The fit of the parts is good, the plans are.good but perhaps a bit confusing for beginners, the quality of the wood is vauge, you'll get two sheets of ribs maybe one is soft one is hard but by and large if you take your time and think ahead you should end up with something that looks nice and flys reasonably well.
I have built one too, for gas free flight, with an .010 that's a screamer, but doesn't do any good because the 3.5" prop they run on won't clear sream over the big cowling. I don't think you ever need to worry about losing this ship in a thermal! I made my wheels and pants out of balsa also. I'm going to have to buy a tiny diesel so I can swing a 6"x3" prop to pull around the cowl. Like a Bambi, .015. I'm used to diesels and they make the best power for FFscale airplanes. Good vid, and good luck on testing.
Right away I saw that this Dumas kit was intelligently designed or lightness which is the key to good flight in a model of this kind. The structure of the fuselage looks very light, but also as strong as it needs to be, which is not very. I would laminate balsa strips for the tail surfaces instead of the laser-cut, too heavy bits from the kit, or at least thin them out a lot. I would also cut out much of the rib's interior wood and sand them thinner to save lot of weight. Those blown plastic bits are a PIA in every kit that uses them and I sympathies with your having had to deal with them. Still, they are very light and look great when, after a lot of fiddling and frustration, they are finally finished. Great build. I see you used the historic "John Deer" paint scheme. A nod to farmers, I suppose. Just beautiful. Are you going to fly it? I always regard installing a de-thermalizer on a model of his kind as being charmingly optimistic. I hope ii flies so well that it de-thermalizers as intended and saves the model from that super thermal it found. :D
Thank you for your comment, yes I will fly it, the weather is here now although it has been very windy recently. Charmingly optimistic which is a nice way of saying un necessary, probably right given the single loop rubber motor, I don't think it'll be an endurance flyer more like a pheasant, a short fluttering burst of power, whatever, it'll be fun..
The quality of the wood is good but variable some sheets are soft some are harder when you get ribs cut from both it kinda suggests that not much grading took place at the laser cutting facility.
@@MachineElf You would think that, cosidereing what these manufacturers charge for their kits, they would use the best balsa. Guillows is the same way. They can't use die cutting as an excuse anymore to use heavy balsa. Even their laser cut kits come with heavy balsa. It seems to be hit or miss with them. For example, if you buy one of their 900 series kits because you want a light weight flyer, you might get fuselage sides that seem like they were made out of bass wood. Sometimes not. There is no expectation of consistency.
Sorry could not get past the music
What did you think of the Dumas kit in general? I have one waiting in the wings. btw, awesome build.

Nice
That's a fantastic build ,nicely done.

What did you use to cover the tissue? -- It looks great!
Thank you for your comment, the tissue was applied with thinned pva glue,
water shrunk then a thin coat of clear shrinking dope sprayed on..

@@MachineElf And fun is why we do this.
Good luck, mate.
You should do a dedicated video on how to do the dethermaliser! That it some bit of engineering!
Thank you for your suggestion, I may do a bit about it when I do the flight videos..
@@MachineElf alright, awesome!
Does Dumas still use high density balsa?
The quality of the wood is good but variable some sheets are soft some are harder
when you get ribs cut from both it kinda suggests that not much grading took place
at the laser cutting facility.

Great Job! Getting it to weigh 102 grams, is a good accomplishment. Can't wait to see flight videos!
That’s a beautiful build. You must be pleased with that !
Thank you for your comment, yes, both this and the Bulldog model turned out very nicely
and I'm pleased with the results.
excellent build!
beautiful job… BRAVO
Thank you,
I will, one day, endeavour to make a flight video but motorcycling has me in its grip currently.
Nice job, looking forward to seeing it fly.
Thank you.
I assume it never flew. it takes talent to fly well, any one can build and hang it up to look at.
