Firstly, is the firmware? Is it already on the programmer or esc? If not how do i get it there? I have downloaded the USB Link V1.63. I believe i want the V211 firmware in the esc and 110119 in the programmer? Is there and absolute idiot guide to getting these on there?

Go into your software in your PC, update your 2 in 1, by selecting 2 in 1 under the Device tab at the top. After updating your software version of your 2 in 1 should show V1.07_110119.
Then connect your esc to your 2 in 1. Select ESC under Device, under Software tab, go to drop down under Choice Version, you should see V3.0_110211STOCK. Select then click upgrade.
The pdf guide has recommendations for your motor turns, start from there ...

hope this helps ...
