Raising the question again -
Any reasons why not an MT prop on a standard IO-390 install on a 14 ?

From a mntc perspective, hard to get the lower cowl on/off with a 3 blade, plus no where to turn the prop where the blades aren't always trying to jab you in the leg or eye.
I don?t have a horse in this race, but recommend you do a value equation on the various prop options. No prop has proven better performace than the two blade Hartzell BA, and many props degrade performance. Considering the standard Hartzell prop is one of the lower cost options I?d need a lot of convincing on why I?d spend twice as much money on a prop that may or may not provide the same performance.
I?ve been trying to convince one RV-14A owner to dump his very expensive, high end composite CS prop for the Hartzell. He has never gotten anywhere close to Van?s performance numbers.

If I sacrifice a few knots in the cruise.... so be it.

I've had an MT on my RV-10 with an IO-540-C4B5 for ten years. I have one mag and one Lightspeed ignition. I live about 20 minutes from MT USA in Deland, FL. They've been great to work with over the years, including an overhaul I had done a couple of years ago. They've told me repeatedly that, even though the engine and prop are a certified combo, since I have a non certified electronic ignition, there is no warranty.Errrrrrr -
We have an MT on our RV7. Titan ECI IO-360 with dual P-Mags and MT were completely happy with that.
I am enquiring from a weight and balance point of view because I understand that 14's are coming out tail heavy.
The MT is an exceptionally smooth prop, accelerates and decelerates way better than the Hartzell - may not be as fast, but we are not concerned with the last 5 knots.
