The APS "Peacemaker"plan was specifically redesigned by George as a free plan inclusion for "The Aeromodeller" at the time. Essentially it was the already established in the U.S. now legendary "Flite Streak" scaled down to suit the available power of the typical single and dual ballraced diesel competition combat engines of the day then in common use, viz. Oliver Tiger. With engine development over the years, any respectable contemporary muffled PB glow .15 has ample power to fly the design well as long as it's not built with leftover logs or an excessively doped and painted covering job.

Even a non-competition contemporary TBR diesel engine such as a PAW 2.5 diesel will fly the "Peacemaker"built per plan like a super hot combat model of its own era, and truly flies it way too fast with execessive power available to be enjoyable for ordinary sport stunt flying.
