What it this?
Hi,
A modified Top Flite Headmaster?? The tail feathers are different than my old Headmaster and mine was a 3 channel Rudder /Elevator/Throttle job. Maybe the builder added ailerons wanting more control.
That's my best guess. The engine you mention is an OS Max 'S' series. These were really good running engines. I still have two .35's that I will never part with.
