I have the CG  VB flying nicely now.   I had to add an ESC (thing RC airplane) and a diode to drop the voltage from 5 to 4.3V and it is flying very nicely now..... I will post schematics soon.

My 9 year old son did that trailer from our iPad :)

He is just loving any toy I 3D  print from an old 70's design!
