I have an early Sapphire as well, still haven't flown yet, want to get my experience up a bit first.
I've heard of someone who fitted a simple flaps/form drag device to the wheel struts, and also another version that pops up behind the pilot in the area between the wings.
My Sapphire has the motor positioned the right way up (not inverted) so this creates more drag than others and supposedly easier landing characteristics.
I dont have any pictures so hope someone else out there can help.
Do you have a copy of an operating handbook ?
