I recently purchases the Fairchild C-119, available here: https://store.flightsim.com/product/just-flight-aeroplane-heaven-fairchild-c-119f-the-flying-boxcar/
After printing and binding the .pdf manual to use for reference, I went through the cold start procedures carefully, but with no luck. I've noticed some discrepancies between the manual's pictures and identification of switched and what I see in the VC, but I doubt that is my problem. Probably 'pilot error' in my case.
If you use this aircraft, can you start the engines from cold?
