I just had the pleasure of cartwheeling my favorite plane: a Midwest Super Stearman with a OS 120 Gemini twin. I'm not sure if I can build up the motivation to graft the fuselage and upper wing back together.

I'm playing with the idea of putting the 120 in a GP Spacewalker. The twin should look alright and will provide ample power.

Can anyone give me the cowl width and max dimension from the firewall to spinner backplate ?

Has anyone else tried this combo?

Thanks,


Jim
