Hi guys whats the best propeller size for my Oxai Aries for flying P09 using YS 170DZ and what is the best rpm. Thanks

Hi, yepe

Here is one information for YS170DZ propeller and the rpm. http://www.vit.or.jp/%7Etomo/gami/so.../souzya84.html
According to it, they convert APC 18.1 x 10 to 17.6 x 11.7 and its rpm is about 7700 at that time.

On the APC Web Site the weight of their 17x12 propeller is listed as 0.0723 pounds (32.8 grams). The weight of their 18.1x11 is listed as 0.29 pounds (131.5 grams).

Is there really that much difference in the weight of the 2 propellers?

Yes, there is. The 18.1x10 has a much larger and heavier blade.

hi yepe

I wonder where did you buy your aries and who did you contact. I am in Thailand and i am trying very hard to send MR. Roger Mao saveral emails to get one Aries into Thailand. Well, I sent him emails since last month and there was no reply.

Thanks

Hi Bob,
I've just weighed my APC 17X12 and the scales say 121 grams/4 1/4 ounces, so just slightly less than the 18.1X10.
Best Wishes,
Alan.

Rune

is the 17x12 the same as the 17x13 we used on the Os some year ago exepet for the 1" pitch??

Wasson

Alan,

Many thanks for definitive data. Much appreciated.

Have you tried an 18.1x11 and if so did you source it directly from APC or did you find a UK supplier who has them in stock?

Kind regards

Bob

Sorry Bob, can't help there-I've moved (partially!) from 2-stroke, straight past 4, to no-stroke(electric).

Psookdee,
I got my oxai aries from Mr. Alex Lau of HongKong. Try emailing him with this address [email protected]. I heard from a friend that Extreme Composities is manufacturing Altair and it would be release this May. Altair is the same design as aries the only difference is stab.

Guys,

Tried the modified APC propeller of Naruke, the prop is very nice far different from 18.1x10 and 17x13. The speed is linear and constant, even you advance to full power the plane speeds up slowly.

Presently, X-treme only manufactured the mini version - 110 size. The Altair also has a slightly different wing dihedral than the Aries.

Just correcting Yepe's post. The Naruke prop is an APC 18.1x10 modified to 17.6x11.8. Work just great.

Hi all

CPLR uses APC 18,1x11 (17x12 when wind is strong) on his Osmose. Stéphane Carrier uses 18,1x11 on his Intégral.

The propeller depends a lot on your flying style, is not just RPM, we use 17x13 on the 160 and 170, depends on your field elevation and wind, I sugest you get the 17x13 and 18.1x 10 and try them, it also depends a lot on the airplane, after you try them adjust the throttle curve so power is linear, this way you can which one is best, throwing a different prop in the engine is not enogh.

Try this way and you will be happy with the results, your airplane will fly a little different from on prop to another. If you are flying F3A then keep in mind not to exceed 7800RPM.

have someone tried this

I have heard that prop had nice breaks but no speed on an RX. Don't think anyone has tried it on a DZ.

Troy Newman

yes we have...its very noisy.

too much diameter. The 18.1's are a little too much diameter too. At least for my taste I have been clipping them and working on them now for about 2 years.

The 18.5-9.5 is also very heavy, and takes a special cut spinner. It weighs a signifigant more than the 18.1-11 or 12 props.

even if the ys170 uses 20% fuel and ignition would these props work on the oxai aries? canI use 10% on these props?

bwick

Depends on your flying style, but I really love the 19x11.  I flew an Oxai Aries last year and this was my prop of choice.  If you can get a hold of one give it a try.

cchariandy

Brett, are you using the 19x11 on a non-CDi 170?
