It fell into a bowl of water and now when I try to fly it the main propellers spin for a second but then stop. The blue lights still flash and the tail roter still spins. Anyone know what I did or can do?
Must be off, air dry, or in a warm place for a few days. then fully charged.you might have damaged the battery by getting it wet, if so the only choice is replace the battery.usually dried and charged is enough though.the lights require less power to run than the motor, thats why they continue to work even though the motor doesn't. Also make sure the battery is really full.watch for the lights on the charger (controller) to cycle,new batteries in the charger take about 15 min. to give a good charge.Good luck!

make sure the tail motor does not have any hair stuck in it take of the little propeller and clean it. next adjust the trim so when your taking off so helicopter will not spin any more and your good to go
I also have this kind of problem with my apache. The upper propeller must spin faster thatn the lower propeller if not the heli would just spin on its tail although maximum power is achieved. The solution is to check the connection of the gears and the axle of the upper propeller which is located at the bottom of the helicopter. remove first the battery pack to see clearly the connection. try to turn the upper propeller a few turns and see if the axle, gear and the metal connector is sliding. A fixed my heli buy putting a permanent glue on the axle, connector to the gear and whalla. it does not slide. Most problems of this model is the gear of the upper propeller, often times loosened specially during crushes. This will a lot help you as your heli would have power on the upper propeller for lift off. Happy flying.
Spinning is caused by one of the main propellers rotating faster than the other. If both propellers are secured tightly to their drive shafts, the spin control knob on the remote control can be used to stop the spin. However, if one prop is slipping with respect to the other, the spin control knob will not fix the problem.
I've found that the set screws holding the propellers to the drive shafts tend to loosen after a while. If one prop is a bit loose and the other is tight, the relative slippage will cause the helicopter to spin.
To check, turn off helicopter power and manually rotate each propeller separately, watching the nylon gears in the body. If the propeller is moving and its drive shaft gear isn't, the propeller is slipping because its set screws are not applying enough pressure on the propeller's drive shaft.
Carefully tighten the set screw and the problem should be fixed. DON'T OVERTIGHTEN, or the plastic threads for the set screw will be stripped and the propeller assembly will be ruined.
make sure there is no debris such as hair thread or string caught in the back rotor. this will cause it to lock up. Remove it and try fiddling with the trimmer button to help it stop spinning the helicopter
Make sure the blades and rotors are free of debris. I had the same problem then noticed hair had gotten wrapped around the blades. Once you remove the hair or thread or string or whatever it should fly fine
