Hey Wes,
I did not glue the cabine struts in place. They slide in very nicely and after the upper wing is installed they are captive. There is no way they are ever coming loose or falling out.

You are being too modest.
That video is superb and most enjoyable to watch.
Big CONGRATULATIONS.

My build was on hold for several months. Graduations, weddings; stuff. I re-started earlier this month. The actual build part is complete, I'm now in the process of assembly. I had all kinds of fun fitting the wing cabanes(?) on. They were off by 1/4 inch plus each time I adjusted with shims etc. I finally disconnected the main cabanes and installed and soldered the wing cabanes. I then re-tightened the mains. All came out well.
I'm now installing the servos in the wings, and dry fitting the ailerons. Next step will be to sand everything and begin covering the wings.
I've upgraded my radio equipment to the Futaba 8 FGA Super 2.4. That will be installed in the next month.
Anyway, Thanks for thought. I hope to have her in the air in a few months.

I completely understand. My build went on hold several times due to similar issues. In fact, I have barely flown anything this entire year, and have yet to maiden my pup. Every once in a while I go down and make an addition or update to my pup. I just replaced the cockpit combing (sp?) with actual leather and stitching. That came out nicely and added a lot to the model's appearance. I'm actually afraid to fly it given the time I've put in. My flying skills need improving.

Another builder
I've just joined the BUSA Sopwith Pup club, a 1/4 scale one. I bought it "new" on eBay, including the aluminum cowl, decal set, Vickers gun, and DuBor wheels. I'm very excited.
I don't know when I'll start it, as I've been interested in R/C for over 35 years I've never flown one; I have a kit I started back then that I'm completing, and have purchased a trainer. Once the old kit is done I'll start the Pup.
I'd like to incorporate quite a bit of scale detail and realism to this build. I wonder how many have pursued a fine scale rendition of this kit? I love what I have been able to glean from his web page of Mike Reeve's 1/4 scale Pup, especially the working scale rigging (and quick assembly). Has anyone bashed the BUSA kit with reference to the Reeve's plans?
How about scale under-camber in the wings? I'm also very interested in a realistic dummy motor. I have a home machine shop and some skill, so I might be able to do something cool here.
I have a million questions, yes. I've read this entire thread and am thoroughly impressed with the builds represented here, and the people building and participating in this thread: thank you!
Regards,
jv

Hello JV,
I think you will enjoy this kit. I would not consider this kit to be truly scale by any means, but if you're willing to make some changes, you can incorporate some nice scale details. It is a good kit.

Thanks, guys, for welcoming me to the forum and thread. I am very excited. I know the BUSA kit is not intended to be a fine scale kit, but i hope to build a good, rugged, flyable sport scale Pup with some nice scale details. I love the leather cockpit coaming detail. I'm thinking of a good dummy engine, realistic, functioning-bungee landing gear, simulated rib stitching and taping, lacing, cables for control surfaces, etc.
I love reading about how folks depart from the "straight" kit build and add customizations, details, enhancements.
Thanks,,
jv

JV, Enjoy the build and keep us updated with pictures and all. I'm sure you've checked out ALO 111's build and pictures. The cockpit and fabric stitching is incredible! Also take a look at Chevelle's landing gear! Very nice! There are some truly gifted craftsmen on this thread. Everything from soldering to painting! Everyone is very helpful with any kind of question. It's fun to watch each build progress. The thread has been quiet lately, so glad you jumped in with a new build.

Thanks Kevin. Yes, I enjoyed the soldering discussion. My dad was a highly skilled metalworker, a sheet metal spinner, and taught me to solder when I was 10 or so. I had no trouble soldering a cabane assembly when I was 20, but I must admit I had 10 years experience by that time! I will go back and study the details.
Thanks,

Hi Wes,
I mixed in a bit of minwax 'Mission Oak' into 'Red Mahogany' to match the color on the Xoar Scimitar (dark colored) propeller (kind of anal, huh?) I then lightly misted the first 2 coats of clear sealer using Monokote clear gloss so it wouldn't dissolve the stain. If you put it on too heavy, it will dissolve and curl the stain. I then finished with a couple of heavier coats to fuel-proof the wood. Did the same for all the wood. I found the leather from Tandy Leather along with a small spool of braided sinew. The leather came in a 8x11 piece, fairly thin and easy to work with. However, I looked on the site and couldn't find it in the darker color. It is referred to as "tooling leather". I think I paid around $13 for the leather, and about $5 for the small spool of sinew for the stitching. I used fuel tubing around the cockpit like the kit recommends, and wrapped with the leather and stitched. Drilling all of the holes for the stitching (about 57) took a little time.

Great reply, thanks. It reminded me a bit of my mother-in-laws recipe's; a pinch of this and a dash of that. I will probably do the cockpit detail, but not just yet. I want to fly her first.
Thank again. I'll post a picture when I start staining and covering in about a week.

Thinking of an engine, and a dummy engine for this. Has anyone considered (or used) the NGH GF38 four-stroke gas engine for this?
And any ideas on a good dummy Le Rhone are appreciated. On these dummies, is anyone spinning them with the prop, per the prototype?
Thanks,
jv

BUSA Pup Kit Arrives!
Got it Saturday. I've never had a kit this big, and I had a silly grin on my face for an hour or more as I went through the stuff. The package I purchased included the aluminum cowl, DuBro wheels, Vickers gun kit, and vinyl decal set. I kept thinking, "wow, this is big!"
I've gone over the plans sheets some, and read the assembly manual. This is going to require some thought to get it per the designers intention. The manual is O.K., but I found some inconsistencies: on the upper wing panel build there are some views of the left panel (e.g., photo 24), while it is the right panel that is supposed to be illustrated; in addition it seems some pics are swapped, out of sequence. For example, photo 14 on p. 8 and photo 15 on p. 9 appear swapped. Not a lot of detail is provided on adding scale details, it's a pretty bare-bones manual.
The gun kit is pretty basic - cardboard tube, bits of dowel and a sheet of laser-cut parts. I'm thinking the Williams Brothers kit would provide much more scale detail, and is much less expensive.
I'd determined to decide on how much scale detail to put in, and modify or augment the plans and source the parts before I start.
