Bristol Scout C, Gavia 1/48, Upd 19.6.2021 Cowling

[Bughunter]

Bristol Scout C  
 


Some of you asked already what's next - I have some shelf queens but as promised in Richies Scout scratch build I will join with a Bristol Scout. As usual in 1/48.

I have both Gavia kits in my stash, the normal (allows 2 markings) and the Professional Edition, which is like the Eduard Profipack, allows 5 markings, add a nice PE set and two resin cowlings.
Another accessories will be a Part PE set, Gaspatch turnbuckles and as usual a resin engine made by Small Stuff.

Since I like to have the Union Jack in my cabinet I think I will build this one:

Other references are the Windsock Datafile 44 ...


and of course the great photo collection by Richie on Flickr!


That marking brings up the first question. Many different rotary engine types were used on the scouts, at least the 80 hp types Le Rhone 9C, Gnome 7 Lambda and Clerget.

I have the Small Stuff sets for the Le Rhone 9C and Gnome 7 Lambda, but I think the 1250 was using a Gnome 7 Lambda, according to the picture on page 9 in WD44. Are there any dissenting voices or have I overlooked something?

I hope, that the diameter of the Lambda is a bit less to get it under the cowling

The progress will be not that fast, as I have to sort out important private things.

I hope that some of you will follow this little group build!

Cheers,
Frank

Definitely following this one Frank, looking forward to some more Bughunter magic.

Looking forward to your build Frank , Between this build and Richies it might be just what I need to finish my in the stash .

I cannot comment on the engine Frank as I do not have any sources to consult, but in any event you will probably be making your own cowling from metal so I would guess that ultimately the size of the engine will be academic: your new cowling will fit!

[Manni]

Ah.... The next miracle-build. I will sit down and watch with interest.
Bye, Manni

[Fvdm]

I will certainly follow this one.

[Gisbod]

You’re a machine Frank!

Lovely subject.

Hmmm, I love the Bristol Scout! bring it on, Frank, ease the waiting until the CSM 1/32 release! I am keen on seeing your magical soldering iron at work!

Wow, what a great interest
Welcome Alexis, Rick, Richie, Stephen, Manni, Ferry, Guy and Andreas!

I was not really able to work on this project due to private things, only some small preparations are done.
At least I was able to do some research.

That marking brings up the first question. Many different rotary engine types were used on the scouts, at least the 80 hp types Le Rhone 9C, Gnome 7 Lambda and Clerget.

I have the Small Stuff sets for the Le Rhone 9C and Gnome 7 Lambda, but I think the 1250 was using a Gnome 7 Lambda, according to the picture on page 9 in WD44.

The engine thing seems to be mode complex than I thought.

There is a clear statement in the Profile Publication 139 "The Bristol Scouts C & D"
"The standard engine was the 80 h.p. Gnome rotary and was fitted to 1243-1266, .... when they left the factory." And later another interesing sentence: "The Admirality regarded the Gnome as more reliable then the Le Rhone and therefore demanded that R.N.A.S Bristols must have Gnome engines in view of there liability to have to fly over water".

Ok, as I want to build the 1250 (or the more colorful 1246? ) both are in this range.
I have the Gnome Lamba 80 h.p. from Small Stuff, it is a 7-cylinder rotary (the kit engine has also 7).

What confuses me is the Windsock Datafile 44 on top of page 37.
"Power: One 80-hp Gnome Lamda, 80-hp Le Rhone 9C, .... the Clerget 7Z and the Le Rhone 7B had seven cylinders; all others had nine."
Is this a mistake or does anybody know a 80-hp Gnome Lamda with 9 cylinder?
Also the doubled Lamda-Lamda had 14.


I started to build the Gnome for checking. The valve rocker are missing, but it looks promising on top of the plan.



Okay on the plan, but not on the kit cowling!



The cowling on the plan shows the missing space! I checked the printed ruler on the plan, it is in correct size.



So I painted the engine to be able to add the small parts to check the final size. Ignition wires and washing is missing.



This will probably be model building again instead of gluing the kit together, as Ken put it so nicely.

Cheers,
Frank

What a lovely engine Frank! And what a great subject - one of my favorites so I will follow with rapt attention! Regards, Marc.

[RichieW]

Great to see this underway with your usual beautiful engine. I'm looking forward to seeing how you solve the cowling problem, I think there might be a bit of lathe action in your future! 😀

I really should know about the engine but sadly I'm at the age where things get fotlrgetten as soon as I learn them.

Great to see you back at the bench, it's just not been the same without you!

It's a shame that 3/4 of this will not be seen hidden under the cowl , either way beautiful work Frank

It's hard to believe that engine is 1/48 scale...what a beautiful job you've done on it, Frank. The cowling issue would make a lot of modellers just start a new project  . I'm anxious to see how this progresses.
Cheers,
