This may not really help you, but I fly 6s on my Gob700 regularly
and it flys beautifully! 710 blades,500kv....everything seems to stay
happy and cool.
I would try it if it were mine....at least once. On that machine you
may be flying 14s?? If so, maybe a 7s or 8s might hit the sweet spot.
Of course depending on what type flying you do. And the esc should be
fine, you are only going way down on amps as your headspeed comes down.
I was only going to 'try' it once when I first got the goblin, knowing it was a very heavy heli compared to my Logos; NEVER expected
the results......and have never looked back since
