Watch this space for a built and fly log  of SU- 26

I have not done much headway on the above plan but I have started on a different plan of SU-26 which is a modified one with aerofoil wing with semi profile and semi fuse model of SU-26. The wing, tail plane and rudder is ready. The fuse has to be assembled and control surfaces hinged.

Did u get it bu hand or ordered on line from 3dfoamy. What all electronics would u need once built. N do they send it with electronics

The foam is  10mm sheets from EPP india.  Cut and glued with dentrite and flexquick CA normal with spar and reinforcement in place  and sanded.

Electronics I have not thought about it yet for the moment. Post details as it goes.

Thanx

The fuse is finally ready. Wing is hinged and ready. Now only they have to be put together with electronics.

I was planning for a 2217/8 Dys brushless 1100 KV with 11/5 prop 40 Amps ESC. For the power system.

Expected AUW is 750 gms.

Sundaram Sir.. waiting to see her finished.. i love your paint schemes always.. its all stunning..  :hatsoff:

Thank you Roopesh  :hatsoff:

yes Sir.. your paint schemes are awesome.. and stunning.. i always looks in to your photographs, repeatedly, and wonders especially all you making those with acrylic based paints.. flaming patterns are great to see.. thanks for sharing.. :salute: :hatsoff:

Thanks Roopesh  :)

The model is finally ready for paint job.

Looking Beautiful after completion. {:)}

thanks Manoj  :)

another fantastic build by sundaram sir!!!!!

is fuse reinforced? i could see something running from motor mount till tail?

Thanks  :thumbsup:

The fuse is reinforced with glass fiber rods on a groove with CA from both sides. Its pretty stiff now, almost like a block of wood.

Sir waiting to see yours amazing paint scheme.. (:|~ :salute:

Dear Roopesh the photos are specially for you  ;D

Finally it is ready for flight.

The Lipo is just ahead of CG. The CG is at 40% Chord  With 2217. May be good for 3D hover but have a feeling will pitch up even through the thrust line is 2 degrees down and 2 degrees to right. If found under powered was planning to switch to 3530 1400 KV. Then CG will be at 30% chord if Lipo location is not changed.

Sir beautiful colors. (:|~
Looking very beautiful. Waiting for its flight test test .

Very beautiful color scheme, other planes at your field will feel dull now :)
 :goodjob:

Thanks sunlike star and thanks manoj.

Sir..its great.. and the moment that i waited.. a million salutes for the colour schemes.. its all amazing and unmached.. like usual.. (:|~ :bow: :salute: :salute: :salute:

Thank you Roopesh you are an inspiration to many of us  :hatsoff:

Sir.. still i am looking on it.. its amazing.. just like a peacock feather..  :salute: :salute: :salute:

superb !

Wow! stunning. Will look very beautiful in the sky.

Sundaram sir,a thousand salutes. :salute: the colours are breathtaking. It's a visual delight when parked and I'm sure it will be the same when soaring high in the air. Waiting for the its flight videos. Plz do post them sir.
Cheers.

Thank you Dr Khanna,  Rohit,  Gusty sir.

Here in shillong it is so windy now a days we are also eagerly waiting for calmer days and busy building.  :)

Gusty and myself tried a hand each on the model  this wednesday. Flew well for the first time.

Did not record flight video since light condition was not good and would not have done justice to the colour scheme.

Still some tweeking needs to done with DR and Expo to arrive at a perfect setting. Gusty was confident it will do a decent 3D.

I feel since Aileron response was good so it was OK toned down but the response of rudder and elevator was not so good so it needs to be toned up a bit. Gusty I would like to know your take on that before I do anything.

Need to do a chequered pattern under wing for better orientation.

The servo arms needs to be bigger, Throw setting will requires 5-7 flights to arrive at perfect throw and expo for different manoevres, Aileron throw needs to hit 65 deg for a decent rolling harrier, Since the span is big roll rate will be less especially in a right rolling harrier. can the rudder become bigger ?

Rudder and Elevator can surely be made bigger in the present configuration without disturbing the present hinges. I will try the lengthening of servo arms like how you have done in your yak and Addiction
