Props for Flyguy

Many of you know that I was out of the hobby for 20 years so I missed the whole 4 stroke and slow fly revolution. This revolution included low wing loadings, aft CGs, large diameter props and low prop pitch. I can see how many could view Flyguy as another slow fly profile foamie. Flyguy is not a slow fly plane. His flight surfaces are out of the prop blast and are effective only at velocity. He flys more like a balsa shoulder wing trainer with ailerons. I mention this because I think that the turn problems reported may be due to people trying to set Flyguy up as a slow fly plane. The logic is there..... Depron = slow fly. For Flyguy62 and Flyguy46 you will need around a 1000kv motor and 6-7 inches of prop pitch on a 3S battery. At the motor wattage recommended, the prop slot pretty much dictates prop diameter. On Flyguy31, I run a 2500kv motor at 2S with 4.3 inches of pitch, perfect for the GWS 5x4.3 prop.

Can you please clarify the thrust angle?
Here is what is written. "Center of motor should be 1/4 inch above center body plate centerline. Thrust line should have 0 side thrust and about 4 degrees down thrust vector. Since Flyguy is a pusher this means the motor should be pointed upward."

Ok, the 1/4" above center body plate... In the picture he is upside down. Is the motor mounted above the plate as in the picture which means the motor is under the plate when right side up?
The reason I ask is I'm about to mount my motor. I have a 31" Flyguy kit from birdofplay. With a 5" prop, It can't be mounted above the plate when right side up. The prop hits the shoulder plate. So the motor must be mounted closer to the chest plate. (I think)
Plus the prop slot isn't 5" wide but is easily cut bigger.

The 4 degree down thrust vector... Is this measured when he is right side up? So the prop thrust is pointed down 4 degrees? I really think it is but before I glue in my motor mount I want to be 100% sure.
To build my motor mount Flyguy has to laying on his back. I have to work on what would be the bottom of his chest plate. I'll only have one shot at getting this right.
My motor doesn't mount like yours so I need to design a different mounting system. I really only want to do this once...
Thanks.

In the build thread, I chopped down the height of the side to lower the shoulder plate. My 5" prop is really a GWS 5" which means about 4.8". The thing to do is mount the motor as high as possible, centered or slightly above the center body plate, and also incorporate the 4 degrees of down thrust.

Plus the prop slot isn't 5" wide but is easily cut bigger.

Once you have the structure built, cut the ends of the prop slot away.

The 4 degree down thrust vector... Is this measured when he is right side up? So the prop thrust is pointed down 4 degrees? I really think it is but before I glue in my motor mount I want to be 100% sure.

When the motor blows air, it will blow it upwards at a 4 degree angle, toward the top/arm plate.

Please ask more questions, if you need to. Best.

I'm on that same "glue on the motor" step, with the same apprehensions. Can anyone provide a close-up pic of the motor in its proper position (I seem verbally, but hopefully not visually impaired)?

Edit: Oops, (danford1) just found pic #43 that was taken from the bottom and #44 from the top - thanx Otto.

Rshep, Where did you find that picture?
Can you post a link to it?
Thanks

Picture #29 may help too. I'm going to add a drawing.
