Accurascale Class 55 Deltic - 4mm scale


Recommended Posts

Thanks Fran.

 

That does correspond with some of the stories of former drivers of the Deltics, earlier in this thread, so well done.

It certainly looked impressive!!

 

I doubt the 4th radius curves I use will handle that, with it's mass - still ~650g?  (you'd said you were dropping down from the original target of ~700+)

 

Having had experience of higher revving motors using 'dogbones' in R/C, are the driveshafts metal, C/Fibre or still plastic?

It's easy to for me to comment, and often manufacturers prefer a 'sacrificially weak' area to avoid more expensive parts being affected.

In this case, if you reinforced the driveshafts and outdrives / cups, you would transfer the potential excessive loading onto the motor itself.

 

Sorry, I waffled.

I was impressed with the speed - possibly exaggerated a little by the scenery.

Hi Al,

 

The Deltic is being made with tried and tested components had has been extensively tested (as per the recent videos give a glimpse to) so there will be nothing to worry about. Also, you can check out the feedback on our metrovick locos under the IRM banner to see feedback on running characteristics and quality as they share a very similar setup.

 

Cheers!

I know, getting a bit slack!  It did look more than a scale 120mph.

Perhaps I'll do it 'Sam style' over a flying 3 inches ... 

It "did well over the ...."

Al.

 

I think the most important thing to take from that wizz by was how well and sure footed it was over finescale track with P4 wheelsets.

 

Cheers!

I thought stated weight of the Deltic was around 760g, or more with DCC chip and speakers?

When was this reduced?

The 'final' curb weight of the model, complete with all fittings, dual speakers, super capacitor bank and a decoder, is 813g on the rails!

I suspected the sound decoder and associated equipment might nudge it over the 800g mark. Wonderful!

Don't know what to say - that's a full-on heavyweight - the momentum at that 55" beggers normal OO-scale belief!

What have you used, depleted Uranium?  !!

 

What did you scrimp on?

A little short of 1kg !!

 

Al.

 

The factory ran out of depleted uranium, so we had to make do :)

They're saving it for the Polaris submarines you're going to announce in the New Year.

They are going to do DCC enabled realistic loads for the KUAs...I knew it... as cunning as a Professor of Cunning at Oxford....

Looks like my layout will be closed over Chrimbo for bridge strengthening works then! 

 

I was thinking that (in general terms, my layout such as it is will have no load problems)....

The weight is distributed over two bogies. Are there any other modern 4mm scale rtr models (steam or D&E) where over 400g is concentrated on either one bogie or a single set of 6-8 driving wheels? The new Hornby 'Dublo' diecast duchess comes in I believe, just under 400g, with majority of the weight on the 6 driving wheels.

 

I specifically didn't mention axle loading as the Dapol 68 would walk this as it only has 8 rather than 12 axles!
