I guess your post implies it, but I imagine a vertical shaft engine that was meant to swing a heavy steel lawn mower blade might be converted to horizontal and handle a lawn mower blade just fine. I wonder if some of the horizontal shaft engines use the same bearings?
Using two of these means that two 4 foot props at 3600 rpm are like one 5.6 foot prop at 2,556 rpm. Presumably, that means no redrive necessary. I'm also guessing that the little motors will stand up to correspondingly smaller props better than the big motors will. Whether that's good enough on a horizontal shaft motor, I don't know. Plus there are always the single engine issues to deal with unless it's a push me-pull you configuration.
The rigging sketch for the "V" Tail sniegolot is mind blowing.
Man oh man this guy was prolific. never seen anything about him before. Is anything around in English? Especially but not limited to his propeller designing and carving? He has some of the nicest looking propellers!
Unfortunately, the designer didn't fly the plane at the show, and said he hadn't for awhile. If the designer and several others were flying around putting on hours, I'd be much more interested. But it seems to me very much an unproven design. Apologies if untrue, and very happy to be corrected......
You should check it out this guy was cool.
Personally I like the other one, the Cirrus. I wonder if something like that could find favour as a low powered US ultralight? I really like the Schwimmwagen that shows up in some of the pics too. I sure hope he didn't scavenge the Cirrus' VW engine from it.
If it's actually practical to convert vertical to horizontal, that might be more comfortable, but it's my guess there are horizontal engines someplace that use the same bearings as vertical. Anything like this should probably be tested on the ground for a while. Airboat? Prop powered kart?
I wonder what, if any, single engine testing has been done with the Home Despot plane?
Yes, that's true. However, with two engines, the chance of losing one of them is almost doubled. So it's a problem if it won't stay in the air on one. Also a problem if rudder can't keep it straight with one. And, of course, a bit more pilot skill is demanded. I think it could be a very big problem if one engine goes and:
-there's no accurate airspeed measurement or
-Vmc hasn't been determined or
-the pilot doesn't know Vmc
-the pilot is inexperienced and/or hasn't practiced engine out flying
