From 1959 Rausch Engineering Inc. of South San Francisco, California, converted N8186H to tricycle undercarriage, using forward retracting main gear from a P-51 and rearward-retracting nose-leg from a T-28, adding a {{cvt|3|ft|2}} nose extension, {{cvt|4|ft|2}} rear fuselage extension, re-roofed fuselage for increased headroom and enlarged cabin windows. The modifications did not obtain FAA certification despite 58 hours of flight testing, with the aircraft eventually being broken up at Antioch, CA, in 1978.<ref name="aerofiles Ra">{{cite web |url=http://aerofiles.com/_ra.html |title=American airplanes: ra - ri |publisher=Aerofiles.com |date=18 January 2009 |access-date=2011-03-16}}</ref> ;SFERMA-Beechcraft PD.18S :Modification of Beech 18S powered by two [[Turboméca Bastan]] [[turboprop]]s<ref name="jawa61p67">Taylor 1982, p. 67.</ref> ;Volpar (Beechcraft) Model 18 :Conversion of Model 18 with nosewheel undercarriage<ref name="JAWA 65 p316">Taylor 1965, p. 316.</ref><ref name="JAWA 82-3 p483">Taylor 1982, p. 483.</ref> ;Volpar (Beechcraft) Super 18: ;Volpar (Beechcraft) Turbo 18:Beech Model 18s fitted with the Volpar MkIV tricycle undercarriage and powered by two 705-hp [[Garrett TPE331-1-101B]] turboprop engines, flat-rated to {{convert|605|hp|kW|abbr=on}}, driving [[Hartzell HC-B3TN-5]] three-bladed, reversible-pitch, constant-speed feathering propellers<ref name="JAWA 82-3 p483"/> ;Volpar (Beechcraft) Super Turbo 18 :2x {{convert|705|hp|kW|abbr=on}} [[Garrett TPE331]] ;Volpar (Beechcraft) C-45G :C-45G aircraft modified with tricycle undercarriage ;Volpar (Beechcraft) Turboliner : 15-passenger version of the Turbo 18 with extended fuselage, powered by 2 705-hp [[Garrett TPE331-1-101B]]s<ref name="JAWA 82-3 p484">Taylor 1982, p. 484.</ref> ;Volpar (Beechcraft) Turboliner II :Turboliners modified to meet [[SFAR 23]]<ref name="JAWA 82-3 p484"/> Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
