In the air the C285 (because it is a 200 series Cessna on 185 gear, hence the 285) fly’s just like any other C210 I have ever flown, even all the way down through final approach. Landing is the same as a C185. “Oh, but what about that slant tail” vs. Straight, "it is all about looks". Some people like the straight tail look on tail draggers because that is what we are used to. Maybe? I have always liked the 185 look! But in a 30 knot crosswind neither straight or slant is any fun (I've done it). You better be on your toes no matter what you are in. Weather veining is all about square inches of side area. A 30 knot wind exerts a set force per square inch, it does not care about slant or straight. They are actually pretty close. Being fair, the slant is slightly further aft but the 185 fuselage is taller/thicker. I can’t tell the difference, and it sure isn’t worth changing the tail over. Did I mention that the C210 is 4 inches wider than the 185, and with the leveled baggage floor, like the 206, it makes for a lot of room. With an entry door on “both sides” and fair sized baggage door, I have never had trouble getting stuff in it. Doors hinged at the top, like used on drop zone planes would be perfect. And 206 doors on the R/H side could happen with the right amount of cash. One thing at a time though.
The plane is licensed in experimental “research and development” and I have been working on getting a onetime field approval/STC for quite some time. My first thought was to use the heavy duty PPonk gear fittings. No reason to reinvent the wheel. They even sent me a set (good people) but they did not work unfortunately. The fwd part of the fitting was two inches above the floor board. Machined fittings, built up gear box, and C185 main gear and year later, she was on her own legs.
My 285, as I call it, has barely been used, with less than 2500 hours total time. I’ve put 500 of those on it. Hanger kept it’s whole life, it’s been pampered and polished. And many C210s have been upgraded over the years with primo avionics packages by owners that only want the best for their baby. Mine was upgraded with a full stack of King silver crown radios (old school now) but better than the old Cessna radios. The Cessna 185 has been the work horse of the bush industry for more than half a century. Millions of hours have been flown in the C185 they are one tough plane. They have proven themselves in the bush no doubt. The Cessna 210 on the other hand, has been, and still is, an asphalt only, executive cruiser. Most have never even seen a dirt runway. Reckon you could find a C185 with less than 5000 hours on it? The actual mod is a bit more that gear fittings. my biggest struggle was with the manual flaps/AKA Johnson bar. but consider belly skins, tail stinger, flight control cables, header tanks, ect.
