Hi,
I have a GP Lancair in the box. I am wondering if anyone has flown this plane with a Saito 82. I also have a Saito 91 which is the displacement everyone seems to be using.
Thanks

I am not sure if you are going to fly her comfortably with a SA82 ... I ran mine with a SA100 turning a 15x6 and that was really nice, no balance issues.

I guess I'll stick with the SA91.
Thanks

Has anybody tried the OS 55AX yet? I'm not too bothered about aeros of course as that isn't scale (and certainly unwise with the wing). I'll go with the .61FX if necessary, but I'd like to try the slightly lighter .55 and see how it goes... any thoughts?

Cheers,
Greg

Lighter for? It will not give you much savings on the AUW but then you may end up having problems with CG. Remember, your Lancair's rx batt is way back there. For me ... go with a 90 sized 2C, its more powerful than a 61 which I feel is not worth getting. Costs not that much less but for the same weight you are not getting the performace of a 90 sized 2C.

I have a Saito 100. It has plenty of power, infact you need to use throttle management. A pic of the Lanceair is in my gallery.

I have one with an OS 61 and it flies great. Believe that is also the engine recomendation from Great Planes.

I'll second the OS.61FX and in-cowl muffler. Good scale power
but not a rocket. Balance was achieved by moving the Rx pack
3/4 the way back to the tail feathers. As I said before
on the many posts concerning the Lance...I'll sure miss her![]

Another gentleman flies one with an OS .91FS Surpass
and it flies with a little more authority.. I.E. He's able to
fly wider loops , responds better on takeoff and
has better reserve power.

The beauty of the .61 setup is that it is completely enclosed
in the cowl and looks very clean....hope that helps.

Thanks guys for your comments. Actually, with the balance issues - even though the .55AX isn't that much lighter than the 61FX, it is at least a little. This can only make it EASIER to balance I feel. Also, I'm not planning on doing any loops or vertical stuff with this aeroplane as that wouldn't be done in the real thing anyway. Given the propensity of this particular ARF to shed its wings if handled harshly, I feel there's another reason to treat it a little gently. I'm really just after a Sunday-flier that looks the part. I have the in-cowl muffler that will fit the .55AX with just one extra mounting hole drilled in the manifold so it will all fit within the cowl quite nicely. My only question really that remains unanswered is:-

Will the .55AX have sufficient power for scale flight? From what I'm hearing, the .61FX has more than enough power for the job and for scale flight needs to be throttled back anyway.... Normally, I'd just go for the most power I could fit under the cowl, but on this occasion I'm thinking more conservatively - definitely out of my league on that score!!!

Thanks again,
Greg

Mine hammers on an OS90FS - I'd have thought a Saito 82 would have been heaps. Mine does huge loops from level on the OS, so not sure why you'd need more. Most time spent doing fly-by's with 1/2 flap at about 1/3 throttle - sweet!

A 90 2 stroke sounds like a good way to get in on the "I folded my Lancair" threads.....

I went with the Saito 91. I had to add a an ounce and a half to the tail. I am finishing up an on-board video from the perspective of the cockpit. I'll post a link when I finish.

Defnitely, I joined that club with just a .60 on it! Whole 'nother subject...
I'm now looking for a new home for that motor.

Yep, they all come out nose heavy even at the low range of the engine recommendations.
Sounds like a lotta fun. I always wished I had a little more power for go-arounds
and takeoff but then again, I had just enough time on it to figure out how to land
it right and boy is that where I fell in love...very scale landings!

Here is the Lancair on-board video I promised. I fluffed it up a bit so I wouldn't have to cut the music short.
Hope you like it.

Very cool CAsniffer. Nicely done. Enjoyed the storyline and it really felt like I was watching vid from in a full-size plane. Love the panning action.
Thanks for posting.

Best video EVER CA!!![X(][8D]
How did you know the pan position?
Was there another cameraman or did you use
video goggles or whatever you call 'em!

That is just freakin' too cool! I always wondered
what it would look like if I could miniaturize myself
and step into a model well, my prayers have been answered!

Quality Stuff![sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif]

Sportflyr,
I controlled the camera panning with a knob on my 9C. I converted a Futaba S148 server to 180 degree rotation. They're cheap and fairly easy to convert and better than a retract servo because you can't stop a retract servo anywhere in its rotation. I set the end points for the servo in the transmitter (just like you would on a control surface) and hooked it up to the TV to check the positions. I was alone at the flight line while the rest of the guys huddled around the camcorder to watch. I didn't fly-by-video because this plane moves too fast. I have flown my 80" Cub from the video alone. That was cool. Took off and flew around, but landed with my eyes on the plane.
On one of my earlier flights, I was able to follow a fellow club member's B-25 for a few seconds. Its very difficult to get right behind another plane and maintain a safe distance unless you fly-by-video. I'll practice at that. A club member owns a "repaired" Lancair that I am considering buying it as a camera plane. About 8 inches of each wing were broken off and they weren't repaired straight. I might "clip" the wings and see how it flies.

Thanks for the complements, guys.
