A zero time/yellow tagged 12D40 with 6101A-12 blades! This came out of a cache of RCAF surplus props uncovered by Sun-Air Parts (
http://www.sunairparts.com/).
Ask for Dennis and tell him that Brandon sent you. Not cheap, but the real deal seldom is. I've been looking for a T-6 prop with A-quality -12 blades for some time.
The new 6101A blades made in the Czech Republic under license from Ham Standard are $13k a pair.
For those wanting to run in the experimental category I have a shorter prop (measures out to about a -17) that could also be cut down further for a racer.
