What should I do to stop the propellers from falling off the rods? The rotation causes them to come right off.

A good idea is first to make sure the propeller nuts are tight before using the boat as a precaution. Then a lot of rc guys use a drop of Loc-tite on the propeller nut. Instead of Loc-tite a drop of super glue will also insure that the propeller nuts stay good and tight.

I had the same problem. What I did was unscrew the motor from the base and and use compressed air to clean the motor. Sometimes a piece of lead would get stuck inside the motor mechanism.

Same problem here. Sorry to say we've had no luck getting the wheel(s) to stay on. Keep reattaching, but still no luck.

Are you sure your winding it enough? Try putting it on a glass surface, after you wind it by hand, and tighten it a bit more. Also after lifting it make very pronounced/bigger circles with your hand to keep the gyro going. You might think it's not working properly, but keep trying you'll get the hang of it.

If by "intermittent power surges" are you referring to the motors seeming to go on/off/on/off/ etc while held at full throttle?? If so, I noticed the same thing on mine. However, it was on a day when the water was not smooth but a bit choppy. Remember in the instructions it stated propellers will not run unless in water?? Well part of the electrical connection system is a wire to each of the propeller axles (inside the boat); when both propellers are in the water there is a connection; if one or the other comes out of the water - connect ion is broken!! The propeller(s) bouncing in and out of the water would cause this. One solution would be to disconnect the two wires and splice them together; CAUTION: this would allow the propellers to turn while not in the water and damage to the propellers (or a person touching them) could result.

I have 3 of these and I can say that on take off the blades never spin exactly the same. Try a windless day and give yourself plenty of room then give it enough to get 8 foot in the air and you will find with some practice you will gain control. It is not something that happens in the first 3 or 4 tries. My hope is you have not given it enough power to really get in the air.

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.

Hold it upside down shake it, to let debris fall out, blow all over it with compressed air, make sure the batteries are good. That's about all I would know to try

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.

Do you have the correct propeller on the motor? If not, it thr motor acts as if it's working in reverse.

If it just keeps spinning, I would pull the rods apart, drag the screw towards the open end, and brace it with your pinky. That way you can get it to screw down some. Put the two rods back together. You can also pull on the screw while you turn it, to brace the square backing.

This was the fix for me. The top rotor came right off with no effort. I put it on and tightened the two phillips screws on top rotor to the shaft. It flew right away! Thanks for posting!

Tack them on to your oars them selves above the locks. When the oar slides down to the lock it will stop. it worked for me.

You just have to be gentle with it. I think I had mine get stuck a bit. Make sure it's closing the right way. Might be your best bet is to squeeze both ends of one side where it rotates. Just be careful not to break it. :)

My only suggestion would be to contact Syma. I have 2 of these helicopters and never had this problem.

Whoa... this is a huge problem! I bought these propellers and installed them, they work great! However, one crash later, I find that one of my aluminum posts has stripped and can no longer hold the screw, therefore I can't use these props AT ALL! We need to be able to purchase spare aluminum posts AND screws. Can you post specifications on the screws and posts so that we can find them at our local hardware stores when these things break, please?

Hasn't happened to me. I always check to see if have position and altitude hold working as soon I start the flight. Worse thing was having one of the prop capnuts come loose and the propeller coming off at about 150 feet in the air. That possibility has been lessened on the new version with reverse threads on the clockwise props. Still a good idea to check tightness before each flight.
