my new carbon fiber cheetah!

This is the gap it has

Give it a bit more

Get rid of that prop it's a waste of time for you to test with it.
The difference from a carbon prop to a good S&B brass prop is night and day.
Or get CNC aluminum at minimum
Start with a 447/3 blade or a 450/2.
I think you'll be wanting a 450/3 it will spin any of these no problem.
Get 1 that's sharpened and balanced from OSE.

I have a worked m645 and a cnc 45mm prop right now. I didnt try them. I should have. Just didnt have time. Im going to order a few more cnc props from ose tonight. Try again next weekend

Its just hanging off my shelf. It sits perfectly level on my glass tablr.

Scott is referring to the gap between the drive dog and strut.

How is the strut for being square with the hull? You can check this by placing a 3/16 brass tube in place of the prop shaft so it sticks way out the stern. If it is out by a bit that will track the boat. By this token you can shim the strut to straighten the tracking. Make sense?

Here is a REAL GOOD reference page for starting out with a hull. Chek near the bottom of page for 'setting up'. I know it says mono but the rules apply.

Gues I should post the page. http://www.modelpowerboat.com/conten...ude&styleid=4w

Yes gap is what i was refering to, drivedog to strut. More.

Gotcha. Weve been text back and forth all evening (scott and I) and figured out I have the wrong strut on the boat. The one I have is too short. I did set a little more gap on the prop shaft too. Ill also check the alignment like you stated. I just want to let you guess know, I really appreciate all the help you are giving me. I think next outing will fair much better.

[tiqueman]

Not necessarily wrong... just room for improvement.

Two more days left. Finished up a couple props for this weekend and ordered a few cnc ones and an octura 3 blade. Nor sure if the Octura will be here in time but we shall see. I also bought a skeg style strut to try out. Cant wait!

[kfxguy]

I got my skeg strut in today. Its set farther back than the strut I have now. At first I was just throwing the towel in an not gonna fool with it. Then someone talked me into it. So I need my stuffing tube to be longer and my flex shaft to be longer. Well I have a longer flex but I didn't really want to solder an extension on because I thought it would look like poo. Then it hit me. My geico has this nifty little cone in the front of the strut. I grabbed it out my box. Close but not close enough. Guess it was time to get creative now. I ended up making one on my lathe. It added some length to it to help support the shaft and I cut two grooves for orings to seal it. First time I cut a taper on a manual lathe. It was pretty tricky.


Heres the setback difference



Here's the geico one



Here's the one I made

And here it is together. Ill finish it up tomorrow.

Sweet dude,
I was thinking the same thing, make your own! Its good to see people on here with fabrications skilz.

On props, with that big ass motor, you can push a lot of pitch. As i learned from Fluid, a 50 mm prop will prop-walk a lot with this hull, so the only way to go faster is more pitch.
know that TP USA sells CNC props with a 1.6 pitch. They do need balancing though, or at least the ones I have from them.
What props are you getting?

Thanks! I have a octura x447/3 on the way and a cnc 45mm 1.9 pitch came in yestrrday. I also have a worked m445.

[larryrose11]

cnc 45mm 1.9 pitch? From where? Link?
