Re: Airboat in Hong Kong movie 1986

It's very strange. I can play it normally. I visit youtube through VPN in NY, otherwise Chinese Internet Greatwall will stop me.
I upload the video to Vimeo also. Enjoy it.

Re: Sanshandaobojue's airboat building 2017

Ignore the small bits of wisdom you are given from members of this site at your own detriment. You will not achieve 8lbs of thrust per hp in an Airboat application once you get beyond extremely low powered designs, such as yours. 10hp, 20hp is 5 to 10% of the power you need to use an Airboat for an...

Hi, I am perpare airboat with bigger engine.
Is your boat have a clutch between the engine and gear box? I think if without clutch maybe the engine is difficult to start, the startmotor will damage.
Usually the airplane have clutch in the gearbox.

Re: Sanshandaobojue's airboat building 2017

That means if I use 100hp, hopely I can get thrust force 400kgf=890lbs. You will not see anything close to that kind of performance just by adding 90hp and using your same propeller. You would do well to read up on propeller theory. In particular pay attention to disc loading. Before you build anot...

Very good job Benjamin, just a thought, but I think the transom should have been a little wider. It would help it get on a plane and make it more stable.
