These all appear to be from my Master FTO. They were not meant for me, I will try to work out whose they are.
Ah that's why I thought some of the pieces looked like they were similar to pieces from a Master Curvy Copter.
I placed an order for a Master FTO a few days ago. It was order number 124642, line item number #333717.
Perhaps they are mine
I'll chime in again when I get my order.
