CNC Props

[785boats]

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.

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.

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

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

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.

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...
