-AUW weight 600grams
-Wings will be flat ,without airfoil.


Plans are from www.parkjets.com

-Big white foamy blocks
-Cut the Big foamy blocks into smaller chucks using hotwire
-I have now many smaller chucks of white foamy blocks
-Now i can start cutting out piece by piece

[viper1990]

-But i can't start cutting without the templates so..
-Draw templates on cardboard
-Cut templates out
-Pin the template on foam block
-Hot wire the shape out

[viper1990]

-Aligning the pieces that i've cut out.., looking good so far
-Can't wait to glue those pieces together to see the overall result and shape of the plane!

[viper1990]

-Cutting the ducting out from the fuse.
-Thats where the ducted fan will be placed
-100% FSA at the intake
-80% FSA at the exit
-tedious calculations and measurements are made to ensure the area smoothly decreases through out the whole tube.

[viper1990]

-Glued the both halves together now..
-Looking even better! very excited to get the whole plane done asap
-Lazy to make a transparent canopy, so i just cut one out of white foam.

[viper1990]

-Wings and tail stab are made of blue foam
-Glued to the fuse and reinforced the joins to reduce wing flex

Alright,heres the end product! Sprayed with nippon paint silver colour. Yes..nippon paint, those that eat foams up. The reason why it didn't eat into mine because i applied a layer of protection before spraying it. (and that is also why you can see wrinkles all over the plane which is not really nice) Hmm..., not the best mirage2000 out there, but i'll practise further, improving my finishing!

Now..., the fun part, to get this plane up up in the sky! Zoom zoom!.... Will update again when i manage to find time to fly it.

What kind of protection u used?

Wah beautiful..... Want to see it fly...

Well done. can I come to your place to learn from you how to cut and glue and the fixing up?

I don't really have time nowadays to do teaching , don't have time for myself to build planes recently or go down to flying field, having my school industrial training program now. I can do online teaching though ^_^. Simple for me. Any questions for me just ask away!

Ok..so to jieZ's question. The layer i put on is something like a tissue paper (no not those found in toilets) , Its those found in artfriend for arts & craft, very much like fibre glassing , but its thin paper and whiteglue instead of epoxy resin and fibreglass. It dosen't add any strength nor weight. Its just a foam protection... see picture and you'll get what i meant.

Anyway, Today was the madien day! went to school to fly and it went up up and away during the first toss!
-It wasn't fast at all
-very sensitive when fast
-stable when slow
-Barrel rolls were incredibly quick
-can do high alpha at a very large AOA without stalling
-and it's somewhat satisfying to fly
mission accomplished

Congrat on your sucessful maiden.Reminds me of my previous M2000

Dude,
Next Time Tamiya Spray paint.

Brilliant work Viper!

Maybe you don't have enough time to finish up your plane, but you should consider spending more time filling up the rough surface and finishing your planes.

To save money you might want to use water soluble emulsion paints like I did for my Tucano

Keep building!

Cheers!
