RE: Yellow A/C Spitfire Retracts and engine.
Do not forget [link=http://www.unitracts.co.uk/]Unitracts[/link] in good old U.K. They produce very nice U/C units and if you ask them you will get the scale 96 degree retraction angle. As far as I know the Robarts are 90 degree retracts. I haven't seen the Yellow Aircraft U/C live, but from the photo they also appear to be 90 degree units. Please correct me if I am wrong.
