Tom Beck posted on Facebook about the Heinkel Wespe which was designed but never built - a VTOL concept plane in Germany around the end of WWII. https://en.wikipedia.org/wiki/Heinkel_Wespe (related concept was the Lerche - https://en.wikipedia.org/wiki/Heinkel_Lerche). Anyway, he challenged the person who had made the Coleopter so of course I had to step up...
Not sure if this would fly or not but here is my first prototype (made early this morning and tonight after work)... This was never built so all that seems to exist are some rough scetches (hence variations in the designs above). Built for BT60 body tube with motor mount sized for D-size engine. Should let me put a couple of ounces in nose and try to make this crazy bird stable.
I already modified my design a bunch in the last couple of hours after dinner... Made the canopy larger, increased motor mount contact (this will be friction fit at this point), standardized fin mounts on ring-wing, shortened front ring-wing mounting fins/wings and added rear ring-wing mounting fins... Here are the parts for a first print run w/ fin templates:
Around 66 grams and bit more than 9 hours to print (w/o fin templates)...
