Just about any on line hobby shop should be able to set you up, Offshore electrics is a good one.
You won't find a specific prop for your boat, you will be buying something aftermarket from Octura, ABC,Prather, grim racer etc.
If you know the diameter and pitch of the original you should be able to find something really close to it aftermarket.
Is it a 3/16 shaft or 4mm? In N.A. we don't see much of the metric stuff, but I think Graupner has a line of metric shaft props. Or you could use an adapter or ream the prop out to fit the shaft depending on the size.

arpro 1

Offshore electrics.com has carbon fiber props-34.5mm-36mm-also " K " like Like Mr. Pompebleb mentioned. Look for carbon props 2317.40=40mm and etc. I'm not trying to out due Mr. Pompebled, just adding to his post. He's areal gentleman in my books!!!! I see Istanbul- i wonder if Germany or U.K. at Aztec hobbies can help as they would be closer to your area. Just a suggestion only. I also have a Arpro 1 with a 36 40 05 3900 Turnigy motor and placed motor stem 4" ( 100mm ) from transom and use flex cable and extended the rudder 1" ( 25mm ) to match the dog drive. Have a good day! Yes, i know, i talk to much!

Hi BB,

The stock props are plastic and not very strong, I shortened the propshaft on my ARPRO on the motor side, so I could add a washer and a nut.
This way I was able to run the Graupner 2318.xx K-series props which are much stronger and last longer.

If you run the stock 1520KV outrunner on 3S, you can go as big as a 45K prop, start with a 40,5K to be on the safe side and check the temperature regulary when testing new(bigger) props.

Finding a source for the K-series props can be a problem, try eBay.

Regards, Jan.

Hi beach

If your ARPRO is standard then you need a drive dog 4mm P1.4 prop.

you want either :-

1.
http://cgi.ebay.co.uk/PROPELLER-X438...item1c1a093d26

OR

2.
http://cgi.ebay.co.uk/PROP-ADAPTER-3...item230efb0364

AND


http://cornwallmodelboats.co.uk/acat...lers_2317.html

or you could go :-

3.
http://www.storacingproducts.com/spa...at-spares.html

if you go #3 make sure you buy a few they'll shatter.

Hope that helps

Most drive dog type props are 3/16" which is slightly bigger than 4mm which is on your ARPRO. You slide adapter in to the prop which shims it up.

I seem to remember my ARPRO ran best on an octura X442. PMB do them, balanced and sharpend for around 15 + post.

A good upgrade for the ARPRO is

Just get yourself a 5000mah battery, and you've got a quick boat.

wow, amazing things you re talking about but it is so bad that i dont understand much about upgrades

first i buy the propeller and the adapter, and the motor after that ( is it easy to change the motor ? ) and finally a 5000 mah battery ( will it fit in the boat ? wont it be so heavy ? and when i put it on the left how will i balance the boat ? )

thank you so much and sorry to take your time...

Arpro 1

Istanbul; remember the pictures of the original A 1 where the lipo was setup with battery on the left. The boat straightens out once you pull the trigger. The weight difference btween 5000 and 4000 isn't enough to make any difference. Whats missing here is you have torque roll to the right to start off with and the lipo is on the left so it balances itself out when under way. Also when you setup a mono that you have built or revamped, the strut must be set so it veers to the right to combat the torque roll even with duo batteries ; one on each sie of the motor.This distance is about 3/16" of an ". Now if i remember Ferral of Australia revamped his Arpro 1 by placing his motor way up front and placing his duo lipos toward the rear and alittle to the left to combat the torque roll. You figure, just a 1/2" of both toward the left is enough weight to do the job.
