The new connector is very new. The people who has it, haven't verified if it's the ultra micro connectors widely used...or the larger version used on the mCPX. Ernuckle2 has purchased one to find out. Still awaiting delivery. I think this question has come up a couple of times within the last few pages. At this point, it's anybody's guess. But if it is the smaller micro connector widely in use, then it's pretty cool.
The early days, it was hard to source the v911 battery. Nowadays, it's easier to find. So I wouldn't let that deter you. It's a great first heli if you haven't flown a FP before. Worth just having in the collection if you already own others. Hard to beat for the price.
On long threads, I like to read backwards.
