RPO MODELS AVAILABLE
We have two versions of this popular device. The most commonly used one is the standard model. We added the Reverse type to meet the needs of modelers with different requirements. Such as left handed (timer on the right side of fuselage) or an inverted engine. Study the two versions carefully to decide which is best for you. The size is the same, only a mirror image.
