RE: 250 mph speed! - German SPEEDCUP 2006 scheduled Sept 15th 16th 17th
Congratulations to German fellow J. Weirich for his formidable 394,1 kph run. The engine is a highly modified OPS 60 VAE. He makes everything (plane, props, engine parts machining &mods) by himself.
Because his wing load was above 75 grams/dm^2 the FAI world speed record for IC engines is still unbeaten:
FAI world record F3 Open (No.145): 343,92 kph
