Indeed!

And 1.1mph is 2956.79 furlongs per fortnight.

I’ve done it, not with Lasar’s but with my factory wingtips and have done it twice now with 2 different antenna’s. After exhaustive speed runs, by my excel calculations the speed difference came out 3.14159 kts. at 9500’ +/- 3

Touche'!

Who here remembers that one time I posted one million digits of pi, but then everyone got mad at me since it ended up freezing up people's downloads?  I learned a lesson that day.  Friends don't use too many significant digits with friends.

You guys have nailed it!

I don't know what you are talking about.  We are being absolutely 100.3% serious.

Erik,

I can't believe there is single MSer around at the time that doesn't forget that!

But FTR, I surely didn't have an issue with it, I like significant digits as much as any nerd  How about 2 million on your next b-day!

Thanks for remembering - 2 million on my next birthday?  You got it!  :-)

Any chance someone knows what it would take to get an order through?  Do we need a minimum of 10 people to sign up?  I'm pretty sure I'd be up for this.  -K

Is the Aveo Wingtip not for the short bodies? I can see if Damien at Aveo may want to use a customer for certification for a short body. If it already is good to go then you can buy them.

Didn't think it covered the J. Would love to hear if it does. -K

I saw some very large dihedral winglets custom made for a Lancair IV-P, flight testing show pretty amazing gains in cruise speed, climb rate and also contributed to a reduction in stall speeds.  https://www.kitplanes.com/taming-the-lancair-iv/  

Makes me wonder if going BIG (presuming enough directional tail surface) might have similarly positive effects on Mooney's?

[aviatoreb]

This go big vertical wings reminds me of some other era - but I can't quite remember when....

Nothing for the short bodies at the moment, and only for the later model J's/K's. 

In the past when we've talked with Aveo, they seem to be focused on building parts for US military drones.

Be still, my beating heart!  Man, such great childhood memories

If a winglet helps in cruise, it says the airplane doesn't have enough wing ... or has gained too much weight.

I’ll bet this winglet helps with cruising  on a Saturday night !!

Welcome aboard RedWolf...

We have a Mooney Rocket, now Lancair IVPT owner around here...

We could ask him...

Best regards,

I read that article through - sign me up!

The lancair gained 20 knots in cruise (out of what - 300?) and lowered its stall speed by 10knots.  And improved stall characteristics.  Seems like a fantastic deal for them.

Huh - I would be happy with 12 knots faster cruise since I am only 2/3 the speed.  And 5 knots slower stall would be impressive.

My first car.  Note horizontal fins. I’m sure they developed some lift

1959.   That is your specific auto?  A beauty!!

It looked the same, but this is a photo from the internet

That's a good looking car and a great tail fin - how's the stall characteristics?

I wonder who that might be (sarcasm alert).  I can’t verify those claims, and know of no one jumping to those wingtips.  Makes me a bit suspicious of the true gain (if any) to those winglets.  

That said, I’ve had a ton of people ask me what advantage I gain from my sexy winglets.  I always respond honestly, nothing in airspeed, likely nothing in stability at altitude (the professed advantage).  But, I would install them on any Lancair IVPT purely for the visual aesthetics.  THEY LOOK FREAKIN AWESOME!  

My IVPT buddy in Australia, when hearing claims “you will LOOSE airspeed with winglets”, reminds our Lancair brethren that the two fastest turbine Lancair IVPT’s he knows of, mine and the late John Cook’s, both have winglets, and mine also has TKS!

Yeah, I put them on to soon in the ownership of 252AD so I don't know if they made any improvement in performance. I like the look of them and they include the LED Nav and Strobe lights. 

They don't extend past the aileron but are flush with the trailing edge.

 

How have they held up after 3 years in service? Looking to upgrade at my next annual.

Excellent! I'm happy to have them, and haven't had a single issue with them.

Welcome aboard FbN.

The modern wing tips are awesome...

The company was displaying their wares at Mooney Summit a few years ago...

@FlybyNite did you get a quote from them? I have a J with flat plates - curious what cost would be to add them as well.
