Re: Noise - Anything Quieter than a Vanguard Hovercraft?

Chris, you might have to find a new place to hover, or pick a better time of day when most people are not along the river. Fishermen can get upset for just talking too loud, so the hovercraft noise might not be the real problem. Everyone seems to think that they own the resource, when it is actually...

Re: Vanguard 18 HP V-Twin Skips

1. It could be a carb issue, clean it out and calibrate it. 2. There's a black wire connecting the two coils. This is the kill wire. It has diodes in it to keep the coils from back feeding into each other. If one of the diodes is bad, it will do funny stuff like this. Disconnect the wire from the co...

Re: Reversible prop

If it can be done on a model airplane,
it can be scaled up to a hovercraft.

Re: Reversible prop

I agree with Bryan, that reverse thrust has its limitations.
I also believe that it has its usefulness in some situations.

Re: Reversible prop

Some people aren't so easily persuaded. https://www.youtube.com/watch?v=It9h86EKyJM I regularly operate on narrow rivers with dams, etc.) but there may well be situations where reverse might be useful (trailer being one). You need to weigh up any advantages against the disadvantage of adding a compl...

Re: Reversible prop

John, if you are running on lakes all your life, then a reverser would be of little use. However, if you are running up and down fast flowing, narrow rivers or streams, then a reverser could be very useful in controlling your descent. Also, if you were navigating tall grass or shrubs in a swamp area...

Re: Reversible prop

I'm also in Alberta, (just outside...

Re: Reversible prop

On the topic of reversing a hovercraft, has anyone ever considered a parachute thrust reverser?
I work in the aerospace industry and have seen plenty of aircraft reversers, so why not a fabric one?

Re: Reversible prop

Ray, I believe the problem starts with the mass of your prop and pulley. Look at the following video. The alternator and engine fight each other. https://www.youtube.com/watch?v=MTGD8MZf-oM Specialized decoupling pulleys can alleviate the issue. The same problem occurs when you have a large pulley a...
