From 02-04-2007, sintered rotors will be BRCA legal.
The following quote is direct from
http://www.brca.org:
"
9.7 The Rotor: Shaft diameter must be 3.175mm. Only one piece, two pole bonded Neodymium or Ferrite magnetic rotors are permitted until 01.04.07. From 02.04.07, sintered Neodymium or Ferrite rotors are also allowed. Magnet minimum length 23.0 mm, maximum 27.0 mm. Magnet minimum diameter 12.0mm, maximum 15.5mm."
Bring on the obscene amounts of power!
