CNC Props

[Doby]

I hate balancing and sharpening props....
Never liked it, never will.......
Don't like the fact that the material they are made of can have ill side effects on your health is precautions aren't taken.


This year I ordered everyone of these (except for the 70mm prop):

I like the fact that they are "plug and play" (pretty much). Plus, they are pretty inexpensive.

I use them on everything so far from my P Hydro to my T Cat and T Mono with really good results.

Steve stocks a lot of 2 bladed ones as well. I haven't tried those yet but plan to.

I was talking with Monica at TFL and she commented that TFL makes those props.

She sent me some pics of some of the others (they make lots of other props not pictured)

Just bringing up an alternative that may appeal to some people out there like me (lazy)

Plug and play nice to have a few laying around.

ive got a few now but every time I want to use one they always seem to be in a different state than I am...or are on the bottom of a lake somewhere :) message to self.... remember to get the boat and prop in same place

[kfxguy]

In your opinion, how do they compare to a good s/b prop of equal size and pitch?

[JimClark]

My concern is durability

[ENCORE MAN]

36 inch Sprintcat with twin 1717 motors snapped them like twigs. I have had good luck with them on spec class setups. BG

tried the 45 mm from ose. they bent and almost destroyed 2 batteries. didnt realize they were bent, never hit anything.

Personally I worry about throwing a blade! I think these are better suited for sport setups, 35,000 rpm and below.

Guess I was lucky, tried a 1450 from Zippkits on my JAE 21, didn't like the speed, but I won't do it again now that I have a faster motor--don't want any mishaps.

[Doby]

Run them on my T Cat, T Mono, and several P Boats, each in the 30K range....not one "thrown" blade.

What the heck are you guys running in?

[Livewire121]

If I were to run them, they'd be in my HPR and EKOS. Both of which are spinning in the 45,000 -50,000 rpm range. Another reason why most of my props are stainless steel.

[Doby]

Yeah, well you're a bit nuts with those boats:laugh::hug1:

[Livewire121]

:iagree:

I did a D/T'ing on a x450 CNC prop at the nats and it was perfect for P-offshore, ran really nice. HOR doesn't sell them anymore, should have bought several when I could get them for peanuts.

[Rumdog]

Run a 52mm Cnc prop on a 40" delta MKII. 1717 1600 kv on 6s. No problems, and it rips!

Although I like, & use a few of these props, I spun the drive dog forks off a 4614/3 blade last Sunday at the start of a race.
Afellow club member did the same thing some time ago. But I still like the props.

[Ronbo]

A lot of us here in PNW are starting to use them more and more in scale 1/10th hydros. I just received 46 and 50mm 3 blades. I tried a friends detounged 46mm with 1900kv scorpion and it was very fast and handled well.

[iop65]

there's a rather big difference in the aluminium used to make these props

for instance the ones from tenshock are made from a much harder aluminium then others

[Ronbo]

cant find anything on tenshock props. website doesn't show them. who has them?

[NativePaul]

CNC props are very popular for Naviga racing, and Tenshock are by far the most popular here, well regarded for both their efficiency and strength. I don't use CNC myself as I have a fairly extensive box of worked Octura in the sizes I commonly use, but I have worked a few for good racing buddies and believe them to be just as hard as stock BeCu, certainly a lot harder than the unbranded ebay CNC I was given to do (possibly R2). They are not brittle and will take a little cup just like BeCu, but I have not tried a full on blade twist yet. Due to their lightness and the construction process they are pretty well balanced and can be used straight from the packet, but they can definitely be improved from stock if you are prepared to put the work in to them. They are available from Heath's RC models and AStec Models here in England, I would guess in the states it would be Minicat Racing as I believe Sailr is the sole Tenshock USofA Importer so I don't think OSE are able to get them in.

[ray schrauwen]

Just an FYI. The CNC Aluminum props from R2 Hobbies are junk. THey are thin, cut from 6061 at best and even possibly cnc'd from a cast originally. I ran one for a couple laps once and little dings everywhere from water particulate. Put on a BeCu prop and I can run all day.

I like cnc props but, buyer beware, not are all the same as most here are getting to know.

This is the one I tried. Funny they are 4mm shaft size, the first pair I got that were L&R had 3/16" shaft size, after that whenI ordered a single left turn prop it had the 4mm drive size, that thing was so weak...
