I have a stupid but serious question (The model looks awesome and flys great) but if that's a scale Eurofighter model, and we are told the real one is so aerodynamically unstable and on the edge it can't fly without umpteen computers involved how come yours fly's without crashing with I presume no computers but you? Does the model have changed dimensions or is it a true scale of the actual airframe or am I being dumb? Cheers. MD
The very first thing that such planes we could radio controlled without any computers is, that we have not the heavy weight like the original one. This Eurofighter is Scale 1/6.5, so I have must a weight from 2.384 kg xD but this Turbine Version weights "only" 19.5 kg and my Electric powered same size Eurofighter weight only 15 kg. The Size is Scale till pairs of millimeters. Second is the airfoil is not original but very close to it.
The third thing is the Center of Gravity, the original can go much more backwards in a instable stage to get a really high maneuverable Plane at high speed Mach >1.0 and at it´s weight. So it´s not anymore stable to fly it the "old way" you must have a computer -> fly by wire...
@RWJets And so my next question logiacally is if you don't have the weight but a gas turbine powerplant then what is your power to weight ratio compared to the real plane? I bet your's is higher?
@md902A that I must answer with a no, My power to weight ratio on this clip with this turbine (it was a not so powerful turbine) is 1 / 0.71. The turbine has only max 14 kg of thrust. Because this Eurofighter was itself to heavy builded. But I has flown it also with a Turbine with more Power over 20 kg of thrust, it goes straight vertical and speed up.
My newer one is lighter but has also a other power plant look at my new clip: /watch?v=HRjUDwftI1E
