Ex VZ728, G-AGOS. Built in 1945 as the RS3 three-seat trainer, and later rebuilt as an experimental prone-pilot aircraft redesignated as the RS4 Bobsleigh. Withdrawn from use in 1973, the registration was cancelled on 9 November 1981. After a long period of preservation it was restored as G-AGOS on 14 July 2015 and returned to flying condition at Spanhoe by Windmill Aviation for owners Leicestershire County Council. It has since moved to Newark Air Museum for long term preservation as a static exhibit, making its final flight on delivery to Newark on 19 August 2022.

First registered in 1945 and owned by Air Couriers at this time, so likely in their hangar with Viking XB-FIP behind undergoing overhaul. Last flight took place on 19 August 1922 from Spanhoe to Newark Air Museum then cancelled by the CAA.

Used for prone pilot research then film work. Looking very neglected with a soft tyre and in a rather scruffy hangar.

Initially used by RAF as VZ728 for prone pilot experimental flights. Later used by Kemps for aerial survey work. Now stored.
