Don't wake a Tiger until you've factored the teeth




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.

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

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 Sad

Why, thank you Iyer sir  Salute

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???

@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.

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  Head Scratching Head Scratching Huh?)

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