update, I thought I would check the engine thrust angle first. I first made sure the plane was sitting as level as I could get it. Then I used a protractor with the string attached with a nut hanging down. I then put it against a level cabinet to make sure it read zero. Then I put it against the hub & to my suprise it read 4 degrees down thrust, I had to lift the BOTTOM of the protractor to make it level. That seems quite opposite of what the plane was doing in air, any throttle at all it went straight up & I mean any throttle. I guess my next project will be what capinjohn showed in those pictures & try to figure out that method.
Dave,
As suggested above, I would verify any radio mix for the throttle first; second, I would make sure about the CG location.
The rig for CG is very precise, but it is useless if the location of the CG is wrong to start with.
Specifications:
Wingspan 73"
Wingarea 1025 sq in (66sq dm)
Length 68"
By looking at the pictures of the manufacturer's website and going back over the dimensions and proportions that we used earlier here, it seems to me that we are still off about the proper CG location.

What about contacting the manufacturer to double check what the manual reads?
