The building of the kit was made some times ago...
Some problems to remove the tiny parts from the sprue and to place them on the kit; but finally all was OK.
The antenna seemed to be too thick to me, so I've replaced with steel wire.
Only a major probelm: the tracks. On one side all ws OK, but on the other side there was a little space... I've recuperated a part of track from my spare box and placed them where needed...
