamaged for a full refund. (Note: The helicopter would have required disassembly to reposition the servo arm of which I was not going to attempt on a new one.) In thinking that the first one was just a matter of bad luck I ordered a second one to be disappointed again in discovering right off that its transmitter was defective. Naturally I didn't try to fly that one either and I got a refund, but my biggest mistake was in not selecting another one where free shipping was offered because I had to pay all the costs of shipping. In summary, I can't say whether these V912 helicopters are good or bad because after placing two orders I still haven't had the chance to fly one, but what I can say is, there is CLEARLY no quality control at all in the production of these things! More than that, the first one I received was DELIBERATELY packaged, knowing he/she had made a mistake in assembly that would render it unusable! That falls directly in line with people's dogs being killed by the additives those Chinese put in the dog food for the sole purpose of cheating on the protein content! I'm not going to say that you shouldn't buy one of these, but I am warning that if you do, order one that is backed by Amazon so that you can get a full refund. Don't make the mistake I did in ordering from an outside supplier who will not reimburse you the cost of shipping if (when) you get one that is defective.... For me ....I'm done! I really wanted one of these helicopters, but apparently it's not meant for me to have one. Good luck toward whatever you decide..... UPDATE 9/27/2014: Well in February I changed my mind, placed a third order, and I suppose that old saying "third time is a charm" is right. I had to change my rating to five stars because I have been flying this #3 helicopter for a little over seven months now with no problems, and it's still flying great on the original battery. (I'll have to replace the battery before too long now because it is finally showing signs of age, but I certainly can't gripe after "I can't even guess" how many times it has been recharged.) I thought I was ready for a four channel helicopter, but believe me, going from a three channel coaxial to this one was an all new learning experience. It survived multiple minor crashes with only a few scratches though, until I finally reached the point where I could handle it properly. I'm not going to ramble about how much fun this V912 turned out to be after I got good enough with it to take it outside. I'll just say that I'm amazed that it has lasted for over seven months, so far, when I didn't think it would last very long at all when I ordered it. Now I don't fly it every day, nor do I fly it when the temperature outside is above about 75 degrees because both the battery and motors produce heat that can literally burn it up in hot weather. Early morning is the best time to fly anyway because that is the most calm part of the day, and flying in strong winds just isn't much fun, at least it's not for me. I also allow about an hour for the battery to completely cool before recharging, which might be the reason I haven't already had to replace it. I treat this V912 with care, store it in it's original box, and it has served me better than I would have ever dreamed it would. I can't verify they are all like this one, but if they are they're well worth the price. Good Luck!

I was very pleased to receive the Heli before the delivery date listed . I was pleased with the quality of it . It's not a cheap toy . T he Heli looks to be well built . It has taken a few "controlled" crashes and has come through with flying colors . I've purchased extra parts to keep it in the air . At this point I know there will be some damage to the Heli with the way I have been flying it . So far I've had to replace the main motor . This is one of the things that seems to be replaced often . That is the only flaw I've found with the Heli. If there was a way to prevent the motor having to be replaced often it would be a perfect product. Amazon has come through with quality and quick delivery's . I'll buy from again . Go Amazon ! (( UPDATE)) After using the V912 I have some information to pass on . First is the transmitter problem . I don't have an explanation or answer for loss of power . I do however have answers to flight problems . It's imperative that your swash plate be level . Second try to fly the heli right out of the box . (Make sure swash plate is level) If it fly's to one direction every flight adjust the trims . If you find you cannot correct with trim then look at the arms that connect to the servo and the swash plate . Disconnect the arms (or connecting arm) that is on the opposite side of the Heli and lower it by turning it so it has less throw . This should correct the direction of flight. If you cannot correct that adjustment then you need to correct the trim itself . The way to adjust a trim button you disconnect the arm or both arms and do the following . The trims should be centered . To center trims press each trim to one direction . Listen to the number of beeps . Go all the way to the end until you cannot go any further . When you reach the end ,reverse the direction and stop. Then go in the opposite direction counting the number of beeps . When you reach the other end note how many beeps there are and divide that number by 2 . Now move trim button half the number and that will make trim exactly in the center . Do this with all trim buttons and then make adjustments from there . ( Note before testing make sure the swash plate is level). You should have plenty of adjustment . The next problem is motors that burn out. I have found that the Wil-Toy V 913 motors can be used in stead of the V912 ones . A slight modification and the motor will work. The gear on the V 913 motor is slightly longer than the V912 . By adding a small shim or two small washers on the two screws that hold the motor will compensate the difference . The V913 motor has more windings and stronger magnets than the V912. Go on U-Tube and look for motor modifications . Its there . The V913 motor has more power and I would guess make the motor last longer . I can tell you it has more lift . All these small motors have a small life spans so resign your self that they will need to be replaced . These suggestion are from my own experience and if you make these changes you are on your own . I don't guarantee any of these results and these are my observations. Good luck . Amendment : As others have stated there are a few things that need addressing . 1 The manual could be written a lot better . The type is so small you need a magnifier to read it. 2 The battery needs to last longer . ( I read by upping mAh value you can hurt rather than improve its performance. ) 3 lastly as stated the motors could preform a lot longer .

From the first day we received this thing we have been charging it and up until today .. nothing. . Never worked.. tried to contact the seller still no success. . Simply a waste of my money..

Looks like a good helicopter but it came with a broken servo.

Déçu de la durabilité médiocre de moteur

Was broke would not charge battery was dead would not recommend

Severe pull to right. Just crashes as you cant steer it.
