Props

[NitroVal]

Just got some x442 props from OSE. First of thanks to them for some super fast shipping. I ordered them Friday night and got them today. Im gonna try these tomorrow and see how they do. I also got some x450 3 bladers which Im guessing are way to big. I dont why I ordered them, must have miscalculated something..
Any thoughts on teh 442s?

You should be able to run a x642 prop on this boat without any problems..

[RCprince]

The boat might torque to one side, 642 doesn't have a CR prop.

[NitroVal]

Yea, Im finding out the CR props are hard to come by. The x442 is the smallest CR prop I could find

[tth]

ABC , Graupner K-series, and CMDI are a few more.

ABC props are really nice

[Flying Scotsman]

Have you balanced and sharpened those props? If not, do not run them!!! A 3 blade prop takes me at least 2 hours to balance and sharpen

My x442s are balanced and sharpened. I think if I find a three blade that will work, I will have someone else balance it.

I have a set of 36mm venom pro machined aluminum props if anybody wants for $50 shipped. Paid 80 bucks with shipping. Used once.

Didn't like them ??

they work great, but I wanted to run a smaller prop for 4s so I bought a pair of 32mm's

I shaped some x442 octura props for my friend chris's king and they came out great. No over heating. and stable as a mo-fo. So much faster then those little 36 mm.

stock king of shaves brushless. 7.4 4000 30c for now,11.1 4000 on there way. but if i were to build one from scratch 2 x aquacraft 60 amp and gold motor to match....

[forescott]

442's might be fine on 2s but 3s is a different story. I ran 442's on my ekos on venom 3s 11.1v 5400mah lipos and the motors were blazing hot! That is why I went to 36mm props. And even then I have lost one motor on 3s.

[NitroVal]

I ran 442 on 3S for a while and they will work, but you definitely have to watch the temps. I usually only did one speed pass, then on the return run at about 1/2 power to cool everything off. They will totally smoke a motor at a constant full speed.

This thread is a few months old now, so who has had good luck with what prop on 4s in this boat ??

Thanks

[forescott]

I run the ammo 2700's on 4s @ 44-47mph.

NICE, stock props ??

[forescott]

I have both the 32 & 36mm pro machined venom props. The 32mm props work awesome.

I am now running the cf-40's on 4s with the feigao 380-9xl @ 55.2mph

Are you saying ALL new props must be balanced and sharpened before use, or just this particular one for the king of shaves?

Yes - if you want best performance and to save your drive system.

Hi Forescott,

I take it CF = Carbon filled and 40's = mm pitch?

[forescott]

Hi Forescott,

Yes, carbon filled. 40mm is the diameter. Pitch is 1.4

Thanks again
