I am using hw 1S too. Very very good. I think much better than lrp v2. Lot of my friends have issue with the LRP... but my HW never have any problem. ;)
I only play 8min. after I check the battery around 3.5-3.6V. But the ESC is very hot. even with fan if I play for around 8.5-9min the ESC will be too hot and cutoff...... I use x12 3.5T motor with 12.25mm rotor, 31mm roll out. Maybe I should try 4.0 or 4.5T motor.......
