Help with first build

[m3sgal]

I'm considering doing my first build as a learning experience. My goal is a digital sub 250g cruiser with light acro. I'll start with Betaflight, but I plan to move to iNav. I don't see myself attaching a GoPro anytime soon, but would rather use the Air Unit or DVR (or maybe an Insta360 Go). Here are the components that I'm considering:

Diatone Roma F4 LR Frame
Holybro Kakute F7 Mini V3 + Tekko32 F3 Mini 45A 4-in-1 ESC
XT30 Wire
Emax Eco 1407 3300Kv
HQ Prop 4x2.5x3 V2S
Beitian BN-880 GPS & Compass
DJI Air Unit (but holding off until we get the next version)
LiPo 850 4s (but it is difficult to find one in stock here)

I'm not sure which LiPo charger to get, but I'd want something that is small and portable. Not sure if I'm missing anything, or if what I've listed need some changes, so would be greatful to have your input.

I'm a newb... why the XT30 rather than XT60? Is this simply to keep the weight down?
From what I've seen, the same battery with an XT60 is more readily available and often cheaper.

I doubt it will help with weight. It is just my preference to keep it compact. Unless I'm going to use 6s battery, XT30 will be good enough. Having said that, I actually changed many things about this build, including the change to XT60 for the same reasons you stated
