Default Almost ready for test flight

Speed freaks,

I caught speed fever last year, and I can’t get going fast enough. He is a picture of my 80” Lancair IV with retracts that I hope to test fly next week. It has a YS-140L for power, but check out the Tartan Twin next to it. Should I or shouldn’t I, that is what keeps going through my mind with the Tartan. My 100” Lancair ES with a YS-120SC is a speed demon at an “estimated” 120mph, so the IV should really get moving. I will post the results after the test flight.

Beautiful! Can't wait to see the maiden video!! hint hint.

Looks like you didn't have to do too much to the cowling to get it to fit.

I have an APC 16X14 to start with, and then I will try a 14X13. I want to push it, but I don't want to kill my engine. As far as the Tartan goes, it fits perfect. The big question will be what prop I can use with the beast, it will swing a 22X10 with no problem, I will more than likely have to go to a three bladed prop with a huge amount of pitch.

I tried an APC 14/13N for my YS110 P-51 combo but it was a little much. The 14/12 works great and stays below 10K. For the 110 anyway.

By the way I really like the red and white paint scheme. I saw the electric version of that arf in a magazine with the true red and white paint scheme. The 140 will truely do it justice.

This isn't the GP ARF, it is from my own molds and is quite a bit bigger than the GP version. Flys better as well hehehehe. I will see if I can get a picture of both for a size comparison.

Here are a few pictures of my Lancair IV right before the test flight. I put two flights on it, and all I can say is there is nothing like a low FAST fly-by with the gear up and going 100+mph. I only with I had a speed gun out there to see just how fast it was going.

Congrats on the maiden there! That sure is a beauty... Nice air-strip also...

YS-140 you say? AWESOME

Keep us posted if you decide to shoe-horn the twin in there...

Gorgeous plane! I would love to see a video.

P.S. I just purchased a radar gun on ebay. We will see how it works with rc planes.

I am tired of just guessing my aircraft speeds.

Congrats........

looks like a real nice bird. I've always like Lancair. Some of the Reno variations are very interesting subjects.
