New item TFL Outdrive and motor assembly.

I mean look,at how the engine sits on the mount at basically a 90deg angle, hard to get a flex shaft to last that sharp of an "S" bend like that. I bet it's bevel gear driven like the Arrowshark unit, just a smaller version.

Yeah, exactly, this crossed my mind, but I didn't want to speculate, guess we will wait for Steven to clarify.
Since it sounds like you are familiar with the more expensive Arrowshark unit which I am not, are the bevel gears machined in such a way that it can only go one direction?

[DCMW]

No the gears in the AS unit are straight cut, so you can spin them either way.

[DCMW]

Straight from arrowsharks website:
The M8 gear set is not machined from just standard hardened alloy, but from alloys made with a compacting process of powder metallurgy; this is the same technology used for gears in full size automotive transmissions.
The gears have thicker and stronger teeth designed to permit engines up to 10hp to be used for blistering speeds. As well, the gear design allows for counter-rotation when you go for the ultimate and fit twin M8 drives on your boat.

SO if it's made like the AS unit we are good to go:)

[tlandauer]

Awesome, thanks for the info!

[DCMW]

Hopefully it's gear driven:)

Hi Steven and moderators,
I just realized I got carried away a bit , please delete my posts if you deem necessary, I didn't mean to go off topic here in the TFL product thread.
I love these units BTW, they are as I said earlier beautifully made and I have to find a hull to do justice to them!

Not really, if they don't provide CCW flex cable, you will unravel the cable. Assuming they use cable to transfer energy from motor to prop shaft.....
I am making this a point because I want to build a twin Out Board Pursuit and i have the TFL mini OB, the problem is no one makes a custom CCW cable for that unit, it is square end 4 mm cable. I have been researching and so far no luck, therefore I am flying Multi Rotor Quads to kill my time . lol.....

4mm counter rotating Flex with square end you get from TFL

yes the gears are straight cuts. here is a parts diagram.

[cybercrxt]

Wow, so they really are gear driven, and it looks like all solid shafts, so no need to worry about unraveling a cable!

[kwiktsi]

That's what I was assuming as well based on the shape of it all. Good to know it really is gear driven. Wheels are turning for this. I'd think they'd be a little small for mean machine, no? I'd like a more scale looking hull though. Maybe even a twin pursuit instead of a cat?

Yea if its run by flex you would need a counter rotating flex but sure does look like a gear driven unit to me...

You may absolutely correct, Mr DCMW! Keep an eye on here, you will find out the truth. :--)

Monica
can you post the dimensions of the unit.
Thanks

Hey, thanks!
I will ask, last when I investigated, the strands are not identical, they don't feel the same in my hands. I would have gone nuts with that situation. But may be just the one I got?

[tlandauer]

Wow, Steven, thanks for clearing this up!

[tlandauer]

Monica! Greetings! Good to "see" you again!
TFL is looking great! Say hi to Mr. Ke for me!!
