My construction isn't just right....it is pretty darned close to perfect. My precision is within a few thousandths of an inch. But so what??

When one flies the types of models I do, (top level aerobatics competition), one tries to extract the absolute maximum performance out of a model......it minimizes the workloadon me, thepilot, in the middle of comp flight.The final decalage and any other angles for that matter are finalized over time as the model is trimmed for perfect flying. Iabhor using electronic fixes for anything we do in the flying. It is the last resort, not the first

That's where having built in adjustable wings, stabs, engine mount, and dihedral come in very handy. I know this is advanced stuff and the average sport flier would never even attempt them or has even thought about them. But that's how the game is played whereI play.....

But that's waaaayyyy over the top for what Bill was asking in his original post, No? For Bill, getting things back to some semblence of correctness is most important
