Lenny,

Good job! With the fuselage laying flat on the bench I just measured the same 77mm to the stab TE from the bench. That is in the trimmed position with the 105mm CG as I fly it.

Thanks!

Dick

Yep, yep. That's it. Could be that something was lost in the translation. I have 78mm. flat at zero with the wing. Would you guys believe I soldered the clevis coupler, then put everything on the elevator servo and it came up a perfect zero? First try, no trim. What are the odds of that happening again? Thanks everyone for helping me check my work. Nothing wrong with double-double-checking

Lenny,

I've never heard of anyone gluing the servo covers down with Goop. I would like to try this. How do you remove them without damaging them if you need to get to the servo?

If it's a flat servo cover (like one for top driven flaps), I sparingly spread the Goop all around the perimeter of the servo cover except for a small section left clear.
To remove the cover later, a small flat blade screwdriver can be inserted into the unglued area and easily worked around the perimeter of the cover to break the bond.

thanks Lenny, that is great info I can apply to several other sailplanes I have. I've never liked taping the servo covers down.

one more question. the 39mm 1506 motor doesnt look like it will fit thru the hatch opening very easily. Did you have to cut away some of the hatch lip in order to slide the motor in?

No, it will squeeze through the opening. No cutting required.

What a sweet model!

I got a bit more time to adjust settings today on the Orion and it just keeps getting better! I have my CG at 108mm now, which is still slightly postiive (will gradually pull up from a dive test).
About 3mm of camber used for slow thermal flight (the published 5mm figure is too much IMO) and she just hangs around in the slightest hint of lift.
My reflex setting is only about 1-2mm, which speeds the model up nicely while not giving up much glide slope.

Seems like NAN really did their homework with this model.
It's not often that a 2.5M model approaches the performance and efficiency of a larger moldie like this.
Thanks for bringing them in Bob!

BTW, I normally store and transport my sailplanes in model bags. They're not cheap, but they last forever and keep the models in good shape.
I did some searching for a bag to fit the Orion, but most were too big.
I settled on a 56" bag from http://www.hobby-pak.com/indexmain.htm. It's not quite as refined as the dedicated F3X bags that our favorite vendors carry, but it works quite well and the price is right.

Bag

I found this bag. More money, but it has a spot for the fuse, and they'll put back straps on it for you if you intend to backpack it like I am. This one is more for me since I'll be taking mine up into the Roosevelt National Forest on BLM land with my dirt bike. http://www.acewingcarrier.com/glider...-carriers.html

They look like nice bags too, and pretty reasonably priced.
Too bad they used some hokey PVC tubing as a mock-up in their pics instead of real models. I think it really distracts from their products.

I'm not really a fan of the "fuselage pocket" on the outside -- I prefer to have all the parts within the bag.
I don't use them for backpacking though, so that setup might work great for you.

Maybe Bob will have his bag supplier come up with a first rate bag perfectly sized to the Orion and other 2.5M models.

I think you'd need the 80" bag http://www.soaringusa.com/product.ph...&cat=46&page=1 I have one of these and they are very well made.

The wing panels and stabs would fit great. The fin would extend out of the bag though as it's too tall.

Yes, everything fits inside and is well protected. I had first bought this bag a while ago for a different model. I don't remember now what kind of separators came in the bag, but I know there was some velcro straps that I removed.
If it doesn't come with them, you do need something to separate the wing panels and fuse. I used some foam sheet, like a camping mat. You could even use bubblewrap or an old towel.
