Helton Lark 95
When Culver went out of business in 1946 the rights were bought by Superior Aircraft Co and then sold to California Aero Co of Tracy. They revived the model in 1966 as the Helton Lark 95 with a 90hp Continental C-90-16. Dimensions were similar to the Cadet, though the overall height was 6ft 10in due to the tricycle gear.
There is some doubt as to how many Larks were built, but seventeen constructor's numbers were allotted and not all may have been completed. The last to be built, c/n 9517, was N5017J.
Further developments on the drone theme followed the PQ-8 and the NR-D was built as the PQ-14A and PQ-14B for USAAF use and as the TD2CA for the Navy (which used a few TDCs from PQ-8 contracts). About 2,570 were built for use by the two services. Basic power was the 150hp Franklin O-300-11.
Post-war limited type certificate LTC-28 was granted in December 1947 and a few were registered, there being eleven listed in the 1959 statistical survey, and one, N4744N was still in existence fairly recently There was a strong similarity with the Cadet, but the fuselage was lengthened and a larger fin and rudder fitted to counter increased power, plus tricycle undercarriage.
