Building a 1/3 scale Bristol Scout has been one of those projects that has been gnawing away at me for what has probably been years. I decided I would finally scratch that itch and build one.

Initially I began drawing up my own set of plans but the more I searched for information the more I saw Brian Perkins' beautiful model of the Scout. Well, there's no point in re-inventing the wheel, so i made contact with Brian. In short order a package arrived at my door with a big set of beautiful plans. I just hope I can do Brian and his plans justice !

One thing to be learned about building what could be called un-conventional sized models is that you have to use un-conventional modelling methods. No pinning strips of balsa on to a board for this one. You can see in the photos I made a jig to build the fuselage sides so that they will be identical. I also cut out the two front fuselage doublers from 1/4" aircraft ply by screwing two blanks together and cutting them out similtaneously. I've also included two photos of Brian's model which provides all the inspiration you need. It looks and flies fantastic.

A bit more progress done.

Fuselage is coming together. I slotted the rear section and put thin ply laminates in to get the correct curvature at the rear as Brian did on his. The tail skid slot is not completely cut out here as I kept a little bit for added strength while the clamping and gluing was going on. I also used a duplicate piece just for the shape on the bottom (top really) that wasn't glued in and will be removed when it comes off the board. Still to cut the front formers and add them next. Everything coming together nice and square.p8280621.jpgp8300630.jpg

It's been a while since I've posted anything and I have made a bit of progress. Here you can see the undercarraige wire ends ready to be brazed together. The UC wires took two attempts to get right. After bending they were sandwiched in ash wood legs glued together with aircraft grade epoxy. The legs were sanded to shape which took a long time. I had no idea how hard ash was as I had never used it before. The tail skid is done (photos to follow) and I deviated from the plan a little. I fabricated the steel mounting brackets for the front and rear of the legs too. Undercarraige  mounted on to the fuselage - just the ash spreader bar to add. I made the ash tail skid using the dimensions from the original 1914 plans. I found the drawings at the great web page "rebuilding grandas Bristol Scout." There's quite a few original drawings there. The skid came out a little thinner than is shown on the plans and I'm not sure I'll use it yet. I'll see how heavy the whole tali ends up, so I might change to Brian's original design. Shown here too is the MDF former I cut for laminating the rudder. The rudder is actually completed - photos to come.uc wire ends mod.jpg

It's been a long time since I've posted an update. The rudder and stabilizer are complete (photos to come) and the other day I machined a couple of keepers for the wheels...p1010004.jpg

Dave I believe the video is of the original built by Brian Perkins not Ian's, Ian is using Brian's plan.

I hope nothing has happened to Ian as its quite a while since his last post?

Gentlemen, thanks for the postings. Yes. I'm alive and well. The Scout is still under construction albeit rather slowly as I've been distracted restoring vintage motorcycles and playing around with a 1931 Form model A. The engine has been installed and the undercarraige is complete. I need to post a few new photos. David Bremner, the builder of the real Bristol Scout kindly sent me a piece of the material from his plane after stripping it down to recover. I'll be placing some of that on the model. I had all the ribs laser cut and just need to shape the spars and form the tips to start assembly on those. The bikes are mostly done so I'll be back to the Scout soon.

Dave your, correct in that it was Brian's model that was in the video. Mine is still bare frame at the moment.

I will be getting back to it soon and posting more photos. Thanks for bringing up the old thread again.

Looking forward to the pics Ian. I followed David Bremner's blog and what an achievement! Great videos of it flying on you tube now.

Great looking model but registration letters normally go under the left wing........

This however may not have applied in the good old days, still think they are a bit OTT though.
