And I'm fairly certain he's no where near 100% on the throttles.
we watched the RC Jets in St Charles last year and they had a 200 mph speed limit at that field because of the surrounding area. The pilots there said many of their planes hit 300mph. Not scale 300mph...actual!

At 200mph those little jets clicked by in a blink of an eye, nearly too fast to photograph! It cool stuff if you have several thousand dollars just laying around!
