Larry Hermansen of Lake in the Hills, IL, built his Kaos .90 from plan #FSP11841. It weighs about 11 lb. and is powered by a Saito 150. “More than needed, yes,” writes Larry. “However, when taking off to the east at our field one has a tree line 40 feet tall to clear immediately after takeoff.” He also has a .40-size Kaos powered by an O.S. 50. Both models are Monokote covered.
