I now sit here wondering why all this nit picking for an event that was a local event to start and has never become an official AMA event.   Huh

I've been on internal corporate engineering standards committees.  Things that really matter -- things that keep circuit boards from bursting into flame, or software from locking up before it even has a chance to blink a light -- those things get agreed on immediately.  Things that are just a matter of style, like how you indent your software code or whether you line up your circuit elements neatly on a schematic -- those things get argued over endlessly.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

If you buried a 1/16 or 1/32in. carbon strip from the stab to a motor mount internally with almost any other fuselage structure I suspect it would supply all the stiffness needed for good performance.  I base this on having built quite a few 3/4in full length fuses with merely 1/16 balsa sides and a foam core.  If you make a bit taller, say six inches or so, it is already very stiff.  Adding a spine could only make it better.  Add some carbon tissue on the outside for additional strength and a good paint base.  The spine doesn't have to be on the outside, although that is the simplest way.  Maybe corrugated sides?

Many Profile events I've seen were won by ARF or ARC P40s.

Different strategies can reduce tail twist. Take your pick. A reliable engine run can be more tricky. My most recent profile adventure needed bubble wrap to settle in.
