Working front wings

[ozbryan]

I want to make the front wings on my scale build work. Ive seen a set up before where they ran off the steering servo.

Anyone have suggestions and photos of set ups?

Need help.

Use a Gyro off a heli.

then setup the parameters so when the hull is at a desired angle the gyro will control the servo and tilt the canard wing to counteract with tilting the front wing as needed to help try to stop a blow over.

The best Gyros on the market for this app would be a Futaba 611 nice and cheap, ezzy to program.

I believe Tom Kelly (posts here on IW) has a working canard on his '10 Peters & May.

Is anybody actually successfully racing using gyro controlled flaps? I just can't see an auto gyro being able to react quick enough given the margin between being light and blowing over can be incredibly narrow, the change in boat angle seems bugger all.

Prefer to just set and forget myself, don't even use a servo.

I think if we can react fast enough (some times) to prevent a blow over on a scale, I think a gyro would be pretty good after watching how the gyros work on helicopters. Once the attitude of the hull meets a certain angle, the front canard would go to an extreme angle quickly to force the nose down, however, it would have to overcome the prop thrust from pushing the rear end under the nose. Not sure if that would be possible. I think gyro would have to override the throttle as well (if possible)

Definitely an interesting concept. Too much technology for me to go wrong.

When the time comes, it may be on the list to build into the next scale. But for now, I still enjoy watching my Miss Madison live on the edge.

I have had several working front wings but none with a gyro. The newer style hulls with the big wing in the front are difficult to maintain. In racing conditions when you jump that big wake the water can rip the the thing off if it is not REALLY strong. (ask me how i know). My 1/8 scale tony the tiger and my 1/6 scale lobster boat both have wings connected to the rudder. One with a second servo. Turn right and the wing lifts the boat and left shoves it down so you dont roll trying to miss a dead boat.

Have you have found that it has made difference to the handling of your hull?

Or should i just not bother.

put a lump lead in the front and invest the money saved into a slab of Jack Daniels,Jim Beam etc.

 

[ozbryan]

Hahaha scott i like the way you think!

I've seen boats that had operational canard flaps that didn't handle any better than one with flaps that had to be adjusted on the beach. As someone has already said, it's all in the set up. On windy days, I just raised the flaps on my Elam's canard and ran it.

I don't notice it as much in the turned but it sure does help when I have to turn left!

So this is how my set up works, I just use a servo mixed with the rudder. When the boat is running straight down the shoot, my canards are up, and when I go into the corner they drop flat. There is also a dial mixed on my M12 so I can adjust them up or down depending on the wind. I've tested my boat with the canards up and down in the corners, and its faster with them down. My boat is pretty fast in the corners. There is a square tube, glued in the wing one size bigger then square on the shaft, they lock in together when the shaft is slid through the wing. Photos of my set up.

Have you run your boat with the canards down on the straights Pat? If so did you notice any difference in speed etc?

 

[Pat Bristol]

It's a fine balance on my boat, I run 2 degrees angle in my strut and about 20% canard wing on the straights. If I want to run zero canard wing and not blow over, I have to set my strut angle to 6 degrees, doing this pushes the nose of the boat down too much, scrubs straight line and corner speed. I prefer to balance my boats as I build them and trim the ride with the tools I have on the boat, wings, strut and prop. This boat only has 1oz of lead in the left sponson, for side to side balance.

Every boat is different and takes some time to get the setup correct, it seems like I'm always working on it.

 

[ozbryan]

Pat thanks very much for the photos and info!

Beautiful boat! Im building the 92 tide.

 

[ozbryan]

Pat do you run twin tanks? Im considening only running one tank on the turn fin side.

 

[Wayne Johnstone]

Thanks for the info Pat, really appreciated.

 

[Pat Bristol]

Thanks, I run a 14oz tank on the left side and a 2oz header tank on the right.

That's a good setup and a good hull type for that kind of setup. If you hit a hard wake you may only bend the rod a little. I didn't put that setup in my 6 scale bubble bud but I may have too later on. We will find out this weekend at evansville.

Pretty sure gyro is not allowed in IMPBA
