On dual cross country flight from charleston executive (jzi) to savannah (sav). Student was flying aircraft, navigating by radar vectors and pilotage, and communicating with sav (ATC) approach. I was instructing and observing. About 10-15 NM northeast of sav airport observed helicopter slightly above about 10 O'clock position from our aircraft, heading toward us directly. Unknown how close helicopter was horizontally. I took controls, pushed our aircraft down and was about 2400' when level again. Helicopter had passed overhead of us. Contacted approach and asked if they had called the traffic. Reply was that helicopter was level 3000' and we were supposed to be at 2500'. Informed ATC we were level 2700' and reply was that 'VFR altitudes were 500' above hard altitude'. This is only 50 above 3000', not below. Prior to this, we were in communication with beaufort approach (MCAS beaufort, sc), receiving stage 3. We checked in with beaufort at 2700' and were handed off to savannah at this altitude. From now on, I will instruct students to check in with approach during handoffs by saying their cruising altitude. This aircraft does not have mode C as yet.

Title: CLOSE PROX GA SMA ON DUAL CROSS COUNTRY AND HELICOPTER.
Narrative: ON DUAL CROSS COUNTRY FLT FROM CHARLESTON EXECUTIVE (JZI) TO SAVANNAH (SAV). STUDENT WAS FLYING ACFT, NAVIGATING BY RADAR VECTORS AND PILOTAGE, AND COMMUNICATING WITH SAV (ATC) APCH. I WAS INSTRUCTING AND OBSERVING. ABOUT 10-15 NM NE OF SAV ARPT OBSERVED HELI SLIGHTLY ABOVE ABOUT 10 O'CLOCK POSITION FROM OUR ACFT, HDG TOWARD US DIRECTLY. UNKNOWN HOW CLOSE HELI WAS HORIZONTALLY. I TOOK CONTROLS, PUSHED OUR ACFT DOWN AND WAS ABOUT 2400' WHEN LEVEL AGAIN. HELI HAD PASSED OVERHEAD OF US. CONTACTED APCH AND ASKED IF THEY HAD CALLED THE TFC. REPLY WAS THAT HELI WAS LEVEL 3000' AND WE WERE SUPPOSED TO BE AT 2500'. INFORMED ATC WE WERE LEVEL 2700' AND REPLY WAS THAT 'VFR ALTS WERE 500' ABOVE HARD ALT'. THIS IS ONLY 50 ABOVE 3000', NOT BELOW. PRIOR TO THIS, WE WERE IN COM WITH BEAUFORT APCH (MCAS BEAUFORT, SC), RECEIVING STAGE 3. WE CHECKED IN WITH BEAUFORT AT 2700' AND WERE HANDED OFF TO SAVANNAH AT THIS ALT. FROM NOW ON, I WILL INSTRUCT STUDENTS TO CHECK IN WITH APCH DURING HANDOFFS BY SAYING THEIR CRUISING ALT. THIS ACFT DOES NOT HAVE MODE C AS YET.
