The photo of the single fuselage looks like a Summit II or III designed by Ivan Kristensen. The SBA is a fiberglass 'knock-off' of the Blue Angel. The Career is a fiberglass 'knock-off' of the Curare. I can't remember who kitted the SBA and the Career but they were sold by Mutchler's hobbies in Indiana (i think??).
My best guesses anyway
