Hey cmoulder, what is the readings on your wings from the tip to the fuse? I have a pos 1 degree all the way across.

As the baseline (zero) reference, I assume you are using the canopy hatch rails? This is what I usually go by. Just as a wild guess right now, I would say mine is still slightly positive, perhaps 0.5 deg.

Jay, I will check it tomorrow and let you know what it is.

Hmm... well if yours is 0.5 with no modification, then mine has got to be less.
Now I'm really interested to find out, although I still don't think it is zero.

Just got to thinking, maybe the right wing was ok and the left needed adjustment, that would make more since seeing the plane would dip the left wing, it may need the pos 1 deg. on the left like the right had. i will try it like it is first then decide..

That can only mean the stab is also negative relative to the hatch, and sure enough if you look at it the stab incidence is also negative. I will post a photo shortly.
EDIT: to add photo
The photo was made with a 300mm lens to reduce the perspective error (with telephoto compression)
The top line was made through the stab with the stab in the actual flying trim condition
The bottom line was made parallel to the hatch rail
The middle line is a copy of the bottom line which was transposed without rotating, using Photoshop
I think this demonstrates the negative incidence of the stab, explaining why most people will need down trim with the elevator.

There is something weird about this model, because I measured the wing incidence relative to the hatch rails as a negative 0.41 degrees! (This is AFTER I raised the trailing edge.)

Jay, yes, I made sure the hatch rail was level first.
This why after getting that result I immediately checked the stab and was not surprised to find it is also negative to the hatch rails.
Now, I don't know what the wing incidence is - relative to the stab - but suffice to say it is very small. And the model now flies exactly as I like it, so I will let it rest there.

Okay, yes, the elevator is also neutral (level) with the stab, so it also "looks" right when it is not in the air.
BTW, if you decide after all this (and I don't blame you for confirming first!
), the method I used to raise the back edge of the wing was to place a short section of 3/32" ply on top of the wing at the fuse and make a small reference line with a fine-tipped Sharpie.

I also have a Sig Somethin extra and it has a 1 degree pos from tip to the fuse, and this plane has no bad habits at all, just got it two weeks ago..

RE: Phoenix Extra 330S 60-90 Size
I have an o.s. 46fx on mine, could stand more power, i almost stuck my a ST .75 on it the other day but man that thing would be heavy.
It's 27 oz. w/muffler, the 55 ax wouldn't be a bad thought it's only 18.54 oz.
I have a 61 fx on a 40 size super chipmunk but it's only 1 oz. less tha the ST .75, THE CHIPMUNK WILL HANDLE THE WEIGHT BETTER, IT HAS A 63.5 INCH WING... The extra has a 53 inch wing

RE: Phoenix Extra 330S 60-90 Size
Any of you guys with the 91 FS, do you have enough power to hover or unlimited vertical, I can't decide to use a 91 or 120 FS. With the 120 I would have to re drill the firewall and butcher the cowl, I'm not so sure with the 91, the 91 might save me alot of hassle but I wanna go up to the clowds, unlimited Vertical!!!

Good thing about the 2-stroke .91 is that if you use a Slimline Pitts muffler, everything fits inside the cowl.
If I were doing a 1.20-ish 4 stroke, I'd go with the Saito 1.25 which is a lot lighter than the OS 1.20.
All IMHO, of course.

RE: Phoenix Extra 330S 60-90 Size
got my extra a few days ago, I think I'm missing a bolt for the pull pull rudder. any of you guys care to post a picture of your rudder, I'm wondering how I'm asposed to hook it up. I think that you need a bolt for each pull pull cable or if you just connect one pull pull cables on each sides of the bolt. I don't think you would put both on one bolt, the bolt is pretty short and it has a head on it, not much throw it seems like. Instructions don't really tell you where to put the bolt either.

RE: Phoenix Extra 330S 60-90 Size
There should be a threaded rod that looks like the control horn material, but is longer and has no scredriver head on it. What you do is drill a hole thru the rudder, slide the threaded rod through and screw on one of the cone-shaped nuts on either side of the threaded rod, then screw on the little blue collars with the hole for the linkage.
To find the correct place on the rudder to drill the hole, run some of the steel pull-pull cable through the plastic guide tubes then pull it taut so that it has a clean exit from the fuselage, straight back to the rudder. Make a mark on the rudder where the rod will attach, so that there is a nice, straight line from the servo arm attachment point to the rudder.

RE: Phoenix Extra 330S 60-90 Size
I am getting this Phoenix in today, with a Saito 1.25 waiting to go on it.
The 1.25 had been pulling a .90 sized Seagull Yak54 around, but I think this smaller lighter Extra will be a lot zippier.
Planning to assemble and fly over Christmas holidays. Hope to report back with grand success!

RE: Phoenix Extra 330S 60-90 Size
Hey Cmoulder, I did get a chance to fly this past weekend but really can't say if the adjustments helped, the wind was about 20mph with gust to 30, i tried some hard turns and never could tell if the wing would drop, the wind was really knocking it around.
Next time i fly I will let you know, should be this weekend..
Thanks, Jay
