hi guys.
i have a problem with my cx 2 i just purchased it about a month ago. and now it seems like i only get a minute of flight before the battery dies... than it will only hover like 4 feet of the ground and when i push the rudder it just drops to the ground and then will pop back up to like about 4 feet.... it does this with both batteries. so i am just curious if it could be a problem with the batteries or the charger or maybe the 3in1 unit itself? thanks in advance.

I have the same thing going on with mine. Do you or have you been flying it alot?? I think it is the kind of batterys I am buying, because I get them from the .99 cent store. So I am going to try top of the line new one's and see what happens? Mine is only that old too but I have been flying it all the time not hard or crashing or anything like that. Have you talked to your LHS ? And what did they tell you? Are you taking the batterys down to where the flash when they are in the blade when it is flying? But ten bucks for a battery that only last twenty times is not very good.

yes i have been flying alot with the batteries. I havent talked to the LHS im going to call them tomorow and bring in my heli and batteries maybe they can test them on a volt meter or something...

You have permanently damaged the battery by over discharging it. toss the battery, or you will ruin the 3 and 1 control unit. i had the same problem with a 30 dollar battery. i was flying my cx2 to the point where it wouldn't take off. do not attempt to charge it again as it can cause a fire. get a new battery and have a stop watch set to 6 minutes of flight time.

He might be right as I just went to the store and got some good batteries and she fly's great and I get about 7 min out of a charge. That's where I have my timer set for on my radio. I know if you run any lipo down to far they are gone no coming back from that.

I've ruined more darned batteries by over-discharging them! For some reason I just never got a timer. So I finally remembered one day when I was in Target. $6 for a digital timer. It will pay for itself twice the first time I DON'T ruin a battery.
Too soon old, too late smart.

haha yeah i just went a picked up two new batteries from the hobby shop and charging them now. i guess all the hovering i did in my room wasn't really higher than 2 feet i couldn't really notice the voltage dropping.... just when i started taking it outside i was like wow only 1 minute this sucks haha. thanks for the timer suggestion i just went and bought a watch to use for a timer so this wont happen again. thanks again guys! happy flying.

Edit: oh and thanks soloboss for that great write up you did on cx2 setup on heliwiki that saved me alota trouble with the TBE seems to happen every crash lol.

Edit: new battery seems to fix the problem with the flight time! but everytime i spin the tail in a pirouette or maybe a half pirouette it seems to drop altitude to the ground now would that be a sign of motor wear or the blades not balanced correctly?

that is normal. one way when you will spin you will go higher, and the other way you will drop.

The second you notice a power drop when flying your CX2, land immediately!! If you continue to fly it after this point you will damage the Lipo for good! After about 10 minutes of flight time I land whether I notice a power drop or not. When I throttle up my CX2 with a fresh Lipo, that stick movement starts the 9 1/2 minute timer. Its a nice feature to have because it lets you know if you flight times are getting shorter.

hahah that makes sense! man i was thinking something was wrong but the blades spin different ways i guess i was just spinning the way the air pushes down the heli lol. thanks!
