Dad flew the 66 B model around for several months after the main gear collapsed on landing. Waiting on parts, he had the gear locked down in place and duct taped the gear doors shut and used the plane. If I remember it was about a 8 or 10 MPH reduction. I don't think Cessna ever reported the gear down loss speed. You're not the first person to ask this either. There is a Skymaster out there that was for sale that someone had fixed the gear down. Not sure why but I guess we all have our reasons for doing things.
