Rock,

Michelin tubes seemed to fix that issue in IV-Ps I flew regularly. The Goodyear tubes were notoriously leaky.

Jeff, I stand corrected.

What is the difference between the IV-PT and the propjet? It’s a different name for the same aircraft. My guess is the term “Propjet” was borrowed from the Piper pre-Meridian PT6 conversion STC, and it just stuck. As far as the IV-PTs go, there was no official name differentiation between the Walte...

I think the MT is super-smooth, but it wears much faster than I think it should. I’ve flown several planes with MT props, and all of them wear with pitting, paint wrinkling, chipping, etc. I have also seen a number of MTs that had blade delamination. One small chip that goes through the outer fiber...

Hello all... Anyone have experience flying a IV with the Friedel tips? If so, any thoughts on performance? Cost? Etc? I'm partial to the aesthetics of the X-Pros but my understanding is that there are no plans for them to manufacture more of them "...for the foreseeable future." Bummer. T...

George,

How much time do you have on the engine?

Hi Ken. There’s a lot to cover here. Any thoughts on using peak TIT as the reference point for leaning a TSIO 550-E? This is SOP in a Cirrus with a TSIO 550-K. Well, I should clarify: the actual SOP is to use the computer generated cyan target for leaning; but leaning "manually" to lean of...

https://www.kitplanes.com/taming-the-lancair-iv/ I have some history with those wingtips. I flew an Epic LT equipped with them a number of years ago. The owner installed them hoping for additional speed and fuel capacity. The flight characteristics, much as mentioned about the IV-PT in the article,...

I want to make you all aware that there is interest from an underwriting firm to begin quoting the Lancair IV-PT (propjet) with specific modifications (STC) produced by York Zentner and his group. Many of you know York and his organization. There is potential for the piston Lancair IV and IV-P to b...

Darren,

If you have an airplane you’re curious about, let me know. I’ve flown about 85% of the fleet, and I’d be happy to give you background on any specific one you’re interested in.
