I would like to get my engine and prop ordered to lock in pricing and make sure I don't have any delays. I would like to go with a composite prop and have narrowed my choice down to the 3 blade MT, or the 3 blade Hartzell with the steel shank (instead of aluminum, and adds a little weight). I am going with the Lycoming Thunderbolt YIO-390-EXP119 w/Acc, with Dual Emags, normal compression. The MT is $15,700 and the Hartzell is $21,900. For those of you that have either of these i would like to understand:
-Price Difference: Why is Hartzell $6200 more?
-CG: I understand the RV14a tends to have an aft CG. Do you have any problems going with a 3 blade composite vs. heavier aluminum? If i intend to put on A/C would the weight of the A/C (compressor) make the potential CG problem better?
-Performance: Any difference between the MT or Hartzell?
-Choice: What led you to choose one over the other?
I do understand there is more value in doing the aluminum 2 blade from Hartzell, as they are under 10k and have very similar performance. I do understand some folks have a more difficult time removing/installing the cowling from a 3 blade prop. But for those of you who have put a composite prop on, I would love to get your advice. I have tried to review all posts associated with Prop choices, and could not find this info.
Thank you!
