A Little VC-Tenderness...
« on: June 21, 2019, 10:23:18 am »
For this GB I shall be attempting not to ruin the looks of one of the most beautiful and iconic Jet Airliners ever built...
Inspired by Rolls-Royce's RB211 Engine test bed XR609/G-AXLR
see here: http://www.vc10.net/History/Individual/XR809.html and the fact that at one point when they were converting the Ex B.A. VC-10's to K.3 K.4 Tankers, they'd considered replacing the RR Conways with IAE V2500 engines, I thought why not replace 4 Conways with two RB211?
I've got two Braz Mod RB211's and the newish Roden VC-10 kit to be going on with.
The trouble is the Engines are made of resin and are quite heavy, especially if your going to be putting them at the very back of the Airframe, I may rummage in the spares box and see if i have some injection molded RB211ish type engines. (possibly from the Minicraft B757 the RB211's were intended for).

I did a model of G-AXLR a while ago, that may provide some tips for the engine installation. Note that G-AXLR used an engine meant for underwing pylon use, hence the big fairing on top. Presumably a production version would have a neater installation with no need for the fairing.

and yes, it's definitely a tailsitter (even with just 1 BraZ engine).

I did my VC-10 AEW5 using the engines from the Revel Beluga kit.

Yes, both are excellent builds, :thumbsup:
 I only hope that mine turns out as good as them.

The three engine VC10 has been done in the real world.   Wikipaedia sayeth:-One aircraft (XR809) was leased to Rolls-Royce for flight testing of the RB211 turbofan between 1969 and 1975. On return to the RAF, it was discovered that the airframe was distorted, possibly due to the power difference between the RB211 on one side and the Conways on the other. It was considered uneconomical to repair and was partially scrapped, part of the airframe retained for load training

A twin RB211 /Trent engine VC10 is however still whiffable!

That was G-AXLR that Hobbes mentioned above.

There were at least two tri-jet proposals, the more extreme being a double-decker
with three RB-178.

Often thought of similar stuff, like a twin-engined 727. This sounds great!

Now where were we?
Ah yes the obigatory box top and contents shot:

Interesting to note that although its a fairly recent moulding, 2016?
There was a fair amount of flash on one pair of wings, and some of the sprue gates are placed on the mating surfaces of parts
or on the leading edges of the wings requiring careful sanding. Fit so far seems quite good <_<
Compared to the ancient Airfix kit, (1964?) its much finer although with a bit of work i think the Airfix kit will still be able to stand alongside the Roden kit.
The Roden Conways are much better than the Airfix kits though.

Not sure when I'll finish it as I'm currently flitting between Germany and Sweden (got to earn Money somehow :rolleyes:)
Anyway a quick mock up to show where I'm trying to go with this one. Note the lack of RB211's mainly because I didn't bring them with me
because I'm temporarily unsure of there location in the stash :banghead: However I did find two plastic molded RB211's. The trouble is
one is a RB211-535C (as fitted to B.A.'s early B757's) the other a later RB211-535E4, hopefully I'll be able to find their partners somewhere.
One other thing I wanted to do was to extend the wings a bit: :o
Now there are two ways of doing that, one can add extensions to the wing to make it longer or you can do this.....

On reflection having studied the photo's a bit I think the winglets need refining, they look a little to broad in the cord, and I might adjust the rake to match
the Fin's rake back on the leading edge. Which would make them appear finer :thumbsup:
