Pre-takeoff checklist
If I were going to build a Lightning, my engine of choice would be a Rotax 915/916, but I may settle for the the XP320 or Titan 340 if that proved to be too difficult. I wouldn’t really want a Jabiru-powered one. But for anyone who has flown or ridden in one, did the performance match what the manufacturer claims? The website says it will true out at 130 kts with the Jabiru, 150 kts with the XP-320, and 165 kts with the IOX-340.
