500x flight times and batteries.
I just ordered a 500x Super Combo. Any suggestions on battery pack size and their flight times for 3d style?

The largest battery will be a 6s3000 mah,, check the manual for dimensions. Depending on how hard you push it you can get from 6 minutes to as low as 3.spending time, paying attention

500x can take upto 6s 3300mah packs. For longer flight times switch to 5s 3700mah and run 100% throttle in IU.60% of the time, it works every time!

On the T500X, I use 6S 3300mAh which last 3mnts of flying. I fly somewhat hard 3D. A buddy setup his for hovering and lazy loop and roll and is able to get up to 7mnts flying.

What is your head speed or throttle %?

My Trex 500XT uses HobbyWing ESC with fan (I found this is important) calibrated with +/-100% range at 50%. With the 6S setup, my IU1/2 is 80% flat curve with Gov-Store. So far, the motor and ESC are running cool. I do back to back to back flying for 8 packs without any cooling period. Since the rpm is fixed in all idle up, I use IU1/2 (bank1/2 in FBL) for getting the cyclic response (Agility/Style/Gain/Optimizer/cyclic feed-forward, paddle-sim)

If you asked me, I would hate to lower 1 cell to 5S setup and running 100% as the rotor rpm varies by the voltage drop, defined by the battery I-V and impedance. End result of varying rotor rpm = varying cyclic response, cyclic start-stop, collective power. This is very annoying flying characteristic that I vigorously mitigate.

Hope this help, regards,
hhart

I am using 6s 3000mah Pulse batteries. HS is set at 3200 rpm on the Vbar Neo governor. My flight timer is set at 3:20 minutes.

NQNA, I'm still using my old radio w/o telemetry. I do use the VBAR Mini/Blueline/Neo, their FBL performance is phenomenal in pirouette. Unfortunately, my old Miniature Aircraft tachometer with the see through window broke a decade ago. From there on, I fly all helis by ear, feel the torque, collective and cyclic response.

Fortunately, the Hobbywing V4 (not any version below) has a very capable governor modes with P and I adjustment. These 2 parameters are enough to quench the rpm sag or oscillation in a fast load-unload situation.

Regards,
hhart
