Thanks for the info keppel, I'm just past 50 myself.  You have some great models there, and yes, you know it's not going to "fly" but you have not pretended that either - guess it must be antigrav huh?  I really like the GS-78 too.

I sort of plan to be making stuff for sale here in future - it would help to have a little help though, I've got you as a favourite artist now :)
