Speaking of Props

[robby76]

i didn't want to hi-jack SJFE thread on "Excellent Read" where it got down to CNC props. so i'll start this one and if you are using any of these CNC props, we all can learn from the application being used in.

The first production run is made from 7075-T6. The strength is equal to a standard cast BeCu alloy prop.
"The steel props will follow after we have had some good testing time with the
aluminum. The 7075-T6 Alloy is almost 3 times stronger than normal cast aluminum props so they will hold up for most applications."
5083 3 blade Dia. = 50mm Pitch=83mm.
The 47mm (dia.) x 73mm (pitch) prop. The pitch is 2.9" which is slightly bigger then an x447 and an x646.
The 4569/3 Dia.=45mm Pitch=69mm T.E. is at 3.4"
The 3857 4 blade. Yep, 4 blades! Dia. is 38mm and average pitch is 2.25" with the T.E. at 2.6" With four blades this prop will hook up well without needing excessive power robbing cup. This prop should work well on sport hydros, vees and Cats too.
A 3657 4 blade and a 3861 4 blade.
3874 4 blade. With a 1.9 pitch/dia.ratio and 15 degrees of rake it may have some interesting results for a .21 rigger.The pitch is about like a 1450 with 3.2" cup. The diameter is small but with 4 blades
a 3457 4 blade. I designed it for the .15/.18 RTR hydro. This one has a 3/16" bore.

here are pictures. Keep In Mind they are offered in L&R.

The four blade unit's are awesome. Can't wait to pick up some.

Even if the 4 blade doesnt work well on a particular hull, it will look very slick sitting on a display boat!!!

Damn skippy!!!!!!!!!

man, some nice looking props

[robby76]

for now they are $30.

[Ub Hauled]

$35 shipped, right?

[z400]

i havent bought any props from them yet, only a pipe


but does anyone know if you can send in a prop and have them balance/sharpen/polish it for you?


or course the person would send money.

but as soon as i find the right prop, or maybe 2 or 3 decent props, i would like to get them balanced and such instead of buying another brand new prop that already has the work done to it

I've ordered a few props from them and they do INCREDIBLE work. Their new props look great.

As far as working a prop you send them...shoot'em an email. [email protected]. They communicate very well.
