RE: VK Navajo???
I have the plans an looking them over there should be nothing touchy about the handling of this plane. I looked over the build an it seems to follow the plans I am looking at. Nice size an easy power setup. Of course my build will be from scratch, but I believe I could make a few changes with no effect on the design.
I flew the Nieuport 17 decades ago an my personal feeling is that it was not much more than a high shoulder trainer. Not difficult to fly but not an areobatic child either. Some what tame compared to most planes of the day. I think I could easily say an RCM Trainer is far an away a better plane in all respects.
I still am confused over the name, I did a search an still nothing came up in Cessna style as a Navajo. Hopefully from the factory knows more.
