RE: How will it fly, what should I expect?
Dave congratulations for your now test and flown new invented plane. I am far to be an expert but I think that some incidences have to be adjusted. You can start with the engine incidence as this is the easiest way (install some washers between the firewall and the engine mount).
Have you made some verticals?
Does your plane goes stright up?
How does it fly inverted?
Good luck and happy landings.
