I have only flown my v911 indoors and am waiting for winds to die down a bit before bringing this lil guy outside. I got my v911 less than a week ago and am really enjoying it thus far! The biggest downfall to the little chopper was the battery life from the stock batteries (130mah). As soon as I find my niche in piloting the chopper around the house, the battery would start to fade and I would have to re-establish my groove with the other battery.
I ordered this 5 pack of batteries at the same time as my v911, but it was being shipped from a different supplier and I didnt receive it until 3 days after I got the heli. I only say that because this gave me a decent amount of time of using the stock batteries and I can notice some very obvious differences between the stock battery and these bigger ones.
All 5 of my batteries worked as advertised, not a single dud in the pack. So that is nice.
*Fly longer! The 200 mah battery does increase the fly time by a solid couple of minutes (which feels like a long time when you are used the the short 5-7 minute flights from the stock battery).
*The connectors are the same and fits just like the stock ones do ("upgraded" v911 of course).
*These batteries would probably be much better suited in large, open, outdoor settings.
*Weight. I have read reviews that said the extra weight just makes the chopper "sluggish." To me, the added weight does much more than just making the chopper a little less responsive. I have seen VERY noticeable issues in the handling of the chopper with these larger batteries. The added weight creates a kind of pendulum effect with your turns and general movements causing your heli to swing back and forth in large arcs before finally leveling out. Even the simple act of rotating the chopper 180 degrees from a hover causes it to swing back and forth quite a bit before returning to the hover, and sometimes because of the ferocity of the swinging motion your heli will travel into directions you weren't quite intending it to go. The chopper has a hard time leveling out on it's own like it could with the stock batteries.
*With the stock battery, the v911 could turn on a dime. With the larger, heavier battery, turns are significantly wider than they once were. If you find yourself flying indoors more frequently than outdoors, this sway effect will definitely have you on your toes to keep from flying into stuff (walls, tvs, cats, yourself).
*These batteries are not well suited in smaller environments.
*Charging the batteries. Battery charge time IS longer than the stock battery. It isn't significantly longer, but they will take a little longer to charge (not the same time as others have claimed).
The whole point of this review is to shed some light on what I feel others have neglected. If you are a primarily indoor flight guy or flying in tighter quarters, like myself, your flying is going to be much more stressful than before with these heavier batteries. HOWEVER, take these outside with plenty of room then it doesn't matter if your chopper drifts into an arc 3x greater than before because you aren't going to break anything. I would not recommend these for smaller areas, but for larger, outdoor settings they should be perfectly fine.
All in all, not a bad product. But I would have opted for the smaller batteries due to my indoor flight preference if I knew the handling was going to be so drastically affected by the weight of these batteries. Oh well, at least I have a healthy supply of "outdoor batteries" now! I'll just have to order a set of smaller once for in the house.
Also, you will have to adjust your pitches/angles and stuff on the transmitter when you switch between batteries otherwise your heli will be all out of whack.
Hope this helps!!
Like Brian I am new to RC helicopters - the v911 is my first, I have had it about two months now - and I bought the 200mAh batteries pretty much straight away and all 5 worked fine (unlike one of the 130mAh batteries that came with the v911). I too have only flown it indoors so far so I cannot comment on outdoor performance (though there are plenty of videos on YouTube).
The extra flying time with these 200 mAh batteries really does make a BIG difference - I always pull a face when the surviving 130 mAh battery comes up in my charging rotation - and the slightly longer charging time is not a big deal.
Unlike the original (130 mAh) batteries, these 200 mAh batteries do not come loose on every little impact (which requires you to re-synch the controller with the hell). In fact I have only had them come loose a couple of times, both pretty hard impacts. The little white connector on both of those batteries now wiggles around a bit but both continue to work perfectly.
Regarding the effects of these batteries on the v911 in flight:
* Yes, the larger battery does add significant weight to this very light helicopter - the change in balance really requires re-trimming the controls, though it isn't really a big adjustment and if you switch to exclusively using the 200 mAh's you only need to do it once.
* I actually prefer the balance with the 200 mAh batteries, it feels more stable in hover and low speed maneuvering
* I can see how one might describe the v911 is "sluggish" with the larger, heavier 200 mAh batteries but the helicopter is still quick and agile yet it feels a bit more tame and to me, as a beginner, that is a good thing.
* I have noticed the pendulum effect / tendency to keep moving a little bit, particularly after moving forward / backward. This effect is also present with the smaller 130 mAh batteries, it's just not as noticeable. Another reviewer (Workin Grandma) suggested "a dab of play dough in the nose of the chopper body" as the solution, something I intend to try out when I get my hands on some playdough. It doesn't put me off flying indoors at all - the effect is not that bad and you need to maintain active control of the helicopter in an indoor setting anyway.
* The extra weight of the 200 mAh is not enough to significantly increase your chances of breaking anything except maybe the helicopter body. I've crashed my v911 many times in the last couple of months and the only damage so far is a few small dings in the body paintwork and a couple of notches on the rotor blades. No damage to the furniture yet, not even to the paper lamp shades.
* Finally you may have noticed that for the last minute or so of battery life, the helicopter wants to rotate. This effect is still present with the larger battery but with a longer flying time it does not detract as much from the fun.
In summary, I highly recommend the 200 mAh batteries and would buy them again in a heartbeat.
** NOTE: These particular batteries are for the newer v911 - see the small white connector at the tip. Be sure you get the correct version for your particular helicopter, as they are not compatible with the older version.
