Mine glitches about 2 mins into each flight (stopwatch) - descends uncontrollably. If throttle is raised it slams the ceiling. Is mine defective?

If you can hover it fairly ok, after some time it will need more power cause the battery's start to go down a bit but it should never have a huge change in flying with out a control input. If it's hovering or flying slow and descends rapidly with out your command it's a problem most likely... Best of luck

I would try another battery.... I have read that batterys can be bad or go bad. Other wise you may have a bad transmitter

Yes definitely defective, I bought 4 of these none had the issue you describe. I would have loved it if they fall of the sky instead of getting stuck at giant trees ;-P

I believe you can fix that by adjusting the horizontal trim on the right stick, could be the left though...been a little while since I've flown it. Good luck.

My answer to this question was to return the plane, I have never bought such a low quality piece of you know what. The fact it even flies is amazing. Mine flew just good enough to get it to the crash site.

Make sure the flight controller is free of vibration, and the wires are secure because vibration can travel up them. If problem continues verify radio and receiver with a range check. Maybe back off the gains a little or place a ferrite ring on the inputs of the gyro. All fails chuck it get a Openpilot cc3d 10-15 bucks Ebay

Unplug and reset it. Put it on a level surfacenter and recalibrate it (left stick down and right, wiggle the right stick left and right) if this does not work, make sure the propellers are both good, and put on correctly. A goes with a, and b goes with b. Happy flying!

sounds like its not sinked with controller. turn controller off plug in the battery to copter then push in the left controller and hold(it should click) and turn on controller at same time and watch copter lights will change hold until shows steady light. and it should be good to go

We had the same thing happen. I think that when we were trying to figure how to fly, we pushed too hard on the remote and messed up the buttons, maybe even stripped them. We even had the middle dial changed to different directions, and still did the same thing.

I would say that it is defective. My grandson's chopper flies easily and he controls it very well.

I have never had this issue, make sure it is hooked up correctly in the front, have the riders lean back and make sure to take off fast enough to get the tube up on plane.

I don't know what to say about your problem,but I do know they have not responded to my question. My Co-axial flys backwards,and has since I bought it. It won't fly forward. Sorry I can't help. I just wonder if they got some bad ones.Buy one from the mfg. and it is over $100.00. Makes ya wonder don't it. Again sorry. cvbridges

I have not flown mine in a few months but if i remember right 10-15 min. And when it dies it cuts out qiuck with little warning and will drop like a rock! Still fun to fly and pretty rugged.

I was having this same issue. It seems like if I accelerate up slower then it doesn't cut out. I tested this by keeping it on my desk, while keeping it down with my hand, and accelerating quickly. It cut out. Then, I re-did the test, accelerating slowly, and it doesn't cut out.

Must be defective, or it sounds like its coming from the chute itself. Have you checked it for nicks? I have not had this problem.

It might be defective but it is tricky to fly. Make sure you adjust the trim while slowly throttling up.

I've never had that problem, we put a lot of miles on our co-pilot. Maybe it's a defect?

Had similar problem. Out of the box, the copter flew fine (apart from my novice controlling). From the second flight onward, it would not get any higher than a couple of inches off the floor. I trolled the forums to try and solve the issue. I purchased a replacement battery, struggled with the fiddley fitting of it and still not sorted. I've now ordered another copter off amazon 'cos my lad (and me) really want to have one of these working. As a last resort I've just applied a little WD40 (via the WD40 straw) to the cogs and the bottom of the shaft and Hey Presto, works a treat! Looks like me and the boy will be duelling now that i've ordered a second! Hope that this helps anyone with the same issue. Had similar problem.

Check the actual servo and see if it is fully functioning...see if it is sticking in an upright or downward position. I had this problem with a MJX F47 and it was the servo.
