Then I'll bend my head in shame
Never checked myself before, but several experienced guys claimed this, both for IFMAR and ROAR.
See previous discussion:

Quote from Chazz (X-Factory): "There's an IFMAR requirement that you have 6 cells, so at the Worlds everybody just put another solder tab on the 5th one."
Quote from SupahDave: "You have to run 6 Cells per ROAR rules."
Might this have been changed for 2008 then? In any case it's the rules now, so I apologize!
Has anyone heard anything as to IFMAR allowing LiPo?
Edit: More on ROAR rules:
It actually looks like the americans didn't read their rules properly. In the ROAR Rules 8.3.1.12 it says "Unless a lower number is specified in the class requirements, a
maximum of six NiMH NiCad and 2 Lithium type cells is permitted in any vehicle motor power pack used in ROAR-sanctioned competition."
ROAR rule book:

8.10.1.3 for 1:10 OR also specifies this: "Six cells maximum"
See 8.3.2 for LiPo rules:
-there are some "UN" criteria (transport safety regulations)
-ROAR testing & approval (drop, overcharge, short circuit)
-must be hardcased from ABS plastic or similar material
-case halves "sealed" with ROAR approval label (you are not allowed to open it)
-2 cells in series
-3,7 V pr. cell
Charging rules (ROAR):
-charger with LiPo program (of course)
-must have LiPo inside "LiPo Sack" (or similar) when charging (to mitigate fire)
-max 1C charge rate
Note! There's nothing to gain performance wise from charging LiPos at a higher rate than 1C!!! You ONLY save time, and it may be damaged!
To my surprise they may be damaged by being stored fully charged for more than a month. It's advised to store them 1/2 full...
The ROAR rules are VERY detailed and would be a very good place for EFRA to take their initial rules from!
This is the list of approved LiPo batteries:
