YS DZ160s... OS-160 EFI

[David Lockhart]

And...as long as the 2C contingent is speaking up........

The modified 3 blade that I run has been tried on a number of different
engines - OS140 EFI, OS 140 RX, OS 160 EFI (Jason's, along with some other
props as he mentioned), Webra 145/160, and YS140DZ.  The 3 blade runs quite
nicely on the 2Cs w/ 15-20% nitro.  The 140DZ won't handle the prop even
with 30% nitro.

Regards,

Dave Lockhart (no engine sponsorship here!!)

PS - I've seen several 160 FX and EFIs run well - but none would keep up
with "THE ONE" Jason has - that particular sample must be the one were all
the tolerances are just perfect.
