When 300km/hour is not enough, there are some ideas to create jet-powered aircraft using Shark design, so You could fly 400-500 km/hour according to used engine.

Price-induction jet looks nice for that purposes :
At Take Off Power, you can get up to 255daN, consuming 80kg/h of fuel for the DGEN 380 and 330daN with 100kg/h fuel consumption for the DGEN 390.

of course - this kind of aircraft cannot be called Ultralight, although its empty weight could be very similar

During weekend we approved ultimate loads for ailerons and flaps till 120% above ultimate loads. Both were approving ultimate loads without any permanent deformation.

Finally we tested positive loads on wing, increasing loads till structural crash. This test approved loads increasing adequate increasiong of maximum take-off weight above 600 kg. Altough of that, critical part will be for next serial production reinforced.
