Glow, gas, and electric size brackets published for Balsa USA radio-control airplane kits. A kit rarely names one motor it names a range. Use the filters to find kits that fit an engine you already have.

Ranges come from the current balsausa.com product page when that page states an engine, and from the 2019 Balsa USA catalog when it does not. They are the manufacturer s brackets, not a promise the cowl, mount, or tank will take a particular brand. Always check the live product page before buying an engine.

Electric guidance uses published flying weight against common watts-per-pound bands (scale ~140 160 W/lb, sport ~100 120 W/lb, trainer ~70 80 W/lb) and Innov8tive Designs Cobra motor chart where noted. A 2-stroke is read at roughly 2,000 W per cubic inch and a 4-stroke at 1,500 W per cubic inch. Motor weights are motor only. Innov8tive did not assign these motors to these kits.
