I t is a SIG 1/6, sig does not include the dummy in the kit, neither sell it as parts. There is no a dummy engine for this kit. Yes, it is the 72 inches wingspan. I will power it with an Enya 29, until I get an small 4 stroke. I don't need a picture of an specific model dummy engine, just a close up of the dummy of any model, sig or GP or else, so I can have an idea to build mine. Thanks!
