Van's says a 200 horsepower RV8A will cruise at 210mph at 75% power at

Mine cruises at 182mph and climbs at 1800 fpm. Now, nothing wrong with
that performance, but still and all...The airplane is straight and
slick. No unusual drag makers.

Is the prop pitch adjustable? If so, where is it set? Is the engine
building to maximum rpm? If the engine is not being allowed to
develop full rated rpm, then the engine will not produce rated
horsepower. If the engine cannot develop rated horsepower, speed will
be affected.

If the prop is not adjustable, what is the diameter and pitch? How
does this compare to the recommended propeller?
