OSE prop alternative for barbwire?

[kevinpratt823]

Does anybody know what prop would be equivalent to the stock barbwire prop, that is available right here in the OSE store?
I'm not looking for an upgrade necessarily, just replacements for when my niece/nephew run up on the rocks or run eachother over..........Thanks.

Kevin any ideas on the stock specs? diameter and prop shaft size? drive dog or threaded on?

Steve I'll get the calipers on it when I get a chance.

A quick search shows "size not given by manufacturer",..... because they want you to spend $5 ea. from them of course.
Calipers show 30mm dia., approx 13mm from tongue to blade tip measured along the shaft(pitch?), and 3mm shaft w/drive dog...............
Is this an oddball size so you have to get theirs?
Steven, if you really want I could mail you one of mine to size up if you think it's something you want to stock, just lmk.

3mm is a bit of a pain, but 3mm is only .17mm off of what an 1/8"(3.17mm) shaft is. so you can use a 1/8" prop with a piece of tape wrapped around the shaft to take up the slop. Im going to get a bunch of the smaller cnc props in about 6 weeks, you can also you the octura x430 or x632 if you think it will spin it.

The Octura x4 or x6 series props props with I/8" bore fit the drive dog but as said simply wrap the 3mm shaft a couple of times with some plumbers ptfe tape. The prop is that close a fit on the shaft you can get away with no tape as well.

There's one other item to deal with and that is the slop of drive in strut. There is to much slop there. I measured .006 slop which is to much. I searched for a replacement part and no luck. I tried improvising by using plastic 1/8" tubing used for airplanes. I put new tubing in and inserted the wire drive and put oil on wire at where the wire is in strut. Next I put ca clue in the full length of plastic tube and let harden. The oil kept the wire from sticking to ca. Now it didn't work as ca didn't fill the entire plastic tube even tho the tube was 3/4" in length. I sent the boat back and got a part payment back. I gave up which I never do as I spent enough time already on it.-------BTW in post #6 about tape, it works out great as plastic props don't need balancing. Also STEVE mentions 4mm props and 1/8" and using shims works perfect, been there.

x632 runs excellent on mine planes instantly same temps as stock makes the boat a diffrent beast

I'm running the Octura X432 and it works great and made a nice improvement in speed. You'll want to step up the ESC. I'm running an Atomik Pro Brushless Marine 50 Amp ESC with good results.

There is one HK prop 32mm Diameter and 3mm bore CNC. You look and you will find. Once you tighten up the nut against an Octura prop and it presses against the drivedog it should be good to go. Most Octuras that small have a nice flat square surface to mate against the drive dog.

Thinking about an upgrade for the Atomic as well..

Whats the difference with the X632 and the X432? Above, it was said that the 632 did not effect temps, but made the boat more responsive?
