Realistic review on these batteries for the V911
on March 1, 2013
First off, I want to say that I am very new to the world of RC helicopters (about a week). I did a lot of research into what I wanted to buy and chose this pack because of the many reviews. The ONLY reason I'm writing a review on a product like, "batteries," is because I feel some of the past reviews were a little misleading.
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!!
