Specs:

Wingspan   50 in   1270 mm
Wing Area   540 sq in   34.8 dm²
Length   47 in   1194 mm
Flying Weight   5.5 - 6 lb   2500 - 2720g
Wing Loading   23 - 25 oz/sq ft   70 -76 g/dm²
Radio Required   4-Channel (not included)
Engine Required   2-Stroke .40 - .60 (6.5 - 10 cc) (not included)

I got the 3 plastic parts - Turtle Deck, Canopy, Cowl from USA. Rest is scratch built here

The wing is foam core with balsa sheeting. Cores were cut with hot wire

LE & TE from 6 mm balsa

This model is being built without plans!

Working with the build manual, and some photos/details found on RC Universe

Wing sections joined



Centre portion reinforced with Glass & Araldite

Fuse started

Fuselage is in Corro, wings are foam with 1.5 mm balsa sheeting, and tail feathers are 6 mm Balsa

Looking neat and great sir!!

Thanks Mehul. Still a long way to go!

I considered using 3 mm balsa sheeting for the fuselage. But after some consideration, I realised it would add about 150 grams, a lot more work, and Corro would work fine

Plus, if I don't use some corro, it would be OoC 

What is OOC? 
Great build sir!

Haha.
Try to guess.
Here’s a clue. “It has reference to the context”

As soon as I saw Rai saheb’s post, I began waiting to see who would be the first of many puzzled members to seek clarification

Lol Iyer sir! Prabal, OoC is "Out of Character"

Wing is held down by dowels in front, and bolts at the back. Before gluing in the formers I fixed the Dowels, as later there would be no place for the drill once the fuse was assembled

another beautiful creation by sanjay sir

Fuselage assembly

Thanks Gaurang 

Sir don't you have many planes, making harder to store more??

Lol

Actually I give away lots to friends

Ooh great for them.
What about hangar rash??

A part of life

Not dependent so much on quantity of models, but on how they are stored, and how long they remain idle without being flown

Need to make a balsa piece for the lower fuselage front.

Supposed to be carved out of a 1"block, I fabricated one instead by gluing strips

Fuelproofing. Ordinary enamel paint

Wing tips made

Original design suggested carve out of a 1 1/2"X 1 1/2"square bock. I chose to make a fabricated (built-up) tip

Sanded and fitted ailerons

The wing is 51"span, with a sweep-back, 12"chord at the centre

I had inserted hardwood blocks into the foam before sheeting, for anchoring the main LG

Aileron Servos. Made a 3 mm balsa box, with a 3 mm ply lid, screwed down.

Drilled a hole through the foam, and put a PVC tube, for the aileron wire

How did the elevator and rudder become shiny white from brown??
I also don't see control surfaces on the trail.

They were covered with heat shrink film(generically Monokote)

The Rudder & Elevator are yet to be fitted on

What are the control surfaces made of??

Same, balsa covered with heat shrink covering film

Coming along beautifully sir!!

Thanks Prabal

i love that finish!!

Guruji,
Baki sub chodo.
Yeh cowl kaise banaya?

Iyer sir, I bought it ready made! I bought the 3 plastic parts, Cowl, Cockpit canopy & turtle deck from Sig Mfg.

Then trimmed and painted

Just beautiful.....expert craftsmanship !!

Thank you.

Me want that sexy plane!
Kudos sir!
Waiting until march to get back up in the air with you people. I really miss flying a lot!

March isn't far. Study hard now, and post exams the flying will be that much sweeter 

Some more

Am I the only one who is wishing to build something amazing like that??

 

Start with something simple and work your way up

I know sir!
Will you help me make a scout 15?
Maybe i could come over to your place (again) ? 

Sure

Some colour trim

Assembled

Wow!
I’d sure be scared to test fly this.
Though I’d have tried if it’d been control line... 

Why ever? Is something wrong with the build which has slipped my attention?

Sent from my Moto G (4) using Tapatalk

Not at all!
Just looks too fast and fighter like for my skill level (electrics below 300 watts, except for one 40 high wing)
Haven’t had the gumption to assemble the Cap 232-46, or to complete the Minare!
Perhaps I should try my hand at precision aerobatics before I get TOO old...

And btw, my control liners were all Enya 19/ OS 20 powered.
I once bought (for 500) a 35 stunter from Mr Nagar, (engine and lines borrowed from him)
But after just one flight, and the line tension really scared me.
So I returned it. He said once sold is sold, can’t return the money.
But he was kind enough to give me an old Merco 35 in exchange.
I still have it some 40 years later, though the carb mounting screws are nowhere to be seen...

Hope you did the maiden flight today (being Sunday). Await video eagerly.

Here’s what a 50+ year old Merco 35 looks like...

Which Mr. Nagar was that: Vijendra or Ajit?

I rather trust Sig's designs, and hope the slow flying characteristics will live up to expectations

I myself am too old and short-sighted to try any precision aerobatics. I just enjoy building, then the unsurpassed satisfaction of seeing your creation fly 😁

Planning to maiden this coming Sunday

Shortly after this I tip-stalled and crashed. Was flying too slow

Sent from my Moto G (4) using Tapatalk

Can't believe I missed this beauty. Wonderful build sir.

Nitesh.

 

Sorry about the crash.
Repairable I hope.

Iyer sir, I'm going to try repair. Otherwise will build a new fuse, which luckily is Corro

Sir,
When are we going to see it in the air again?

Soon! 

Repairs done, just waiting for better weather

@sanjayrai55 sir,
Good to hear she’s repaired.
Patch up or new fuselage?
Hope cowl, canopy etc salvaged.

Best wishes for next Sunday. BTW, what’s the span, and wing loading?

Regards

Sig Kougar looks great...classic sIg design. Hope to see it flying again. So are you using the Merco?

Iyer sir!

I've completed the repair, but due to some rough patches on the ruway, won't be flying it till the end of the month. Will post some repaired pics soon

Thanks Suman. I don't own a Merco, as mentioned earlier am using an OS 46 AX II

Repaired

All of got to say is that it looks absolutely Gorgeous!
Kudos Sanjay Sir!
If I am not wrong, this is a pattern aircraft?
