Looks to me like it would be for setting reflex.

So the flat side (top in photo) goes into the wing in the elevon crack, and the deflections should mimic the ends of the paper? It looks like the downward deflection is just slightly less then the upward, if there is any difference at all. Like almost no differential. It's been a long time since I set up a wing so I forget if that is normal. Perhaps it's just there to say, "This is the ideal amount of throw" and with any less or any more you might have issues.

It is for setting reflex. If you ran a straightedge under the wing, the elevons would be up-trimmed about 1/4" off of the straightedge. With that white card on top of the wing, with the line on the hinge line, the card will contact the top of the wing and top of the elevon.

Well the Dom had a brief flight at Fermin! It was fun being a part of it's journey and a part of the cause a fellow RCist held dear.

I may not be able to get to the post office this evening but it will be in the mail tomorrow for sure. That said I think the Dom is due for retirement sometime soon or perhaps for rebirth as the Dom 2.0. While I'm sure it was a fun ship to fly in it's early days it now takes an expert pilot and a fairly strong wind just to keep her up.

I'm not quite sure what I did qualified as flying it, but I did give it a nice chuck and wobbly trip down the cliff. (Thanks for warning me Tom! Oh wait you did ) I probably could have done a little better with another toss or two, but that was all the time I had for. I shot some video from my GoPo cam (iPhone held in mouth by tape) of the flight plus the retrieval! Will post it when ready.

Cheers!

Tom warned me too.

And like you, it didn't seem to help.

Seriously, how hard can a wing be to fly right?

Ok, here's the retrieval! Not for the feint of heart.

A couple questions to those who have set up the DOM in the past.
1) There is a little white paper in the box that looks like it's for setting up the throws but it beats me if I understand it. Can anyone help? (see attached below)
2) Is CG marked on the wing? I forgot to check although I doubt it needs any adjusting.

Lastly a question to Zipper and the DOM community in whole. I took the time to scan the log book and now have it in a PDF format I could post up here on the boards. Is that something that would be ok to do, or should it be kept as part of the experience of actually flying the DOM?

-Jonathan
If you could post the comments in the log book up here, that would be great.
The CG should be around 180mm to185mm from the LE at the root.

Jonathon, it looked like the throws were way too high. I flew it at Lilly's in about 10mph no problem, but in bigger winds like 15-20+ it really moves out and carves up some sky.

+1 on posting the log book comments. That is an equally cool part of the Dom, reading the log book and hearing of it's journey!

Tom, you are probably right about the controls. I had misunderstood the reflex jig and since it's been ages since I've flown my wing I forgot what was a good amount of elevon movement.

I'll see what I can do about the log book tomorrow. I just attempted to attach it here and RCG's is giving me a 3mb files size limit for pdfs and the file I made is just under 10mb.

Yeah, thats what I'll end up doing, just a bit lazy at the moment since it's almost 1:30AM here in SoCal.

Tom, oddly enough that trail is one of the better trails I've had to take there. Probably because it's used less and less eroded. The hiking pole really helps too.


I've split up the log book file so I could attach it here. Enjoy!

Tom, that comment from you had me asking myself all last night and this morning if I really was ok going home with my tail between my legs. From the brief flight I had, I thought trying again really would be a waste of time and all joking aside that cliff REALLY isn't fun to hike. Well I had planned to ship it later in the afternoon after work, and so it was still in my car when I hit Fermin for lunch. Even though I had my newly trimmed and programmed Speedo ready to test I really felt the Dom calling for redemption.

Checking the wind conditions and seeing it was at 14-16mph was the last straw and I undid my work from last night reinserted the Rx you had left in it (and which I'll be returning to you) and set her up. This time I figured out how to use the reflex jig, greatly reduced my 2 throw settings for both elevator and aileron and then there was nothing left to do but give it another shot and wow...

I can say she's not a real great inverted flier and tight rolls can turn into a windmill heading strait down, but for less tight quick and sharp aerobatics she flew absolutely beautifully. Being slighty on the heavier side she really carried momentum through turns and like you said, she really "carves up the sky".

I took another video and will post it tonight as it's considerably longer and would take a couple hours or so here at work to upload. I actually haven't checked it out yet so I'm hoping it turned out ok.

So it has officially been re-flown at Fermin and will be moving on to Cory and the Soar Utah 2012 event. I will keep it one more night though as I believe there were two (2) spare servos in the box, but when I opened it a little while ago I only saw one (1). It may have fallen out and be hidding somewhere in the crevices of my car or on the garage floor so I'd like to double check before taking it to the post man.

-Jonathan

P.S. Here's a few current pics of the box. A true part of the Dom's story and full of flavor. It now has an OCSS marker on it for good luck and continued good lift.
