I have used the emax eco series motor (eco II, 1700 KV) for my vtol, and I can tell you that these motors consume a lot of power. I also saw on the official EMAX website that the motor you selected draws a maximum current of 56 amps. so, I would suggest choosing a higher-rated ESC, like I am using a Ready to sky 80 amp ESC
Though if you are using prop on the spec sheet it only shows 33amps...

Solid, Emax III 2808 1300kv w/ 6s Lith-ion. Got all my parts picked out in Aliexpress but my card went into fraud prevention and so I have to convince them it's not a stolen card. Here's my starting components, there is still time to select different if advised.

TX16S MKII V4.0 Hall Gimbals ELRS

Matek MATEKSYS F405 WING V2
RadioMaster RP3 V2 ExpressLRS 2.4ghz Nano Receiver
MATEK Mateksys GNSS M10Q-5883 GPS Magnetic Compass

EMAX ECOIII 2808 Brushless Motor 1300KV
6Pairs(6CW+6CCW) Gemfan Hurricane 7035 7X3.5X3 3-Blade Reinforced PC Propeller
40A ESC OPTO 2-6S Brushless ESC
EMAX Official ES08MA II 12g Mini Metal Gear Analog

6S 30C High Rate Drone Lithium Battery Series: 22V (4000mah)- XT60 Connector (+ what looks like an 8ish pin FC power cable)
"25.2V 5A 10A Li-ion Fast Charger For 6S 21.6V 22.2V Lithium Electric Tool Battery Charger DC XT60" Chinesium

Is there any other core component to get R&D done? I think I'm going to worry about a nice Moon light FPV camera once I'm confident in flight characteristics.
Looks pretty good beside the couple things already mentioned👍 (Good idea on the moonlight😆👍)

I think the data on the spec sheet is tested in a controlled environment. In real-world conditions, you also have to account for other factors. I’ve often noticed that motors tend to draw more current than what’s specified in the datasheet, even when you run them with the intended battery and prop

It will draw maybe 10% more cold, resistance/actually impedance is less. Chinesium electronics do not work to published specs so add as a minimum 20% to keep smoke contained. Always buy bigger than you need, because..... I have some .010 gasser motors that are practically worthless for flying. Stop the prop from spinning and it will draw 20% more current, get hot, lets out the magic smoke. It's only too big if A: it wont fit, B it's on fire.
