Do you know those propellers? They are belanced just need to be sharpened
A set of 42mm DD for twin looks great and not very expensive

how wil the aluminum hold up with the rpm`s ?

just have notised that when i run my mhz aluminum prop (29 1,4) on my micro drifter it is noticeable slower then when it run it with a octura 427.

I don' t think Prather S propellers work fine, No advice about Hopf/Tenshock props?

[Brushless55]

They look sweet!

[Alfa Spirit]

Nobody use those propellers? 4 size are available 38mm 40mm 42mm and 45mm diameter, pitch = 1,4

I have been wondering about these also. My plan was to rig em up with a .188 hole so I could actually use them first......

[Alfa Spirit]

2 versions are available M4 and DD 3/16"

[blackcat26]

Cool. I was wondering if they would deform under high rpms also

2 versions are available M4 and DD 3/16"

Alfa, could you translate for me, which ones are for the 3/16? Couldn't figure it out.

I have two in my cart... As for deformation, I think there will be much less force on each prop when run in twin set ups. I don't foresee much deformation and am really tempted to pull the trigger - my twin Triton has that look, "what, I don't deserve em?"

Is the one that says Drive Dog the correct specification for 3/16?

Drive Dog

The shipping looks like it is 25 euro?

[Gerwin Brommer]

Yep, DD = 3/16 th
Shipping is 25 euro

BUT : why on earth is the prop balanced but NOT sharpened ??
if you sharpen in yourself, the balance is gone !

You can choose the language

I put an order for 2 props 42mm one right + one left = 85US$

exactly what Gerwin said... CNC props should be sharpened as well... they are made so you can plug n play.
I bought some from a local vendor which would be better in your case and cheaper as well...
