Being the kit does have a lot of small parts I'm still taking my time on this.
This session, I finished building and installing the landing radar - the 4 PE parts that look like shelves. I then started cutting out and installing the fins on the bottom (red arrow). These take time. Besides cutting the part off the fret you need to get rid of any nub that remains, what slows you down is the fin is prolly one 1mm or so long. Tough for my big sausage fingers. :P
Thanks for looking.
