RE: False firewall
G'day
My reason for doing this is a bit unusual so I am not surprised you are not going to do it. I currently have four Kadets but this one is going to be my experimental plane. It will have two different wings and initially will have a Saito 90R3 radial engine inside a round cowl. Later it is going to become a camera plane with the camera where the engine normally is and the engine either over and behind the wing or it may become a twin engined Kadet.
Cheers
Mike
