OK no problem, I'll be sure we get some this weekend. Man it really must suck to have frozen lakes for that long of a time! I can't help myself

[Monica Smith]

I notice that Ron most speak slang English, I have no idea at it at all!

Had to laugh Monica, sorry but thats so funny

[Monica Smith]

Well, Andy, Should I find a cave to hide myself? I am so ashamed!
Maybe it is time to find a teacher teach me Slang English, I think.

[sampit]

Monica thats even more funny
Should I find a cave to hide myself that had me rolling aroung the floor with laughter, tears running down my face!
your English is fine,we all know what you mean, no need for a teacher.

looking back, what English slang do you mean with Ron?

[Doby]

Ron doesn't speak "English", he speaks "American"

Fortunately, sharing a common border allows me to figure out most of what he's saying

Monica, I thought you and I were doing so well with our "slang" lessons. I'll have to try better when we e-mail and skype.

I think it was a a de-tongued Y547 its the one 785 recomended

ok here is the American interptation de-tounged= a propeller that has the leading edge cut off
785= an aussie that has recommended a prop

hope this helps even u guys in the great white north should have figured this one out lol

No Videos today Doby, too windy and rough for testing hydros. We damn near had white caps on the lake today!

Ron.
I'm glad that you & flapraptor like the Y547 as much as I do. It's got just the right amount of lift with a 2200kv motor to get the tail up with the COG back that far. I also run just a smidge of negative in the strut.
As Ray suggested, I'd also like to see the profile of the de-tonguing that Daz worked into the prop too. Unless it's a national security thing. Mine is what I'd call 2/3 de-tongued. Not fully de-tongued.

Cheers.
Paul.

Paul, I got this prop and want to try, but I don't think mine is de-tongued, what are the negatives w/o this feature?

[785boats]

No real negatives but it will load up the motor a bit more. Therefore a slightly higher current draw & possibly increased temps. It may also have slightly more lift which may be a good thing. Just means you might not need any negative angle on the strut.
I never tried it as a stock prop so I can't really say.
But I have seen boats run bigger & higher pitched props, than what was thought to be the optimum, resulting in faster boats, with less heat on the electrics, & more capacity left in the pack after the race, because the boat just "FLIES" better.
Just give it a try, & monitor the temps & battery usage.

And these results were with de-tongued props ?
thanks

[785boats]

Some were de tongued & some weren't.
One guy, on a test day, after running a setup & prop that was thought to be the optimum for heat & battery usage in the races for the previous few meetings, tried a bigger prop. Temps were down slightly, & a bit more left in the pack.. And the boat was faster. Other variables could obviously come into play. But the boat was just 'flying' better so the drag factor was reduced. Results were repeated on a couple of boats.

Paul, as usual, thank you very much!!
