Helicopter in-flight diorama help

Recommended Posts

So I recently picked up the new Kitty Hawk 1/35 MH-60L, along with the fantastic resin figures, and immediately thought it would look great as a diorama scene from the Battle of Mogadishu. I'm probably being a bit overambitious given I've never done a diorama, time will tell...

 

The big issue I want to decide on before I get started building is the practicality of showing the Black Hawk in a hover, with the 2 fast-ropes on the ground. I guess the advice I'm looking for is... is the best way to do this to use something like a clear acrylic tube underneath the model as a stand? Or is there a better way my un-diorama-trained brain is not considering?

 

I was thinking of using steel rod (wrapped in fabric) to replace the rope, and while I'm fairly sure they could support the weight, I realised that the bars which extend out from the cabin are going to flex under the weight.. and I can't think of a way to get around that issue.

I've seen a couple of examples of the same idea, but in smaller scale and the sacrificing of detail around the fast-rope system which I don't think I can get away with at 1/35.

 

Also.. can anyone recommend a good scale equivalent of fast rope? The one provided in the kit is much too short.

 

Any advice would be greatly appreciated!

Can you post a photo of the frame. Got an idea but need to see what it looks like.

you could add extra strength to the rope - helicopter interface by having figures still in the cabin grasping each of the ropes.  I hope that makes sense.

Hello, 

 

Here goes my 2 cents, can I be bold to suggest a frame with steel rod on the ceiling of the cabin roof. 

 

That way when the rope aka steel rod is attached into the the FRIES system, and here is the tricky part you can replace part of FRIES with steel rod, hopefully giving stability to the all thing. 

 

Hope this contributes to the brainstorm.

Just to throw an idea into the ring.

 

Could you make a replacement for the FRIES system from, say, soldered brass rod and then attach the FAST "ropes" to it so the helicopter effectively rests on a frame?  You might also be able to add some plates the inside of the replacement FRIES system so you could bolt it to the roof of the helicopter.

Thank you for the ideas guys! I'm sort of stalled at the moment anyway as I'm noticing some other kit mistakes that need to be sorted too.

 

I was indeed thinking about replacing the entire FRIES system, using steel rod for the slide-out bars. Need to think on what to use for the rectangular structure though

 

This is the type of FRIES we're talking about, because there seem to be two variants, an older and newer version. Typically the newer one would have been much easier to replace! 😄

If I was to replace it with a strong metal version, I'd need to figure out how to create the attachment points at the end (I think the red hoops can be sacrificed to make it work..).

And more importantly, how to attach the 'ropes' to the attachment points. My original 'fantasy' idea was to be able to somehow 'plug' the 'ropes' into the attachment points so that the model could be removed at will (for transport/cleaning etc). How to actually achieve that, however, is bewildering me...

 

@Jamie @ Sovereign Hobbies I've never worked with carbon fibre before, would you use it for the 'ropes' or the FRIES system itself? Could it be shaped to look like a rope? The steel rod I got is pretty strong, although there is naturally a bit of spring to it... but the advantage is that I can coil it at the bottom to give as sturdy a base as possible.

You might be able to source the rods for the rectangular structure from Albion Alloys.

Yes, thank you! I've just had a look at some of their stuff. I reckon a U-shaped brass rod could be turned into more or less the right shape, then the slide-out bar soldered on and the brackets added from spare PE.

 

Would a soldered joint be strong enough to support the weight? I've had mishaps with over-estimating solder before...

Found a German site, Modular, which offers the perfect dimensions in rectangular brass bars, so that's a start!

 

As regards to attaching the rope to the FRIES, I was wondering whether the top loop of the metal rope could slot in the top of a short, plastic tube, and the rest of the rope could then slot into the bottom when the model is positioned, also making it removable. If it was a tight enough fit then it shouldn't wobble.

 

Not sure if I explained that well, so here's a very crude illustration 😄

Obviously it isn't accurate in any way, but if it worked it might be a sacrifice worth the end result. A big if, though!

CF is just very rigid, and once cured will resist any shape changing efforts. The commercially available rods are fully pre cured. They're very light for their considerable strength and are easy to bond with epoxy or superglue. The R/C aeromodelling community likes them for lots of things, but a typical example might be control rods between servo and control surface where it's imporant that the surface itself moves predictably with the servo and in accordance with the transmitter stick rather than buckling.

 

It's usually possible to get a good fit with brass tube so your dio could be dismantlable for transport if needed.

 

The carbon fibre rods may have a better chance of holding a helicopter at the top of a "rope" than steel would, particularly since the weight at the top will be offset and will encourage the "rope" to bend over.
