Hi,
The thread maybe not for great discussion but as an ex-pilot, lover of aviation and the helicopters I have to create this small MLU window for lonely Canadian WWII-era R-4B.
Only one R-4B was tested by the RCAF during WWII. Paradoxically the first Canadian airmen rescued by the helicopter were rescued not by the lonely RCAF's R-4B but by the American HNS-1 (YR-4B).
In Europe it is impossible to read anything about the Canadian tests of this helicopter. Were there any articles, not to mention books, in Canada dedicated to R-4 in the RCAF service?
Best regards
C.
