Active canard

[TotalPackage]

Your knowledge is not the best. First, nobody said anything about turbine-powered hydros. Second, it was Jim Lucero, not "Bob". (Jim was alive in April 2009, when did he become "late"?) Joe Taggart used an adjustable front canard surface on his limitied hydros in the 1970s IIRC. The 1980 turbine Pay-n-Pak did not use an adjustable canard surface.





Mr Taggart was also the first to put a vertical tail on a hydro in the 1940s (the Tomyann I believe). He did it not to provide stability, but so that other racers could see his boat through his roostertail (which was a lot smaller back in the 50s than they are today).

Mr. Fluid I stand corrected on everything I said . I also appreciate appreciate the history lesson on Unlimited Hydoplanes. This is off topic . You hold some current records in the boats right now correct? Could you tell me what they are and your speeds?Not trying to be funny just curious?

OMG !

Can ya see the sideburns on those geezers ?

If I had whiskers like that there'd be an NRA bounty on my head !

If you are looking at 5th in from the left then he either has a beard or an impressive set of lamb chops.
The guy on the boat has smaller sidies than me !!

To stay on topic.
I have read a lot about active canards and active trim control on RC boats. I have all respect to he who pushes the boundary and learns more.

Long sidies means less shaving foam too.

Had to laugh at the record book. The N1 Hydro record is 3 MPH faster than the P Hydro record I set 12 or 13 years ago.

Wayne it seems to me if a gyro can deal with the sudden and ever changing attitude of a big 3d chopper it can deal with a blowover.Sorry guys after some thinking I just dont buy it.

Then try it and when you got it running go rewrite the record books!

After the GFC even the mile is a bit stretched.. ,, making us work harder to beat previous markers.
Chance is high the course is longer than before....

good way to burn out a high response servo is to grab the tail of a 3D and shake like crap ... welcome to the nose of a fast boat.

Factors you should consider.
Speed of boat proportional to speed of servo response .. and inversely to deployment end point.
No activation through cornering is a thought.. else that nose high corner may induce a canard nose under ...

grab one a $25 gyro from HC and try ...grab a pic, and play !

For me its not about rewriting record books, or a colorful discussion.I believe in talking to others, as well as my own thinking that it is possible.These folk may have been unsucessful and so may I but that doesnt mean its impossible. Secondly fundamentally speaking sounds like were talking to different things from the start. As you remember the first thing said was "theres a big difference in real boat and rc boats" yeah it sure is. Most of us run flexshaft.
So we can control our ride attitude more so with strut angle and what have you. Next It was said that the canards where desingned to help with attitude. Does this mean that the failed attempt of the others tried to mimmick the canards on the real boats in the same way?If so ,this is not my quest. I simply want a canard that puts force down in the right turns to try to keep the boat flat in the turns and a canard that if it sees an angle above a preset value it will diploy flaps up to a preset value to bring boat back down to a preset value and then start all over again. If you tried to control the action with say a surface 4 channel (which I have one) thats how youd get into trouble because youd inadvertantly move the flaps and induce a blow over instead of prevent one. Anyway.......

less talk, more action !

I hear ya wayne. Sorry for the typos.

typos dont worry me.
What really bugs me is the forum spell checks Australian into American. !!

come back in a week and show what you've done.

At least with this project there's a much better chance of success vs. making a 200A ESC from parts with no prior knowledge. It'll cost him a few high-speed servos and gyros but he'll be able to run the boat the whole time.

Except when it's upside down, of course :)

I've seen pics of the real canards move and they are very fast, almost fluttering. One issue I see is that if the boat starts to lift off and the canard tries to adjust it may adjust too far and dive the boat.

I think I might prefer a manual adjust where I could flatten the boat into the wind and raise it with the wind. Lift the bow for cornering (like the F1 boats do) and flatten it for straights.

Yeah, whatever happened to that project? Lots and lots and lots and lots of talk = zero action. Just another in a ceaseless list of "colorful discussions"......
