Twin
I'm not sure really what that twin is. That photo is of a mall show we had last year and I haven't seen the owner in awhile. If I remember correctly it is a C-123 and he built it from plans. Hope that helps.
What are you guys powering your Bees with? I put a OS .26 in mine and has plenty of power. In fact it is rare I fly full throttle, it's more fun to go slow.
