China Strut and Rudder 1/8" Drive

[jetpack]

I'm looking at this off one of the eBay stores for a couple of my builds but I have questions on what actually are my prop options with it.

I have wrote the seller but no reply as of yet and was wondering if it is a 1/8" propshaft diameter or if the prop shaft is all metric on it, including the thread size. The reason I wonder it is not completely metric is it designed for a 1/8" cable and stuffing tube with liner. Thats why I'm hoping to find someone who actually owns one.

I am asking the fast electric crowd about it because I don't really know too much about your type of hardware sizes and such. I'm really hoping it is an 1/8" propshaft stub with 5-40 threads like how the standard Dumas/Octura hardware is made so I can swap bits with those items if I like.

I have spotted this and wondering if it would go along with my Dumas 1/2A projects where I use Cox type engines that can only swing a 1" diameter prop, which are only available with 1/8" bores and would like to stay with a metal prop. A hard combination I am finding out to come up with.

The size and looks of these parts would work beautifully on these hulls and have me drooling, but my luck is they will probably be all metric in the prop and shaft department, or unable to convert. Thanks peoples.

I guess it would apply to this variety also. It's the same seller, but not sure if it's the same maker. Can anyone comment on any drawbacks on either ones quality or steer me to one of your threads that feature it?

I'm actually trying to come up with all of my options on micro gear, but really trying to stay away from carbon props and metric sizes. I have looked at Offshore Electrics, Microhydros and Fullers too.

Hey Dave~

Not getting too much help on this one eh! Is it possible to press out the bushings or re-bore to accept standard/imperial 1/8 hardware. Just a thought.

regards Jeff~

Hi Jeff,

No, no bites yet but I'm still fishing. I did get a nibble over on the other site, but the jury is still out on it.

The person that replied was familiar with this guys hardware, but not his current stuff like this is. He did however find out the prop that is on the display is a 1/8" bore prop, so thats a bonus. He didn't know if the stepped propshaft where it rides inside the strut was standard, so it is still a partial guess and is assuming the maker has been trying to cater to the U.S. market standard sizes with it.

He also was familiar with his drive setups, using a square drive at the strut and know they have a tendency to vibrate a bit. With that being the case, a soldered 1/8" flex and prop shaft is probably now in the mix for sure.

What your suggesting with re-bushing/resizing it really isn't out of the question. It just might be difficult if the empty strut bore is machined metric and the bushing ID is oversize 1/8". If thats the case, thick walled bushings will have to be found, pressed in and then reamed to standard.

We'll see how it goes. Like I say the seller hasn't replied yet so maybe theres good news still comming.

Thanks for the suggestion and interest though! I'll update this for sure for others when I know for sure whats going on.

Dave

jetpack - Looking on ebay right now at the exact same item and the description clearly states that it is for the 1/8" cable setup.

never mind... just read that you figured that out

Yeah the cable itself is 1/8" but doesn't state for sure if the propshaft is 1/8" inside the bore or what, but that's okay I just recieved an answer saying it is all imperial sizes as far as the propshaft is concerned, so it looks good to me.

I was worried it was a mixed size between the supplied 1/8" flex and what the actual propshaft, bushing, nut, ect was machined to, metric or standard. Sometimes they mix, and with this being from overseas it could have been possible. Thanks!

I would go further on saying if someone was interested in this outdrive, the best bet would be to go with the "no propshaft" offer (he carries two packages, one with and one without square drive flex, stuffing tube, propshaft assembly) and make up your own from Octura or Hughey, ect...and get away from the square drive coupler at the propshaft.

The only advantage of having the square drive package is if your flex breaks, you dont loose your prop assembly out the back due to there being a stepped shoulder to hold it back, but otherwise the square drive will vibrate and rob power.
