WHICH HARTZELL PROPELLER MODEL?
Van's is showing both a 72" and 74" C/S prop for the RV- 14 & 14A for the 390Hp. What are the pros & cons of each option. They are both priced the same?

RE: Which Hartzell propeller model?
Glen,
I called Hartzell a few weeks ago with the same question. They had me contact Vans. Essentially, vans stated that the 72" is for both the taildragger and the tri-gear aircraft. The 74" prop is not recommended for the taildragger RV-14. For what it's worth, I ordered the 72" prop. I hope this helps! |
I had heard that before but surprised to see both listed on Van?s site for the taildragger. I guess they?re concerned about prop strikes??
|
When only considering an RV14-A (which can use either it seems), any thoughts on pros and cons on choosing one over the other?

FWIW, when I spoke to Mike Seager back in September, he agreed that the 74" Hartzell is the best-performing prop for the -14A. |
Why not put in on the 14 then? Is 1" less ground clearance really going to be a factor?

This topic has been covered in the past here on V A. Basically, prop length was reduce for the 14 to satisfy the drop test ground clearance requirements, I believe.
I learned this after I received my 72? prop (14) and was a little pissed. I would have preferred the 74?. I asked Hartzell if I could exchanged my unopened 72? prop and they said once shipped it is considered used. I advise, if you are a good pilot and feel you will not crash land or over rotate by an insane amount, go with the 74?. If you are a below average, have a tendency to lose control, wear a watch over 1 lb, and get lost on cross country flights.....go with the 72?. R |

Went with the...
72? on my RV-14. As strongly recommended by Vans. I have no way to know what difference another inch of radius would make, but I am completely happy with how it performs. 101 hours now....
