Work has been really slow for the last few months, so I had to do something to keep my sanity..Full size BF-109G instrument panel, why not... while working on it I suddenly realized how big the Revi gunsight was and thought hmmm..make it work ? It's amazing what you can do with a really good color copier(instrument faces) built every thing from scratch with the exception of the screws and nuts...started the wind screen but work picked up again....
