I fly single stick, so I can screw up the rolls equally well with either control layout.

The "mod" that interests me most would be laying the engine flat and doing another coke bottle cowl that blends it into the wing.

To fly a normal "Speed Pattern" with this thing, the elevons just barely need to move at all.
Too bad the old Blink build threads are still in hiding because I'd like to review some of the control linkage methods that were used.
I'd like to use Spiderline pull / pull with 1/16" ply control horns. If I went this route, I'd be reluctant to fly the model too aggressively [until I got thoroughly bored with it].
