I have a few questions.... did you also hollow out the Toybiz wheel in order to make the turbine blades, or did you leave it as is and use the rim/hubcap area as a guide to make the nose cone? I was also curious how you made the blades for the turbine?
I just turned the toybiz over and poured resin in halfway to cover up the axle hole. For the turbine blade it was a bit tricky. I took sculpting clay and start by pushing the toybiz backside in to give me the diameter. Then i slowly used a sculpting tool i made to sculpt the blades. When i had it looking right i poured resin in . The front cone i used a crazy glue tube( one with red cap)as a mold. I.filled it with resin then unmolded and sanded the tip round...makeing sure to get the right" droup" at the end.
