Genghis if the Luscombe 8E has a manoeuvring speed of 85mph & I’m almost always under gross weight, Va would be lower still. I just looked over all TEN pages of the “Owner’s Handbook” and was unable to find any such information….. (85mph) what I did find was Vne 145mph, Vno 48-112mph & stall 48mph all speeds are T.I.A.S. If you have a reliable source for more information regarding my aircraft I would be grateful for any help you could provide.
Thanks
