Graff Posted April 13 Share Posted April 13 Hi all, I have this 1/4 scale Sopwith pup, built from a DB kit back in 2000... I bought another Pup the other day that was sold as a DB 1/4 scale Pup. But when I put them together, the size difference is huge... Here is my old one in front: Okay.... Then we have the wings: The new one is smaller, but the wingspan isn't much shorter.... The cowling of the old one compared with the new: You can also see the wheels. So, what gives? The big one is mostly correct when the judges compared the three views of it (except the cowling, which is being replaced with the short lose one). I can't see how two DB models can be so different, so the new model is obviously something else. But what? Thanks. Quote Link to comment Share on other sites More sharing options...
David Ovenden Posted April 13 Share Posted April 13 David Boddington designed very many models, He did a 1/5th scale plan for the Sopwith Pup. Maybe the new model you have is 1/5 rather than 1/4 scale? Quote Link to comment Share on other sites More sharing options...

dave parnham Posted April 14 Share Posted April 14 (edited) The Green topped one looks like a Flair kit to me. The puppeteer? Edited April 14 by dave parnham 1 Quote Link to comment Share on other sites More sharing options...

Geoff S Posted April 14 Share Posted April 14 The 60" ws DB Sopwith Pup is a fairly new offering. I think I had one of the first kits in late 2019. Mine is ready to fly now but remains earthbound so far. As you can see the cowl is very short. The wingspan is pretty well exactly 60" as it says 'on the tin'. 1 Quote Link to comment Share on other sites More sharing options...
RottenRow Posted April 14 Share Posted April 14 Balsa USA make a quarter scale Pup kit, that has a fuselage length of 53”, a 77” wingspan and a wing chord of 14 3/4”. Could it be one of those? Can you see inside it whether it looks to have been built from a kit (printed numbers on parts perhaps?). Brian. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted April 14 Share Posted April 14 The full-size Pup wingspan is 26'6", so a quarter scale Pup should have wings 79.5" long. It seems odd that the Balsa USA 1/4 scale Pup has wings that are 2.5" too short for true scale. Quote Link to comment Share on other sites More sharing options...
RottenRow Posted April 14 Share Posted April 14 That’s the information given on the BUSA website. Their models, like DB’s, are sport scale so some liberties may have been taken. One possibility is to allow the use of standard 36” wood for the spars, leading and trailing edges etc. Just a guess… I just looked up the DB model on their website, and that is 77” wingspan too! Mick Reeves’ accurate quarter scale Pup has a wingspan of 79 1/2”. Brian. 1 Quote Link to comment Share on other sites More sharing options...
Geoff S Posted April 14 Share Posted April 14 I'm more likely to believe a Mick Reeves model to be true scale than just about anyone else, so it looks like there a few Pup kits around that are near scale only. Not that it bothers me - I'm happy with sport-scale for my own models 🙂 There's a lot to be said for adjustments that allow wood economy without totally spoiling the scale look.
