Too bad, the Boeing 747 is the only one with ~30% scaled down size (I tried the same video with the ~1400 units long AN-225, but it was simply annoying).
After the early enthusiasm, I checked the replay and the video again. Things that should be fixed:
.RES: mass (stupid /me, 1 smu is not 100 kg, but 45 - it means 187 smu instead of the current 85...), wheel positions (forgot it somehow), grip (should be decreased a bit, the real Ikarus 260 can't complete a sharp turn at 80 km/h); minor: speedometer needle is too short between 80 and 100 km/h
.PVS: steering wheel movement (the ins2 bitmap seems to be too big)
.3SH: "transparency" of the bodywork (right wheels are visible from the left - through the left wall of the bodywork)
