Setback - pros and cons

[showmepro1200]

Tell me about impeler setback - is it worth it? Any pitfalls from having it done, say to a Solas Concord 13/17 repitched to 12/17 on a 1990 Superjet??

I'm running a 12/15 3mm cutback although I wish i had gone 13/153mm...and I enjoy it alot.

Thanks - I probably shouldn't even be second-guessing here, it is being done with the blessing of Dave at Impros (I'm probably one of only a handful of people that actually spoke with him yesterday) so I know it's being done right and will do me well.

Anyone else have the setback option on their props? Comments?

Thays hard to say without knowing engine setup ..but they know what they are doing so if thats whats they said then it sould be right.

if you move the prop closer to the stator you get better hookup
its always worth it
