I do keep my front strut full but still has plenty of cushion. I get outstanding performance with this prop. I just posted an ECI cold air induction system installation on LML a few months age. I'm getting a consistent 216 knots cruise at 4K ~ 5K feet with this prop. This plane was raced at Reno with this prop. You will need to get an extension, about 2 1/2" to 3 " I believe. But it's much less money then the F7068-2 prop, about 12K. You can get a used Mooney prop for around 2K, have it cut and overhauled and a prop extension. You can use the Lancair spinner and backplate from Kitparts, or an ACS spinner kit but it requires modifications. I have a brand new F7068-2 prop in the box I haven't tried yet. I don't think it will out perform the one on there now. Randy Stuart LNC-2
