I bought an A-10 air hog and it does not fly correctly, is there a solution?

IT SOUNDS TO ME THAT WHEN IT CRASHED YOU MAY HAVE DAMAGED THE FLYBAR OR MISSALIGNED THE PADDLES THIS WILL CAUSE IT TO VIBRATE AND MAKE IT UNSTABLE
HOPE THIS HELPS

it could be that you just need to use the adjustment nob it is next to the right joy stick u can turn it to make the heli fly straight. or one of your blades is not working like it should.

fix the trim while flying it it works better

If you trimmed your heli but it still can't work, try using the direction knob to trim it instead. When it goes clockwise push th knob leftwards and hold, and vise versa for anti-clockwise. Or, push and release repeatedly in the direction mentioned till it flies straight. Tested on around 6 air hogs helis and works each time. If you still can't trim you might try it after turning it off or contact the service centre.

wipe your **** and smell the paper

I have an Air Hogs havoc cyclone stunt plane. I am not sure if your plane has this, but on my plane's remote there left and right steering trim buttons. Play around with these until your plane flies correctly.

The top rotar blades are not turning but are slipping every now and then.

You only need one frequency to be able to fly it. So it's working fine.
