The acceptable power range is 80 to 100 hp and the standard engine used is the 85 hp fuel injected Geo Tracker four-cylinder, inline, liquid-cooled, four stroke automotive conversion powerplant.

The Spad 13 has a typical empty weight of 550 lb and a gross weight of 800 lb, giving a useful load of 250 lb. With full fuel of 9 u.s.gal the payload for pilot and baggage is 196 lb.

The supplied kit included the Tracker engine. The manufacturer estimated the construction time from the kit to be 600 hours.
