Turbo Timber doesn't have LE Slats, it's a high wing trainer, doesn't need much skills to fly it. Lownverted, if you are such a great pilot to notice the difference show us the video footage difference flying LE Slats on any 70mm EDF hotted up jets. After building and flying at least 50+, 70mm ones I get a pretty good idea how effective the LE Slats are.

70mm EDF no Slats.

You got to build and fly them to know the difference.

Just another 70mm day outing.

70mm Harry

70mm Tajfun, hot as a missile.
