This is my first build for the sixth sweepstakes.

Model is 1/2 A size PAPILLON recommended Engine Size is 0.049 to 0.074

Had a lot of Balsa and lite ply scrap lying around left over from my all previous build so decided to build one more for my Thunder tiger GP07 0.07 size using all the scrap wood available.

Plan is from http://my.pclink.com/~dfritzke/papillon.pdf

Formalities

In the plan there is no aileron planned. However I am planing to add them.

First thing first have to cut out 20 Nos Ribs of the wing from 1/16th of a balsa sheet pieces.

Great, Colonel Saheb 

Thanks Sanjay Sir.

Awesome!

Lovely Col....... this gives me a glimpse of the Balsa Scrap I have been collecting for some time and also from the Sharmas at Jodhpur.   Agreat model and I am sure you will make a Beauty of a model...... as always...
My best wishes and regards
Shobhit

Those Japanese plans, I swear! Me hooked on!

All the Best....
 Congratulations..!!

After a long Sabbatical once again commenced the build. The progress on the ribs.

Template on a 4mm ply                                                                         Template cut out using Dremel.

Oh ! this was what you were upto ? while i was KE pe selfie ?

More Progress.

  Looking real good

Thank you Sir.   

Is that a norwell engine? Or ap ?

Superbbbb Build Sir Ji....

Sandy is this an ARF ? 

Vishal and Jana thanks.

@ Jana it is Thunder Tiger GP 0.07.

PS : Vishal we are still waiting for the Durlab Singh  

Gusty Thanks. When finished it will be RTF for you.  

PS : hope I will find time to complete the final formalities.

Almost nearing completion.

Aileron hinging, Control rods, are balance. Target AUW was 550-650 gms. its 510 gms till now with every thing inside less 400mah lipo and fuel. Expecting finalizing at 560 gms with full tank.

Beauty! 

No LG?

Thanks Sanjay Sir,

As of now not planning it to keep it sleek in air. 

Very nice and colourful.

Sundaram sir .... Perfection personified ....

Thanks Doc. Thanks Ashok Baijal Sir .

Finally Completed and ready for test flight. Since build has been mostly  midnight to midnight I am worried I might have to do a night test flight.

Wow beautiful plane sir total cost

Wow beautiful plane sir total cost

Thanks Tanmay. Build with all the parts available with me. Need to do a BOQ to arrive at the total cost.

Balsa is mostly scrap pieces and three full new sheets of 1.5mm for the sheeting's where ever required.
Monocote is 1.5 Mtrs all colour put together.
Remaining are Engine, five servos HXT 900, control horns four, control couplings four, flexible control rod snake and tube one, fuel tank 2 ounces sulivan flex, BEC HK 3 Amps and thats about it.
 

Wingspan 43"
Chord 6.5"
AUW 585 Gms.

Wing loading 10.5 Oz/Sqft

Its a Glider alright 

Test flight in next two days.

Papillon is still to see air time and in the mean time parts for next 1/2 A is already ready. There are ribs enough for two more wings and still the scraps are no where near getting over. I thought i can throw some scrap out after cutting parts but they now seems good enough for micro scale balsa build  

It was slightly tail heavy. May be as suggested by Sanjay Sir will have to add LG after all. For the first time the TT GP 0.07 is in air so chose to keep it rich and flight was smooth and steady. Next flight I will make it optimum needle settings for the model. This completes the formalities for the Sweepstakes 2015
Enjoy



Thanks for watching

Very nice. Waiting for the next build using the precious balsa scrap.

Thanks Sir.  Yes next 1/2 A is already half ready photo update coming up shortly. That's going to be junior papillon with lesser wing span for Cox 0.049.

Can't ask for a better launch/takeoff in the maiden!
Hands off she went straight and smooth.
Sundaram sir was saying she'll be a glider.
I kept thinking she'll be a jet.
On rich needle or power off she was like a trainer.
But did you see what happened when she was leaning out?
Wait till the needle is screwed in another 90degrees...

