  • $\begingroup$ A 2HP engine for an ultralight? Is this serious? Do you mean a drone? $\endgroup$ – Ralph J Sep 20 '20 at 19:09
  • $\begingroup$ The Lazair had two engines or 9.5 hp originally, and that was marginal. You generally want 25 hp or better to have decent climb performance carrying an adult human. $\endgroup$ – John K Sep 21 '20 at 3:09
