Me thinks something is lost in the translation here......

In one of his posts, I think Mr. Speedman is using the term Q40 to mean 'Quickie 40 engine' when the rest of us know Q40 to mean Quarter Midget 40. I think there's some comparison of apples and oranges going on here.

The bottom line is speed clocked in a dive means Diddly-Squat ! You must properly radar gun a model in level flight upwind and downwind in a series of readings and determine an average.

My friggin' car keys will do 200 mph in a dive from 1000'

Put yer MVVS on the course with three other guys and let's find out what speed is.