Sir, the youngsters kept asking you for the Tx, but you never gave them 

Lovely Sandy! So stable; and, after the engine cut she floated in like a butterfly 

Thanks Iyer Sir,

It was after a really long time for the first time I could get the TT GP 0.07 in air. This was my first engine which I had bought during my novice days of aero-modelling in Oct 2009. I had actually bought it along with a 1000ml Fuel tank from towers, not really having any idea on the size of this engine I was buying   . It was only when it reached me I realized my blunder. I was just relishing the flight & engine for the moment. Further logging the video for the formalities was also a priority in back of my mind.

Next time on-wards it belongs to the Youngsters sir.  

Yes sir was really happy with the way it went off away from the hand. I flies really well.

By getting the CG little forward and the engine bit more leaned out it will perform really well and aggressively. Good 12 Mins of flight time with a 2 Oz Sullivan flex tank.

Thanks Sanjay Sir. It flew in like a well trimmed glider.

Progress on Junior Papillon   Continues

Its based on build of same plan but with less ribs

Wing Span 92 Cms 36"
Chord 6.5"
Expected AUW 450 gms Approx with a Cox 0.049.
Wing loading 9.8 Oz/ Sq ft

Going to be a glider once again.



All feathers are ready need to build the fuse now. I have to complete this soon and commence my Delta Pulse jet soon.

Some more progress on Junior Papillon.

....super neat ! not a single wrinkle I could see !

 also, a 10+ opsf plane without landing gear.....hats off !

@sundaram sir,
Pics in reply 44 showing, but not in reply 43. Odd???

@ Bhavesh thanks. Still practicing my skill for balsa build and perfecting my hand for my upcoming more ambitious Balsa builds.   my flying feild is with lush green grass now I can risk the belly landings for now.

Iyer Sir it's seen at my end both #43 and # 44. May be a refresh screen will do the trick at your PC.

Now only electronics and linkages of fuse left for the Papillon Junior. Maiden this Sunday would be lovely. Unlike the Senior Papillon, this wing has no dihedral and no sweep. It's absolutely straight and flat. Turning out to be very tail heavy as of now let's see when it's ready completely. The wings are completely interchangeable  with senior. 

Lovely Build..... would love to see it flying like a beauty....
Best Wishes Sundaram Sir.

Thank you very much Sir. Hopefully this Sunday  if all goes well.

Very nice sir , is that a electric prop on cox 049?

Waooooo!!!

Thanks Jana. That's a APC 6x4 not sure if it's electric. Will not be using it though. Will be using a Master Air Screw 5.5 x 4.

Well.... Sir,
I am not sure what differences it makes to have what prop on the motor or the engine.... I know I am not exactly right on this issue..... For all my motors I buy props from HK and I do not like the shape of APC propellers..... Have used all other types including the 9x6 / 10x6 and 12x6 Nylon and glass fiber of Sharma's.....  I am sure the cox 049 is a small engine and it would not mind the APC propeller too.... correct me if I am wrong please.

You are absolutely right there Sir. Cox works just too good with APC props as well. Makes not much difference.
Peak RPM is though better with a 5x4 Master Air Screw or the Cox soft ones same size. Props supplied by Cox sellers are softer than electric   may be the Glass filled ones would make a difference in a better designs other than cox sure starts which have peak RPM at 19000.

Papillon Junior is also ready with all electronics fitted. Engine has been run two tanks and it runs good peak RPM with 5x3 prop.

Finally ready for test flight. Now my 1/2A lot is full for the time being

Maiden of Papillon Junior. This completes formalities for the Junior too.

Very nice sir 

Thank you sir.

Junior Papillon gets an engine upgrade to ASP wasp 0.061 from the earlier Cox to keep in pace with the Senior Papillon with Thunder Tiger GP-0.07

Unused engine mount which did not fit the TT GP-0.07 came handy in the mount.

Has done two tank initial run in on ground. After two more will take it for inflight run in.

So far seems very promising.
