The Big Nasty is an Aerobatic 3D Type model, built with Fan Fold Foam

It's on RC Groups, and our very own Ashta has also built it with a Corro Fuse and Foam wing.

Used 3 mm Corro

37" Span, 35" long, 8"Chord + 2" Aileron

Expected weight with 2200 mAh 750 gms.

Is it a profile plane?

Wait and see

Corro does not have the structural strength, being anisotropic, to build a profile. It's bending resistance is poor unless a structure is created

Wing

Balsa Spar?

Build contd...

L/G built out of 3 mm spring steel wire

Used a 2826-1400 motor. Will use a 9*47 SF prop. That's all I have 

Ideally would have preferred a 200~250 W motor, about 800-1000 KV, capable of swinging an 11 X 4.5 or so prop

Small and cute. 
Neither big nor nasty.

Why, thank you Iyer sir 

What do you suggest for the powertrain? I'm not too happy with a 1400 KV motor. The other option I have is a HK Donkey motor, about 1050 gm thrust, @ 730 KV. Maybe use an 11*6 or something???

Come on sir, Its a 3D. Get it beefed up!...

Nice build. I would love to see it in a red-blue colour scheme

@sanjayrai55 sir,
That 2826-10 1400 kv is 205 watts. 3s 7x4, 2s 9x4.7
780gms thrust.
Not enough?
What is the weight with servos but without motor, prop, esc and battery?

I have a new 2830 1000kv, 210 watts, 10x7 on 2s, 8x4 on 4s, 890gms thrust claimed.
Also have a DYS 2836 1120kv which is about 300 watts.
If you need either, will send.
Regards.

Sir where do you get these amazing corro sheets from,tried searching alot but couldnt find any sellers around delhi.
Ps - amazing build sir,you are like the "shatabdi",so fast and quick :p

We people are like goods train . Always shatabdi  and rajdhani gets the signal. Iyer sir is like rajdhani express.

Iyer sir, I have managed a 2836-1100 KV. Plan to use that with an 11*5.5 E Prop

Right now working on the controls - need about 45 degrees travel on the surfaces. Will put the control surface side of the pushrod in the bottom hole of the horn; may have to extend the servo arms (How  )

Using a servo arm radius of 1.5 times the control horn radius should do the trick.

Will use a different design of Horn - an adjustable height horn 

Where did you get that sir?

Bought it from HK about 6-8 months ago. Had some few grams left in postage limit, and thought that maybe some day they would be useful
