RE: Small Engine/Large Plane
Buzz,
It seems no one wants to learn to fly these days...
A Cessna 150/152 can climb at about 700 ft. per minute, at maximum effort and it does it with the nose barely over the horizon.
Most R/C trainers would climb straight up, lest be called 'under-powered'.
There is no reason one should not learn that a normal model must actually fly 'on the wing' and only 'a barn-door with an engine' (a typical profile 3-D plane...) should prop-hang.
Most .40 size trainers would take off in 40-50' of runway, if you put a 15-.19 engine up front.
They will also pull out pretty well, somewhat like a current airliner.
Dave, when was the last time you watched a modern airliner take-off from a noise sensitive area airport?
These monsters, at MTOW put their nose 30-40ยบ up and climb out at 4,000-5,000 ft./min.
Many jet fighters couldn't do this, not too long ago.
