okay so ive been lurking here for like 6 months watching build videos and i think im finally ready to pull the trigger on a 5inch freestyle build but i want someone to sanity check my parts before i order everything and realize ive made some dumb mistake

frame is a TBS Source One v5 because its cheap and supposedly pretty easy to work with for a first build. motors im looking at the Xing2 2306 1700kv with 6s which i know is a pretty common choice. for the stack im thinking the Mamba F7 with the matching 55a ESC stack, and then a Caddx Ratel 2 for the camera. running DJI O3 for video because i already have the goggles from when i had a Avata.

the thing im not sure about is whether the 1700kv on 6s is gonna be too much motor for a freestyle build or if i should drop to 4s and go higher kv. ive seen people argue both ways and im going in circles. also not sure if Source One is gonna flex too much and cause issues or if thats overblown

battery wise i was just gonna grab some Tattu R-Lines and call it a day

parts list looks pretty solid honestly, nothing there that jumps out as a mismatch. the 1700kv on 6s question is one of those things people genuinely disagree on but for freestyle i actually prefer it ? you get a bit more torque low end compared to running like 2400kv on 4s, feels more planted when you're doing power loops and stuff. the tradeoff is efficiency but for 3-4 minute freestyle packs who cares really

Source One flex thing is a bit overblown for casual freestyle, like yeah its not a HD fiberflex or whatever but unless youre doing really aggressive racing or you're heavy handed with tuning it'll be fine. i built one last year and flew it for months before i broke it crashing into a tree, zero issues with frame flex affecting the tune

one thing id change is the camera, Ratel 2 is decent but if youre already on DJI O3 you might as well just run the O3 air unit camera rather than mixing analog and digital. unless you specifically want analog as a backup option

im also on a first build right now so take this with a grain of salt but i went with the Mamba F7 stack too and the documentation for it is actually pretty decent compared to some other stacks ive looked at. betaflight setup wasnt as painful as i expected

the tattu r-lines are good but they're kinda pricey, i ended up going with GNB and honestly cant tell a difference so far but i havent really pushed them hard yet
