Narrative:
On landing; he got me off the runway with a full right rudder left aileron lockup. No damage; no mention on the frequency. We need more work! I think he would be ok on a zero crosswind session; but no longer sure. On several occasions in the last three sessions; I have had to save a landing with power and right rudder. Crosswinds were generally 220/8 with occasional gusts. This particular landing was that way - I got it straight and let go; showing him he was still flying the aircraft both with words and hand gestures. He immediately jammed full right rudder in; and when the nose darted to the right he tried to correct with full left elevator. All this happened in an instant; at which time I took the aircraft; straightened it out with power and appropriate controls; and got it airborne. At no time did any portion of the aircraft other than the wheels contact the ground or any runway lights.a post flight inspection indicated that no portion of the aircraft suffered any contact or undue force. Both tailwheel springs had jumped out of their loops; which is common with tailwheel shimmy or excessive rapid tailwheel movement.no mention of this incident appears to have made it to official channels - no comments were made on tower frequencies. It is possible that nobody saw it - it took only about ten seconds; start to finish.
