i spent the past few weeks building one at 142% to get close to a 60 inch wingspan. i had issues getting skins to fit but after i found they weren't lining up with my frame i just cut them oversized and trimmed to fit.
other than that its pretty true to plans. i did remove paper from both sides of the skins before i covered them. i added blocks of insulation foam in the wings and glued in plastic drywall anchors for landing gear attachment points.
i also adapted it to have removable wing. the wing has two blocks of pink foam glued to wood spars that fit inside the fuse to line up wing and prevent rotation.
it's grossly overpowered and 6s capable. i'm hoping 4s will be adequate but if it needs more power, it's available.
4.5 lbs auw. haven't fully charged batteries yet to test power output but i'm confident it has enough.
now i just need the foot of snow we got this weekend to melt so i can see if it flies.
