Please help. This is my first build and I thought I was doing so well. I put all the details in ecalc which says I should have a thrust of 3.4 but it will simply not leave the ground. Please see below for my build:
CC3D with Libreflight
4 x RCTimer SL2212 920 KV
30 A ESC RCTimer BLHeli
5000mah 30c
Prop Gemfan 1245
Span 600mm
Total weight 1300 grams

I have been through the set numerous times and the motors are rotating correctly.

Attached are images of my build,

Where am I going wrong???

Hi mate it looks as the props are on wrong the set up is
Front left CW front right CCW
Rear left CCW and rear right CW
An easy way to remember it is the front 2 motors answer props turn towards each other the back 2 away from each other
In photo one if that is front marked on the frame then motor 2 prop is wrong that's a CW prop.this may help I did this video a long time back

 
Holtneil is correct. It should be like this.

Hi Ringalong the pic you posted has the motor numbered different most common quad is
front left motor 1 front right motor 2
rear left motor 4 rear right motor 3
but as you say the same props on 1 and 3 and 2 and 4
 
Thank you so much. You are right - rookie mistake. Enabled me to have my first crash and I mean that in a very appreciative way.

The other piece of great advice I have had is make spares and use cable ties which I have done and this allowed me to get straight back out there.

Thanks again guys.
