Speed Addict 210, Littlebee 30, Naze 32, excellent choices. I can't speak for Cobra motors but I suggest higher Kv and 2205 for balance between torque & rpm. Xnova, Scorpion and Zoe daily performance are all good options. I've seen Xnova & Scorpion in action and both are powerful tipping in favor of Xnova. I haven't seen Zoe but I know who started Zoe and he wouldn't release a poor quality product and he would make it right if you have a problem. I will be upgrading to Zoe 2205 2550kv motors for my Race Spec build.
Pulse lipos are reliable with several options available.
I am using the Taranis X9D Plus with an XSR receiver mounted in the Speed Addict frame.
The Pilot cam will not fit in the Speed Addict frames. Out of the box, the frame fits the Foxeer HS1177 camera. With a change in the vertical camera side plates it will fit the RunCam Swift & Owl Plus cameras. The HS1177 seems to be the benchmark for fpv racing cameras with the RunCam Swift almost the same but I feel the Swift has little better picture and light handling. I use the RunCam Swift, the camera settings in it's OSD menus are more easily accessible with the Swift & Owl Plus. Also the Pilot camera is CMOS, not CCD which handles changes in lighting better. And with analog video, the 720p would never be noticed.
Browse CatalystMachineWorks.com, he carries the frames, cameras, escs, FC board a vtx that fits well, the Swift camera side plates, and more. I recommend the Mantis F3 board. The Kombini board has a built-in 150a power distribution, transponder, buzzer and other features. No experience with Kombini but I've heard lots of good things about FuriousFPV who makes the Kombini.
Another FC option is the Dragonfly32 flight control board which is a Naze 32 board (I've been told rev.4), naze boards are everywhere with several names.
