Pretty simple. Black Magic with the fuselage not being glassed and painted however just covered. The tuned pipe area is glassed for protection. The engine is a MVVS 26 petrol with a Karl Mueller header, ES composite tuned pipe and Hyde mount (type A). I am currently using li ion batteries for rec and ignition but will change out to li poly for an addtional 3 oz weght savings. I am also using fiberglass landing gear but am changing that out to carbon ES gear to save another 2-3 oz. Fuel tank size is a 12 oz tank will get you in excess of 15 minutes of flying time. I am using the PT models 18-8 carbon prop which seems to give consistant speed and good vertical. The plane should be around 10 lbs 8 oz by weeks end.
