facthunter Posted September 4, 2023 Share Posted September 4, 2023 We don't all have exactly the same interest in aspects of aviation. Little that we do is right on the cutting edge and doesn't have to be. Much of the craftmanship of the past leaves what we do now for dead..

facthunter Posted September 4, 2023 Share Posted September 4, 2023 They only do about 1100 R's per Minute and about 10 HP/litre. Lots of castor oil all over the plane and Pilot. High torque and fuel consumption and severe Gyroscopics also. Not put to civil use after WW1. Non rotating Radials were developed subsequently but experienced cooling problems without the "windage' of the motor rotating. Nev 1 1 Link to comment Share on other sites More sharing options...
RFguy Posted September 4, 2023 Share Posted September 4, 2023 I used to ride the ski-doo every morning in skiing years. ROtax powered- Get on the ski-doo, -5deg C- straight to 100% UP the hill out of the valley for 3 minutes 100% from cold. oh boy. never blew up. 2 1 Link to comment Share on other sites More sharing options...

Old Koreelah Posted September 4, 2023 Share Posted September 4, 2023 For a moment there it looked like the prop was rotating the opposite direction to the engine- that might almost cancel the torque effect, like the Honda Gold Wing’s counter-rotating clutch. 1 Link to comment Share on other sites More sharing options...
facthunter Posted September 4, 2023 Share Posted September 4, 2023 it's strobing. The prop is mounted on the crankcase and goes the same speed and direction as the engine does. Later Designs were geared !/2 engine speed. Siemen's Halske and maybe Bentley BR2. That Monosoupape (single valve) is not efficient. It exhausts and pulls in air back through the same port and mixes it with an overly rich mixture from a carburettor at the rear of the motor. It has no throttling as you can hear when the switches to the Magnetos are "blipped" for when you are approaching or taxiing. Nev 1 Link to comment Share on other sites More sharing options...

Looks like its seen some miles, and it is a fully self contained powerhouse. Just turn it on its side, lash it onto the hills hoist air frame and bolt an industrial pedestal fan blade to the crankshaft and you are pure Holbrook vintage; straight into the barbed wire! 🤩 Time to live!!!

facthunter Posted September 7, 2023 Share Posted September 7, 2023 I've done a bit more research on the TOPIC of this thread..The Taiwan made motor. I still think it has good potential. The exhaust port area has more fins than the inlet. It's not that heavy and has Carby, starter and alternator in the best places and it's well priced.

GolfWhiskeyHotel Posted September 7, 2023 Share Posted September 7, 2023 3 point how many litres for 110hp? That's really not good enough. If fact it's not a lot different to a Continental 0-200....... So it's going to burn about the same as the 0-200. That's just sad. Why would a manufacturer bother. All they're doing is diluting the present market. Unless there's some magic property that I have missed or haven't heard of yet. 30 something hp per litre. wow. (in little letters) A postie bike puts out about 75 bhp per litre. They can't do better than that? Back to the Rotax.... 2 1 Link to comment Share on other sites More sharing options...
Thruster88 Posted September 7, 2023 Share Posted September 7, 2023 Pilots don't care about hp per litre, they just want an engine that works. One reason Lycoming and Continental have not been dethroned in their segment. Brake specific fuel consumption only cares a little about hp per litre Brake-specific fuel consumption - Wikipedia EN.WIKIPEDIA.ORG 2 1 Link to comment Share on other sites More sharing options...

They can't do better than that? you forget the difference between DIRECT drive (aircraft) and the postie bike. Check the postie bike power at 3,000rpm!!! Rev the aircraft engine up to 6,000rpm and you will get over 250hp, but not for long. Same for fuel burn: aircooled engines have to use fuel for internal cooling due to the large bores. The weeny little bike piston ccan be cooled by the barrel. You are comparing apples with macademia nuts🙃 1 Link to comment Share on other sites More sharing options...
