And I still HAVE that Space Bug Jr, and the Firebaby it was mounted on. It served yeoman duty in sport FF models and a slew of half-A CL models, including the Wing Ding machined balsa kit, which (no surprise here) I still have. All with holes drilled in the firewall for the intake. I think us model builders all have a variant of the same mental illness that causes us to keep stuff for 50 years that we have not used for the last 45 years. Did I mention the Green Box Nobler kit I have had since 1963, that I bought at the 1963 Nats in Los Alamitos?
