I can probably take high quality photos of the manual and email to you . Since you are past the assembly stage, you'll probably need just the last pages on trimming and setting up the plane.

There are many warning notes about stalling/slower acceleration/keep airspeed up etc. due to higher wing-loading and larger frontal area. I would take that advice!

Another word of caution - I remember the interplane struts on the sides are attached to plastic support strips on the wings. The plastic support strips glue to the surface of the foam covering material using CA, and the plastic is cut/bent upwards to make attachment points for the structs. This method/material is not reliable at all. I used tape to reinforce the plastic support strip (taped it around the entire wing) for better attachment. You might want to check that area.

Email me if you need the manual!
Best of luck,
Matt
