She looked pretty solid with both props. Although the high rake seemed smother, the low rake was gettin it. Nice run!👌

That roost you see second prop at 1/2-3/4 in race size oval turn will be more raceable setup. The hull doesn't seem to need a lot lift from real lifting prop. I did similar De-tongue leading tip to all props. Like to see on bigger safer pond.

@jamesatkinson7517 Год назад

The low rake gets up to speed faster if the pond was longer the raked prop would be much faster

Reducing a prop's diameter does not increase the pitch (in inches traveled per revolution), but it does change the pitch ratio (pitch divided by diameter). A 1.7" (43mm) x 1.6 pitch ratio prop reduced to 42mm will result in a 1.645 pitch ratio. Based on temps, I surmise the Octura prop allows the motor to spin up a bit more where the efficiency improves. Increasing a prop's rake actually reduces the lift a prop creates (It tends to "focus" the thrust cone; I sent you a link to look at). Take an Octura 17XX prop and an Octura P-7XX prop of the same diameter: They are essentially the same, except the P prop has more rake, whereas the 17XX has almost no rake. The 17XX has more lift than the P-7XX.

Man, I can build the hell out of a boat because I can just zone out from life. Then I get to the props and get a brain fart because its the opposite of what I get from building them lmao.

@@Buellerwtfman Big B enjoys working on props. I find it tedious, especially with the small props I run. It's a bear to balance small props because the lever arm for an out of balance blade is so small and most balancers have limitations that effect the repeatability of a measurement. Just try to balance a 26mm aluminum prop and you will see what I mean.

@@Dr_Jet Props are for sure next on my list of education, but my 2 year old kid has other plans with my time lmfao

THANKS DR JET.

Great Video Big B. Love the Prop Comparison video's

@slickman1953 10 месяцев назад

I would think the prop wash diferance between the two props would impact the temps.

@mikesullivan5851 Год назад

Awesome video, liking that 642 🤟

@nealstarling5422 Год назад

Great video, with either prop I believe you could win some races with that whole setup, the high rake would handle the chop well. what is the rake of the props you use on your drag boat, the purple Oxidean props ? Thanks Big B 👍

@peteroosterhoff8850 Год назад

Looks like octura rides more stable...

@mikeleahy5283 Год назад

I love the octura in my 30” cats

@jmartin2711 Год назад

Great Vid on the the props with rake angles, thrust cone differences, lifting/non lifting Big B.Good knowledge to know going forward for prop selection, and thanks as always on the vids you do. Quick question , on a side note , could you tell me with the S wake V2 if i should go with 2 Spektrum Pro Basher, smart 11.1v,6800 mah,3s ,120 C Lipos, or a single 22.2v 6800mah,6s,120 pro basher? There is about a 100 gram difference between the total weight of the twin packs versus the single brick.Would appreciate your advice on the selection for the V2 overall.Thanks

@IRONCLADRC Год назад

Personally I like single 6s packs, less hassle, when it comes to charging, plus i have several boats & cars I can use the single 6s pack in. If your other Rc's don't take a single 6s & use twin 3s I'd go with the twins.

Did you ever fill in the lows 3D print on the sponsons on UL? Are you still going to carbon fiber inside of UL? I blew my 2nd stock motor yesterday. Oxidean 2200kv on the way!!

@IRONCLADRC Год назад

Yes sir the cRbonfiber cloth & epoxy motor mount etc is on the way. Now I'll feel comfortable doing speed runs

@TheAWallace1212 Год назад

Big B!! Morning buddy! Great video. I have been using micrometer & measuring tip to tip on my props to get actual diameter. It Changes a bit after balancing. Then I write the actual size in the front side of blade. You can see it in my videos here. Surprised that 642 was faster then the high rake 🤔. I feel my high rakes are faster. I’m really liking the M445 octura on UL19 as basher. Lots for me to learn still! Cheers!!

@VetteWay2Fast Год назад

Can’t wait to see what the high rake does at the speed run spot where u have more room. Got 75 with the stock and ordered the oxi high rake, will be interesting to see if there’s a significant speed difference

@hoodatdare7039 Год назад

GOOD TO KNOW B. I MAY HAVE TO LOOK FOR DIFERENT PROPS FOR MY MADDFLOW.
