TFL Ariane CF and FG hulls

[785boats]

With the hooks, if the nose is being forced down onto the water by them you may need to move your packs back a bit to get it off the water.

If the rudder is leaning to the side, you should straighten it up. It looks as if the bottom is over to the left a bit? but that could be the perspective of the photo.
The effects of water on all surfaces is a cube of the speed. So, as the speed increases the drag is cubed in relation to the speed. So yes, the faster you go the worse the effects.
The size of the rudder is fine. You need a bit of depth for authority in choppy conditions.

I would either raise the left trim tab or lower the right trim tab if that doesn't fix it. But move the weight (batteries/ESC) to the left a bit first.

I've never heard that a thrust washer would induce torque roll before. Bit if it did, it would be in the other direction anyway. To the left, as a product of friction from the direction that the shaft is spinning.

In the pics, there doesn't seem to be any gap at all between the drive dog & strut. Is that a two part square drive shaft in there? It looks too tight even for that. Could just be the photo.
If it is a welded flex, then there needs to be at least a 3 - 4mm gap there.

All the best.

That is a 1 piece welded flex cable. I just shoved it back in to take the pics. I do leave a gap when running the boat.

There really isn't much in it at all but yes - the rudder is misaligned slightly to the left. Removed the whole assembly last night and cleaned off the glue - and was able to make it better but still a shade off. Looks like a slight manufacturing fault where the mounting screws go through at an odd angle, making the end result different to how you lined things up. Needs re-drilling to correct it I think. Unless someone has a method of bending rudder assembly's slightly to correct such issues?

Hopefully another test in the next few days.

Could the old silicone tube over the end of the stuffing tube to prevent water ingress affect torque roll? Not that it seems to on my other boats. Just.... this one seems very sensitive to it. Anyway...will test with some changes as suggested.

Small update. Torque roll issues solved. Fairly certain it was a bad drive collet. When I spun the prop by hand with everything connected there was a noticeable wobble on the flex before it disappeared into the stuffing tube. Not good. Replacing the collet fixed this, and the boat now runs without a single hint of torque roll. WOT is super stable and I could finally see how nice this hull is to run.

Well there ya go.
All those tuning tips & it came down to that.
Well done. I'll store that one in the memory banks.
But did you change anything else too?

That's awsome, I knew it would probably be something simple. As nice as mine and Paul's Ariane run, I couldn't see how your's could be that bad. I'm glad you got it figured out!

[IRON-PAWW]

Cheers lads! It did seem a little odd - particularly since another member at my club had a very similar setup. Soon as I noticed the issue I had a suspicion it was the cause of the torque roll.

I was able to straighten the rudder somewhat by re-seating it, then just adjusted the trim tabs and strut to as neutral a position as possible. Hardly changed anything there though, so pretty sure the collet was the culprit.

After a year of struggling to get this boat to ride and only topping out at 55mph several times with the most unstable attitude, I finally have her dialed in riding smooth and increased mph by 10 up to 65.1 mph yesterday!!! This is a SEXY Hull and it looks even sexier when she rides nice, I'm so stoked!!!

Well done.
I've never set a boat up for "point & shoot" runs on smooth water. Only ever ovals in choppy water.
I'll have to give it a try some time.

3/16 flex one piece

Hello everyone, new here. I know this thread was started a few years ago, but I was wondering where you guys purchased your 3/16 one piece flex shaft. Also how long is the flex shaft of the Ariane? Maybe I'll look for flex shafts at OSE, or RCBB.

Thanks, Ant

hello!!! just got til Ariane 2 and it is awesome!!

Went ahead and changed the flex shaft from OSE and had a blast on 6s. The stability is amazing... love it
had to give a bit positive to the strut and raised the trim tabs also and got some wind under it, was having so much fun that forgot to lube the flex after around 8 runs and it gave out...
got her running 55mph on an octura x442 but want to move up to a x445, can anyone tell me what props you guys use?
best regards,
Eric
