Total Immersion Disney Nautilus build.

Trying a little casting. Pulled these from a Vosper kit. I need to do some refining. Air got trapped in the bottom of the mold, but three of them could be used for something.

Finally got my brass balls. If I find time today, I'll bore one out to assemble the pivoting prop shaft. Wasn't sure what size I would need so I ordered 5/16 and 3/8. I'm going to try the 3/8 I think. Found them on eBay from a hit n miss engine shop for under $9.

A bit off topic, but I've been trying this lipo pack from Hobby King. Way better than the nicad pack that came with this JR9303. I used to have to charge before every use. I've only charged this pack twice in the last 7 months! I think it goes for about $12 plus shipping.

Tiny bit of progress fit into my tons of other tasks I need to do.

I got the base formed for the propeller pivot.

[Buellman1]

It needed a stand. Had some pieces of Walnut sitting around.

I'm back. New schedule at work doesn't leave me with much free time these days. I've almost caught up on my house work and trying to get back to building. So, I've spent my evening building this contraption to pivot the propellor shaft. It's still not done obviously, but I think it's turned out fairly decent.

Nice! You'll be amazed at how well the boat handles with the gimbaled propeller.

Nice! Looks well thought out. Itll make more sense to me with more pictures later on.

Thanks! So it has to be installed yet and I'm debating how I want to control it. I could do the standard one servo for "rudder" and one for "elevator". But thinking of my helicopter and plane mixing combos, I could program Elevon (aileron/elevator) control. That would mean both servos run and I set my contraption diagonally in the hull. I'm also going to try and let the actual rudder pivot free. I don't want any external pushrods unless truly needed.

Dave, I have some questions about the gas system. I appear to have a type 212 driver. Can I put compressed air in the tank for tuning n testing? If so, what's max pressure I can apply? And finally, how many tank blows should a gas system be capable of?
Thanks,
Gene

Proposed diangonal install for Elevon control.

[greenman407]

OH, now I see what you are doing. Pretty smart. Should work. Maybe down the road you could install a self centering bearing on your gizmo there.

Hey, Gene,

with air at 300 psi you'll store about a half of a cats-fart. With a liquefied gas: about 10 complete blows. And if you charge the sub-system to over 300 PSI of air you'll pop the hose, knock the planet off its current axis, and upset the space-time continuum! Use liquefied gas, damit!

Or are you counting on Obama-Care to pull that copper cap out of your forehead?...

Yes, that's the stock 212 SD -- more ass to that motor, and it's also geared down to swing that Victorian, ugly-ass, axe-blade propeller


Stop over-thinking the control surface linkage (OK, propeller shaft linkage ... Jeez!), helicopter-boy -- install the gizmo in there as I show you, then get on to the 1001 other tasks you need to do before you can get this sucker wet.

Don't get cute: engage the rudder -- this pig needs all the yawing force you can muster! Don't be a slave to scale fidelity.

You do very good work. Proceed!
