okay so ive been flying whoops and tiny hawks for like a year and a half and i finally decided to just commit and build a proper 5inch freestyle quad. ive done a ton of research but the more i read the more confused i get about matching motors to ESCs, like everyone has an opinion and half of them contradict each other.

im looking at the Speedybee F405 stack which seems pretty popular right now and for motors i was going to go with either the T-Motor F60 Pro IV 1750kv or maybe the Brotherhobby Tornado T2 2306 2450kv. frame is probably gonna be the Apex or maybe a TBS Source One since its cheap enough that i wont cry if i bin it.

my main question is ? is the 45A ESC in that stack gonna be fine with 1750kv on 6S or should i be looking at something beefier? i keep seeing people say you should always have headroom on the ESC but then other people say 45A is plenty for 5inch freestyle. also not sure if i should even bother with 6S at this point or just do 4S and keep it simpler while im still learning the build process

45A is gonna be totally fine for 5inch freestyle on 6S, people way overthink this. like unless youre running massive props or doing insane power loops back to back the ESCs arent gonna break a sweat. i ran a 40A stack with 2306 motors for ages and never popped anything. the F405 stack is solid, good choice there.

id actually suggest going 4S for your first build just from a practical standpoint ? not because 6S is hard or anything but batteries are expensive and if youre still dialing in your tune youll go through a lot of packs. 4S packs are cheaper and you can get more of them for the same money. once you know the quad flies well then switch over. also the Tornado T2s are great motors, used them on two builds, no complaints

source one is kinda flexy tbh, i built on one and regretted it after my first proper crash. the arm flex messes with your tune more than youd expect. apex is a better starting frame imo even if its more money. just something to think about before you order
