RE: CMP/GSP Spitfire
I believe Pete has/had some mechanicals in his originally....right Pete?
In the UK Flair (Importer of the same Spit) have introduced a set of heavy duty retracts for the ARTF range. These are mechanical jobbies too and retail at £25. Maybe these are the same as the German ones. I am tempted as this is quite a saving from buying air retracts here in the UK, but dont want to get the wrong ones...which is why I am following this thread with great interest.
See....
