I have a ZDZ40 RV with a 20x10 prop installed in a Hanger 9 27% Extra 260. I bought the plane/engine combo used. My question is, can I go to a 21 or 22 x8 prop? The manual only mentions props with a 10 pitch. Thanks

For the Hanger 9 260/ ZDZ 40 combination, the Mejzlyk 20X10 or 21X8 works the best by far. The NX will cost you RPM & power. Iknow, I tried it. I have ran over 30 gallons through my ZDZ 40 & tried several props with it. The engine likes the Mez. the best.
That said, Mike has just released a new line of props that are probably going to turn out to be the best allaround props for the ZDZ engines. A little pricey, but sometimes you do get what you pay for. I picked up one for my ZDZ 60, waiting on weather to try it out.
