RE: Airframe Identification
Don't think it's Phoenix. The stab looks way big in relation to the fin. The fin does not look to be the correct shape. There is a Phoenix 7 thread and you can see the difference there.

RE: Airframe Identification
Hi,
Looks like a Phoenix 7 to me:

Maybe the top of fin is not like it should be for a Phoenix 7 and maybe the nose is slighly short also.
But the restis surevery similar to a Phoenix 7.

It appears to be a Vertigo II. The big stab is a dead giveaway. Can you post some pics from a couple of different angles?
If it has a diamond shaped airfoil on the stabilizer, and a chin under the nose, that would clinch it as a Vertigo II.

This web page shows a pic of i believe, Mark Radcliff and his phoenix 8. Not a P-7 like it's labeled. I could be wrong on that. lol

The vertical fin is definite Vertigo II. Hard to see under the nose, but i'm sure it has a small chin and diamond shaped stab. Note that the rudder/Vstab had an option to key the tip into the Vstab. This gives it more of a P-6/7 look to it. See pic below (borrowed from build thread here)

What happened to the aft fuselage? Looks like a tire tread pattern as if someone drove over it.

RE: Airframe Identification
I'm the one who has the plane in question, the horizontal stab is diamond shaped like the Vertigo I or II, but who ever built it did not put anti-dihedral (? spelling) in the stab.

RE: Airframe Identification
Yup, anhedral affects different designs in different ways. There would be some airplanes that would suffer some degradation of performance. Anhedral is not a one-size-fits-all design parameter.

RE: Airframe Identification
True. On Curare it enhance this plane in several ways. I know - I had a Curare that I flew very much with. And I even "enhanced" a Mach 1 with negative dihedral, anhederal,stab and it worked very good on that plane also.
Hanno Prettner said in Model Airplane News Dec 1975 issue Curare construction article "Many tests where performed to perfect this new design [anhederal] concept. It was found that the airfoil was very critical of the stabilizer otherwise opposite results where obtained."
The advantages mentioned,optimum low and high speed performance:
- Landing performance was improved
- Even bigger advantage in figure M since oscillation after stall turn was eliminated
- Rolls was improved (much better then the Super Sicroly)
- Improved crosswind performance and smoothness in gusty winds

RE: Airframe Identification
As i was drinking my coffee this morning i observed something i hadn't noticed before. The birds that were soaring had their wings in a positive dihedral. The birds that were flying near and into trees had their wings in a negative dihedral position. I assume that for simple soaring the positive dihedral keeps them stable and level. Then for rapid turning faster roll maneuvering, the negative dihedral position is easier for them. Of course i could be wrong but it makes sense.

RE: Airframe Identification
Wilbur and Orville saw the same and designed the Flyer with anhedral. They quickly changed theirs minds to simply no dihedral, though time would show that humans need the stability of dihedral, especially at low speed and near the ground.
We humans just don't have that innate sense for instantaneous situational awareness down yet.

RE: Airframe Identification
It is there, (the diamond stab) enlarge the pic and look closely at the paint trim lines. You will see a distinct "kink" in the line at approximately 1/3 back along the chord from the LE. Also note that there is about 1/2" to 3/4" missing from the TE of the rudder. It should extend back further. Look at my drawing on post #11. The missing material makes it look funny.
