Dave,
I am interested in purchasing a DZ 140. However, I can't find anyone who has run low pitched props on this engine. I want to stay with a 6 pitch (preferably), or an 8 pitch as max. You have replied that you have no experience using these low pitch props on the DZ. I know, I know, anything that keeps the engine in the low to mid 8000's. Problem is, I don't know what 6 - 8 pitch prop will do this. If I sent you a Pro Zinger 18x6 and 20x6, would you be willing to test these on a DZ and report your findings? I have seen several others on RCU wondering the same about low pitch props and the DZ, it might benefit you to have the information.
Thanks, Robert.
