RE: What would you build for these beasts?
Just for completeness, both Brushfire and EU-1 have been designed 1978 when short-strokes reigned. The EU-1 article mentions a Rossi, which is more of a screamer than the Webra. You might be better off with the Webra and maybe EU-1A and surely Brushfire should be possible. They have this additional slow-flying ability, but a Matt design might be more interesting...
Expert's opinion on that?
