I believe fibercraft is involved with them for Lancair installs? And now on MT props too? Unfortunately too expensive for the stage it's in IMHO. If there were a bunch in the field tested and working great then maybe yes. Just too much to pay full price to line up as a test pilot. TKS, although messy is awesome. No run back problems. I never had a problem finding fluid before out or too low. But it's best in wings made for it, where the airfoil isn't changed.
Does RDD plan to buy and convert some Lancairs, or wait for a customer to buy one and bring it to them? Have you heard a timeline for flying prototype?
I've also noticed most of the cheaper IV-P are pre quick build and many have low hrs. So probably many not built as well since weren't using the factory jobs and hard on the engine not flying much or at all. Since the upgrade seems to pretty much trash all the parts that would be a problem in those birds it might get them off the market. I think the cheap depressed market prices are getting some lower budget low time pilots into a plane they shouldn't possibly be flying. Some pilots too cheap to pay for needed transition training. Look forward to seeing one flying. I agree the Villanger is expensive, but the concept is very similar to what I currently have, and it works beautifully. The nice thing about the Villanger is that it doesn't require nearly as much amp draw as the system I use, thus not requiring a backup alternator to run it. I'm pretty sure they have one, maybe two they are converting to sell, but otherwise that would be it. As far as timeline to have one flying. I don't know, I'll be out there tomorrow and will find out more then. I will say that all of the tooling that I saw last year for the conversion was quite impressive.

Username Protected wrote: I wish RDD well but I think trying to make the IV-P into airplane than anyone can fly is a noble but futile proposition. It's expensive and doesn't really perform any better than the existing IV that actually exists yet it costs 3 times as much. There might be a market for a few of these but RDD has had a lot of trouble selling their $500-600K refurbished IV Extras; the market's reaction doesn't bode well for $750K LX-7s. That may be true, but the little bit I've been around at air shows and other people I have talked with have shown tremendous interest. Why? Same reason I mentioned earlier. It's basically a poor man's Evo. Same/better performance at half the price. The Extra I'm sure is a completely different market. The Evo has a lot of interest, but Lancair cannot get out of it's own way to sell more of them, thus I could see a lot of interested people wanting something like an Evo go for the LX-7.

Gerry are you happy with yours? what changes would you do if you could wave a magic wand?

If I had a change to make it would be to have the Villanger prop, some way to close in the landing gear to reduce that drag and overhaul my engine so I could run at it's typical ITT. I'm pretty certain with all of those changes I'd be close to 330 ktas.

Username Protected wrote: I'm unfamiliar with the PT6-140AG. Web research this morning says the -140 is the latest and most powerful of the "small" PT6, with a single stage power turbine vs. the two-stage power turbine in "medium" engines like your -42. They improved the compressor with more CFD-designed airfoils and a blisk for one of the axial compressor stages. The torque limit (gearbox) is 867 hp. but thermodynamically it's a 1075 hp. motor. Its only applications to date have been the current Caravan, upgrades to older Caravans and ag planes. Blackhawk offers both -42 and -140 Caravan upgrades but not for much longer, I would think, as the -140 upgrade is more powerful and cheaper, requiring little or no mods to cowling and engine mount. The -140 also is designed for lower operating costs, 5% better SFC than "comparable" engines (whatever that means) and much higher cycle limits so even the ag and skydiver markets doing short flights won't cycle out before timing out. Besides the lower lifecycle costs, the pitch for ag operators is better hot/high performance. The -140 will of course lose power with altitude but as a percentage of the 1075 hp. thermodynamic rating, not the 867 hp. gearbox limit. I should think it would have more power available than a -42 at any altitude. And of course it is a more modern engine.
