For those who have been courageous enough to start this diamond: did you meet the same problem as I did while constructing the front part of the fuel tank?
In my opinion the vertical slot in part 2g is wrongly placed on the upper side; the opening should be on the lower side. (Please correct me if I am wrong!)
Fixing is easy: attach the upper part of the slot with glue while the part is still in the lasercut plate, cut out the lower slot after drying and remove the part from the plate.
(Hope to keep you informed about the building progress of this beauty!)
