Olmec Head Posted August 6, 2020 Share Posted August 6, 2020 Looking at the pictures etc of the new Eduard 1/48 Spitfire 1a, I was wondering if anyone had decent information on when the undercart lever changed from the manual pump to the hydraulic system. It is often quoted as around the 175th airframe, but that is still in the early K series I think. Interesting the P9374 and N3200 rebuild/ replicas have the manual handle, which would suggest that the manual handle was later than the K series. Also the voltage regulator was in a lower position in early airframes and then moved to a intermediate position later on. The Scale Models Nov 82 piece on the Spitfire 38-40 states that the regulator had a low seat position for N3023 through to N3110 and then to the final high set position. Again does anyone have any info or pictures of these two early regulator positions please, i.e the initial and intermediate positions? Link to comment Share on other sites More sharing options...
Mark Postlethwaite Posted August 6, 2020 Share Posted August 6, 2020 (edited) My understanding is that there was no initial position and that the pilot was the voltage regulator for the K series by the use of a switch in the cockpit!

Peter Roberts Posted August 6, 2020 Share Posted August 6, 2020 Change over of undercarriage retraction system seems to have been around April 1940. The new system was probably not retro fitted to earlier builds. Link to comment Share on other sites More sharing options...
