Dynamic soaring is the defination of pulse and glide, at least at at model scale. Cant comment at full scale, havent seen them succeed.
Aircraft engines are mirrors of 1940's car engines, same characteristics, just newer parts.
Friends compression was 6:1, his prop windmilled during glide after stopping. Mine was "high compression" or 8:1, rated for 125 hp on 290 cubic inches but only ror 5 minutes.
