I replaced all of the motors on mine and props spin but quadcopter won't lift off the ground. Does anyone know why this is happening?

Make sure the right props are on the correct motors. If you turn on the propellers and you feel air blowing up, switch the left with the right and left with the right. The motors are counter rotating.

Try pushing the steering stick all the way to the left or right right at take off. It should correct the spin shortly after take off. More than likely, you may have 'unbalanced' one of the sides of the helicopter and it tends to spin that way at lift off. I had the same problem with mine, so I just start with the stick pushed all the way to the right every time now, and it works fine. You may also have to crank the slip stream in that direction as well. Good luck.

I love these things. Fly every day I can. I have found that drift, other than being caused by the wind, is a function of many things. First make sure you set the gyros on a level surface. If still drifting check all props for damage and replace if necessary. I have also found that by placing the copter on a balance table that uneven weight can cause the copter to drift. These are small copters and so are very easy to get to drift. Even replacing the motors and not balancing the craft can cause drift. You may also want to check for cracks in the body of the copter, I had to replace the body on one of mine. The crack opened up the arm enough to misdirect the thrust of the propeller??

Well did you remove the motors already? The props and gears are held on with a prop shaft and circlip. If you look on the top of the prop there is a tiny c shaped clip that holds the prop onto the prop shaft. Just push this off using your fingernails. They can be difficult, make sure you don't lose the clip either cause if you don't have spares your screwed and will have to order props (they come with clips). Once the clip is off you can pull the prop right off and the shaft will slide out the bottom. Then the gear comes off as well. Also make sure you take the cog off the motor as well you will need to transfer this to the new cross with your motors. The motors come off easy too. On the bottom you unclip the board (just a tiny plastic clip you can unplug with your fingernails), then it's three bolts on the top of the motor and two on the bottom. Make sure you don't mix the top and bottom screws cause they are different lengths. Then you just pull it out, turn it sideways to get it out. Then reassemble using the reverse procedure. Good luck.

simple. Your power is weak. Change the batteries with new good batteries. A friend of mine had a similar problem and once we changed to new good batteries it flew flawlessly. Smooth copter handles easy.

I bought this for my husband also and his didn't work either. The lights come on but the motor doesn't and none of the propellers spin. We contacted the company and they suggested that we try a new battery first so I had them send us a new battery, but it still has the same problem so I am going to ask for a refund !

Before you go to that much trouble , Try A different Prop , I did that on my P-51 ,Wow What A difference ,I also have the same model as you & have not flown it as of yet , Try U Tube for advice , on Eng Change I really don't know . Dennis

Ours worked great until we crashed it way too many times. After that it would get more than about 6 inches off the ground. So if you have crashed it a bunch, that might be the reason why

The bottom rotor maybe slipping, by putting a finger against the cog and gently apply rotation to the bottom rotors if they turn try this : hold the large upper cog and push the bottom rotors (connection assembly firmly down the main shaft - it should become more snug (try the rotation test above) on the shaft and hopefully lift is restored.I think this is a deliberate design to save potential damage or harm from the bottom rotors suddenly stopping on collision, ie a bit of slip on the shaft

it sounds like you need to push the fly/run button on the controller (lower right side). If you have pushed that button to change from run to fly, you may have a defective controller. This is a fantastic RC vehicle, I really hope this works for you and you enjoy it as much as I have.

Jerry,My only suggestion would be that if there is a pin missing, that is a factory error and you should have DJI or whatever store you bought it from replace the whole copter. Can you send me a picture of what you're talking about and I'll compare it to mine and see what I can come up with? I'm usually pretty good at figuring these things out.

With all Quadcopters the motors on opposite sides are supposed to spin backwards. What is normal is Right Front - spins Clockwise, Left Front - spins Counter Clockwise, Left Rear - spins Clockwise and Right Rear - spins Counter Clockwise. This configuration counteracts the effect of torque caused by the spinning blades. If they all spun in the same direction the copter would spin uncontrollably in the opposite direction. Just check to see if there is a bent motor shaft or if the props are rubbing on the chassis or something like that. It's not likely that there is anything else wrong. Replacement parts are always available from Heli-Max.

Ours did the same thing. Not sure how to correCT the problem. We bought this one because of the high number of positive reviews, as a trainer before purchasing the more expensive quad copter with camera. We kept this one for parts incase we buy another one, but pretty disappointed in this copter. Good luck, hubby did say there were some you tube videos on correcting the problem, but he has lost patience with it.

I have two suggestions for you. 1. Remove the plastic rotor. Make sure there isn't any hair wrapped around the post. It's amazing what these things can pick up when flying! 2. Purchase a new rotor because yours might be bent, keeping it from rotating. This happened to us before. You couldn't see the bend but when we replaced it, voila! If you've had this helicopter for awhile, it's possible that it's on its last leg. We have had these for several years and one is finally not turning the back rotor and it can't be fixed. We've gotten our money's worth out of it. However, if it's brand new, return it. Hope this helps!

make sure all controls are at neutral. swatch plate is level to both heli center lines. check tail rotor plug in at front of heli, if it still goes into a spin and the tail rotor is barely turning, it most likely needs a new tail motor.

You must unscrew the circuit board and remove the motor. It's a tight fit but doable you'll need to remove the propellers first of course. Keep in mind the pitch of the propellers. If you don't put them back the same it won't take off.

it is quite possible it is defective(it happens) if you 1 -turn on transmitter FIRST then set heli on a FLAT surface. turn on heli and wait about 3 sec. the built in gyro will engage . NOT doing this will cause all sorts of problems. check the balance everything should be factory balanced.also look at r/c flight school.com lots of info there.GOOD LUCK.
