New abc props

[kfxguy]

Have any of you guys noticed there's some new props popping up in the ose store? I've been trying a few and have had really good results. I have a new chart but I've got to figure out how to post it. Not all are available just yet.

[kfxguy]

Here's the charts

Oh yes. The new props are very good.

1817-17-45 is my new go to prop for P-ltd hydro. The 1815-17-45 R is hard to beat on a 1/10 scale.

Thanks for posting the Chart! Now I can see what number to order and try out!

No problem. If anyone doesn't know how the numbering system works just let me know and I'll help you as much as I can. It's a but different than octura but still easy to understand.

Is this something custom? It's not on the chart.

I like how the chart lists Diameter in inches and mm. I take it that a 1.7" (43.2mm) x 1.4" pitch to be similar to an Octura 443?

Thanks terry for pointing that out. I accidentally left that one off. Fixed.

Sort of. The pitch on the abc props is (from what I was told) more accurate than the octura pitch. Although because they seem to be more efficient they don't load the motor any harder but will be fast (in all of my tests anyway).

And the increased 'rake' negates the effects of transom lift as 'rake' promotes bow lift.
Just thought I would add this Travis.

[Jamey]

What are the differences for cleaver versus chopper?

[dasboata]

probable meant 1815/17-45 R I have them in stock thanks chris

[dasboata]

What are the differences for cleaver versus chopper?

cleavers have point ears and the choppers have big round ears there are other differences also !!!

[Jamey]

lol Yeah I understand the differences in the look, just not sure how the use of each. In regular boats cleavers usually have a lot of stern lift and almost always are used in very high performance applications. So in a sport 32" mono deep-vee would I consider both cleaver and chopper or only cleaver?

[dasboata]

Absolutely try both !

So we don't scare anyone away I wanted to point out that what you stated is correct but.....

I've run these new props on two monos and one cat and what I've experienced is a more stable and smoother running boat in all three. I didn't really notice any added lift. I didn't have to change my strut settings either if I went with close to the same size abc vs octura I was previously running. So people don't be scared of the "lift" mentioned. I know sometimes props with lift can throw the whole time of the boat off.

I also want to point out that these new castings are frigging nice! Most every one I've checked out the bag was balanced or very close to it. They new method he's using makes a much nicer prop. Here's some that are untouched to give you an idea....

[srislash]

Yeah, I wasn't trying to scare anyone away. Just the old props did have a bit much transom lift and cavitation compared to these newbs(at least the 1.6and 1.8's). I like my 1815's so far. They really bite in guys.

I might have to give this one a try in mine

[raptor347]

Picked up 3 mph and dropped 7 amps. Better than that was how smooth the boat was.

Very nice man!
I think I am running a M445 at the moment

[kfxguy]

I picked up 6mph and dropped a few amps. Can't remember exactly the amount and yes was much smoother.


Here's the m645 first to compare....

[kfxguy]

Here's the 1815. To me it even sounds different in the video. There was no changes except prop. Both on 6s.

That is perfect water! Just a little ripple is nice. It seems that it is time to break-out some prop pliers and add just a little cup to the tips. Just be aware that this will reduce the lift.

Is the strut neutral? It looks like there may be just a slight positive based on ride attitude. Have you considered dropping the strut by just a little less than 1/32"? It seems to still be accelerating halfway through the straight and it looks to be airing out a tad more. This will also help when you have glass water.

I'd check the strut for neutral first. If it is, then drop the strut. Remember to only test one thing at a time.

How are your motor temps on the new prop?

This is looking good and runs smooth. This is now within 10 MPH of the IMPBA record, which is very respectable. :thumbup1: That is the beauty of taking advantage of good conditions. Unfortunately, that is not always the case on the record events. :ohmy:

Very knowledgeable! Yes it had some positive. Had. This boat is the one that sank. I'm building another one that should be even faster. This was maybe its third time out. It still had a bit left in it too. It's actually been 97.5mph and so has the one before this one....with an m645 prop.....so it would have gone faster. But on the next one I'm going to make sure the strut is level. I've got some more tricks up my sleeve.

The temps didn't seems to change but I did have a cooling system issue. I baty had any water flow because I was trying to be stingy with the inlet hole size for less drag. I did open it up some before my last run but since the boat never made it back in....I couldn't really tell you if it helped or not. Lol

[Meniscus]

In many cases, 6 series props can put a lot of load on components as a result of blade area and several other factors. If you can turn them, then they are fast. Switching props can certainly unload the motor some more and allow for more headroom. We're looking forward to seeing where you go next!

[dmitry100]

Meniscus: What is that Nano-Oil you have mentioned in your signature? Do you use it as a primary flex lube?

[dmitry100]

Kfxguy: Have you had any luck with those ABC 3 blade props?

[kfxguy]

Kfxguy: Have you had any luck with those ABC 3 blade props?


I have some but haven't tried them yet.

[Meniscus]

I use Nano Oil's grease for drivelines. You can use most any high temp, lithium grease. The one that Nano Oil has doesn't break down as quickly. Consequently, it doesn't get sticky like others do.

I also use their oil on motors. It is the best oil I have found for this application. It is pricey, but I find I dont use very much and it lasts for a long time.

[dmitry100]

Meniscus: Have you tried anything like the Ceramic grease like the kind MBP has?

[Meniscus]

Without hijacking this thread, I have tried many, many different types of grease and many types of oil for bearings. This includes blends as well.

[dmitry100]

Meniscus: Any noticeable speed increases when using Nano oil over things like blue grease in the drivelines? Kfxguy mentioned using duralube before but I'm not sure how he uses it or if he blends it with grease to thicken it a bit....

[kfxguy]

I don't remember ever saying I use duralube. I use motor oil and graphite powder or proboat grease.

[dmitry100]

kfxguy: Oh ok, my bad then. It might of been Srislash that made mention of it.

[Meniscus]

I cannot and will not make any claims with regards to speed increases when using Nano-Oil. However, I can say that everything feels more smooth and the grease in particular does not become sticky, unlike many others I have had the opportunity to run in the past.

This being said, if you are seeking additional input, I would recommend starting a new thread specifically for this topic and garner comments from others concerning what they use. Meanwhile, it will allow this thread to return to the original topic. :thumbup1:

Guilty I use Dura lube and Lucas Marine Greece

[Brushless55]

is this better than just using grease ?

[srislash]

It totally freed things up Todd. Grease like normal then a couple drops of the oil in the top of the flex.

[dmitry100]

srislash: Would it be better to maybe just blend the 2 together 50/50 ? Thats what I've been doing lately and it seems to have a noticeable difference... or I could just be seeing things.

Which ever works Dmitry. I will tell you that I forgot to add the oil awhile back and my speed went down to 92 from 101 with the mixture.

So you lost 9mph from not adding oil to the grease?

[srislash]

Yup

[dmitry100]

srislash: Oh wow, thats pretty significant difference then. How often should I be regreasing the entire driveline? Seems like alot of work to do it after every run. Perhaps I should just add some oil from the grease fitting of the STS tube seal instead of regreasing it all every time.

The gas guys claim that perhaps a thicker gear oil can be used in that exact way. I usually re-grease after my day out but since my 'clicks' and bearings I don't pull it apart to often. BUT, it did take a bit to seal the assembly to that point where water does not contaminate the oil/grease mixture. Until that point daily greasing should be done. Bear in mind I am only referring to my Fantasm, all my other boats still get the end of day cleaning/degreasing.
