Stingray Build

[Subculture]

You can Du-B bearings. these are bornze backed bearings with PTFE. They can run dry but they're designed to run best in water, as it helps keep the bearing cool, no other lubrication required. Norbert Bruggen stocks them, you can also get them on fleabay.

I can give you a link for some exquisite little motors with planetary gearboxes, available on ebay, they do about 170RPM on 3 volts. Any good?

Cheers Subculture, I would appreciate any help (Links etc) you can give.

Hi Guys,
The target speed for the rotor is about 65 - 75 rpm, interestingly, the rotor does not provide forward momentum at all and holds a steady rate of spin whatever Stingray's forward knot speed maybe, even if that is zero. I have been studying the cabin layout and should be able to produce a CAD drawing soon (walls and floor plan). This is for the static modeller really as I am not sure what would happen if left to free flood. I know David is the expert here so was hoping for a little guidance?

The Cabin vac forms are done and successfully test fitted one lamination of 1mm PetG with a 2 mm lamination of styrene directly over to produce the outer skin. Windows will be cut in the styrene layer and a perfect fit maintained. Mamas, you are a clever guy....

Just a quicky, The Ratemaster as discribed is a Contra Rotating Anti Torque Eddy Dampner, OK that was a bit anoraky but It may just work as a trim function. As it stands its a side to side paddle. So, It could affect the forward direction one way or another depending on which way its spinning. Of course it may not do much at a low RPM but it will be interesting to find out. If it works lol.

Bernie,

You know I can't resist doing an interior. You may know, but that XL-5 model I built for David Hersh (Starlog staffer) nearly forty-years ago featured not only a detailed JR. cockpit, but a fully decked out 'secondary control station' atop the main craft (I believe the model is now in the Greg Jein collection). I've gotta convert those slides to digital files one of these days.

I'll give the STINGRAY interior the same treatment I did for the 1/96 SEAVIEW. Like, below:




No problem making it free flooding.

NICE!!!! This is the stuff I have seen you do in the past, cant wait to see what you do with Stingray.

[He Who Shall Not Be Named]

I've improved my figure building skills since the SEAVIEW job, example is the recent figure work in support of the 1/72 FOXTROT project.



Ironic, I got a bunch of 35mm frames from David Hersh in exchange for the XL-5 model -- most of them interior shots of the STINGRAY cockpit. I would have Phones and Troy in the front seats, with Marina on the couch behind them (talk about lavish! A couch and appointments right behind a warcrafts front-office). Boy, could those Century-21 guys imagine!

Mamas, what's the scale of this model?

David

[RCnut]

David, Your eyes must have magnifiers in them lol. This is why I try and stick to largish stuff. Scale Would be around the 1/35 mark. Bernies been burning oil in the night and he agrees that its about right.

[Subculture]

The target speed for the rotor is about 65 - 75 rpm,

In that case a bog standard servo should be close to bang on, as they will do that sort of RPM out of the box.

For Du-b bearings, Norbert sells them in small quantities (can be difficult to get otherwise) http://modelluboot.de/Zubehoer/Dichtungen.html#WDR

Here's a link to an english PDF which tells you all about these bearings- http://www.nomo.se/pdf/DU-gb.pdf

Having said that, I'd have thought straightforward delrin bearings would be more than sufficient for this sort of application- low rpm and minimal load.

[RCnut]

Well to be honest the first working one I posted on you tube had brass tubing and it worked fine, just me trying to be a bit flash with the bearings and such lol. so yeh delrin, brass bushings will all work.

I use those magnifying goggles a lot these day.

1/32nd. Excellent. Twice the size of my 1/72 figures. That big I should capture the caricature features unique to the Anderson marionettes. There's a Mike Mercury in there too I think. Oh yeah ... I'm thinking SUPERCAR. How bout you, Mamas?

David

[RCnut]

You can sculpt too huh! And you hate ME! lol. Supercar....funny you should mention that, I had the moulds from ENA ( Product Enterprises off late) a good few years back and did a Ltd run (2 footer) Complete with an excellently sculpted Mike Mercury. Long gone I'm afraid.

[He Who Shall Not Be Named]

I can almost sculpt. My Dad was the true pro at that Craft. Still learning how. Wow! Would love to have been in on that action when you were active on SUPERCAR, as that vehicle was my first love.

A large r/c version of that thing is on my bucket-list.

Here is the closest I got to sculpting- did this years ago for special parties and Halloween with my best friend. My friend actually got some work in the movies.

Some quick reference for the main characters, give David something to work with, big head, small body, not proportional unfortunately but full of character nonetheless....
