In regards to weight, this is where I am right now. Unless I am forgetting something major, my total weight of current construction and remaining parts is 4864 gms. That is with the Plety motor CC HV-85 speed control, 8411SA on rudder, 9411SA on ailerons, 3421SA on elevators, True RC or Thunderpower pro lite V2 5000 mah batteries.. Not included in my calculations are aileron and elevator extensions, servo horns (not sure what I am using) and the battery tray/hold down. I doubt I will use the whole "plank" that was provided. I may make it out of something else as well. (also canopy mounting is not done yet.)
