I'm impressed..... I think..... I think you have big kahunas....I'm not familiar with the breaking point of those airplanes but I think the tails are comming off of the Turboprop Lancs. Dont take this as ragging on you... I'm just concerned....

Still in research mode....

Brian, shows how little you know about the Lancairs. First, the Legacy "RG" was *designed* for the IO-550, yep, from the ground up. And it's the only approved engine combination for it. Second, they race them all day long at Reno with over 600HP in the TSIO-550 configuration, current speed is over 350mph.

Just because I'm building an "FG" and not the "RG", I'm building it on the carbon (read as RG) kit, again the kit that was designed for the IO-550. (As a note the FG in eglass is only designed for the IO-360 motor)

As for the couple of IV accidents in the last few months. Not sure where you got your information, but I know of *NO* accident that was caused by a departure of a "tail" while in flight. Both of the recent accidents were caused by continued flight into IMC or ICING. If you read the accident reports, both were flights that were in real nasty weather and most likely flights that *should not have been undertaken*.

I'm certainly not gonna put my butt in an airplane that I don't have complete confidence in, and I'm not about to do something that hasn't been reviewed and previously approved by the FAA.

But alas, I suppose this is part of the "plastic" vs. "metal" bashing that goes on. I'm not going to get into the merits of one design vs. the other, that has been hashed out numerous times. Thanks for your concern, however, based upon the over 200 currently flying carbon legacy's with IO-550's and the fact that the airplane was specifically designed for that engine, I don't believe your concern is necessary. If I were doing something like taking an RV8 and putting an IO-540 on it, perhaps that would be grounds for concern, but because of the design, this is more like taking an RV7 and putting an IO-360 on it. Both were designed for each other.

Hey...the word is cojones! Kahuna is a Super-8 driver. :-)

Brian,

The Lancair Legacy was built around the IO-550 as I understand it.

I used to say that the fastest/best 4 place kit was from Lancair and the fastest/best 2 place was from Glasair. Glasair had a few stumbles and Lancair did not get it just right with the Tigress.

But the Legacy ... WOW!!! Tough on that Glasair III. Is what the Tigress concept must have led to and ....

Leader or the Pack at Reno. Daryll G. just "blows" everyone away with his supercharged (I think) IO-550 powered Legacy. If you gegt a chance, take a look at one of the installations ... nice!

Of course I think that RV's are the best "value". :-)

Wish **I** had a Legacy with an IO-550 :-)

Daryll, runs a TSIO-550 with dual turbochargers, and intercoolers, it's obviously not a stock engine as it makes around 600HP, I've heard they are going to bump it up to 700+ for next year. He turned 385mph in practice, and won the gold race at 365. I might be wrong, but I heard that MP was about 70" at 5000' at Reno is what they were running with water injection.

here is his engine


And here is his airplane


Both he and Lynn Farnsworth


have the ability to add "water injection" in a tank that fits in the right seat. They can then pull that out, and the airplane is back to a daily flyer. Lynn also runs this same TSIO combination.

Interestingly enough, the stock Legacy's ran about 290mph in a stock IO-550, altho they turn up the prop to turn about 2900-3000 instead of 2700...

Excellent combination of speed and HP... if I do say so

Lets not start airplane bashing here. I think all of these designs are much safer than the Wittman Tailwind I'm working on right now. Glasair is a inheriently more stout design, but the Lancair is slicker. The RV is cheaper than both of them, and the super-8 is a pretty decent setup, even without the factory support.

How did we get from Innodyn to this?
Any way lets not get our cojones in a bunch. Glassair , Lancair who cares
they are made of glue and string ; aadamson, nice pictures, that engine
cost more than my whole plane, impressive I guess. G

[aadamson]

George, that engine, most likely cost more than my whole airplane too!! But for us speed freaks, it is *cool*

[osxuser]

For my money, the big-bore lancairs and glasairs are just YANKing the airplane through the slipstream a lot faster than it really wants to go. I think the sweet spot for most of our airplanes lands around the Angle Valve IO-360 Lycoming, maybe up to the IO-390. But after that the speed gains per HP isn't all that impressive. 600+HP TSIO-550's don't get my blood going like a 2400HR SMOH IO-360, but I guess I'm just a bit on the wierd side .
