Built from Reed plans a ~74 Weeks Solution Biplane. Comes with what I believe is a 4.2 Sachs with electronic ignition. I will not say this for sure other than the props I found for it were a 24/10 and a 22/12. Comes with Hitec servos. This plane has not flown for several years and the batteries, fuel lines must be replaced. Asking $500/OBO and must be picked up, no shipping from the Detroit, Michigan area.
