Eagle tree question.

[E-Revonut]

Just wondering if anyone knows the minimum voltage for an Eagle tree V3? I tried to do a run with my single cell lipo in my carpet car but it didn't pick up anything. Didn't try it again so I'm not sure if it was a mistake on my part or if it needs a higher minimum voltage. I tried finding some info on their website but had no luck, they only seem to give the max voltage
