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.

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.
