Fodder for insurance attorneys,
In all answers to this posting I missed a very important factor. Design!
most people who like to fly big airplanes have moved up the weight ladder
by experience, not necessarily design background and knowledge of all the
Just for that reason it is not safe to mess with the larger weights. After
all, when a weight limit is not accepted now, it will not be then! Design
dexterity means to get the most out of your limitations, which does not mean
to build to the limit, but to design and build within the limits, which are
such, that airplane construction engineering grades and homologation
programs are not required for our designs.
As weight and sizes go up, so do wing loading, take off and landing speed.
Next we will need larger flying fields to fly our no longer model- or scale,
but mini airplanes.
For the smaller sizes, Mv^2 of course is a major issue too. We should all be
aware that a turbine powered plane of 10 lbs. flying at 180 Mph is like a
cannon shot when a major control servo goes astray.Even the best pilot will
be out on a limb if this ever happens during a low pass at a show event.
Over here in the Netherlands, my private hobby shop owner builds the very
powerful and reliable ATM turbines and he is a very good flyer. I sure hope
he will never experience a glitch that will cause harm to anyone.
The point I am trying to make, is that unless we are aware of what we really
do, our actions may backfire on us in a way we might very well be sorry
