Thrust to weight 1.1 to 1,

So it looks like I can shave quite a bit of weight of by not having that hulking great 5S in there ...

Looking in my spares box - I only have a 3530 1100kv so :

I then entered 1.2kg
3S 3000
50A ESC
TGY 3530 1100kv
APC 10x6
=
11mins
257W
1.09 to 1

If I up to a 4S and drop prop back ...

1.2kg
4S 3000
50A ESC
3530 1100kv
APC 8x6
=
13mins
309W
1.2 to 1

VERY INTERESTING !!

The question then remains about launching ... looks like maybe need to look at retracts being fitted t avoid the hand launch scenario - its a big model and no way for own to do it - must be second person. Or a 'dolly'
Hi Nigel Use a 8x8 APC Prop on 3 or 4 cells, it will be powered very close to a V900
