hi all, i hope i can find a solution to this issue i have with my dyi quad. not th efirst built but my first with APM.
here's my config
(4x) SunnySky V2216 – 800kv
(4x) 11x4.7 props (APC clones)
(4x) ESC Mystery 30A BEC
Frame style DJI 450 (clone)
Battery Lipo 11.1 – 3S – 5500mah - 35C (brand Floureon)
+ sonar + optflow + 3rd radio + landing skids + GoPro + Gimbal
Total weight with including battery: 1.87kg
based on brand specs I thought the SunnySky had something like 500g thrust each at 50% Throttle... that's why I thought I could lift a 2kg quad easily...
but my APM dataflash logs should that I need 75-80% throttle to hover...(~790 value)
and my battery last only 5minuts where i know other users have flown 8mins with 3S and same motors...
what or how should I investigate my issue?
I heard someone said that clone APC props are not as good as real APC and i can lose almost 200g thrust each prop (diff between fake/real apc)... it this true?? does it really effect the thrust so much a low quality prop??
should I try with different ESCs?
should I change props?
should i get a different battery?
i'm bummed... i thought this 800kv motors were very strong...
