The Kore build is an extremely tough build, the parts only just fit so you have to choose wisely what you want to put into this build from the start.
Its a good idea to watch what items we have chosen, and try to keep your stacks to a minimum of 2.

The best motors for this frame are a mid range KV, around the 2500KV mark.
You will find that the aero on the frame slips smoothly through the air so it tends to go.... ALOT faster than other frames so those higher Kv's above 2600+ you will find a little insane.

We Chose again, and as usual the AIO but modified it for 5S performance (We will update this later to show you how but at your own risk)
We also recommend to use the "Stubby" AIO because the width inside is tight. We did fit the standard size in there but again recommend the stubby for an easier fit.

For the VTX, try and use a Unify PRO so you can change the channel and band from your OSD or if your using a rush V1.1 put it upside down so you can see the numbers from the hole cut under the battery strap.

You can also use a Suncam Split if your using the Kamikaze AIO, so you only have 2 stacks in the board.
