Hi

Awesome job.
If fuse is made of plywood and balsa, I think wings and stab should be done also. Very easy to cut and build.
Shipping will be cheap in a little box.

I'm glad to see there's so much interest for a kit. Anyway, first things first: for now, my goal is to produce a model that flies well, makes weight, it's cheap and not that hard to assemble.
Papaone, i always had foam core wings in mind, but your idea makes perfect sense I'd like to try a few things though (swept wings, anhedral stabs, etc.) before deciding about the final design. Congratulations for your design, Harmonie is an awesome plane.

COOL! ....NE VEDEM LA 3 DRUMURI!

Time for an update:
The new carbon laminated firewall is quite stiff and i decided to use it. I also assembled the fin and added the formers for the belly and top of the fuselage. The stringers and balsa skin are next.

Hi Alex

I love this building. I want to buy a kit.

NB : I see steering wheel with your PC. I play Rfactor a great race simulation. Which simulation do you play ?

Hi Claude,

I would love to send you a kit, but first i want to make sure i can produce something that you will be happy with. There's a lot left to do, even before finishing the prototype, and i also have a small list of modifications that will make the building easier.

I played racing sims since Grand Prix Legends was released, and of course rFactor too. I usually play CART/Indycar or LM prototype mods, but unfortunately i didn't have time for this lately. I know the virtualr web site and i check it almost daily.
Thanks.

GO ALEX !
This is really nice !!

It finally starts to look like a plane...
I started working on the rudder, but it's not finished yet. The fin was glued to the fuselage using a laser level tool for alignment.
I added the stringers on the top and bottom of the fuselage and took a few pictures with the cowling and canopy mold plugs to get an idea of the general shape and dimensions.

That is just TOO KEWL!!!!!! Very nice!

Excellent job !!!!

looks awesome....

After a 2 weeks forced break, i finally found a couple of days to work on the model. I added the balsa skin to the top of the fuselage and took a few pictures to show the progress.

The wing tube, adjustable stab kit and incidence adjusters arrived yesterday but the stab tube is aluminium and seems very heavy. I'll replace it with a carbon tube but i need to make some sleeves for it. Fortunately the wing carbon tube and incidence adjusters are a perfect fit.

Wish I have your skill, can't wait to see the finished masterpiece ...

Hi Alex

Have you some news about your awesome building ?
Please what is the largest dimension of wideness of fuse ?
Claude

Hi Claude,

At the moment i am only able to work during weekends, which makes the progress a little bit slow.
Anyway, sheeting the fuselage with balsa is a tedious job and i think it took longer then assembling all the lasecut parts. I tried different techniques, like planking (covering with narrow balsa strips) and bending balsa with water just to see which one works best. Pictures will follow in a week or two.

The fuselage is 160mm wide and 345mm tall, but i've been playing with a slightly different canopy shape that will reduce the height of the fuselage to 338mm. The rudder is about 400mm tall.

It's finally time for some progress shots.

I added the battery tray and some balsa reinforcements for the main gear support. There's enough room in the front compartment even for 12s 5000 mAh batteries and i attached a few images showing the inside of the front section. I'm not sure how many G's our pattern models are pulling, but at -10g there will be almost 15 Kg pulling the battery tray, so i added lots of balsa reinforcements underneath.

I decided to use Radiosouth 1/4 scale CA hinges and they arrived a few days ago, so i took a couple of evenings to finish the rudder. I also attached a picture showing the new canopy shape. It's a little less tall and more integrated into the shape of the fuselage.

any more news, I'm very interested in this

I was just going to post an update today.
I've been busy working on the cowling lately and it took some time, but with some help from a good friend everything went well. First i had to finish the CAD model of the cowling by adding the lateral air intakes and making sure their shape will help extraction from the mold. The mold plug plywood structure was filled with depron blocks, sanded to shape and glassed. The next step was adding the lateral air intakes and smooth the edges with automotive body filler. Everything was finally sprayed with gelcoat and sanded again. The mold construction is classic, so i won't go into details.
I attached a few pictures showing the main steps for the mold plug, the finished mold and the final part as extracted from the mold.

Magnificent work!

Amazing work, makes me want to get back into 3D design.

could you recommend any programs to start out with

your model really reminds me of the Hyperion Helios but with more grunt and sexiness behind it.

I,d love to see you kit this design.

Wow, big thumbs-up.

From all CAD software i worked with (and i've used quite a few) i think Solidworks is the the most intuitive and easy to use. I taught a friend of mine a few tricks and in about an hour he was able to design basic parts and assemblies.

Work on the model continues, and the canopy mold is finally done. I also designed and lasercut a frame and attached it to the fiberglass canopy. It still needs some work to make sure it fits perfectly, but it's not bad so far. I'm waiting for the CF landing gear to arrive and i also ordered 25g/m2 fiberglass cloth for glassing the fuselage.

beautiful job.....

but why did you select the airfoil you used??
