Smith, a retired Army Warrant officer who has already built an RV-6 (and whose wife is now building a Zenith CH 750 STOL with the 160-hp ULPower engine), explained, “I wanted to fly and build. I came up with this firewall-forward solution because the ULPower is an excellent engine, and it’s a good marriage to this airframe.”
Exact weight comparisons with the stock design are difficult, due to the fact that every airplane is a little different, but Smith notes that his RV-12, without fuel but with oil and full options (including carpeting and seat cushions), weighs 752 pounds.
Mounting to the same hard points as the original Rotax means the airframe design remains uncompromised, he noted.
The kit comes with all hardware, the cowl, ductwork and baffles, flex tubes, cabin heat valve, cable, hoses, master relay, spinner, Sensenich carbon-adjustable prop (Whirlwind and Warp Drive are also available), and a powder-coated mount in your choice of colors.
The standard kit is configured for a single ECU and electric fuel pump. Options include a second fuel pump, an oil heat exchanger, and an additional ECU. (The exhaust system supplied with the engine is integrated into the design.)
Smith has been flying his own RV-12/ULPower machine all summer, and has made detail improvements, all of which are incorporated into the latest kits, which are now available for $5,200.
