so i finally pulled the trigger on a prebuilt after years of building my own quads and honestly i dont know why i waited this long. got the geprc mark5 hd with the DJI O3 unit on it and the thing just... flies. like out of the box the tune was surprisingly decent, way better than i expected from a prebuilt. had to tweak the filtering a bit because there was some mid throttle oscillation when i was punching through some gaps but a small bump to the D term sorted it out mostly.

im running it on 6s and getting around 4-4.5 minute flight times which i know isnt amazing but the packs i have are older 1300s so that tracks. curious if anyone else has this frame and whether you went stock tune or redid the whole thing from scratch. also wondering if the frame arms are as fragile as people say, havent binned it hard yet but im a bit nervous about the arm thickness compared to my old builds.

yeah ive had the mark5 for a few months now. the stock tune is actually one of the better ones ive seen from geprc, they clearly put some time into it for once. i did end up doing a full betaflight tune anyway just out of habit but honestly the stock one wasnt embarrassing. the arms though... yeah they are a bit thin. i cracked one on a pretty medium hit, nothing crazy, just clipped a tree branch at like half throttle. replacement arms arent too expensive but its annoying. i ordered a couple spares as soon as it happened.

on the flight time thing if you get some decent 1350 or 1500 6s packs youll probably squeeze closer to 5.5 depending on how hard you fly it. the motors are pretty efficient for 2306s.

not on the mark5 but i went from building everything to grabbing a diatone roma f5 v2 prebuilt last year and same feeling, like why was i spending 3 weekends soldering when i could just fly. the tuning thing is the only part that still takes time regardless of prebuilt or not tbh
