Yes I've seen a DS soarer blow up on the radiocarbonart videos.
My friend flies a Diamond dust with a hot 40/pipe and pulls hard
coming straight down full throttle. He often lands with no covering
left on the bottom!!!
Rebel the metre a made was crude. I tested some alum. tubing to
the bending point to get an oz/in figure.Then as an example one
was to see if 20 g's was exceeded simply put one twentith weight
on a supported tube in the plane.
A real seaplane builder said a real g-metre is small and simple.
The plane I pulled 17 with was a 2-metre Falcon glider,RG-15 wing
with a good spar vertical dive with a 25 on a pipe. Probably pulled her out at 100 mph+-
On 30% planes the speed is lower but I'm guessing I've pulled close to 15 with my 80" Extra. I do snaps at full bore on the level
and a blender with power on,once blew the top of my rudder off!!
Anybody know how the tailfeathers are loaded in flight???
