Simon's Canard.

I think it just takes the right neutral aerodynamics combination. I think once you get there, you'll think they're easy. The main difference is the rigger has less surface area to overcome and thus, less margin for error. You've got both on plane and running well. Now take it one step further!

Edit: I mean that riggers allow for a larger margin for error.

I know it doesn't scale, but there may be some tricks on the underside of an '81 Circus Circus if you can find pictures.

At the moment I have trouble keeping the rear down on this one.

You should be able to wet down the rear sponsons to settle it down. Also have no aerodynamic lift in the tunnel.

Thanks Randy. I do like the Circus Canard !
The rear of mine is currently a lot more alive than the previous shape and that is my fault as it was rebuilt wrong after its spectacular crash.

I now have a 432 running at the sponson bottom line and it still blows out a little on the straights. I will repower it with a 8S 4400kv can and run a bigger prop like a 435 and see how it goes.

Prior to the crash it was happy with the 5000kv (Ben's old beast) motor and a 632 but now it needs more attention than a teenager.

I'll get this hull sorted again......I've done it before

LOL, it looks like you said 8s on a 4400kv motor! I know now that you mean an 8S motor. That was a good motor and I'm glad it has done well for you.

That IS still a great motor (the 7S) and may go back in if all works well with the bigger prop

I need to get you some of that fancy oil I used with it. I'll work on that.

8S on 4400kv?!?! I know that's not true but that would give 130k rpm unloaded!! fun stuff.

No no no 8S is the motor size, 50mm long 540 8turn, short.
I run these on 2S lipo or 3 for a real giggle

[Boaterguy]

I know what you meant, I just wanted to calc it as a joke, you should try it though!!

I had this one out again on the pond this morning and got a few good runs but it was hard as there was a whole new flock of swans on the water, for 3 years I have never seen this many swans in my little corner quarry.
As I mentioned above I have had a few problems as the rear of this hull now has a greater vertical movement as a result of the increased lift from the rigger sponsons than the last setup, and I had issues with the 32mm prop blowing out due to this.
Well I threw a 35mm prop on with a lower kv motor to give me an overall similar calculated speed.
It works ! We all know there is a sweet spot for a prop and I am close even after one run.
The sponsons still create lift as speed increases therefore the strut is lifted but it all seems like it is coming together again, this was my favourite hull and may be again soon !!

great to hear it Simon.

how are the turns?

[Simon.O.]

great to hear it Simon.

how are the turns?

Still very wide and drifty at speed but with throttle control I can keep it on the plane and turn in about a 10'radius circle.
