Well, here's hoping.
Just do a straight forward build. No screwball control mechanisms. Use modern hardware. Don't over think the construction. No "full fuse built around a profile" nonsense. Pick an appropriate powerplant and stick to it. Don't try to change it to JATO or something. It doesn't need a hundred access hatches or gussets in it. Use known "numbers" in the flying surfaces.
When someone suggests something to you, don't get defensive or bitter. You may have a ton of years in model airplanes, but by your own admission, it's not in U/C stunt planes. You obviously know how to cut and fit parts nicely so stop worrying about being SH teacher and just finish a model.
And most importantly, FLY IT! If you don't want do it, have someone else do it. At this point, photographic evidence will be required. (I'm not kidding)
