After a crash there are a few things to check. First look at the two link that connect to the main blade grips. These will often pop off in a crash. They are easy to lose so the kit includes four extras. I found a tip on the Helifreak forum that works great. <Here> is the link to the thread. You just put a small amount of Goop on the ends of the forks on the head block. After doing this I have had the links pop loose from the blade grips but never both ends. So this was a great tip!

Second: Check the battery. Sometimes in a crash the battery will come out of the holder a little. This upsets the balance of the helicopter. The tabs on the sides of the battery need to touch the battery cage.

Third: Static tracking on the tail blades. Rotate one tail blade parallel to the tailboom and position your fingernail at the tip of the blade. Rotate the tail blade so the other side is now forward and parallel to the tailboom. If your fingernail aligns with the tip of the blade then the static tracking is good.

Fourth: check for up/down play in main shaft. Grab the rotor head and feel for any free play. Even if it is just a tiny amout it will be enough to effect the way the helicopter fly's. If you do have free play then remove the battery followed by the landing gear. Check the flat spot on the main shaft. If it is in alignment with the flat spot on the gear then you are ready to push the gear back in place. I have had times when the gear rotates and it takes too much force to rotate it back. I use a flat blade screwdriver under the main gear to leverage the main gear off of the main shaft. I then align the flat spots then push the gear back in place. As you can see in the picture below I place my fingers on the top of the head block and my thumbs near the hub of the main gear then push it in place.

What if the tail blows out during a maneuver?
This is usually because the tail blades have lost some of their pitch.Grab them and twist them equally. Make sure both have the same angle.
