Saito FA-40A

Back by popular demand. Saito's FA-40a will turn an APC 10 x 4 prop at 10,500 rpm! The FA-40a has nearly the same mounting dimensions as the FA-30, so the larger engine can easily replace a .30 in an existing model with a little rework. This isn't a bored-out .30; the dimensions and specs of this new design fall between those of the .30 and .50. With a power increase of 30 percent more than the .30, but a weight increase of only 15 percent, the 40a boasts quite a power-to-weight-ratio improvement!.
