Hello, I have the T-Rex 600 with the 600L motor and Align 75A speedcontroller. My battery is a 6S2P 4400MAH 20C Burst pack. My BEC battery is the Align 2S lipo. This is my first electric heli, so I want to know if I am headed in the right direction regarding proper temps and setup. I want to make sure everything is good before I purchase a really high quality battery like the EVO packs. Keep in mind that the pre-flight temps and voltage on the battery packs were taken 20 minutes after charging.

This flight was for 5 minutes of tail in hovering. The motor is running in governor mode at 80% throttle.

Outside Temp - 94 degrees

Pre-flight temps:
Battery Pack= 93 degrees / 24.9 volts
BEC= 92 degrees
BEC Battery Pack= 8.3 volts
Speed Controller= 92 degrees

Post-flight temps:
Battery Pack= 111 degrees / 22.7 volts
BEC= 100 degrees
BEC Battery Pack= 8.2 volts
Speed Controller= 125 degrees
Motor= 155 degrees (on side), 142 degrees (on bottom)

By these temps and voltage readings, does it appear I am headed in the right direction?

Any and all opinions would be very appreciated.

Thanks for your time!

Jay

I'm not exactly sure what kind of feedback you're looking for but your figures look good. A better battery should run a little cooler. You'll definitely notice the difference with a good battery.

Anyone else agree the temps//voltage look ok?
