According to Don Anderson at Great Planes, at the IMS Show last week, the Staggerwing will be red with black trim.

It is designed for a 120 sized 4 cycle or a 160 sized twin four cycle.

And look for it in April. Maybe at the Toledo show on display.

The OS 160 twin fits in the cowl, so maybe a Saito 3 cylinder will fit too.

The OS 5 cylinder is "...much too big, size and power-wise..." according to Great Planes also.
