Yup… this guy is loaded for bear and he’s shooting live ammo. The practical max for non-forced induction seems to be around 120HP. The 33-pound device has been deliberately designed to work with a linear cam device to reduce the slings and arrows of torsional vibration… a personal bugaboo of Lance Wheeler’s (this guy hates vibra­tion like some ex-Presidents hate broccoli). Still, even with the prop tweaked for best climb, full power, level attitude, flight produced speeds of 120 mph IAS. An auto conversion that will 'actually' have the reliability of an aircraft engine will cost 3X to 10X the price of just putting a Lycosaurus in it. Each engine is … See our previous page for that.
