I started with that same frame. Its a tight frame to work on. No way you'll get that 30 x 30 AKK VTX to fit.

I would suggest this frame (no personal experience, yet): https://www.amazon.com/iFlight-Cidora-Squish-Freestyle-Carbon/dp/B07W6L249N/ref=sr_1_4?crid=1BSSAVGTQ97E3&keywords=iflight+frame&qid=1573651923&sprefix=iflight%2Caps%2C165&sr=8-4

If you stick with the Rooster clone, then you will need a VTX like this: https://www.amazon.com/AKK-X2-Ultimate-Switchable-Compatible-Configuring/dp/B07DPG5H1T/ref=sr_1_6?keywords=fpv+vtx&qid=1573652145&sr=8-6 Its what i currently have in mine.

I would also change the FC to the Matek that was also mentioned.

The RunCam Eagle is full size and will fit.

The rest looks good.
