Two days of prop testing! The HQ 5×4.3×3 are great for freestyle but I wanted more for the super light Astrox. Lookin’ at the HQ 5×4.8×3 the Kwad was over propped with it’s 2600kKV motors… the HQ 5×4.5×3 did a great job specially 0 to 50 throttle but handling was tough so. Andre convinced me to sattle up the good old DAL T5045 V2 and… top speed is fine and smooth handling from 0 to 100 throttle. Also cam tilt is now on 50 :-).
