Thank you for the kind words. I wasn't sure when I was building it how it would actually run on the water, but I was pleasantly surprised how it easily planes and rides level in the water.
Very nice, she looks great on the water. I've been wanting to build one myself for a long time, been waiting for a time I can fit it in my budget but lately that seems to be getting even harder.
the Dumas website has sales all the time. Set up and account and you will get notices when they have discounted sets. sometimes they discounts sets as much as 40% off.
Roy, your video is the best one out there. Can you tell me if you used any filler and what was it, if you did, Also, did you use a stain and what was it, I'm thinking mimwax cherry. I've returned to your video many times, its been a great help. Craig
Thank you for the kind words Craig. I did not use any filler or stain. The mahogany wood darkened up when the epoxy was applied, and if you pull and glue the planks tightly together, no filler is needed. The planks are about 3/16" thick, so you sand all the planks down until they are smooth, rather than fill the low spots.
I am not sure if the white skin is called depron? It is very rigid like 1/8" plastic. It and the ribbed frame really do give the boat its strength and shape. The Mahogany wood is simply for looks and does not add any strength to the boat.
Jagitmax: Good Question! So actually it only takes 3 perfect coats to look great. The problem is that I do not have a spray booth. Each time I put on a lacquer coat, a nat or bug would fly into it. So I would sand it out and shoot it again. One time I accidentally touched the fresh lacquer coat with my hairy arm. One coat I actually dropped the entire boat on my shop floor. So when I say 11 coats of lacquer, it because it took me 11 try’s to get a coat without some unintended inclusion in it. Also I realized as soon as I was finished I was going to put it in a body of water with duck crap in it. So I got it as shinny as I could given it was for use and not display. Thanks for your comment!
Yes it is a Dumas kit. I cannot say enough great things about Dumas! The kit was complete with quality cut parts and very descriptive and understandable directions. It was really a joy to build.
Only from people such as myself that build them and resell them. There are no Dumas pre built Boats with RC installed and ready to go. I would be happy to sell you the one I built in the video. Email me directly at royyaredsemail@gmail.com for details. Thank you for your service!!
@@royyared8218 I'm not familiar with Dumas boats but would like to know the cost and lead time to purchase one (1) you have built. I appreciate your quick response.
I used CA glue with a drying accelerator for the planking and almost everywhere else. The CA glue comes in normal, thick, or extra thick for different situations. In areas that need extra strengthening like the hull frame, I used 5 minute epoxy. In the video you can see the different glue bottles used off to the side on the work bench.
@@royyared8218 I have a og not built still in box Berkeley Chris craft Cobra 31 inches with gas engine servos everything except fuel tank.. not sure what it's worth being the first ever in 1955.. also have original poster for it when it went for sale back in 55.. like to find someone to built this and buy it from me
@@aaronbrown4340 I am not sure where you are located, but if you mail it to me, I will build it. We can agree on the details off line. I will return it to you after building it. I am not interested in buying it for myself.
Mark Hensley; I would go to the Dumas boats website. They sell replacement parts for that boat. You can order a motor and speed controller, and you said you already upgraded your battery. I would buy the most powerful motor that they offer for that boat. That should do the trick.
Roy, thank you for your video… very good overview! I inherited a 1/8 scale CC Cobra model built many years ago by father in-law. It’s one of my most valued possessions. It is fitted for RC, but components are old and the boat is very slow. I’ve upgraded the battery, but I suspect it could benefit from a more powerful motor. Any recommendations for a newbie?
That really is a nice boat. I like the short teaser video's too. They are indeed real teasers - makes you want to see more! 👍
Thank You for your nice comment!
Wow ! That is a great job you did there Roy ! Looks very realistic , and goes well in the water too.
👍Wonderful.

Beautiful boat. Great video 👍

Top job Roy. Would epoxy have been an option instead of Lacquer. Asking because Im build something like this soon.
Nice job Roy .looks like fun.CHOW FOR NOW
Thank you very much!

Great video thank you. Is the hull skinned with depron first?

“Sintra” is the name Dumas use
Where did you buy the plans for this boat
Dumasproducts.com They have kits for just the boat, or everything to be ready to run(RC, Motor, battery and charger...)
@@royyared8218 that’s awesome I’ll have to check it out thank you so much for letting me know!
After watching you apply all the coats of lacquer, why didnt you rub it out until it was glass smooth?

Roughly how many hours to build? I've built an RC boat before but never a Dumas kit.
Is this using the recommended Dumas motor?
Roughly 100 hours. It's all 1 hour here and 2 hours there. A lot of waiting for glue to dry.
Is that the Dumas model? I've built that model. Very nice.
Yes it is a Dumas kit. I cannot say enough great things about Dumas! The kit was complete with quality cut parts and very descriptive and understandable directions. It was really a joy to build.
I am a totally and permanently disabled Vietnam vet and could never build one of these. Can I purchase one already built?

Go brushless. Dynamite 2000kv 4 pole motor with a 60 amp ESC
Thank You!
How could I have made this video better/more interesting?
Roy, thank you for your video… very good overview! I inherited a 1/8 scale CC Cobra model built many years ago by father in-law. It’s one of my most valued possessions.

by showing the process with commentary instead of potos :)
Greg Wagner: Im shy and not the most articulate. I will stick to pictures and videos of the boat and process. But thank you for your comment.
